Validation issue with existing orders after quantity rule updates

I’m writing to provide an update on the order validation issue I reported. I found a temporary solution that unblocks order saving, and I wanted to share it with you.

The problem stems from the browser’s native HTML5 validation on HPOS order edit pages. It triggers on <input type="number" /> fields with values that don’t conform to the min, max, or step rules set by your plugin. Because the fields are also “not focusable,” the browser completely blocks the save process.

To work around this, I’ve injected a JavaScript script that removes the validation attributes from the quantity fields when the <b>”Update”</b> button is clicked. I added this code to my functions.php file to ensure it only runs on order edit pages:

<hr />

function fix_quantity_validation_issue() {
$is_wc_order_page = (isset($_GET['page']) && $_GET['page'] === 'wc-orders' && isset($_GET['action']) && $_GET['action'] === 'edit' && isset($_GET['id']));

if (!$is_wc_order_page) {
return;
}

?>
<script type="text/javascript">
jQuery(document).ready(function($) {
$('.save_order').on('click', function(e) {
$('input.quantity[type="number"]').each(function() {
$(this).removeAttr('min');
$(this).removeAttr('max');
$(this).removeAttr('step');
});
});
});
</script>
<?php
}
add_action('admin_footer', 'fix_quantity_validation_issue');

<hr />

This solution allows me to save existing orders and confirms that the issue is a client-side validation conflict, not a back-end error. I hope this helps you in developing a permanent patch for your plugin.

Thanks again for your support.

Best regards,

Alessio
