Simple API Question

Thanks that's a real help. With respect to 'my_module', which module is that? For a content type, would that be 'node'?

OK I've actually got my head around this now and it works. The only problem I'm still having is with respect to permissions - when the PHP is run by an admin it works fine, but when it is run by a normal authenticated user, it has no effect.

What do you think I've missed?

Thanks,
Chris.

OK, what I've done is a bit of hack. I've stuck this code into part of a CCK computed field's PHP, which means that it executes 'on submit' of a content type.

$acl_id=acl_get_id_by_name('content_access',"view_$nid");
acl_add_user($acl_id, $job_poster);

I've been using the content access module elsewhere on the site, which is how I learnt about ACL. I adopted a similar syntax to the code I found in the content access module, which lead me to the code above. It performs the exact task I'm looking for when logged in as admin, but sadly won't work if I'm logged in as a normal user.

What do you suppose might be the problem? I'm guessing it's with the use of the 'content_access' module, or does this field not really matter...?

Thanks for all your help!

OK. I've enabled DNA and it's very useful. I've adjusted the module to be something else, not 'content_access'.

Though I can clearly see what grants have taken place (and confirm this looking at the ACL tables in the database), it still refuses to actually perform the grants unless admin is logged - suggesting there maybe be a permissions issue. Clearly there is no 'access control' section for ACL, and the devel tools don't reveal what happens 'on submit' (including the query logger). Any other ideas what might be bottlenecking the grant?

Thanks again!
Chris.

Sorry I meant 'logged in'.

Despite running the code specified, the DNA output is as follows:

node_access entries for nodes shown on this pagenode realm gid view update delete explained
Job Application content_access_author 10 1 0 0 Content access: author of the content can access

In other words, the code I pasted previously works correctly, but it only works if logged in as admin. It doesn't work for normal users.

I've modified the code now to be the following, based on a re-read of the ACL module code:

if($job_poster!=0){
$acl_id=acl_get_id_by_name('content_access',"view_$nid");
if(!$acl_id)
$acl_id=acl_create_new_acl('content_access',"view_$nid");
acl_add_user($acl_id, $job_poster);
acl_node_add_acl($nid,$acl_id,1,0,0,0);

This appears to do the trick. I have reverted back the module to 'content_access'. I noted your warning with respect to this causing problems, however it did not work when using any other name.

Thanks for all your help!
