forms passing array variables in hidden field

[Anonymous]

<input type="text" name="fields[Email]" />

   $fields='';
   $values='';
foreach($_POST['fields'] as $key=>$value){
   $fields.=$key.",";
   $values.=$value."','";
};

//...few lines later...

print "<input type='hidden' name='fields[Email]' value='$fields[Email]'>";

with the input in a form submitted to my php
after processing it i want to call what's in fields
it outputs value='Array[Email]'

but when i reverse the order and ask for the var before the for each
it outputs value='123@abc.com'

I'm a little confused by your question. If you have a form field on the same page as PHP code, you're still not going to have to get at the submitted data until the form is submitted. It doesn't matter where in the page it is. Maybe if you could post your complete code and not just snippets.
