I implemented a router for the framework by modifying the app class and creating a router.php file. This was done because the app I am developing was becoming complex. I’d like to share my implementation and I hope you’ll do a tutorial for that soon. Keep up the good work 🎉
its good you're able to come up with your own implementation, that means you're actually learning and improving. There are many ways to implement the router so as long as it works as you need it, that awesome!
I'm waiting for your sharing, it could be very important for me.
@@QuickProgramming can you add router to this MVC framework,
it will be very helpful for all type of projects.
thank you.
Nice tutorial
always the best teacher
Thank you :)
Hi. This is a wonderful tutorial. If instead of writing all the PHP code at once, it would be great if HTML was developed along with it. Like if after creating the MVC structure, it was started from the HTML home page and all the changes related to login (necessary PHP on this page) were made. And then if any changes were required on the login html page they would be done there. And then the PHP code that needed to be written would be written by connecting the logging or home controller to it. And then gradually the complex code would be added, sequentially.
Namespaces, triators and extra functionalities, such as validation rules, requests, posts etc, make this tutorial complex. It is quite difficult for beginners but probably intermediate learners will also find it difficult.
Thanks a lot
Love it, but I would like to see how you can add in this MVC a shopping page and cart that is connected with a database and handle it from out the admin. I'm new in this and want to learn more on how you can build up from out that base MVC. Product must contain size, color and so on, because when you search for a shopping page with check out nobody use these settings during when you want to buy something you pick your size and color
Thanks bro you are safe my life
you're most welcome
Thank you for the awesome tutorial. a suggestions, add Request and Response Class, then a simple validation class, You will have a beautiful MVC framework that work as a base for all small websites and APIs hence Response Class. Nevertheless, Great tutorial.
Thanks for the suggestions. i'll be making a follow up tutorial to add more functionality soon. a request class and validation class will be included and a few more classes to speed things up
Awesome content sir ..plz create a playlist for creating own php MVC framework
i'll be using this same framework to make alot of tutorials on converting templates to working websites, so yes there'll be a playlist🙂
Thanks for these great tutorials, I believe you are one of the best on youtube.
Do you have an Udemy channel, please? just for follow on complete production applications.
For example I have allowedColumns array and I found the issue for example if I insert user I need "created" and when I update I need "modified" but never both together. Does this mean I have to create a new protected variable ?
Good job sir
Thanks :)
Thank you sir
You're most welcome :)

You're most welcome 😊😊
Thank you for the lesson , please trying to impliment a website that has admin , how do i arrange the folders and controllers
should we use framework, how tradition php over using framework (like laravel) ?
i dont know why im getting a 0 value for the array with empty value, also $_GET['url'] didnt worked for me i had to use $_SERVER['REQUEST_URI'] did this things changed with php 8?
This is amazing! Could you do a video showing how to convert the social media project to this structure?
i used this framework to make a simple social website here th-cam.com/video/Hsph_-1EbPA/w-d-xo.html
Nice
Thanks
This is amazing brother, but I encounter a problem here, I am using a live server, php -S localhost:8888, and when I run print_r($_GET), I get an empty array, could you help me with that, please.
Sir which do u prefer framework laravel, symfony or codeigniter?

Awesome!
Great teacher of our time on TH-cam, Please can we have this tutorial for download letter, i need it so i can be practicing it when am offline
thanks, i think using the youtube app you can download for offline viewing
@@QuickProgramming Thanks, I have downloaded it for offline view. More grace.
Fresh stuff on youtube! Thanks! Question - can this MVC used in production?
yes it can. Thats what i use in my own projects, ofcourse with a few added features but no major differences
@@QuickProgramming Bro, I was looking such video sine 2017! Thank you for confirmation. Now it time to get hands dirty! I SUBSCRIBE!
can we use in production sir?
Hello Eathorne,
There is one thing I dont understand about model. When we execute the statement we give a array to execute() function. And now:
For example the prepaired query is:
SELECT * FROM users where id = :id
for execution we give information that [ 'id' =>4] - there is no expressions ":id" (with a colon).
How does the computer know that it should associate ":id" with "id"? W bindValue we should use (':id' , $x =4)...
the keys of the array must match the keys in the array. in this case the :id will be mapped to 'id' in the array
@@QuickProgramming Unfortunately, I still don't understand :( does this mean that the computer will look for the most similar key? It doesn't have to be identical? Does prefixing the key with a colon have any meaning here?
