A little help needed passing hidden values to next page

Posted on 16th Feb 2014 07:03 pm by admin

I have a page that has hidden values in a form.

example
Code: <input name='signupID' type='hidden' value='1' />
<input name='signupID' type='hidden' value='2' />
<input name='signupID' type='hidden' value='3' />
<input name='signupID' type='hidden' value='4' />

also within this form, the user enters details, name, phone number etc.

On the next page i need these hidden values to compare to the ID in the database so i can update the rows based on this hidden value.

I have obviously taken a wrong route here becuase i am getting warning after warning.

The code i have tried is this:
Code: if(isset($_POST['signupID'])) {
foreach($_POST['signupID'] as $item) {
echo "<input name='signupID' type='hidden' value='". $item . "' />";

but i get this: Warning: Invalid argument supplied for foreach() in C:wwwwasp-control.co.uk on line 79

The idea is that once the user has filled in the form, hits submit, next page compares the database to these hidden values "1,2,3,4" and then updates the database where the ID in the database is "1,2,3,4"

Any help here would be great
