Fatal error when hiding fields

Are you using any contributed modules which provide additional field types?

Can you provide the steps needed to reproduce this?

I am getting the same error too, but it happens when I try to click the field gear icon in the "manage display" form of my custom content type. I'm trying to configure an image field to be a "thumbnail" in teaser display, while the default is "original". The error is the same:

An AJAX HTTP error occurred.
HTTP Result Code: 200
Debugging information follows.
Path: /?q=system/ajax
StatusText: OK
ResponseText:
Fatal error: Function name must be a string in /home/(my domain)/public_html/modules/field_ui/field_ui.admin.inc on line 143

The error happens even if I try to drag field to hidden section, as for htalwala.
My content type has only the default "body" field and an "image" field.
I have installed other modules which provide fields ("term reference", "node reference"), but the error was there before. I changed the admin theme from Seven to Bartik but the error remains.

In my logs I find these two errors:

Error 1:

Error 2:

Thank you for any suggestion.

subscribe for now

update: my error has gone for the moment in the content type "manage display" page.

I do not remember the steps I took. I managed to move fields by toggling the "show/hide row weight" option at the top and moving by editing weights (the toggle hides the drag-n-drop handles, so I think the page disable ajax, but I'm not sure).

I disabled the Dhtml menu module, too, which I used to avoid page reload. I'm not sure this caused the issue because a similar error appears when I try to fill the autocomplete field of the state/province Location module.
(UPDATE: the error does not show any more in autocomplete Location module)

I'll let you know if I remember other steps I took.

Subscribe.

I'm getting the same error.

I try to change a content type and manage the display and I get this:

Error:

An AJAX HTTP error occurred.
HTTP Result Code: 200
Debugging information follows.
Path: /drupal7/system/ajax
StatusText: OK
ResponseText:
Fatal error: Function name must be a string in c:\wamp\www\drupal7\modules\field_ui\field_ui.admin.inc on line 143

I'm really not sure what I've changed, but everything had been working perfectly for some time.

I solved disabling the modele: Drupal for Firebug.

There seem to be lots of references to this problem, but I can't find a solution anywhere.

I have no clue what might happen here. It is probabaly caused by malformed "rows" in the form array describing the "Manage display" table. Off hand, I don't see how this could be related to the field_permissions module.

The attached debug patch should provide additional info to help us have a clearer notion about which module is at fault. To anyone facing the bug : please apply the patch and post the debug info here (might be reasonably large, please post in an attached .txt file).

Note : the patch will "hide" the bug but won't fix it. I don't recommend saving actual changes to your "Manage fields" forms with the patch applied.

Hi yched

First off - thanks very much for the reply.

I'm running on WAMP and don't have access to Linux / UNIX at the moment. You wouldn't happen to have a pre-patched version of the file you could share for Windows would you? I know what CYGWIN is, but I've never used it.

Also - how do you invoke the debug mode?

Thanks in advance.

Cheers

@jibberish: you can easily apply the patch manually. Edit the modules/field_ui/field_ui.admin.inc file, and within the field_ui_table_pre_render() function, delete the lines marked with a '-', add the lines marked with '+'.

@yched: I can manipulate image settings again now! Where do I find the log files? Is this in reports > Recent log messages

@yched: I'm going to assume that this is the location of the logs and there are 3 logs written each time I try to update an image:

Ok, so in your case this is caused by the captcha module. I'll investigate.

For others : please post the debug messages in an attached txt file ;-)

@yched

Thanks very much for the time you've put into this. You are absolutely right.

Test 1
Restore original field_ui.admin.inc and disable captcha
Result
All working

Test 2
Upgrage to captcha 7.x-1.0-alpha2 and enable captcha
Result
Fail

So - I had a little look around the Captcha options and found another test to try:

Test 3
Disabled "Add CAPTCHA administration links to forms" checkbox from withing configuration > captcha
Result
All working

I now have a fully working site. You are my hero!!!! Thanks very much!!!!

As a side note - I have a backup of the site with all the same modules but a with slightly older content types and content with that captcha option still on and everything works in there. If that hadn't been the case, I would've tried disabling captcha - but it worked on an old backup.

Thanks once again for helping me (and hopefully others) here....I really was starting to go a bit insane and lose all motivation.

Created #1121264: Breaks Field UI's "Manage display" page. in the Captcha issue queue.

Closing this thread as a duplicate.

If other people encouter the bug without having the captcha module enabled, please reopen and provide the debug info described in comment #11 above.

I can confirm a similar problem fixed by disabling "Drupal for Firebug."

In my case, I was trying to reveal hidden fields for the teaser display and received a fatal ajax error.

#17 worked for me
Disabled "Add CAPTCHA administration links to forms" checkbox from withing configuration > people > captcha > general settings.
thanks

This error also occurs with the module http://drupal.org/project/memcache installed on Drupal 7 (I am using Drupal 7.3-dev and memcache 7.x-).

It appears that memcache is not storing the form, or the forms token (?) and the $_POST data is empty, firing off the watchdog('ajax', 'Invalid form POST data.', array(), WATCHDOG_WARNING);.

The returned error is that ^^ above in watchdog. I opened an issue is the memcache module queue #1214536: Drupal 7 content-type fields_ui module ajax forms not getting cached

Hi laurent, i am having the same issues (same debug output) on drupal 7.17 since yesterday. Your directory structure suggests that you are using barracuda/octopus, is that right?

@laurent, if you are using barracuda/octopus: I just found out that there seem to be some cache related issues: Could you try to disable caching, through creating the file sites/all/modules/cache/NO.txt in your platform and check if the problem still appears? That did help in my case.

So since this is related to barracuda/octopus, not core's fault then, I'd suggest opening an issue in that project.

For reference: #1854926: field_ui error: Function name must be a string

In the BOA context it is a duplicate of #1839122: Disabling Redis on known AJAX calls breaks AJAX based UI elements