@@akordeonista the colon is there to tell PDO that the text is a variable to be taken from the array. without the colon it wont look in the array
@@QuickProgramming OK, thats clear, thank you
Hi Eathrone,
Why do we use 'require' instead of 'include' in that case?
You use include if the file you want to include is optional. Include will throw a warning if the file is not found but the code will continue executing. When you use require, the code stops executing when the file is not found. It throws a fatal error. I prefer require in this case so the cod doesn't continue if the file inst found. You can use include if it suits your purpose better. It's just a matter of preference
@@QuickProgramming thanks a lot
Is this the one from udemy clone? Or simillar?
great content. you're teaching's really good. appreciate the zoom in/out, makes it easy to follow along and copy the codes afterwards. wanted to finish this in one go but got stuck for 2 days due to my assets files not being read. in case anyone come across the same problem where they can't load css/images/js just add the line before the last line in htaccess shown in the video:
RewriteCond %{REQUEST_URI} !\.(css|jpg|jpeg|png|gif|ico)$ [NC]
Youre most welcome and thanks for that HTACCESS tip, i'll test it out as well :)
i am so excited for the course can you make course about lumen microframework
I'll check it out
hello quick i need your advice i have learned [ html - css - php - mysql - basics of ajax - api - laravel ] what aslo i need to learn to be backend developer and i am junior by the way and what is the next steps to be pro from your opinion ❤❤❤❤
to become a pro, learn OOP. after that, all you need is actual experience. start building actual websites. ask people who need websites if you can build them one for free. even friends and family if possible. the experience you get from it is invaluable. you can then use those same websites as part of your portfolio when looking for work. people care more about your work experience
Hi, one another question if I can.
Why do we finish method without result by "return false"?
Could we use also "return true" instead of "return false"?
i finish with false so that if the query doesnt work, it will return false. this can be used inside if statements to know if the query worked or not
@@QuickProgramming thanks for explanation, apprieciate your engagement👍
What is that "show" function you use in Database.php? And thanks fot tutorial. EDIT: Found it :)
Thanks for the video, you are a great teacher, can I ask if it's possible to send data with Ajax from login page to controller Login in this MVC ? I have tried, but failed.
sure its possible. the code below will send data to the controller of whatever page you're on.
let xhr = new XMLHttpRequest();
xhr.addEventListener('readystatechange',function(e){
if(xhr.readyState == 4 && xhr.status == 200)
{
alert(xhr.responseText);
}
});
xhr.open('post','',true);
xhr.send();
to send to a specific controller, add the full path to that controller in the open part like this:
xhr.open('post','/home',true);
ROOT represents the absolute http path to your project,
e.g localhost/mvc/public
@@QuickProgramming I get a way to pass the ajax Post variables to the controller page, however, when trying to instant the Class I receive a error: Class "Login" not found in C: \xampp\htdocs\MVC\app\controllers\Login.php:12
This video is good. However I am having issues with the .htaccess and rewrite of the URL. For mine, is not rerouting the url to the index page. I have confirmed that mod rewrite was enabled. Any other suggestions about this?
what server type are you using? htaccess files only work with apache, so if its a different server then that could be the problem
@@QuickProgramming I am using Apache. I did figure it out. The AllowOverride directive was set to None. When configured in this manner, htaccess is useless as Apache ignores it. Had to change it to All and then the htaccess file was recognized
Thank you so much, it's greate.
A Question can you please name your controllers like HomeController or ProductController instade of Home and Product?
Because we are lost always bettween models and controllers as the file has the same name.
I tried to change but it takes an error.
there's a better solution with namespaces which we'll get to eventually
@@QuickProgramming ooo a teaser of things to come!
The routing is fine but it is how Codeigniter does it. Laravel does it differently and is more robust cause you can clearly define the request method and map the appropriate controller method. With codeigniter example your can’t tell if its a get, post, patch etc without doing additional check. Anyway, it’s good if you are just beginner learning how it works as this is one way to do it.
in this you can also specify the method because the second item is the method, e.g in this link, 'edit' is the method 'website.com/product/edit'.
laravel is too complex for no reason. code igniter is slightly less complex, so i prefer it. Sure laravel can specify if its a GET or POST request but whats the real world application of that? it just creates a lot of 'page not found' scenarios. better to check using the request class or server method. The complexity of laravel is what i try to avoid by creating my own framework. if i copy laravel exactly then its better i just use laravel because it already exists. i could save time. in the end its all about preference i guess, i prefer making things myself, that way am not lost when a clients wants to change anything
I had a general error when attempting to Insert or update around the 2 hour mark in the video. Changing the line in Database.php if(check) to if(check > 1) fixed it. I dont know if anyone else had the same problem.
