I've sent you the code. </p> https://legacy.forums.gravityhelp.com/topic/gform_validation-using-php-class#post-124447 Thu, 17 Jan 2013 12:06:32 +0000 Alex Cancado 124447@https://legacy.forums.gravityhelp.com/ <p>Your code looks right and the filter should fire. The only question is where you are placing it. The $this variable is only defined inside your class, so you need to make sure that line of code is being called inside one of your class' methods.<br /> I will be glad to take a look at your file if you send it to <a href="mailto:alex@rocketgenius.com">alex@rocketgenius.com</a> (please include a link to this post) </p> https://legacy.forums.gravityhelp.com/topic/gform_validation-using-php-class#post-124381 Thu, 17 Jan 2013 10:11:58 +0000 burfield 124381@https://legacy.forums.gravityhelp.com/ <p>In addition it's worth mentioning that the only reason I was trying to apply custom validation is because the dropdown field I marked as "required" in the GF admin area was not being picked up as invalid during form submission.</p> <p>The process was:</p> <p>1) Form is rendered and dropdown A is populated with values form a Custom Post Type.<br /> 2) When the user selects from dropdown A, some javascript runs which populates dropdown B with the correct values (these are from another post type).<br /> 3) When the form is submitted with the default value (eg: "Please select") Gravity forms allows the form to be submitted even though it should fail validation due to no value being selected.</p> <p>I've now resolved the issue which lies in the GF's admin interface for Form creation. The issue was that by default even though I'd removed all but 1 value for the dropdown B, GF's was setting a "value" attribute on the option element. This caused it to pass validation as there was always value selected. </p> <p>To solve this, in the form builder admin area you must select "Show values" on the "Choices" field and then ensure that the contents of the "Value" field is entirely blank. I feel this should be made more obvious.</p> <p>So in essence my issue is solved in the short term. Nonetheless I would appreciate feedback from your developers on how I might be able to add_filter using a Class method. </p> https://legacy.forums.gravityhelp.com/topic/gform_validation-using-php-class#post-124367 Thu, 17 Jan 2013 09:42:51 +0000 burfield 124367@https://legacy.forums.gravityhelp.com/ <p>Great stuff. Happy to send website code to a private email but not able to post on forum.</p> <p>If it helps the <code>gform_pre_render_7</code> filter seems to work perfectly using the same method:</p> <p><code>add_filter(&#39;gform_pre_render_7&#39;, array( $this, &#39;populate_select_fields&#39; ) );</code></p> <p>The <code>apply_filters</code> call in form_display.php seems quite complex. Maybe this is where is issue lies...? Maybe it's my code?</p> <p>Help is appreciated. </p> https://legacy.forums.gravityhelp.com/topic/gform_validation-using-php-class#post-124313 Thu, 17 Jan 2013 08:09:47 +0000 Chris Hajer 124313@https://legacy.forums.gravityhelp.com/ <p>I'll bring this to the attention of the development team for their input. I've never seen anyone try to use gform_validation like this. </p> https://legacy.forums.gravityhelp.com/topic/gform_validation-using-php-class#post-124296 Thu, 17 Jan 2013 07:54:32 +0000 burfield 124296@https://legacy.forums.gravityhelp.com/ <p>Hi,</p> <p>My form has ID "7". I'm trying to fire a custom validation on submit but the validation function doesn't appear to be running.</p> <p>I believe this might be to do with the fact that I'm working with a PHP Class which means I'm doing the following</p> <p><code>add_filter(&#39;gform_validation_7&#39;, array( $this, &#39;validate_me&#39; ) );</code></p> <p>rather than simply...</p> <p><code>add_filter(&#39;gform_validation_7&#39;, &#39;validate_me&#39; );</code></p> <p>The validate me method does not get called when I submit my form. I know this because I've placed</p> <p><code>exit()</code> </p> <p>within the body of that method. No dice.</p> <p>Any help much appreciated. </p>
