i have html form

i am using <a href="#" onclick="document.aa.submit()"> instead of submit button

my code will explain my problem better..

<html>
<form name="aa" action="aa.php" method="post">
<input type="checkbox" name="posts[]" value="1">
<input type="checkbox" name="posts[]" value="2">
<a href="#" onclick="document.aa.submit()">Delete</a>
<a href="#" onclick="document.aa.submit()">Move</a>
</form>
</html>

aa.php

<?php
print_r($_POST);
?>

results

Array ( [posts] => Array ( [0] => 1 [1] => 2 ) )

Now the question is:

How to know user clicked on delete or move?

Note:

i know if i used <input submit> it will fixes the problem

but i can’t use submit button for some reason

Note 2

the question is how to detect it by php.

Example:

    Array ( [posts] => Array ( [0] => 1 [1] => 2 ['submit'=>'delete']) ) 

if('delete'){
mysql_query("delete from...")
}
else{
mysql_query("update/move ....");
}

    You need to make some tweaks to the form so the Post value knows which option you are submitting

      <form name="aa" action="aa.php" id='aa' method="post">
<input type="checkbox" name="posts[]" value="1">
<input type="checkbox" name="posts[]" value="2">
    <a href="#" onclick="submit_function(this)" rel="delete">Delete</a>
        <a href="#" onclick="submit_function(this)" rel="move">Move</a>
        <input id="submit_type" type="hidden" name="task">
        </form>

    in js with jquery

    function submit_function( item ){
    if( item.rel == 'move')
    {
    document.getElementById('submit_type').value ='move'
    }
    else if( item.rel == 'delete')
    {
    document.getElementById('submit_type').value ='delete'
    }

    document.getElementById('aa').submit()

    }

    in php

     if( $_POST['task'] == 'move' )
{
//do move stuff
}

    if( $_POST['task'] == 'delete' )
{
//do delete stuff
}