Thanks for leaving a tip to others
Hi sir, thanks for this tutorial!
how do not allow duplicates when entering data in your insert method?
you can use data validation to avoid that. then run the insert method only after checking if values are unique. i made a tutorial on form validation here th-cam.com/video/ymPlbgz6BoU/w-d-xo.html
Do u hvae udemy course complete project?
whats the difference between first and get row methods?
good question. the get_row function is for running a query, first function uses an array instead. using the first function you dont need to specify a table or even type a query. but there are times when you need to run a complex query and need only one result, thats when you use the get_row function
I had a problem with Model extends Database as a got a fatal error about not extending a Trait
you cant extend a trait, you use it instead. so put it luke this:
class Model
{
use Database;
//model functions and other code come here
}
Hello to everyone. Please solve my problem.
When we make a page named about-us then show page not found. Already create about-us.view.php page and Aboutus.php controller.
Plz help me
Controller file name.should be About_us.php, not Aboutus.php. please note the underscore
Very nice. When is next video using this mvc?
i'll be making a lot of websites using this framework, and we'll improve it over time to speed production times. there will be lots to learn from it
Thanks for the guide. It's really very easy to understand, good work!
I just have a question about the public directory. What is the best way to implement it so that it is no longer indicated in the URL? So that you only see your domain.
Many thanks in advance!
the public folder never shows up on the live server. its just there to organise your files better on your local machine. on a live server, you will be given a public folder there as well to put your files. thats where you will add the files that are in your local public folder too
@@QuickProgramming Ahh okay, thank you for your response!
You said in your video that it is not possible to load JS files inside the app folder. Couldn't this be used within the view Pages:
So the script is inserted as JS content within the head area.
Maybe they is a better way to insert the JS file for each view page over the controller class? So you don't need to put the script tag on each view page.
@@user-xv4fb5wz9i yes you can load JS & CSS that way but its inefficient. the reason we load JS & CSS files using the tags is because a user's browser can store them locally. This means they only need to be loaded once on the first page load. This is known as caching. loading the js as part of the HTML adds bulk to the code being loaded on every request.
furthermore, you cant do this for images since you can use the require or include on them. you'll still need to put them in the public folder. so why not just put your JS and CSS files in there too? i just dont see the point of trying to hide JS files when the user can still see the JS code no matter how its being loaded
@@QuickProgramming Thank you for your extensive answer! You are right that JS code is usually always used for client-side rendering. I understand why you used this folder structure for the software. My message does not aim to be more critical of this.
I'm just testing what I can do with PHP and vanilla JS to make my JS code less readable. I already use techniques like obfuscation and minification.
In the future I would like to further limit access to the code by running the code on the server and the client only holding the resulting HTML code. Like this example:
Restricted Access

Thanks for this amazing tutorial, I was following your tutorial step by step but in 3:28:55 I got this message Warning: Array to string conversion in E:\xampp\htdocs\mvc\app\core\Model.php on line 70 which is [if (!in_array($key, "$this->allowedColumns")], any advice please? thanks in advance.
do not put quotation marks around this part $this->allowedColumns. if you do that it tries to turn the array into a string, thats why its saying "Array to string conversion" in the error
@@QuickProgramming Thanks, that's right.
which one of the functions in the model class can to retrieve only the user id from a users table if no session has been set?
If there is no session then there is no user id. What are you trying to do? Maybe I can help
If you want to identify a user before they log in, you can use the session I'd. You can get that with this function
$id = session_id();
@@QuickProgramming yes thanks, i am trying to incorporate the email verification function with the mvc model but with my version i am inserting the a row in the verification table when the user successfully signs up at this point no session has been set but i want to insert the verification record for a specific user the users table and the verification table is separated therefore i am trying to insert the verification record where the user_id is equal to the user_id from the users table NOTE the user_id in the verification table is a foreign key from the users table
i tried this code to retrieve the user id from the user table
$user_id = 96;
$user_id = $user->first(['user_id' => $user_id]);
$verify_post['user_id'] = $user_id->user_id;
but it is hard coded to the user with id of 96 i want to modify this code s that is automatically selects correct user_id
how to remove the public folder in url? because currently .. /publicl/home
It's automatically removed when you put your project on a live server so don't worry about it when on your local machine. On your live server just make sure the contents of your public folder are in the public_html folder on the liver server. Do not put your app folder in your public_html folder, but outside it. Public folder = public_html folder. Search for a video on my channel on how to upload to a live server if you didn't understand my response
Thank you very much for quick reply. and thank you so much for this free but very informative video.
