function and variable problem

oops73

I thinks i have been infront of the compter for too long now...
Can anyone help me out here.

I have a functionpage and a "client page"

The function i have problem with is this:

///// Check if empty fields /////
function checkfields($value) {
    $array = array('Fname', 'Lname', 'IDcode', 'Region', 'Depart', 'Email'); 
    foreach ($array as $value) { 
    if(empty($$value)) { 
        return TRUE;
    } else {
	    return FALSE;		 
  }
 }
}

And the "client page":

 //// Check If Empty //// 
    if (checkfields($value) == FALSE) {
	$error['value'] = "Please check your fields.!";
	} else {

I get this error message from the browser:

"Notice: Undefined variable: value in c:" this error is on the "client page"

Help....

Depending on the other code which I am not privy to, you could have more than one problem, but in the code you've provided there is a definite problem and that problem is variable scope.

The problem is that in the checkfields function, you are checking if $Fname, $Lname, etc are empty, which obviously they are because you just created them inside the function.

I assume you were intending to check variables which were submitted by a form. If that's the case, you can save yourself trouble by checking the $POST superglobal for the variables (superglobals such as $GET and $_POST are global and are not subject to variable scope).

Check out the variable scope link I put above so you understand how scope works and then life will be much better for you. 🙂
