I'm not sure where the mistake is. im using tutorial from this site https://www.codexworld.com/load-more-data-using-jquery-ajax-php-from-database/
I am making a comment system for my blog that I am creating and currently I have two problems with it. The form appears under every post. But only works on the top post. The rest of the forms simply don't work.
The another problem I have is that I'm using ajax and the form does add the record to SQL but I still have to refresh my page for it to show. I want it to show automatically straight away after it is added.
tl:dr
Two problems:
The only form that works is the first one under the first post, the rest simply don't work
Ajax doesn't automatically show the comments, need to refresh to seem them
Code:
JQuery
function post()
{
var comment = document.getElementById("comment").value;
var name = document.getElementById("name").value;
var mail = document.getElementById("mail").value;
var post_id = document.getElementById("post_id").value;
if(comment && name && mail)
{
$.ajax
({
type: 'post',
url: 'php/comment.php',
data:
{
user_comm:comment,
user_name:name,
user_mail:mail,
post_id:post_id,
},
success: function (response)
{
document.getElementById("comments").innerHTML=response+document.getElementById("comments").innerHTML;
document.getElementById("comment").value="";
document.getElementById("name").value="";
document.getElementById("mail").value="";
}
});
}
return false;
}

This is the first time I am playing around with AJAX :) so be easy on me Any help will be appreciated.
I tested all your code. It's working now. I commented it overall, so search after "NB" (lat. for "Nota bene") in codes, in order to see were I made relevant changes. I'll describe here some problems with it and I'll also give you some recommendations - if I may. At last I'll insert the three corrected pages.
Problems:
One big problem was, that you were using the $id_post variable in
the SELECT sql statement (in comment.php), which does not exist
in comment.php code.
Other problem: DOM elements had same ids. The DOM elements inside
loop-forms must have unique id attributes. You must always have
unique id attributes in html elements. Give them the form
id="<early-id><post_id>" for example.
There were also other problems in more places. I commented overall,
so you'll have to read my codes.
Recommendations:
Use mysqli_ instead of mysql_ functions, because mysql
extension were completely removed from PHP >= 7.0.
Use exception handling, especially when dealing with db access.
Don't write HTML code from inside php. Alternate php with html if you
wish, but don't do echo "<div class=...></div>" for example. This
is actually very important if you use an IDE which can format your
html code. If this code is inside php, you have no chance for this
beautifying process. therefore you can miss important html-tags
without knowing it, because your IDE didn't showed you where tags are
really missing in page.
In html tags: use same name as id. Example: id=mail<?php echo
$post_id; ?>, name=mail<?php echo $post_id; ?>. Exception: radio
buttons, checkboxes and all tags which can form a group. Then, each
tag would have a unique id, but all of them would receive the same
name.
Use '' overall and "" inside them. Maintain this "standard", you'll see it's a lot better than the inverse.
Corrected pages:
Index.php:

$con = mysqli_connect('<host>', '<user>', '<pass>', '<db>');

Good luck.
Your parent loop is generating several comments form and they all have the same id. Ids are supposed to be unique for the whole document. refer this. Perhaps this is causing other comment forms not to work except the first one.
Your second problem is not an issue. It is general behavior of how server works. When you are using ajax, it is sending data to the server which stores it in the database. Server's job is done. It cannot send the data back to the page and update the page content without refreshing the page. You can initiate another ajax call after posting to server in order to refresh the content of the page.
And though it is not related to the question. Try to be consistent with your use of single quotes and double quotes. You shouldn't randomly choose them. Decide on one and use them consistently. And yes do try to learn PDO or mysqli. I will suggest PDO.
I have the below code for User Rating & Comment system which is working fine, but user can post and rate again and again.
I want that if a user posted comment already he/she should not see the comment box but a message that " You have already posted comment on this page".
I tried by using the query in the Add-Comment.php but did not worked.
Need help to solve this issue. Thanks

You can construct a query to check whether the user has already posted a comment on that particular page or not, and display the rating and comment box accordingly. Here's the code snippet,
// your code
$results = $db->query("SELECT * FROM rest_rating WHERE sr_id = '". $id_post . "' AND user ='". $users . "'");
if($results->num_rows){
// user has already posted a comment
echo '<p>You have already posted comment on this page</p>';
}else{
// user hasn't posted any comment on this page yet
// display rating and comment box
?>
<div class="new-com-bt">
<span>Write a comment ...</span>
</div>
<div class="new-com-cnt">
<input name="starrating" id="starrating" value="1" type="number" class="rating" min=0 max=5 step=1 data-size="xs2" >
<textarea class="the-new-com"></textarea>
<div class="bt-add-com">Post comment</div>
<div class="bt-cancel-com">Cancel</div>
</div>
<div class="clear"></div>
</div><!-- end of comments container "cmt-container" -->

