 <?php 
 mysql_query("DELETE FROM `registration` WHERE `registration`.`uid` = ask") or die("query not working");?>
return true;
}
</script>

<?php  
     while ($user_field = mysql_fetch_assoc($userdata))    {
        $sak=$user_field['uid'];
        ?>
        <a href="edit.php?myid=<?php print $user_field['uid']; ?>">Edit</a>&nbsp;
        <a href="#" onClick="showDetails('<?php echo $sak; ?>');">Delete</a>
     <?php         
     }
?>

Not Passing value :(

You can use data attribute from HTML5 and retrieve that value via JQuery. See [this](http://stackoverflow.com/questions/5309926/how-to-get-the-data-id-attribute) Example. — AddWeb Solution Pvt Ltd, Oct 25 '16 at 08:26
JavaScript executes on browser not on server. You should use ajax to execute serverside functionalities. — Dipu Raj, Oct 25 '16 at 09:10

You need to add a parameter to your showDetails function like

showDetails(ask){
  alert(ask)

}

and remove the $ from the JS-Code. It's an PHP-Variable

Try this :

<script>
function showDetails(sak) {
   var uid = sak;
   if(confirm("Are you sure delete this id "+uid)) {
      return true;
   }
}
</script>

Try HTML5 attribute. PHP:

<?php  
while ($user_field = mysql_fetch_assoc($userdata))  {
  $sak=$user_field['uid'];
  ?><a href="edit.php?myid=<?php print $user_field['uid']; ?>">Edit</a>&nbsp;<a href="#" id="sak-anc" data-sak="<?php echo $sak; ?>">Delete</a><?php
}
?>

JS: just make sure that you need to include jquery library to use JQuery function.

$("#sak-anc").click( function() {
        var sak = $(this).data("sak");
        alert(sak);
});

You can get more detail from here. Hope this help you well!
