I put in a feature request here <a href="http://www.gravityhelp.com/forums/topic/simple-custom-validation" rel="nofollow">http://www.gravityhelp.com/forums/topic/simple-custom-validation</a> to request this process be simpler. I also have a quick question with custom validation like <code>$form[&quot;fields&quot;][4][&quot;failed_validation&quot;] = true;</code> where does the <code>[4]</code> come from? I know that's where the validation shows up but it seems to be independent from field number. From what I've gathered it's the position of the field starting with 0 so 4 would be the 3rd input field. Is this correct? </p> https://legacy.forums.gravityhelp.com/topic/custom-validate-name-dont-allow-numbers#post-22397 Mon, 04 Apr 2011 11:33:11 +0000 David Smith 22397@https://legacy.forums.gravityhelp.com/ <p>Hi Brooke,</p> <p>$_POST keys for radio, checkboxes, and advanced fields containing multiple inputs will follow this format:</p> <p>input_{field_id}_{input_index}</p> <p>So if the field's name is "input_2.3", this could be access in the $_POST like this: $_POST['input_2_3']. </p> https://legacy.forums.gravityhelp.com/topic/custom-validate-name-dont-allow-numbers#post-22361 Sun, 03 Apr 2011 22:29:44 +0000 BandonRandon 22361@https://legacy.forums.gravityhelp.com/ <p>Let's say I have a form and I am using <code>gform_validation</code> and the name advanced field(because I do) that is outputing </p> <pre><code>&lt;input type=&quot;text&quot; tabindex=&quot;1&quot; value=&quot;&quot; id=&quot;input_4_2.3&quot; name=&quot;input_2.3&quot;&gt; &lt;input type=&quot;text&quot; tabindex=&quot;2&quot; value=&quot;&quot; id=&quot;input_4_2.6&quot; name=&quot;input_2.6&quot;&gt;</code></pre> <p>With my other custom validation i'm able to use <code>$_POST[input_4_#];</code> but for some reason <code>$_POST[input_4_2.3];</code> dosen't work. </p> <p>Really all I want to do is not allow people to use numbers as their name. This should be a simple regex I just need to figure out how to get the Value of input 4_2.6 and 4_2.3. </p> <p>Thanks </p>
