Hey guys, make sure to add the ? in the shorthand of the if statement for the $submenu variable. I think Alec had cut this out right around 26:30. Thanks for these awesome tutorials!
Great tutorial now I'm trying to convert bootstrap 5 menu into wp_na_menu, but I'm facing 2 issue so far as I have a div before the UL and struggling to add the bootstrap classes to wp_na_menu any direction on how to do the conversion, thanks in advance
Hi Alex, thanks a lot for you lessons; they're so valuable but, as many other, I'm facing the issue "Declaration of Walker_Nav_Primary::start_lvl(&$output, $depth) should be compatible..." According to your suggestion, I've checked the repo in github but unfortunately it didn't do the trick. Here the fragment I've found over there: "function start_lvl( &$output, $depth ){ //ul..." which doesn't work; following some suggestion in the chat I've replaced that line with this one : function start_lvl( &$output, $depth=0, $args=array()): in this case, I got no errors but the menu has disappeared. Can you kindly give any clue?
Just a small piece of feedback - please keep your cursor in the middle of the recording screen (vertically) otherwise those of us watching with subtitles on are not able to see what you are writing (eg around 7:57, when you are including the Walker.php file). Thanks. Keep up the good work. :)
The coolest thing I've learned is the $var = (condition) ? [ true clause ] : [ false clause ]; it looks so neat. Also: thank you so much for the tutorial!
This is a great tutorial on walker classes as there really isn't much info even now in 2021 regarding this HTML tree manipulation, at least not on youtube. I followed both of your tutorials on this topic - this video (part 14) and also part 15 and it works great after I inspect the elements -no critical errors. However, I was wondering how to add an "ID" instead of a "Class" to different submenus elements so that I might use javascript later on to create a better mobile nav UX. So for example, adding an ID of dropdown-menu so it renders like the following:
Hi; probably it's because after years things have changed, but for me it does not work.. If I inspect the code, the submenu is there, and I can see the caret, but if I click I just open the first level.. and I can no see the second ones opened. I am using Bootstrap 5; is it enought changing data-toggle="dropdown" to data-bs-toggle="dropdown" ?
The indentation part isn't really required because dev tools on all browsers will auto indent. It all gets uglified once in production anyway. Other than that great tutorial :)
so I got this error: Warning: Declaration of Walker_Nav_Primary::start_lvl() should be compatible with Walker_Nav_Menu::start_lvl(&$output, $depth) I changed it to: Walker_Nav_Menu::start_lvl(&$output, $depth = 0, $args = Array) and seemed to fix it.....is this right?
Hello, I am from HK, a newbie developer... I used Walker_Nav_Menu::start_lvl(&$output, $depth = 0, $args = Array) , and it shown error, and I use Walker_Nav_Menu::start_lvl(&$output, $depth = 0, $args = Array() ) it seems works, or is it a wrong declaration? Thanks
Same issue :( I find this on github github.com/wp-bootstrap/wp-bootstrap-navwalker/tree/v3-branch, and it works very well . You can find similar class for Boostrap 4 ;) You can also use the walker.php that Alessandro used in "Create a Premium Theme" tutorial chapter 18. You can find this class in the git repo github.com/Alecaddd/Sunset-theme
Thanks so much for this very helpful series! I seem to have a slight problem and was hoping you could help. As soon as I started integrating the walker class, my carousel broke! :( I did read through the comments and see that you had updated the git repo ... any thoughts?
WordPress updated a bit the Walker Class since I did this tutorial, so there are some small changes that affect the theme a bit, but nothing major. I suggest you to check the walker class in my Git repo in the last lesson folder, that is the most updated and working one. Let me know if you fixed it.
Hi Alessandro, thank you for your tutorial, it's really helpful. I want to ask you, since i'm a newbie on wordpress, why the pagination not working when I set the page template as a static front page? It just leave the page blank. I'd be very glad if you can tell me how to fix this. Thank you :)
If you set a static front page you lose the default blog loop that prints your posts. Your theme is now returning only the info of 1 single page, the one that you set. The pagination works in the blog page, search result or archive page.
If you start the tutorial from the display_element() method followed by the start_el() method of the Walker_Nav_Menu class , you can let the viewers code along and check how classes and attributes modify the final ouptut step by step.
