when use now, i've got undefined offset error
$custom_forms = $_post['custom_form']; foreach($custom_forms['label'] $key => $question) { echo htmlentities($question . ' - ' . $custom_forms['answer'][$key]) . '<br>'; }
<input type="radio" name="custom_form[answer][]" /> as far can see, using same name inputs.
since array doesnt bother text inputs.
but radio buttons work differently, have 2 groups of radio buttons same name, although css shows them 2 sepparate entities, when submit form parsed 1 radio button group.
my solution change name of radio inputs like
"custom_form[answer][input_<?php=$question['id']?>]"
