Getting all vars from post

[mrhinman]

I'm sure I've seen this before, but forget how to do it. Isn't there a way to get the values of all the fields in a posted form from one line? I have a form that has some 300+ variables and I'd like to just check them all at once to see if there are any zeroes in any blank.

You can loop through the $REQUEST (or more specifically, $POST) array.

Well, how would I do that withtout having to re-type all 300+ variables? An example would be helpful.

My current post processing says to "INSERT INTO / UPDATE table SET var1='$var1', var2='$var2'.... etc"

I have that for all the variables, but I want to run through all posted variables to check for a single "0" and replace with "" before inserting or updating.

How about this...

foreach ( $_POST as $key => $value ) {
    if ($value == 0) {
        $_POST[$key] = '';
    }
}

That should replace all the zeroes with empty strings in your $_POST array.
