Views Argument, PHP-Validation and CCK Userreference

By tfranz on 9 Jul 2009 at 22:03 UTC

I have a problem with the views argument PHP-Validation:

I want the PHP-Code be "TRUE" if the argument/USER-ID is the same as the value of the CCK-Field "Userreference" (I named it "field_privacy" in my examples).

(What i expect: every user should see all nodes which are marked by the Userreference with its name/uid. And later a bit more complex ...)

I have set up a Views-argument with "Content: Userreference".

In a Drupal-Block i have this working PHP-Code:

global $user;
if (arg(0) == 'node' && is_numeric(arg(1))) {$node = node_load(arg(1));}
if ($user->uid == $node->field_privacy[0]['uid']) {print '<p>TRUE</p>';} else {print '<p>FALSE</p>';};

If i paste this similar(?) code into the views-argument PHP-Validation it won't work any more:

global $user;
if (arg(0) == 'node' && is_numeric(arg(1))) {$node = node_load(arg(1));}
return $user->uid == $node->field_privacy[0]['uid'];

or with the User-ID als argument:
return $argument == $node->field_privacy[0]['uid'];

If i take a number/Uid, for example:
return $user->uid == 12;
or
return $argument == 12;
everything is working fine. Of course, "12" should be the value/uid of the nodes CCK-Field "Userreference" ...

(If i use the "Basic Validation" instead of the "PHP-Code", everything is working as expected ... so what's the similar PHP-Code to the Basic-Validation? I want a bit more complex validation later on ... )

What's wrong? How to get the value of the CCK-Field into my PHP-Code?

Thank you for any help!

You can do

You can do print_r($node->field_privacy[0]); to see the actual structure of the userreference field (i don't remember it off the top of my head).

Also-- be aware that this is not real access control. Whether or not nodes get listed in a view does not affect their 'viewability' anywhere else. That is, people will still be able to random browse nodes by entering their URLs directly into the browser (ie site.com/node/5, site.com/node/1000, etc).

Thank you for your reply! The

Thank you for your reply!
The following code is working in a block (showing me the Uid of the nodes userreference-field):

if (arg(0) == 'node' && is_numeric(arg(1))) {$node = node_load(arg(1));}
print '<p>'.$node->field_privacy[0]['uid'].'</p>';

So i expected $node->field_privacy[0]['uid'] to work in views, too ... but it seems it does not?!

(The real access control is another problem i solved already ... :-)

hmmm, maybe try:

global $user;
if (arg(0) == 'node' && is_numeric(arg(1))) {
  $node = node_load(arg(1));
  if ($user->uid == $node->field_privacy[0]['uid']) {
    return TRUE;
  } else {
    return FALSE;
  }
}

... no, it's not working

... no, it's not working either ... :-(

Can you paste your views export into the thread?
