Grabbing everything from a form

netfrugal

this may seem like a dumb question.

I know I can grab a field by simply using $_POST'field']

Is there a way to catch everything at once? I want to see if I'm missing any fields that are being passed to me, but I'm not grabbing.

Hope I make sense!

Use [man]foreach/man on the $_POST array.

Ok, this may sound even dumber. As I'm looking at the php.net manual on foreach(),

I'm not sure how to use it.

I'm attempting to just place in alone on a page that the external form is posting to.

This is what I'm sort of getting from some other post:

foreach($_POST[ as $key=>$value){ $$key=$value; }

Will foreach() simply show all _POST variables in an array?

Erm... I think you have your terms mixed up.

The variable $POST is an array. When you submit elements in a form (let's exclude arrays, such as checkboxes, multiple SELECT elements, etc. etc.), the $POST array is populated with the submitted data. The name of the submitted element is used as the key and the submitted value is used as the value (of course).

So, if you wanted to output all elements in the $_POST array, you could do:

foreach($_POST as $key => $value)
    echo $key . ' has a value of: ' . $value . "<br>\n";
