I don’t know if this is a bug or a user error or user confusion. I’m using a CAccessRule expression, which is supposed to be a string. If I use a string like “1==1” or “1==2” it works as expected. But I want to base the expression upon a “role” property I added to user, as in
[tt]Yii::app()->user->role == 'admin'[/tt]
If I put that in a string, it doesn't work. The manual says I can use $user instead of Yii::app()->user, but when I do that (in a string), I get "Undefined variable: user". However if I do this:
Sorry about that. I get the same response (undefined variable) whether I do:
[tt]'expression'=> $user == 'admin'[/tt]
or
[tt]'expression'=> "$user == 'admin'"[/tt]
And just to confirm, when the docs say it's a string, I assume that it's a string that gets eval'd, which is why 1==1 grants permission but 1==2 does not. Is that correct? Although in the usage of it that did work for me, it's evaluating immediately and assigning a boolean to expression.
Okay, now I have no idea what I did wrong previously, because the code I just posted wasn't correct, obviously, but the code you recommended did work. Clearly my mistake somewhere.
Big thanks for your help and for the Yii Framework!
When you use 'expression'=> $user == 'admin', the expression actually gets the value of $user == 'admin'. And when you use 'expression'=> "$user == 'admin'", $user will be replaced with its value. In both cases, you should encounter a PHP error if $user is not defined.