Since the Walker code isn't working, I'm just going to keep all of this code as "comments" and if you make an updated version of this video then I can refer back to the code. For now I'll move onto the next lesson. Thanks for your hard work. ^_^ For anyone else stuck on this make sure you adjust the header, functions, and walker files.
+Kyrae Jenkins Why is not working? What problem are you encountering? Did you check my source code on GitHub? Let me know, I'm sorry if you're having issues
+Alessandro Castellani my code tells me that on line 31 there is a sub-menu syntax error. and I noticed other people had the same issue. and you said that since this tutorial there was an update and that you would do a new video in the future so I figured I would skip this lesson until then. does the source code on github have the updated code?
Hi +kyrae Jenkins! When you said that you were stuck in this project do you this kind of error? Strict Standards: Declaration of Walker_Nav_Primary::start_lvl() should be compatible with Walker_Nav_Menu::start_lvl(&$output, $depth = 0, $args = Array) ?? If yes, then you should edit your wp_config.php file and set your 'WP_DEBUG' into false such as this define('WP_DEBUG', false); That is how I fixed my error. in this tutorial :)
+Serge Boyko Sure, you can use also include, but I won't recommend it. First you're using 2 functions ( include and locate template ), instead of only 1 (get_template_part). And second, get_template_part is part of the default API of WordPress and it's highly recommended to use that one during theme development. Happy coding!
thank you so much its very helpfull ,but i have problem my code how can i fix it Warning: call_user_func_array() expects parameter 1 to be a valid callback, class 'new description_walker()' not found in F:\php\htdocs\wordpress\wp-includes av-menu-template.php on line 706...
For anyone having a problem with the menu not showing up after doing this lesson just change the function start_lvl(&$output, $depth) to function start_lvl(&$output, $depth = 0, $args = array()) and comment out function start_el().
Hi,i have a doubt,i have 4 menus,in that about.php,courses.php,gallery.php.please tell me how to use conditional statements inside the page.php,thanks in advance
I'm not sure I got your question. So, you have 4 menus, I guess you want to show them dynamically based on the page, right? If that's the case, just assign each of those menus to a different menu location, and then call that menu location in the relative PHP file.
Mhhh, sorry, I don't think I get your issue. You have a walker nav class, did you require that file in the functions.php? Are you calling that class when invoking the wp_nav_menu?
My walkernav menu working without any issue so i dont style it yet. I mean i dont see wp-bootstrap-navwalker.php in your root directory. Do i need it when styling with your technique?
hii Alessandro Castellani in my code i am using this code its not showing any error but it's hiding my menu function start_lvl(&$output, $depth = 0 ,$args =array() ) { $indent = str_repeat("\t",$depth); $submenu = ($depth > 0)? 'sub-menu' : ''; $output .= " $indent ";
No need to write the same issue in multiple social media. Just writ a comment in a place and wait for the answer. I answered to you on my facebook page already.
how can i fix this- ( ! ) Parse error: syntax error, unexpected ''walker'' (T_CONSTANT_ENCAPSED_STRING), expecting ')' in C:\wamp64\www\wordpress\wp-content\themes\awesometheme\header.php on line 53
not working, same code, it shows ( ! ) Parse error: syntax error, unexpected ''walker'' (T_CONSTANT_ENCAPSED_STRING), expecting ')' and dreamweaver show error in line- 'walker' => new Walker_Nav_Primary()
It's a built-in method of WordPress. The $depth variable represents the location of a link inside your menu. If the link is at the first position, so it's not indented to anything and doesn't have any parent, his depth is 0. If an element is a child, the depth is 1 If an element is a child of a child, the depth is 2. And so on. WordPress automatically detects your menu structure and applies an incremental number ($depth) to your elements based on their location.
Check my source code on GitHub, I updated those few spots in the Walker Nav Class to work with the recent version of WordPress. You just need to add defaults to methods' attributes
i got it working, apparently i accidently created the file into another file.....but now im having another issue Declaration of Walker_Nav_Primary::start_lvl(&$output, $depth) should be compatible with Walker_Nav_Menu::start_lvl(&$output, $depth = 0, $args = Array) im also checking your source code for mistakes i might did
That's a recent depreciation of the new version of WordPress for the walker nav class. Simply update the attributes of the start_lvl method how suggested in the error. start_lvl(&$output, $depth = 0, $args = Array)
Hi Alex, thanks for a great video. I'm totally a newbie with no training or experience whatsoever, I'm learning WordPress for my own use only. Your series has been of a great assistance to me. However, I'm stuck. I'm receiving the error below, which I can't figure out how to solve it, I would appreciate if you could figure out for me what to do.

