copied!<p>I'm assuming your delete buttons are simple links. Your links must contain all the information to delete a post. One way would be to pass a post id as a GET variable (e.g. link="myurl.com/posts/delete?id=#").</p> <p>Your script would then at first make sure the current user is allowed to delete the post. For example:</p> <pre><code>$user_id = $_SESSION['user_id']; $post_id = (int) $_GET['id']; if(canDelete($user_id, $post_id)) { // assuming post_id is unique for every post $sql = sprintf("DELETE FROM group_posts WHERE id = %d", $post_id); mysql_query($sql); } </code></pre> <p>Of course, you'd have to implement <code>canDelete($user_id)</code> yourself.</p> <p>By the way, <code>"DELETE FROM group_posts WHERE $current_user = $id"</code> always deletes every record in your table. At first you're comparing if <code>$current_user</code> equals <code>$id</code> and if they do happen to be equal, your query would look something like <code>WHERE 1 = 1</code>. I think you mean <code>"DELETE FROM group_posts WHERE user_id = '$id'"</code></p> <p><strong>EDIT</strong>: It seems you want to use ajax for deleting your posts. I recommend using jQuery or any other proper javascript framework as it saves you time. Here is a link from the jQuery documentation describing <a href="http://api.jquery.com/jQuery.ajax/" rel="nofollow noreferrer">how to make an ajax call to the server</a> and a <a href="https://stackoverflow.com/questions/375356/ajax-delete-using-jquery">similar question</a> to help you understand better.</p>

Querying!
