How do I use a GLOBALS or _SESSION field selection [message #659]

I am trying to validate the role of the user against a column in my table from the tasks "Selection (fixed)" field. Is this possible, or am I bound to static strings?

Thanks,

Dan

The "selection (fixed)" and "selection (temporary)" fields can only contain static strings. If you want to use the contents of any session or global variable you must do so in your code.

Thanks,

Now for the second problem, I edited the generated (list1).php for my app, and inserted the following

$sql_where = "source_key=$_SESSION['role_id']";

I also tried setting a local variable like:

$the_role = $_SESSION['role_id'];
$sql_where = "source_key='$the_role'";

The "source_key" is a column in my table used for both external references and enforcement of role access to specific rows. In both cases the role_id is blank. Is it not available inside the generated tasks?

Any help would be appreciated

There is no value in $_SESSION['role_id'] until AFTER the session_start() function has been issued, which is done within the initSession() function. This in turn is called within each of the page controllers, so no session variables can be accessed within a component script. You will have to use one of the custom methods within your database table class, such as _cm_pre_getData().

Thank you Tony,

With what you told me, and what I saw in a previous post, I was able to get my role_id to work correctly.

Again, thanks for all the help!
