error processing.. no luck :(

[dv6cougar]

here's my short function:

$messages = array();
function displayError($messages) {
			echo "<b>Your action created an error(s) on the page</b><br /><br />";
			echo "Your error(is) is/are:<br />";
			echo "<ul>";
			foreach($messages as $msg) {
			echo "<li>$msg</li>\n
			";
			}
			echo "</ul>";
			}

then when I have an error I do...

$messages[] = "Error message";

and then i have:

//this was after i had tried ($messages) which i think 
//should have worked
if($messages !== "") {

	displayError($messages);
	exit;
	}

i have set global $messages; as well, and it doesnt' show my messages 🙁

it shows the rest of it though. What am I possible doing wrong? 🙁

let me know what you think. I'm thinking that my global $messages; isn't working properly, but I've used global alot before and I've never had a problem

thanks all 🙂

You shouldn't need global $messages as you are passing it to the function

I ran this (copied and unchanged from you post, except I added 2nd error message) and it works OK

$messages = array();
function displayError($messages) {
            echo "<b>Your action created an error(s) on the page</b><br /><br />";
            echo "Your error(is) is/are:<br />";
            echo "<ul>";
            foreach($messages as $msg) {
            echo "<li>$msg</li>\n
            ";
            }
            echo "</ul>";
            }
$messages[] = "Error message 1";
$messages[] = "Error message 2";

if($messages !== "") {

    displayError($messages);
    exit;
    }

Well you're not actually using $messages as a global.

Also I'd try:

if(count($messages) != 0) {
displayError($messages);
exit;
}
