Let us know if anything else comes up. Sometimes, the best thing you can do is take a break from looking at code and tackle it again after a short break. It happens to me all the time when I get too close to a project.

Instead of trying to add a filter to the "product" pricing field, I simply disabled the "quantity" field in the pricing field option, then added a "quantity" field that goes along with the "product". So 2 fields instead of 1, and I can set a minimum quantity on the "quantity" field. Well THAT was a whole lot easier than the past 24 hours ;) Thanks anyway! (Maybe that can be a future feature request: to have the ability to set a min/max value on the "product" field when the quantity is displayed, instead of breaking it up into 2 fields?)

You would have to convert it to a number and remove the currency symbol and whatnot to do a direct comparison using a greater than or less than operator. I think you can echo a variable and immediately afterwards put exit; and be able to see what is going on.

Docs to the rescue again - I'm not looking for "gform_field_validation", I'm looking for "<a href="http://www.gravityhelp.com/documentation/page/Gform_paypal_config_validation" rel="nofollow">gform_paypal_config_validation</a>". Looking for the exact code I need to use, but I think I'm starting on the right path here.

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 $_POST values to see what, exactly, is being passed (which is usually how I troubleshoot stuff). BTW, here's the code I'm using: <pre><code>add_filter("gform_field_validation_1_16", "custom_validation", 10, 4); // field 16, form 1 function custom_validation($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; }</code></pre> 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.

I'm using the following docs on the site: <a href="http://www.gravityhelp.com/documentation/page/Using_the_Gravity_Forms_%22gform_validation%22_Hook" rel="nofollow">Using the Gform validation hook</a> <a href="http://www.gravityhelp.com/documentation/page/Gform_validation" rel="nofollow">Gform Validation</a> 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: <pre><code>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 $validation_result; }</code></pre> However, no matter what I do, it's absolute: either it ALWAYS returns false, or it ALWAYS returns true. It would help if I could print_r() or var_dump the values as they pass, but when I do that, it returns nothing. (for example, <code>print_r($field_value);</code> = 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?
