16.4 - Advanced Validation Rules

You can use two different ways to check field errors using PHP (For example you can add validation to check if Field1 < 100 and Field2 < 100)

• Using WooCommerce Hooks, please read the article here
• Using WPC Hook (Described in this article)

This example code will work for WPC >= 2.3.0.

You can add this code by installing Code Snippets Plugin

function custom_awspc_filter_calculate_price_errors($errors, $params){
 	 $calculator	= $params['calculator'];
  	 $userData		= $params['userData'];

  	 /* Applying rule to calculator with ID 6 (Get the ID from the Edit page of the calculator in the URL bar) */
  	 if($calculator->id == 6){

	   /* Check if Field 1 > 100 && Field 2 > 100 */
	   if($userData['aws_price_calc_1'] > 100 && $userData['aws_price_calc_2'] > 100){
		 
		 /* Display the error */
		 $errorMessage					= "Field1 must be < 100 and Field2 must be < 100";
		 
		 $errors['aws_price_calc_1'][]	= $errorMessage;
		 $errors['aws_price_calc_2'][]	= $errorMessage;
		 
	   }
	   
	 }
  
  return $errors;
}

add_filter("awspc_filter_calculate_price_errors", "custom_awspc_filter_calculate_price_errors", 10, 2);

$params is a PHP array with the following:

• $params['priceRaw']: The result price without formatting
• $params['product']: The product
• $params['calculator']: The calculator
• $params['data']: The user data (Some values could contain ID instead of real user values)
• $params['userData']: The user data without any transformation
• $params['outputResults']: The output fields
