Invalid argument errors

It looks like I messed up when I was tagging my 5.0 release. I gave it another go and it should be ready. This release should address the issue that you're having. You can grab the latest 5.0 code here:

http://cvs.drupal.org/viewcvs/drupal/contributions/modules/cck_field_per...

Where you say:

Also there is nothing listed below "Field permisions:" in any of my 'fields' groups under that admin page.

You won't get any fields listed if there aren't any cck fields defined for this content type.

thanks for the feedback.

Hi Arthur,

I'm afraid this error still occurs in the new release. I think this is due to not having defined any CCK fields to have permissions set. If I add a field to the blog content type, and DON'T enable any CCK-added fields to have permissions set on them (see attached picture), I get the exact same error on all my content pages.

It's clear it is unlikely that one would enable a content type to have permissions set on it, and then not set any fields as such, but the situation exists nonetheless. I believe the solution to this would be simply to add a check to see if any fields have been selected before attempting to access the array here:

On the next line (I have experienced this in only two places thus far) after this unserialize, the code attempts to access the contents of the $disallowed_fields array, but there is no check to see if it is empty AFAIK, which I assume causes the error.

Forgot to change version number, sorry.

I updated the 5.0 branch for this. Let me know if that works for you.

Job done, can't generate any errors now. At least, not the old way... :)

Hi-

Please update to the latest release- the issue you're reporting should be resolved.

thanks

I'm getting this same error in the 4.7 version. I'll continue troubleshooting to see if I can find out more. Should the 4.7 issue be in a different thread?

On your question - not sure. You might be able to take a diff of your 4.7 and latest 5.x code and spot the problem from that though? Depending on your php experience and knowledge of Drupal, presumably... :)

Me too I'm getting the same error:

warning: Invalid argument supplied for foreach() in E:\webroot\yth3\modules\cck_field_perms\cck_field_perms.module on line 82.

module version: 1.3.2.27 (2007/08/27 21:25:36 arthuregg)
Drupal version: 5.5

I started to get this error once I removed node-profile module and reinstalled and activated it. I don't know if it can have anything to do with the error.

Hi,

I am getting this error as described above, it appears on the home page in the lovely red error box...

warning: Invalid argument supplied for foreach() in ... /modules/cck_field_perms/cck_field_perms.module on line 77.

I have found the cause and it is when I have activated Field permissions for a content type which does not have any CCK fields created for it.

Could a check be implemented to remove the error?
I would try to help out with a patch but the code is beyond me at this point.

Thanks

Richard

Good catch. Indeed we should be able to prevent any new cck_field_permission by enabling any content type susceptible to host such a field.

Getting it on line 182 now...

Same error for me on line 182 in version 5.x-1.10 on Drupal 5.1 :(

Same here for a content type with no fields.
(I enabled it for CCK field perms and was going to add the fields later...)

Line 182 is:

Casting $disallowed_fields[$type] to an array would work, as would checking it's non-empty.

The easy solution to this problem would be to change lines 76 and 179 from
if ($disallowed_fields) {
to
if (is_array($disallowed_fields)) {
