I have created a toggle button with jquery but I need to pass my $id so it can execute the mysql in toggle_visibility.php.

how do I pass my variable from my tag ?

Yes

$("a.toggleVisibility").toggle( function () { $(this).html("No"); }, function () { $.ajax({ type: "POST", url: "toggle_visibility.php", data: "id", success: function(msg){ alert( "Data Saved: " + msg ); } }); $(this).html("Yes"); } );
