Instead of $_POST you can use rgpost, like this, if you want: <pre><code>[php] $submission1 = rgpost('input_6'); $submission2 = rgpost('input_31');</code></pre> That will do some sanitization for you. But your solution is perfectly acceptable. studio625 on "Is there a better way to write this double entry validation?" https://legacy.forums.gravityhelp.com/topic/is-there-a-better-way-to-write-this-double-entry-validation#post-45886 Mon, 09 Jan 2012 12:59:07 +0000 studio625 45886@https://legacy.forums.gravityhelp.com/ I'm building a registration form for a little league, and it's really important that the date of birth field is entered correctly, otherwise you have 13 year olds playing T-Ball. I want the users to enter the date of birth twice, then validate that both entries match. I managed to kludge together a custom validation that does this, but I don't like using the <code>$_POST</code> global variables. Is there a better way to write this? <pre><code>// Value of field 3_31 must match 3_6 and vice versa add_filter("gform_field_validation_3_31", "custom_validation", 10, 4); add_filter("gform_field_validation_3_6", "custom_validation", 10, 4); function custom_validation($result, $value, $form, $field){ $submission1 = $_POST['input_6']; $submission2 = $_POST['input_31']; if($result["is_valid"] && ($submission1 != $submission2)){ $result["is_valid"] = false; $result["message"] = "The date of birth fields don't match. Please make sure they are the same."; } return $result; }</code></pre>
