Hello everyone. I am designing a platform similar to a social media platform with a post, like and comment system. I am using jquery for likes and whenever I want to send a text message and want to like a post, only the first post is working but the like system for other posts is not working. How can I solve it. This is the index.php that contains the post and jquery code.

</body>

This is the favorite php code.
<?php
include("conn.php");
$name = $_POST['sugess'];
$sql = "INSERT INTO likes(postid, likes) VALUES('$name', '1')";
$result = mysqli_query($conn, $sql);
$sqlcount = "SELECT * FROM likes WHERE postid=$name";
$resultcount = mysqli_query($conn, $sqlcount);
$count = mysqli_num_rows($resultcount);
echo $count;
?>
So how should I solve it?
Similar content should apply to every post. I used a while loop but I still have the same problem.

Your problem is with the selector, it is an ID selector, with ID selector you can only select one element, try changing it to a class selector
to
it should be OK
<script> $(document).ready(function(){ $(".likings").click(function(){ var name = $("input").val(); $.post("like.php", { sugess: name }, function(data, status){ $("#like").html(data); }); }); }); </script>
