PHP: Parsing of a given form input variable

How would I go about parsing incoming form data where the name changes based on section of site like:

<input type="radio" name="Motorola section" value="Ask a question">

where 'Motorola section may be that, or Verizon section, or Blackberry section, etc.

I do not have any control over changing the existing forms unfortunately, so must find a way to work with what is there.

Basically, I need to be able to grab both the name="" data as well as its coresponding value="" data to be able to populate the email that gets sent properly.

Well, first off, you shouldn't have spaces in the name field (even though it should work with them).

Assuming it's a form, you can get the value through the $_POST (for the POST method) and $_GET (for the GET method) variables.

<?php
if ( isset( $_POST['Motorola section'] ) ) // checks if it's set
{
   $motoSec = $_POST['Motorola section'];  // grab the variable
   echo $motoSec; // display it
}
?>

You can also check the variables using print_r( $_GET ) or print_r( $_POST ).

Well, you don't receive a HTML form, but just field names and values in $_POST. So you have to look what to make out of that.

Get the known and fixed fields from $_POST and unset() those you've got [to simplify]. Then iterate over the rest. If " section" is the only constant, then watch out for that:

foreach ($_POST as $key=>$value) {
    if (stristr($key, "section")) {
        $section = $value;
        $section_name = $key;
    }
}

If there are multiple sections (you didn't say), then build an section=>value array instead.
