Hello everyone, I would need to decompose string (always 27 characters long) of text field in all its characters and then pass them to tcpdf individually. I think we can solve everything by using "substr" php passed in the chronoform custom code block. Could anyone help me more specifically?
Thank you in advance.

Hi sanma,
​
What exactly do you need to do with the string? You will need some custom PHP to parse it.

Hi bob, actually I solved it with this code.
​
<?php
$form->data['zero'] = $form->data['Field'][0];
$form->data['one'] = $form->data['Field'][1];
.......
?>
​
But if the strings get longer I would like to find a recursive code that is always good.