@@QuickProgramming
Is it different from the one you used in ecommerce?
yes, some things are different
Hi sir, I didn’t understand why you used unset in update and insert for data, why is it needed at all?
unset is used to remove all keys from the array that are not found in the database table or the ones you dont want to allow edits. if you remove unset, the function will create a query that has columns that dont exist in the table and so your query will not run. e.g if you have a user signup page, you will have the following fields:
username,
email,
password,
retype_password,
accept_terms_and_conditions.
but your database table will have only these columns:
username,
email,
password.
so when you do this:
$user->insert($_POST);
the function will create a query that includes all fields from your form. this query will not work because it contains "retype_password" and "accept_terms_and_conditions".
the unset part will remove these columns that dont exist in your table. you can also use this to make sure some columns are never edited, e.g the id column or date_created column. the unset part can remove these columns for you automatically from the query. watch this video where i use the framework to make a website th-cam.com/video/Hsph_-1EbPA/w-d-xo.html
@Quick Programming thank you sir, you are the best!
Did you use laravel framework in this project?
No, we made our own framework
thanks it was great. better to replace a silent keyboard and mouse, get prepared for the course. You have been copying/moving/making changes/forgot your code back-and-forth many times.
Am a busy person. I don't have the time to prepare for a course. I code in real time. The back and forth is important because it shows you how coding is like in the real world, rather than showing a perfect version which never happens in real life. However, there are plenty of shorter and well peppered videos online, so you don't have to watch mine
I can't seem to load pictures
Great tutorial. It really helps me. I really hate PHP, but in the same time I understand how cool is this language. Following this tutorial, it were many mistakes, and all of them was because I made mistakes in some name of variables (lost concentration I guess). Now I have an issue with inserting new user in the table. When I use show($_POST) it shows me the inputs, but freaking $user->insert($_POST) does not! What is the problem?
The problem is in terms actually. Accepting the terms is part of validate function. And after you put check mark to Accept the term it's value becomes the part of what you try to post. But there is no terms column in users table. If I remove accept the terms from validate function it works. But I don't understand why is it worked for you, man ?
i didn't finish the video yet, but just, at 20:12 it's a bad idea to indicate the directory of your admin files in here, in terms of security, because it makes it very easy for hackers to know where to search for your backoffice!
you can instead:
- ask google not to index these pages from google search central
- add php headers at the beginning of your files: header("X-Robots-Tag: noindex", true);
- add a meta tag in your html:
That's not the real admin folder. There will be no such folder on the website. All links are simply mod rewrites and not real folders

Do you happen to have a course where I can send emails from my website to my email address using PHP?
yes i do here th-cam.com/video/gortnFd7hgU/w-d-xo.html
But if you're using an online server, its easier because you simply need one function, like this:
mail("email@email.com", "a subject goes here", "your message goes here");
@@QuickProgramming Perfect, Thank you very much. Also, sorry to bother but do you have a way to upload and send attachments like images and videos with the email in PHP?
i want to write SELECT * FROM users WHERE id = 1 id != 2.
How can i modifiy where method inside model class ? its not working when i pass $model->where([id=1],[id=2]). Because array_marge replace delicate key. video Timeline 2:07:23
i think you forgot the '&&' like this:
SELECT * FROM users WHERE id = 1 && id != 2.
but this query doesnt make much sense because if id is 1 then its not 2, this means there is no need for the last part of the query which says 'id != 2'
@@QuickProgramming Thanks for the reply. Really appreciate.
actually, i try to build SQL with an "OR" operation like you.
like SELECT * FROM users WHERE name = 'A' or name = 'B".
$data_or = ['name' => 'A', 'name'=>'B']
$data_or showing only ['name'=>' B'] as an associative array can not contain duplicate key.
any idea how to build this SQL like you?
so far my code
if (!empty($dataOr) && isset($dataOr)) {
$this->sql .= '(';
foreach ($dataOr as $key => $value) {
$this->sql .= $key . ' = ? OR ';
array_push($this->val, $value);
}
$this->sql = rtrim($this->sql, ' OR ');
$this->sql .= ')';

I was wondering how would we go about templating when we have the same header and footer used on all pages without copying them on every page... Where would we use them? Would it be the index page, or would we create something else that gets pulled before and after each view?
thanks. you can load any view file, including the header if you save it as a separate file and then load it the same way you load other view files inside another view, e.g $this->view('header');