I was trying to parse the php data values which inside the while loop to the popup model .
Sample Code
<?php
include("connect.php");
$sql = 'SELECT id FROM products WHERE tag="mixed" ORDER BY id DESC LIMIT 5';
mysql_select_db('levels');
$retval = mysql_query( $sql, $db_server );
if(! $retval )
{
die('Could not get data: ' . mysql_error());
}
while($row = mysql_fetch_array($retval, MYSQL_ASSOC))
{
$id = $row['id'];
?>
<div onclick="showDialog('#dialog6');show_data();">
<div id="getid">
<?php echo $id; ?>
</div>
</div>
<?php
}
mysql_close($db_server);
?>
<script>
function showDialog(id){
var dialog = $(id).data('dialog');
dialog.open();
}
function show_data(){
var x = document.getElementById("getid").innerHTML;
document.getElementById("demo").innerHTML = x;
}
</script>
<!-- Popup Model -->
<div data-role="dialog" id="dialog6" >
<div id="demo"> </div>
</div>
Let's say if i have id => 1 to 10 , above code writing last 5 items from the table. which are 6 7 8 9 10 . ( it's working perfectly ) .
my requirement is to when i click the 7 it should parse 7 to the popup model. ( or let's say to the innerHTML of ).
it only parsing the first value ( 5 ) . to all onclick events when i click the each number.
PS : this is test using mysql not mysqli or pdo :) .
Thanks in Advance !
Try this. Hope it helps.
$sql = 'SELECT id FROM products WHERE tag="mixed" ORDER BY id DESC LIMIT 5';
mysql_select_db('levels');
$retval = mysql_query( $sql, $db_server );
if(! $retval )
{
die('Could not get data: ' . mysql_error());
}
while($row = mysql_fetch_array($retval, MYSQL_ASSOC))
{
$id = $row['id'];
?>
<div onclick="showDialog('#dialog6');show_data(<?php echo $id; ?>);"> <!-- Changed -->
<div id="getid<?php echo $id; ?>"> <!-- Changed -->
<?php echo $id; ?>
</div>
</div>
<?php
}
mysql_close($db_server);
?>
<script>
function showDialog(id){
var dialog = $(id).data('dialog');
dialog.open();
}
function show_data(y){ // Changed
var x = document.getElementById("getid"+y).innerHTML; // Changed
document.getElementById("demo").innerHTML = x;
}
</script>
<!-- Popup Model -->
<div data-role="dialog" id="dialog6" >
<div id="demo"> </div>
</div>

So i am haveing this page where it is displaying articles andunderneet each article it will have a textarea asking allowing the user to insert a comment.I did the AJAX and it works fine.Some of the validation works fine aswell(Meaning that if the textarea is left empty it will not submit the comment and display an error).The way i am doing this validation is with the ID.So i have multi forms with the same ID.For the commets to be submited it works fine but the validtion doesnt work when i go on a second form for exmaple it only works for the first form
AJAX code
$(document).ready(function(){
$(document).on('click','.submitComment',function(e) {
e.preventDefault();
//send ajax request
var form = $(this).closest('form');
var comment = $('#comment');
if (comment.val().length > 1)
{
$.ajax({
url: 'ajax_comment.php',
type: 'POST',
cache: false,
dataType: 'json',
data: $(form).serialize(), //form serialize data
beforeSend: function(){
//Changeing submit button value text and disableing it
$(this).val('Submiting ....').attr('disabled', 'disabled');
},
success: function(data)
{
var item = $(data.html).hide().fadeIn(800);
$('.comment-block_' + data.id).append(item);
// reset form and button
$(form).trigger('reset');
$(this).val('Submit').removeAttr('disabled');
},
error: function(e)
{
alert(e);
}
});
}
else
{
alert("Hello");
}
});
});

Again the problem being is the first form works fine but the second one and onwaord dont work properly
try this:
var comment = $('.comment',form);
instead of
var comment = $('#comment');
That way you're targeting the textarea belonging to the form you're validating
ps.
remove the id's from the elements or make them unique with php, all element id's should be unique
