Re: Re: isset

It's common mistake what you are doing... the first thing should be to test if there is such key in array: if (array_key_exists('cmd',$_POST)) { } this means to test it the variable exists, then you can test if it was set Brona Chris W. Parker wrote:

seems lengthy. is there a way around this? i tried using $cmd = @ $_POST['cmd']; to suppress errors but didnt seem to have ay effect.

still if(isset($_POST['cmd'])) { $cmd = $_POST['cmd']; } is the only (really) correct way. All others throw notices of undefined indices, which you *should not* ignore! You can't shorten it, you can't even wrap it in a function... it's simply tough luck

Please correct me if I'm wrong (and maybe this is what you mean by "(really)") but I think even Rasmus recommends: <?php if(!empty($_POST['cmd'])) {

    // stuff

} ?> I'm using the following code to test this: <?php

    error_reporting(E_ALL);

    if(!empty($_POST['cmd']))
    {
        echo "set and not empty<br />";
    }
    else
    {
        echo "empty and/or not set<br />";
    }

?> Chris.
