Hello all, I am trying to use the price field validation function found on GF’s Docs for a client’s silent auction: https://docs.gravityforms.com/gform_field_validation/#2-price-field-validation

The page is here: https://www.citylightsgallery.org/donate.

The form is directly under the video clip “We will make it.” The price field, “Your Bid,” which is revealed when you check “I want to place a bid,” should have a minimum value of $2,500.00.

This is my adaptation of the price field validation in the functions file:

    /*  Gravity Forms Minimum Amount  */
    add_filter( 'gform_field_validation_116_1', 'custom_validation', 10, 4 );
    function custom_validation( $result, $value, $form, $field ) {
        //change value for price field to just be numeric (strips off currency symbol, etc.) using Gravity Forms to_number function
        //the second parameter to to_number is the currency code, ie "USD", if not specified USD is used
        $number = GFCommon::to_number( $value, '' );
        $form = 8;
        $field = 1;
     
        if ( $result['is_valid'] && intval( $number ) < 2500 ) {
            $result['is_valid'] = false;
            $result['message'] = 'You must enter at least $2,500.';
        }
        return $result;
    }

I tested the form by entering a bid of $1.00 and it went right through. What am I missing?

Additional info: form ID is “8”, field ID is “1.”

Hi Mark. You should not be defining the form ID and field ID in your function. Those IDs come in to the function already. The form ID in your filter is 116, and the field ID is 1. Try this instead:

/*  Gravity Forms Minimum Amount Form 8, Field 1 */
add_filter( 'gform_field_validation_8_1', 'custom_validation', 10, 4 );
function custom_validation( $result, $value, $form, $field ) {
	//change value for price field to just be numeric (strips off currency symbol, etc.) using Gravity Forms to_number function
	//the second parameter to to_number is the currency code, ie "USD", if not specified USD is used
	$number = GFCommon::to_number( $value, '' );
	if ( $result['is_valid'] && intval( $number ) < 2500 ) {
		$result['is_valid'] = false;
		$result['message'] = 'You must enter at least $2,500.';
	}
	return $result;
}

Thanks Chris. Worked perfectly.
