HELP – we just need someone to get validation to work on the product page add to cart – similar to how it already works for the user tmpl files (user/edit.php and user/edit_address.php).
!? I’m not sure which file to add the formvalidation to, maybe:
(1) template default_addtocart.php as it has the form in it, but the form class is used to autoupdate the price – I tried this but my attempt at adding the validation code and validation to the add to cart button fails so far.
(2) template default_customfields.php is the safest place as it only affects the custom fields but it might not pass the needed info to the form in the cart.

!? I’m not sure how to pass the required=”required” to the $field->display – I see hints at this in the user/edit_address.php form where it uses jquery. So instead I found I can edit the vmcustom tmpl files, for example:

plugins/vmcustom/textinput/textinput/tmpl/default.php

--- Code: --- <input class="<?php echo $class ?>" type="text" value="" size="<?php echo $this->params->custom_size ?>" name="customPlugin[<?php echo $viewData[0]->virtuemart_customfield_id ?>][<?php echo $this->_name?>][comment]" <?php if ( $this->is_required = "1" ){ echo 'required="required"';} // added by RM - if statement doesn’t actually work – simply adding the required=”required” would work well enough for me here ?>> 
--- End code ---

NOTE: the following edits will add is_required similar to is_hidden to all VM2 Custom Fields so anyone can easily make these required or mandatory (we still need help getting the validation working, see above)

Database Edit:

--- Code: ---ALTER TABLE `jos_virtuemart_customs` ADD `is_required` TINYINT( 1 ) NOT NULL DEFAULT '0' AFTER `is_hidden`
--- End code ---
