Alex (from Gravity Forms) sent these instructions to me and they worked just fine.</p> <p>Following is a brief description on how to create a custom field type.</p> <p>1- Add your field type to the form editor toolbar using the following hook<br /> <a href="http://www.gravityhelp.com/documentation/page/Gform_add_field_buttons" rel="nofollow">http://www.gravityhelp.com/documentation/page/Gform_add_field_buttons</a></p> <p>2- Render your field on the form by using the following hook<br /> <a href="http://www.gravityhelp.com/documentation/page/Gform_field_input" rel="nofollow">http://www.gravityhelp.com/documentation/page/Gform_field_input</a></p> <p>3- Validate user entered input and return a validation error when appropriate, using the following hook<br /> <a href="http://www.gravityhelp.com/documentation/page/Gform_field_validation" rel="nofollow">http://www.gravityhelp.com/documentation/page/Gform_field_validation</a> (requires v. 1.6 which is still in beta)<br /> OR<br /> <a href="http://www.gravityhelp.com/documentation/page/Gform_validation" rel="nofollow">http://www.gravityhelp.com/documentation/page/Gform_validation</a></p> <p>4- If your field type requires special client side scripts, use the following hook to enqueue them<br /> <a href="http://www.gravityhelp.com/documentation/page/Gform_enqueue_scripts" rel="nofollow">http://www.gravityhelp.com/documentation/page/Gform_enqueue_scripts</a></p> <p>5- If your field type requires additional settings, you can add them using the following hooks<br /> Advanced Tab Settings<br /> <a href="http://www.gravityhelp.com/documentation/page/Gform_field_advanced_settings" rel="nofollow">http://www.gravityhelp.com/documentation/page/Gform_field_advanced_settings</a></p> <p>Standard Tab Settings<br /> <a href="http://www.gravityhelp.com/documentation/page/Gform_field_standard_settings" rel="nofollow">http://www.gravityhelp.com/documentation/page/Gform_field_standard_settings</a> </p> https://legacy.forums.gravityhelp.com/topic/custom-regex-validation-for-fields#post-39263 Fri, 28 Oct 2011 17:20:34 +0000 Contexture 39263@https://legacy.forums.gravityhelp.com/ <p>I've checked out the gform_add_field_buttons - it's not complex at all, it's outright incomplete. There doesn't appear to be any other hooks or documentation for *defining* the field you've just created a button for.</p> <p>The gform_add_field_buttons filter merely adds a button for a field that does nothing. If I had time to reverse engineer the plugin, I'm sure I could figure it out, but since I'm pressed for time, I find I'm better off just building forms by hand, the old fashioned way. </p> <p>It seems to me that Gravity Forms just isn't very flexible OR developer-friendly. </p> https://legacy.forums.gravityhelp.com/topic/custom-regex-validation-for-fields#post-39182 Thu, 27 Oct 2011 23:59:03 +0000 Chris Hajer 39182@https://legacy.forums.gravityhelp.com/ <p>You can do regex validation using the <a href="http://www.gravityhelp.com/documentation/page/Gform_validation" rel="nofollow">gform_validation</a> filter. The regex would go in your functions.php. If you mean via the form builder, that's something that has been discussed.</p> <p>You can create new custom field types using the <a href="http://www.gravityhelp.com/documentation/page/Gform_add_field_buttons" rel="nofollow">gform_add_field_buttons</a> filter. I wouldn't say it's non-complex, but it's certainly possible with Gravity Forms 1.5.3 or 1.6. </p> https://legacy.forums.gravityhelp.com/topic/custom-regex-validation-for-fields#post-39135 Thu, 27 Oct 2011 15:41:53 +0000 Contexture 39135@https://legacy.forums.gravityhelp.com/ <p>What I'd really, really, REALLY like to see is either of these two things:</p> <p>1) The ability to set a custom validation regex for any standard field OR<br /> 2) The ability to create new custom field types (which would allow "normal" people to reuse custom fields we create).</p> <p>I'm actually pretty amazed that Gravity Forms doesn't just do either of these things out of the box - not even in the latest RC. </p>
