Re: Other Notice problem...

The array_key_exists or isset is a good solution. About your comment, i have the register_globals=on. I have 2 questions: 1.- What's the relation to have register_globals=off with this notice message? 2.- I read the security comment about register_globals=on in the php.ini, but i set to on because if i set to off, i can't pass GET variables to other page. how can you pass GET variables to other page without setting register_globals=on?

I have an php page (addProduct.php) with an input form. I have 2 buttons (add and cancel) and a hidden control with name=status. If i press the add button, the page submit the form data to the same page (<form action="addProduct.php">) with status hidden control name set to ADD, so the if statement its true only if i press the add button. I see the message when i call the page to add the data not when i submit the data. --------------------[snip]-------------------- Ahhh.... your $status variable should be a form variable? Well, as pointed out many times the last days, register_globals is OFF by default since PHP v.4.something. Either turn register_globals on in your PHP.ini (bad and deprecated, read the security bulletins), or you refer to the _POST array:

    if ($_POST['status'] == "ADD")

if the data is not set (the status control empty), you'll still get a notice about an undefined array index, so you might

    if (array_key_exists('status', $_POST)) {
        switch ($_POST['status']) {
        case 'ADD':
            break;
        default:
            echo 'Unsupported status!';
        }
    }
    else echo 'No status sent!';
