I'm trying to show or hide a button based on if a user has permission to post content to a group or not, but I don't seem to be able to call the
og_user_access function from my custom module.
I've tried calling it directly while loading the module file:
$allowed = og_user_access('group', $group->nid, 'create resource content');
Doing this crashes the page with no Apache error just a watchdog error of:
Error: Class name must be a valid object or a string in entity_get_controller() (line 8066 of /data/home/rsdev/www/content/lnsres.rsdev.ca/web/includes/common.inc).
I've also tried using
module_invoke like so:
$allowed = module_invoke('og', 'og_user_access', 'group', $group->nid, 'create resource content');
Calling the module like this doesn't crash the page, but it also doesn't return anything and if I add some
dpm() calls in the contrib module function I notice it's not even being called. Doing some reading about
module_invoke appears like it's mostly used to call hooks, which I don't think
og_user_access is, so I'm not sure if that's even the correct path to take.
How should I check group permissions in OG from my custom module's code ?
EDIT: This is not a duplicate of Display data basing on the group permission
because I'm not trying to use a permission I created. Also the only answer in that question doesn't work for me because as I explained, I can't call
og_user_access without an error.
