I need to check the values of an input field, something similar to
if ((isset($_POST['ins_cont_fina'])) && ($_POST['ins_cont_fina']!=""))
The problem is that the 'ins_cont_fina' field is part of a repeated region and is formatted like this
<input type="text" name="ins_cont_fina_<?php echo $repCounter ?>" />"
I'm not great with array's at the moment and I think i need to check the values within an array to determine if any of the values state 'First Name', if they do, then the global var "$_POST['ins_cont_fina_?']" (which ever counter number it is) must be cleared.
Could anyone explain how this could be made possible please?
