Question

So I’ve got this code and part of it is a form, and ALL fields are absolutely required.

I just can’t find clear documentation for my needs to validate everything.

would I do something like this?

$foo = $_POST['foo'];
$bar = $_POST['bar'];
$lorem = $_POST['lorem'];
$ipsum = $_POST['ipsum'];

$isSet = array($foo, $bar, $lorem, $ipsum);

if(isset($isSet)) { /* Do the stuff */ }

or is there a better way? I don’t really want to do

if(isset($foo) && isset($bar) && isset($lorem)........ 

because i’ve got about 12 fields that are required

Answer 1

You can do:

if (isset($foo, $bar, $lorem, $ipsum)) {.....}

Saves you one step.
