[RESOLVED] three conjoined tests in php conditional fails?

[aplacito]

Perhaps I'm just crazy this morning, but it seems that one cannot use three tests joined with && in a php conditional. For example, the following code works:

$errors = 0;
if ($submitted) {
     if(($_POST['un'] != "") && ($_POST['pw'] != "")) {
             $errors = 2;
     }
}
//when $submitted is true, $errors is 2,
//when $submitted is false, $errors is 0.

but the following doesn't work properly:

$errors = 0;
if ($submitted && ($_POST['un'] != "") && ($_POST['pw'] != "")) {
     $errors = 2;
}
//when $submitted is true, $errors is 2,
//when $submitted is false, $errors is 2.

am I missing something completely? can anyone confirm or refute this oddity?

I suspect the problem is elsewhere, either in logic or perhaps a typo in variable names or such. The following works fine for me, copying and pasting your if block:

<?php
$errors = 0;
$submitted = false;
if ($submitted && ($_POST['un'] != "") && ($_POST['pw'] != "")) {
     $errors = 2;
}
echo $errors; // outputs "0"
