using "userCheck" to validate new form variable

I'm trying to add to the "Function userCheck" a function to validate that a variable is not left empty. I tried adding this to the "if" list

Code:

   if ((!$locationid) || ($locationid=="")) $stop = "<center>"._LOCATIONERROR."</center><br>";

but it does not work. I added this line to my function too

Code:

    userCheck($locationid);

but still nothing. Anyone have a good easy way to do this?

Assuming you're using the same userCheck() function in Your_Account/index.php, it is set up for 2 arguments ($username, $user_email). So, when the function is called you call it using arguments that correspond to those values, by position. In other words, the first argument always refers to username. The second always refers to user_email, regardless of the values. Now, you need to add a place-holder for locationid. It doesn'nt matter what you name these place-holders. You could now have function userCheck($username, $user_email, $locationid) or you could have function userCheck($bob, $ted, $carol). The point is that , argA = value_of($bob), argB = value_of($ted), and argC = value_of($carol). So, assuming you are using something more like function userCheck($username, $user_email, $locationid), anytime you call userCheck, the third position is where $locationid must be passed. Something like userCheck($username, $user_email, $locationid);. So, your code of userCheck($locationid); will not work as the function will interpret that $locationid as $username. Clear?
