wppizza_filter_validation_rules

enabling one of the above rules

@param: array (all validation rules)
@return: array

example:

	add_filter('wppizza_filter_validation_rules','my_function');
	//to enable an exiting  rule above - let's say 'phoneUS'
	function my_function($validation_rules){
		$validation_rules['phoneUS']['enabled'] = true;
	return $validation_rules;
	}

creating and adding your own rules

example:

	/*-----------------------php (see also https://docs.wp-pizza.com/developers/?section=filters-actions-functions)-----------------------------------------------*/
	//to add your own rule - let's say 'my_rule'
	add_filter('wppizza_filter_validation_rules','my_function');
	function my_function($validation_rules){
		$validation_rules['my_rule']= array( 'lbl'=> 'My Rule', 'parameters'=>false, 'callback'=>false, 'enabled'=>true);
	return $validation_rules;
	}


	/*-----------------------js-----------------------------------------------*/
	// then add the rule like so via wp_footer action hook (or add it to an already existing js file)
	// adjust the validation pattern as appropriate for your validation rule

	jQuery(document).ready(function($){
		$.validator.methods.my_rule = function (value, element) {
   			return this.optional(element) || /^(?:\d+|\d{1,3}(?:[\s\.,]\d{3})+)(?:[\.,]\d+)?$/.test(value);
		}
		// adding a custom error message if validation fails instead of the default (not actually tested but should work just the same)
		jQuery.extend(jQuery.validator.messages, {
			my_rule: 'some error message,
		})
	});
