eval an html form field

mgwalk

I have a field like this the 12 is an item id attached to the name field I want to pick it up on the post.

<input type="checkbox" name="name12" value="12" />

When I submit it I try

if(isset($_POST['name'.$myid])) // <-- this never is works always not set...
   {
   // I can not get here even if the name12 is set...
   }
else
   {
   // I always get here
   }

What am I doing wrong or how do you get this to work.

Thanks

<input type="checkbox" id="name12" name="name12" value="12" />

<?php
$ID = "name".$myid;
if(isset($_POST[$ID])) // <-- this never is works always not set...
   {
   // I can not get here even if the name12 is set...
   }
else
   {
   // I always get here
   }
?>

Try that.

Well, that wouldn't make any difference - it's just a more long-winded way of doing the same thing; what's originally posted should work, so the fault must lie somewhere in something that hasn't been posted.

Even if it worked, it could probably be simplified: If there are a whole bunch of checkboxes named "name10", "name11", "name12", etc., then naming them "name[10]", "name[11]", "name[12]" might make things easier: you could then get a list of "namennn]" checkboxes that were checked by writing "array_keys($_POST['name'])".
