Hi mmtuts, is there a way to replace the existing comments with the new comments instead of loading new comments (or in my case an image) onto the existing ones? This would help me immensely on the website I'm creating. Thanks for the tutorials!
Here is how :) In the AJAX code, add a second variable under "$commentNewCount", which has the current starting row nr from your database. So the variable will look like this, "$commentCurrentCount = 0;" because we load comment row 1 and 2 when we load the page. Then we also need to add 2 to our new variable, as we did to the $commentNewCount, and we do that the same place inside the click() function. Then afterwards you need to add the new variable in the AJAX "load()" function, together with the other data we passed to the PHP script, to make sure we can use it in load-comments.php. In the PHP script that runs after the AJAX call, change your LIMIT parameter in the SQL statement so it looks as follows. $sql = "SELECT * FROM comments LIMIT $commentCurrentCount, $commentNewCount;"; What happens in the new SQL statement, is that by adding another number to our LIMIT, we tell it not only where to end, but also which row the query should start at. Now it should work! Extra note: If you want to change the number of results that pop up when you load more comments, for example from 2 to 8, make sure you change the number both places inside your click() function when you add to your variables.

Excellent video with a very patient explanation that doesn't make the common programming "teaching" error of assuming that the viewer has so much background knowledge that the lesson has no actual value to them.
You can shows all data from database by one click of a button instead of pressing it for many times, and replacing show more comment button into less comment button after showing all data. Thanks for this video man, it helps.
For anyone looking for the SQL query code: 'insert into comments (author, message) value ('Daniel', 'Lorem ipsum dolor sit amet, consectetur adipiscing elit. Praesent aliquet non orci sit amet rutrum. Vivamus tristique iaculis justo. Curabitur arcu tortor.'); insert into comments (author, message) value ('John', 'Lorem ipsum dolor sit amet, consectetur adipiscing elit. Praesent aliquet non orci sit amet rutrum. Vivamus tristique iaculis justo. Curabitur arcu tortor.'); insert into comments (author, message) value ('Daniel', 'Justi curabitur arcu tortor.'); insert into comments (author, message) value ('Jane', 'Vivamus tristique iaculis justo. Curabitur arcu tortor.'); insert into comments (author, message) value ('Connor', 'Consectetur adipiscing elit. Praesent aliquet non orci sit amet rutrum. Vivamus tristique iaculis justo. Curabitur arcu tortor.'); insert into comments (author, message) value ('Joe', 'Lorem ipsum dolor sit amet, consectetur adipiscing elit. Praesent aliquet non orci sit amet rutrum. Vivamus tristique iaculis justo. Curabitur arcu tortor.');'
There's still a way to replace $result = mysql_query with $result= $con->query($sql); I had trouble retrieving data from phpMyadmin by working with the first part but I knew how to do with the second one already! Thanks @mmtus for this tutorial. Very helpful. I've been looking for this way too long
Not sure if I watched this before. Ajax seemed not as important or difficult as php, sql, javascript, etc. But then, I found myself not progressing with Ajax for lack of good materials. Good thing that I found you AGAIN. Thank you Daniel.
I don't usually comment or like youtube videos but mmtuts is in my opinion the best channel to learn from. I used to face difficulties in web dev but after following his tutorials. I learn so so much and I now ace every exam in PHP and JavaScript. Please would you mind teaching Laravel?
You could’ve used limit and offset to load 2 more comments each time instead of gradually increasing the limit and loading all the comments again and again. Great tutorial for creating a perspective for a ajax beginner tho. Thanks!
Thanks elder brother. I am highly benifitted from this video. For the first time I successfully use the ajax to load mysql table. Keep it up. Best of luck from my side. Sorry for my poor English condition.
Hey dani I love your tutorial. That's why learned the php from you. I hope you notice me. I hope you next tutorial will be creating a crud usin REST api using vanilla javascript.
Mannnnn... I was so annoyed every time I tried to follow a video it didn't work at the end. Its my first website and I was so pissed coz I dont't like JS but you made things look so simple 😍 and easy to understand.. Thanks a lot bro 🙌🙏 u just made my day 😊
Excellent video tutorial. I’ve watched some of your videos and they have been quite educative and inspiring. Please, can you do a video on a Comment and Reply System using Php and Ajax? I need this video in order to fix the problem in the comment section of my website. Thanks in anticipation.
How to do the same things with element.... Like when i click on a different link the data should refresh accordingly. For example i have 5 links.. when i click on any link a set of data should comeup related to it... Please Help
Great tutorial! At the 16:00 min mark, one thing to consider is changing the code to commentCount += 2; Perhaps the long way is clearer and takes less explanation, but it's not preferred, at least not for the teams I've been coding with. Thanks again!
Great tutorial! But I have a doubt. Your query has only the LIMIT 2, but no OFFSET value. So will it keep fetch and load all comments right from beginning up to the limit each time? I mean.. When the limit is 2 and on clicking the 'show more comments' button, it is displaying 2 new comments. so totally 4 comments. Is that fetching only the new 3rd and 4th comment? Or it again fetches 1st and 2nd comments as well?
You're correct to question this. The better way to set this up would be to pass a $_POST['offset'] variable and have a hard coded limit and also not use the .load() but rather a $.post('script.php', {offset : $('#comments .comment').length}, function(result, status) { // loop and append to #comments here })); The .comment class would be a new wrapped around the author name and the message output.
Thank for the lesson, extremely comprehensive Please how can I replace the "load more button" to a scroll function? Such that once the page is scrolled down to the comments keep loading from set limit?
Thanks for making me overcome my fear for php oop through your series on the subject. You are my best tutor on youtube. please can you create a single page website using bootstrap and php? thank you, I look forward to it.
This is a great video. How different is the process when your trying to connect to an email database to return analytics on the campaigns? And the database requires a username and API key to be passed for authentication. Thanks!
It really depends on the purpose of what you are trying to output. 🙂 If the HTML should change depending on the PHP data, then echo the HTML out as well like you did in the first example. But if the HTML should remain static, then just echo the data like in example 2. If we talk security, as long as the data doesn’t come from an outside source (since we should never trust our users), then you don’t need to worry too much about it.
@@Dani_Krossing I don't know also if you'll see this comment.. But I reallly wanted to know how to add html elements from admin page to the main page of our php website.. For example, i have a video playlist, each video with an id.. and I wanted to add another video element with a vid source and id .. so what's the safest way... THANKS IN ADVANCE
Hi mmtuts, Can i request a video tutorial? Like you have a user accounts ang displaying data from your spicific account that those data you will noy found on the other account. #I'm one of your TH-cam follower
I get how to do so but what about a situation where I want to get the data from the database after every second or 2 and update the page . Won’t there be a lot of requests in my network tab? And if so will there be any side effects from that?

How can I refresh the comments automatic?
Will Murphy Hi. Thanks for the tutorial. I am display 1 result at a time but its not removing the first result when I click show more comments.
Its all in the Select * from table order by date "acceding or descending" Something like this. Just use the same Select statement each time.