I've followed your lesson (and understood most of it!) but have ended up with a couple of error messages: "Warning: Declaration of Walker_Nav_Primary::start_lvl(&$output, $depth) should be compatible with Walker_Nav_Menu::start_lvl(&$output, $depth = 0, $args = Array) in C:\xampp\apps\wordpress\htdocs\wp-content\themes\Paulsfirst\inc\walker.php on line 49" "Warning: Declaration of Walker_Nav_Primary::start_el() should be compatible with Walker_Nav_Menu::start_el(&$output, $item, $depth = 0, $args = Array, $id = 0) in C:\xampp\apps\wordpress\htdocs\wp-content\themes\Paulsfirst\inc\walker.php on line 49" Line 49 is just the closing } (and I copied the code for walker.php from github to make sure it wasn't my typing) - Help please. Many thanks PS Your tutorials are great btw.
Cracked it - I found your link to the corrected code in one of the replies below: github.com/Alecaddd/WordPress101/blob/master/lesson_22/inc/walker.php Onwards & upwards
Hey Alessandro, to be honest your tutorials is very good im loving it! But my wp_reset_postdata(); is not working, kindly help me out and one more thing you are my wordpress teacher and my this teacher is awesome Love from Pakistan :)
+Mohammad Huzaifa Hi man, thank you so much for your positive comment, I'm really happy to hear that. What is not working with the wp_reset_postdata()? Is your WP_Query not reverting to its original status? Thanks for watching.
Thanks for this - although I have to admit this seems like a lot of work just to remove stupid little classes that are attached to the wordpress menus - it annoys me with all these CMS's when they put their own classes into things and you're like why don't you just produce raw html and allow the end developer to add their own classes on each block without having to go into PHP just to remove classes!
The default value is 0. If you want to check the current value based on the menu item location, simply add it to the output of the start_el method: $output .= $depth;
thanks, Alessandro. If the value is 0, I don't understand why. I have been looking through many tutorials and no many details are given. Your tutorial is the best I have found. But I still dont understand it all. Sometimes I think if it is really worth the effort to build a dynamic menu with PHP or just stick with a static one.
There're no such videos about Walker Classes in Russian. No one single good tutorial. You explain very good and speak clearly. Thanks a lot.
This is the only lesson on the walker class that i was able to understand. Thanks for the explanations!
Best resource on walker. Crystal clear. You surely have teaching skills! Thanks a lot !
+Daniel Dafoe Oh wow, thank you so much for this positive feedback :D
Hey guys, make sure to add the ? in the shorthand of the if statement for the $submenu variable. I think Alec had cut this out right around 26:30. Thanks for these awesome tutorials!
+Drew Cook thanks for flagging that out, I totally forgot but should be fixed in the git repo
This is the best walker class tutorial I've ever seen. Thanks a lot Alessandro.
+Nazar Dmutrah Happy to hear that! It's actually 1 year old, and small things have changed, I should do an update tutorial about it.
Happy Coding!
The way you explain things is great! Thanks for the video!
+theNoob Thank you so much for watching!
This tutorial is amazing! ur explanation and step by step is pure genius. Thank you!
Oh wow, thank you so much :D
Great Stuff. You are explaining the Walker Class very well. This is very helpful!
Thank you for the feedback, I still think that I could improve more.

if you want data- attributes to and and each data- attribute would be different to each different and what would be the solution?
Check my playlist on how to create a Mega Menu in WordPress. I explain how to tweak everything in details
No words, you rock . Thats all!
Ahahah, thank you :D
The indentation part isn't really required because dev tools on all browsers will auto indent. It all gets uglified once in production anyway. Other than that great tutorial :)
Love you bro :)
i am confused about widgets.. can we use the walkers to customize its output? thx again
I did a menu and it works perfectly fine in all devices except Android! Any advice is greatly appreciated!
Puzzling
so I got this error:
Warning: Declaration of Walker_Nav_Primary::start_lvl() should be compatible with Walker_Nav_Menu::start_lvl(&$output, $depth)
I changed it to:
Walker_Nav_Menu::start_lvl(&$output, $depth = 0, $args = Array) and seemed to fix it.....is this right?
