Validation failure clears form fields

Hi,

Just wondered if it was possible to get a quick update – is this something that is already possible or will be possible in a future version, or should we be looking to find a different solution?

Thanks,

Dan.

Hi Sark,

Thanks for the quick reply and it’s great that this can be in a future release.

I actually meant a quick update in terms of information rather than code but if you can provide a quick code update then even better!

Thanks again,

Dan.

Hi Sark,

Thanks very much for your help and for the code update – I have installed the update and enabled the Client Side Validation.

I am using the cloning fields feature (which is great), and I have an email address for each item added to the basket. So if the quantity is 2 then there are 2 email address fields, and I need to ensure that the same email address is not entered in more than one field. To achieve this I have in place my custom validation:

add_action('woocommerce_add_to_cart_validation', array($this, 'validate_order_meta_data'), 10, 3);

function validate_order_meta_data($valid, $product_id, $quantity)
{
	$values = array();

	// for each quantity of item added to cart check whether the meta value is unique
	for ($i = 0; $i < $quantity; $i++)
	{
		// request params are built from the field name and a base 1 index
		$request_key_index = $i + 1;
		$request_key = "email_$request_key_index";
		if (isset($_REQUEST[$request_key]))
		{
			$value = $_REQUEST[$request_key];
			// check for duplication
			if (in_array($value, $values))
			{
				wc_add_notice("Value $value appears multiple times", 'error');
				$valid = false;
			}
			else
			{
				$values[] = $value;
			}
		}
	}

	return $valid;
}

At the moment, if my custom validation fails then I see the validation error message shown, but my email address field values are cleared. Can I achieve what I want (my custom validation but not clearing the email address fields) using the new Client Side Validation?

Thanks again for your help,

Dan.
