Custom validation issue

Hello all,

I'm having a head-banging issue. I'm using the following docs on the site:

Using the Gform validation hook
Gform Validation

and I'm running into an issue. Maybe I need another set of eyes or something - because the issue seems like it should be *so simple* to fix, but for the life of me, I can't get it to work. My filter looks like so:

add_filter('gform_validation_1', 'validate_min_group');
function validate_min_group($validation_result) {

	$form = $validation_result["form"];
	foreach($form['fields'] as &$field) {
		if(strpos($field['cssClass'], 'validate-min') === false) continue;
		$field_value = rgpost("input_{$field['id']}"); // retrieve the value

    	if($field_value < '15') {   //if the value is less than 15
    		$validation_result['is_valid'] = false;
    		$field['failed_validation'] = true;
    		$field['validation_message'] = 'A minimum of 15 tickets is required for group pricing.';
    	}
	}

    $validation_result['form'] = $form;
    return $validation_result;

}

However, no matter what I do, it's absolute: either it ALWAYS returns false, or it ALWAYS returns true.

It would help if I could print_r() or var_dump the values as they pass, but when I do that, it returns nothing. (for example, print_r($field_value); = doesn't come back at all.) But it just makes no sense at all to me.

I simply want to check if the field value is less than 15. if it is, i want it to return my error message. but like I said, for the life of me, it's absolute. It wither ALWAYS returns an error, or it NEVER does.

Can anyone see what I'm doing wrong here?

Thanks David :)

I just tried your code above, and I'm having the same issue - it's either ALWAYS false, or ALWAYS true depending on which way I put the carat (less than or greater than).

I'm still messing with the code, but I'm just not seeing why it's not seemingly recognizing the "<" value. That *seems* to be where the issue lies - in that area somewhere.

I swear, if I could figure out how to *see* the values returned by $_POST, it would help a lot, but I simply can't get this filter to return the $_POST values to see what, exactly, is being passed (which is usually how I troubleshoot stuff).

BTW, here's the code I'm using:

add_filter("gform_field_validation_1_16", "custom_validation", 10, 4); // field 16, form 1
function custom_validation($result, $value, $form, $field){
    	if($result["is_valid"] && intval($value) < 15){
        	$result["is_valid"] = false;
        	$result["message"] = "A minimum of 15 tickets is required for group pricing.";
    	}
    return $result;
}

pretty much exactly what you wrote. I just don't get why it's not doing what it *should* be doing.

EDIT: Okay - I think it has to do with the Paypal add-on. (This field is a Paypal pricing field.) When I put in a regular text field and run this function, it works perfectly fine. But the one I want to use it on is a Paypal quantity field. Guess I have more digging to do.
