You need to look up something called AJAX. – Dave Mar 27 '13 at 00:47 — Dave, Mar 27 '13 at 00:47

You either use ajax or a named anchor in the link that sends the user back down the page when it reloads.

Named anchor: HTML Anchors with 'name' or 'id'?

Ajax method(one of MANY options): http://api.jquery.com/jQuery.ajax/

Remove this code immediately. This post gives one reason why. GET requests should never modify anything on the server, especially not deleting.

Instead, you should look into using AJAX. For example:

echo "<a href=\"javascript:remove(this,'".$nameskey."');\">Remove</a>";

And:

<script type="text/javascript">
    function remove(link,key) {
        var a = new XMLHttpRequest();
        a.open("POST","delete.php",true);
        a.onreadystatechange = function() {
            if( this.readyState == 4 && this.status == 200) {
                // assuming the link is a direct child of the element to be removed
                link.parentNode.parentNode.removeChild(link.parentNode);
            }
        };
        a.send("action=remove&key="+key);
    }
</script>

The issue isn't with the inherent nature of GET requests, the issue is the lack of security and input/user validation. — Scuzzy, Mar 27 '13 at 00:58
I'm not deleting anything on the server I just did a list of example some names and when I'm sure my list is complete(remove or adding) I submit my list.Of course my list come from a DB. — Alex, Mar 27 '13 at 01:04
