And others to change the HTML.</p> <p>Thanks for your help. </p> https://legacy.forums.gravityhelp.com/topic/valid-some-special-characters-for-emails#post-11029 Mon, 11 Oct 2010 17:48:29 +0000 Carl Hancock 11029@https://legacy.forums.gravityhelp.com/ <p>Yes, if that is what you need to change the only way to change it would be to change the core plugin code in common.php as their is currently no hook for that. But we can look into adding a hook in the next release. </p> https://legacy.forums.gravityhelp.com/topic/valid-some-special-characters-for-emails#post-11026 Mon, 11 Oct 2010 17:14:15 +0000 victor 11026@https://legacy.forums.gravityhelp.com/ <p>Hi Carl,</p> <p>My email have an "ñ".

There is no filter on the is_valid_email that I am aware of and i'm not sure why you would need to change backend notification functionality. </p> https://legacy.forums.gravityhelp.com/topic/valid-some-special-characters-for-emails#post-11015 Mon, 11 Oct 2010 13:53:19 +0000 victor 11015@https://legacy.forums.gravityhelp.com/ <p>Hi Carl,</p> <p>I need to change it for backend and frontend.</p> <p>The function to add a filter is "is_valid_email" on common.php.

This is an advanced customization and in your case you would need to write a custom REGEX expression to validate what you want to do.</p> <p>I can't write the customization for you as it is a customization but the gform_validation filter looks like this, keep in mind this example:</p> <pre><code>&lt;?php add_filter(&#39;gform_validation&#39;, &#39;custom_validation&#39;); function custom_validation($validation_result){ // set the form validation to false $validation_result[&quot;is_valid&quot;] = false; $form = $validation_result[&quot;form&quot;]; // specify the first field to be invalid and provide custom validation message $form[&quot;fields&quot;][0][&quot;failed_validation&quot;] = true; $form[&quot;fields&quot;][0][&quot;validation_message&quot;] = &quot;This field is invalid!&quot;; // update the form in the validation result with the form object you modified $validation_result[&quot;form&quot;] = $form; return $validation_result; } ?&gt;</code></pre> <p>If you need assistance writing this customization I can refer you to a WordPress consultant with Gravity Forms development experience who could work with you on this. </p> https://legacy.forums.gravityhelp.com/topic/valid-some-special-characters-for-emails#post-10982 Sun, 10 Oct 2010 13:06:59 +0000 victor 10982@https://legacy.forums.gravityhelp.com/ <p>Hi,<br /> I need to validate some special characters (ñ) for Notifications and Forms.<br /> How can I do it?<br /> Thanks </p>
