[SOLVED] Make users delete their OWN posts ONLY

3raser · November 8, 2009

When ever they click the red X on index.php, it deletes their posts and the X only shows up on their own posts. But when they enter index.php?id=50 in their address bar, it deletes post ID 50 even if it's not their own post. How do I stop this from happening?

<?php require "global_navigation.php"; ?>
<?php

If you store the users id in posts (which you probably should), you can do this instead:

mysql_query("DELETE FROM posts WHERE id='$delete' AND owner='".$_SESSION['id']."'");

3raser · November 8, 2009

I've added that, but it doesn't even delete the posts. http://www.commentbb.com/demo/

Code

<?php require "global_navigation.php"; ?>
<?php

if ($_SESSION['username']) {
echo ' <a href="logout.php"><img src="images/logout.png"></img></a> <a href="member_list.php"><img src="images/members.png"</a> <a href="search_input.php"><img src="images/search.png"></a> <a href="profiles.php"><img src="images/profile.png"></a> <a href="ucp.php"><img src="images/UCP.png"></a></b> <a href="acp.php"><img src="images/acp.png"></a> <a href="modcp.php"><img src="images/modcp.png"></a>';
}

<?php

do you ever create a $_SESSION['id'] variable? and is owner the correct column you should be referencing?

3raser · November 8, 2009

do you ever create a $_SESSION['id'] variable? and is owner the correct column you should be referencing?

$_SESSION['id'] should be ['username'], I've changed that. And I thought owner was some command. - It's suppose to be name.
