Function problem

[Anon]

I'm sure there is something simple I'm overlooking, but can anyone please tell me why this does not work:

function terminate_check($cid,$terminate_q,$operator_val) {
global $terminate_result;
echo "terminate_q = $terminate_q<br>";
if($cid < $operator_val) {
if ($terminate_q != '0') {
// terminate response, but should not terminate immediately
$terminate_result = 'N';
$terminate_q = $terminate_q;
}
else {
// a terminate immediately response was given
$terminate_result = 'Y';
}
}
}

terminate_check('9','3','10');
echo "<br>terminate_result=$terminate_result | terminate_q = $terminate_q";

It echos the $terminate_result var correctly, but the $terminate_q var is empty. Thanks in advance for the help.

You aren't returning anything, James. Try this:

function terminate_check($cid,$terminate_q,$operator_val) {
global $terminate_result;
echo "terminate_q = $terminate_q<br>";
if($cid < $operator_val) {
if ($terminate_q != '0') {
// terminate response, but should not terminate immediately
$terminate_result = 'N';
$terminate_q = $terminate_q;
}
else {
// a terminate immediately response was given
$terminate_result = 'Y';
}
}
return($terminate_q);
}

$terminate_q = terminate_check('9','3','10'); echo "<br>terminate_result=$terminate_result | terminate_q = $terminate_q";

You don't seem to be actually returning anything. Having said that, try something like this:
...
// terminate response, but should not terminate immediately
$term_arr["terminate_result"] = 'N';
$term_arr["terminate_q"] = $terminate_q;
}
else {
// a terminate immediately response was given
$term_arr["terminate_result"] = 'Y';
$term_arr["terminate_q"] = $terminate_q;
}
}
return $term_arr;
}

and this:

echo "<br>terminate_result=$term_arr[terminate_result] | terminate_q = $term_arr[terminate_q]";

Ben, but he'll still not have $terminate_result... unless I'm missing something.

Ah, that did it. I just had to specfiy $term_array as global within the function, and the results were returned appropriately. Thank you very much!

Hmmm ... I think you may be missing something. It works because he has $terminate_result set as a global variable. You can't set $terminate_q as a global variable to get the same result because it is being fed from the function call - trust me, won't work. It would probably work if he set the variable before the function call and had it globalized ... does that make sense? No ... but it does in my head.

Oh yea, I see it now... kinda a wacky way to do it, either way, I'd pass the parameters using variables anyway...

On second thought, if $terminate_result changes in the function, his script won't see it unless he passes it back.
