Didn't seem to make a difference when I tried it :-( Any thoughts on what I should try next?? ... dave <pre><code>function validate_mcss($mcss) { $mcss = trim($mcss); // check mcss value if ($mcss != "MCSS5") { // MCSS is not valid - must match MCSS5 return false; } }</code></pre> vlinkdave on "Gform_validation example" https://legacy.forums.gravityhelp.com/topic/gform_validation-example#post-30119 Fri, 15 Jul 2011 13:13:27 +0000 vlinkdave 30119@https://legacy.forums.gravityhelp.com/ I'm trying to follow the example but can't seem to validate my form field correctly. On the very simple form at <a href="http://www.selyestresssolutions.com/e-learning-resources/registration/" rel="nofollow">http://www.selyestresssolutions.com/e-learning-resources/registration/</a> I'm checking the form fields based on a cssClass to find the "ARAMCO" field that needs validation and then checking if the value entered is "MCSS5". Unfortunately the form continues to give me the error message that the value inserted is not correct. Can you point me to my logic or coding error? I think I'm close :-) Thx... dave <pre><code>// Registration form MCSS validation add_filter('gform_validation', 'custom_validation'); function custom_validation($validation_result) { $form = $validation_result["form"]; foreach($form['fields'] as &$field){ if(strpos($field['cssClass'], 'validate-mcss') === false) continue; $field_value = rgpost("input_{$field['id']}"); $is_valid = validate_mcss($field_value); if($is_valid) continue; $validation_result['is_valid'] = false; $field['failed_validation'] = true; $field['validation_message'] = 'The MCSS you have entered is not valid.'; } // update the form in the validation result with the form object you modified $validation_result["form"] = $form; return $validation_result; } function validate_mcss($mcss) { // check mcss value if ($mcss != "MCSS5") { // MCSS is not valid - must match MCSS5 return false; } }</code></pre> Alex Cancado on "Gform_validation example" https://legacy.forums.gravityhelp.com/topic/gform_validation-example#post-28483 Fri, 24 Jun 2011 11:17:10 +0000 Alex Cancado 28483@https://legacy.forums.gravityhelp.com/ Thanks for the better example! I have replaced our existing example with yours (with a minor change to make it even more useful). As far as setting the main message, you can use the gform_validation_message filter to change it. <a href="http://www.gravityhelp.com/documentation/page/Gform_validation_message" rel="nofollow">http://www.gravityhelp.com/documentation/page/Gform_validation_message</a>. I agree it would be nicer to set it right from the gform_validation hook. I will keep that in mind for the next versions. bristweb on "Gform_validation example" https://legacy.forums.gravityhelp.com/topic/gform_validation-example#post-28456 Fri, 24 Jun 2011 00:20:34 +0000 bristweb 28456@https://legacy.forums.gravityhelp.com/ one other thought. it would be nice if you could override the text "There was a problem with your submission. Errors have been highlighted below." and replace / append with your own custom message. some validation will not be related to a specific field... bristweb on "Gform_validation example" https://legacy.forums.gravityhelp.com/topic/gform_validation-example#post-28455 Fri, 24 Jun 2011 00:18:07 +0000 bristweb 28455@https://legacy.forums.gravityhelp.com/ <a href="http://www.gravityhelp.com/documentation/page/Gform_validation" rel="nofollow">http://www.gravityhelp.com/documentation/page/Gform_validation</a> the example code you offer here is a little confusing <pre><code><?php add_filter('gform_validation', 'custom_validation'); function custom_validation($validation_result){ // set the form validation to false $validation_result["is_valid"] = false; $form = $validation_result["form"]; // specify the first field to be invalid and provide custom validation message $form["fields"][0]["failed_validation"] = true; $form["fields"][0]["validation_message"] = "This field is invalid!"; // update the form in the validation result with the form object you modified $validation_result["form"] = $form; return $validation_result; } ?></code></pre> your example would override all other validations and only perform the one validation example you give. the following would be a better example <pre><code><?php add_filter('gform_validation', 'custom_validation'); function custom_validation($validation_result){ if($_POST['input_1'] == 86){ //supposing we don't want input 1 to be a value of 86 // set the form validation to false $validation_result["is_valid"] = false; $validation_result["form"]["fields"][0]["failed_validation"] = true; $validation_result["form"]["fields"][0]["validation_message"] = "This field is invalid!"; } return $validation_result; } ?></code></pre>
