Cannot delete individual input fields

Thanks for all the research. It does look like a bug. I will try to replicate it here again and let you know if I find anything

I was able to replicate the issue and created an updated version that solves the issue. We will release that version to the public soon, but if you would like to get it now, please fill out the contact us form on this site and we will forward it to you.

@edtv82 The form appears to be working fine when I browse it. Are you having an issue with the frontend form or with the admin? Because this thread was related to an unrelated issue.

@tonyallsopp Have you tried deactivating your theme and using the default Twenty Ten theme? If not, you also need to do that. Make sure you have followed all the instructions found here:

There is no work around for bad code caused by a theme developer not knowing what they are doing other than to fix the code.

What is likely happening is the Theme is outputting code on every single page and not isolating it's code output to just when necessary. So that theme is outputting code everywhere, including our Form Editor page.

This is the primary cause of theme/plugin conflicts, when theme developers don't use best practices. The way PHP and WordPress plugins and themes work, there is no way for us to prevent this from happening because we can't control what other themes and plugins output.

@defkaltion The issues in this thread are related to themes or plugins interfering with the form editor. They aren't due to a problem in Gravity Forms. We have absolutely NO control over what other plugins you install do or what your theme does. There is no way to "block" the "bad theme" output. It simply isn't possible. It's not how WordPress development works.

Gravity Forms works with themes built with best practices. If a theme or plugin is built using best practices it won't interfere with Gravity Forms. There are thousands of WordPress themes in existent, we simply can't guarantee a theme won't cause a problem because we didn't create the theme and we can't guarantee your theme was built using best practices. Most of the major theme developers build their themes using best practices and these issues simply don't happen.

We outline a way to determine what the issue is above. You have to test for theme and plugin conflicts. OR if you know how to debug Javascript you can use something like Firebug to see what Javascript errors are on the page and debug where the error is coming from. Most of our users aren't this savvy so simply activating and deactivating plugins and themes is the easiest way to narrow down the problem.

Blaming us for bad code in someone else's theme or plugin breaking Gravity Forms is counter intuitive, you should be more concerned with why your site has bad code and be interested in determining what code is bad and how to fix it.

@defkalion Gravity Forms is not compatible with themes that were not built using best practices. We shouldn't have to state on our site that Gravity Forms doesn't work with broken themes. Themes not built with best practices are broken. You just don't know it until an issue like this arises.

Your theme is outputting javascript on the Gravity Forms admin page which it should not be doing because it was not built with best practices. That is the problem.

You have two options to resolve this issue.

Since you are unable to activate a different theme to test for conflicts, we can take a look at the form editor and tell you the exact reason why the issue is happening. What is causing the Javascript error. Then the theme can be corrected. It's usually something simple.

Or we can simply give you a refund and ultimately your theme will still have this issue which isn't exactly ideal.

You aren't wasting our time. We are fine either way, we just ask if you go the support route that you work with us rather than against us. We are here to help our users, not fight them.

@defkalion Unfortunately there is no visible Javascript error message on the form editor for us to debug. It's not a plugin conflict because it happens with only Gravity Forms activated. So it's either an issue introduced by your theme, or a server issue we've never seen before.

Something is preventing the delete action from executing. As you can see from above the only users that have experienced this issue it was theme related. So if it's server related it would be something we haven't seen before.

Since you can't deactivate your theme, what we will need to do is send me a copy of your theme zip file so we can test locally. So we can limit the amount of back and forth if you can simply send me an FTP login for this site that would be more ideal. Then we can simply get the theme from your server and test locally, if we can't reproduce it locally we can then debug the code directly on your server to see why it's not deleting.

You can send me the FTP information directly at carl@rocketgenius.com and we can take a look and see what the issue is.

@defkalion Your problem is indeed related to your theme. It was trying to delete a file if a variable named "field_id" was submitted in the post.

The problem is that functions.php runs in every request, so any plugin that submits a variable named "field_id" (which is the case with Gravity Forms) will trigger this logic and the theme will try to delete a file and fail (because the file doesn't exist).

To fix it, the theme will have to make sure the request is actually coming from the theme's setting page.

We replaced the original line:
if(isset($_POST['field_id']) && !empty($_POST['field_id']))

With the following:
if(isset($_POST['field_id']) && !empty($_POST['field_id']) && isset($_GET["page"]) && $_GET["page"] == "functions.php" )

We made the change to your theme on your server so you should be good to go.

You may want to make whoever made your theme aware of this issue and what the fix is.