Yes, correct. WordPress now requires default values for all the attributes of the Walker Nav Class.
I pushed an updated code on my GitHub repo.
Hello, I am from HK, a newbie developer...
I used Walker_Nav_Menu::start_lvl(&$output, $depth = 0, $args = Array) , and it shown error,
and I use Walker_Nav_Menu::start_lvl(&$output, $depth = 0, $args = Array() ) it seems works, or is it a wrong declaration?
Thanks
I've looked into the repo and I can't see that update...
Same issue :(
I find this on github github.com/wp-bootstrap/wp-bootstrap-navwalker/tree/v3-branch, and it works very well .
You can find similar class for Boostrap 4 ;)
You can also use the walker.php that Alessandro used in "Create a Premium Theme" tutorial chapter 18. You can find this class in the git repo github.com/Alecaddd/Sunset-theme
Hi. Alex. Thank you very much for the video. I see a search icon next to the menu. In which video did you insert it? :D
Hi, I implemented a couple of extra things during the live development sessions. You can check those videos in the playlist.
Cheers
Ok. I will. Thanks. :D
is it on Part 3?
Yes, it is on part 3 of live development session
Thanks so much for this very helpful series! I seem to have a slight problem and was hoping you could help. As soon as I started integrating the walker class, my carousel broke! :( I did read through the comments and see that you had updated the git repo ... any thoughts?

Hi +kyrae Jenkins! When you said that you were stuck in this project do you this kind of error?
Strict Standards: Declaration of Walker_Nav_Primary::start_lvl() should be compatible with Walker_Nav_Menu::start_lvl(&$output, $depth = 0, $args = Array) ??
If yes, then you should edit your wp_config.php file and set your 'WP_DEBUG' into false such as this define('WP_DEBUG', false);
That is how I fixed my error. in this tutorial :)
Great tutorial, as always!
You can also include template with "include(locate_template('path/to/template.php'));"
+Serge Boyko Sure, you can use also include, but I won't recommend it.
First you're using 2 functions ( include and locate template ), instead of only 1 (get_template_part).
And second, get_template_part is part of the default API of WordPress and it's highly recommended to use that one during theme development.

+Alessandro Castellani Didn't think about it like that. Thanks for explanation!
thank you so much its very helpfull ,but i have problem my code how can i fix it
Warning: call_user_func_array() expects parameter 1 to be a valid callback, class 'new description_walker()' not found in F:\php\htdocs\wordpress\wp-includes
av-menu-template.php on line 706...
Hi, this looks not related to the custom theme, but it's an error of your WordPress installation.
Be sure you installed WP correctly.
I again installed it solve this,but i have generated one depth and one submenus ,it will not give another submenus ..how can i solve this..
For anyone having a problem with the menu not showing up after doing this lesson just change the function start_lvl(&$output, $depth) to function start_lvl(&$output, $depth = 0, $args = array()) and comment out function start_el().
Awesome, thanks!
Thank you, it works. But why does the problem occurs !?
Hi,i have a doubt,i have 4 menus,in that about.php,courses.php,gallery.php.please tell me how to use conditional statements inside the page.php,thanks in advance
I'm not sure I got your question. So, you have 4 menus, I guess you want to show them dynamically based on the page, right?
If that's the case, just assign each of those menus to a different menu location, and then call that menu location in the relative PHP file.
Alessandro Castellani yaa exactly like that only, can u please give me some hints to do that
I explained that in this series if I'm not wrong. Showing how to create a menu with a unique location, and then call that location on a specific page.
Is this still valid for use in 2020?
Great tutorial thanks sir
You are welcome
Hi Alessandro, I noticed that the search is been changed to icon on the right from part 13 to part 14, is there is a missing part? Thank you
watch the live sessions playlist, it's in part 3 i think.
Thanks, I got it
Bravo! Worked a charm!!
Happy to hear that :D
Hi, the $submenu = ($depth > 0) ' sub-menu' : ' '; didn't work on mine. :(
You need ? before ' sub-menu', it's a ternary operator.
I have wp-bootstrap-navwalker.php in my root folder but i think we can't style navwalker with that way right? Do i need wp-bootstrap-navwalker.php?
