Chronoforms: loading up database values created by a multiselect

I’m in the thick of developing a complex step-based application form for a scientific organisation. I’ve decided to use Chronoforms as I’ve had nothing but good experiences from this extension.

Recently, I started working on the update process where users can return and edit certain steps before submitting.

A big thanks to Greyhead and his colleagues who created this awesome and flexible component.

Well, on my first step I had a multiselect which generated a comma-delimited list upon save in the database. When recalling the record, the multiselect didn’t seem to show the selected values. What I did to make it show up was simply introduce the following Custom Code in the On Load event.

<?php
$form->data['fields_practice'] = explode(',', $form->data['fields_practice']);
?>

This exploded the comma-delimited list to an array which was then usable by Chronoforms to populate the multiselect with the appropriate values.