Mhhh, sorry, I don't think I get your issue.
You have a walker nav class, did you require that file in the functions.php?
Are you calling that class when invoking the wp_nav_menu?
My walkernav menu working without any issue so i dont style it yet. I mean i dont see wp-bootstrap-navwalker.php in your root directory. Do i need it when styling with your technique?
THANK YOU ONCE AGAIN FOR GREAT CONTENT! :D
dear when i am adding this walker class in header.php , my menu items disappered. Please suggest.
Dear query is resolved i checked code on github. Thanks
Cheers
hii
Alessandro Castellani in my code i am using this code its not showing any error but it's hiding my menu
function start_lvl(&$output, $depth = 0 ,$args =array() ) {
$indent = str_repeat("\t",$depth);
$submenu = ($depth > 0)? 'sub-menu' : '';
$output .= "
$indent
";
No need to write the same issue in multiple social media. Just writ a comment in a place and wait for the answer.
I answered to you on my facebook page already.
how can i fix this- ( ! ) Parse error: syntax error, unexpected ''walker'' (T_CONSTANT_ENCAPSED_STRING), expecting ')' in C:\wamp64\www\wordpress\wp-content\themes\awesometheme\header.php on line 53
Check my source code on GitHub, you most likely have a syntax error.
not working, same code, it shows ( ! ) Parse error: syntax error, unexpected ''walker'' (T_CONSTANT_ENCAPSED_STRING), expecting ')' and dreamweaver show error in line- 'walker' => new Walker_Nav_Primary()
not be able to solve
Thank you very much
I wish you could tell me how the value of $depth is detected. That is what you say in the video. The value is detected. But how?
It's a built-in method of WordPress.
The $depth variable represents the location of a link inside your menu. If the link is at the first position, so it's not indented to anything and doesn't have any parent, his depth is 0.
If an element is a child, the depth is 1
If an element is a child of a child, the depth is 2.
And so on.
WordPress automatically detects your menu structure and applies an incremental number ($depth) to your elements based on their location.
Many thanks Ale. You know, despite Wordpress being so so old, many fundamental parts of the documentation are a piece of sh**
Great tutorial but. In current WordPress version, 4.9.8, seems that functionality is broken by few core WordPress files.
Check my source code on GitHub, I updated those few spots in the Walker Nav Class to work with the recent version of WordPress. You just need to add defaults to methods' attributes
Thank you
anyone having issues with the "require" part in the functions php file, i keep getting errors on this part
What errors are you getting?
did you check my source code on GitHub?
i got it working, apparently i accidently created the file into another file.....but now im having another issue
Declaration of Walker_Nav_Primary::start_lvl(&$output, $depth) should be compatible with Walker_Nav_Menu::start_lvl(&$output, $depth = 0, $args = Array)

That's a recent depreciation of the new version of WordPress for the walker nav class.
Simply update the attributes of the start_lvl method how suggested in the error.
start_lvl(&$output, $depth = 0, $args = Array)
I hope this isn't requiring to have in building your custom theme? :)

+Mohammad Huzaifa Hi man, thank you so much for your positive comment, I'm really happy to hear that.
What is not working with the wp_reset_postdata()? Is your WP_Query not reverting to its original status?
Thanks for watching.
hey brother i think you need to update the video.
And this how I use it with Tailwind CSS
Thanks for this - although I have to admit this seems like a lot of work just to remove stupid little classes that are attached to the wordpress menus - it annoys me with all these CMS's when they put their own classes into things and you're like why don't you just produce raw html and allow the end developer to add their own classes on each block without having to go into PHP just to remove classes!
Welcome to the convoluted world of the Walker Nav Class :P
What is the real value of $depth in this menu? Where is the value assigned? Its a pity there is a gap in the explanation. Good job overall, though.
The default value is 0.
If you want to check the current value based on the menu item location, simply add it to the output of the start_el method:
$output .= $depth;
thanks, Alessandro. If the value is 0, I don't understand why. I have been looking through many tutorials and no many details are given. Your tutorial is the best I have found. But I still dont understand it all. Sometimes I think if it is really worth the effort to build a dynamic menu with PHP or just stick with a static one.
that's not work
Check my github repo to compare it with your code
tnx
holy shit... that's a lot of code for just outputting one single navigation bar... -_-
