Getting post data in plugin

Ive been messing around with making plugins, but I’m not primarily a php programmer. I’m trying to get the form data from the plugin-editor.php page in the plugin itself:


add_action('init', 'one');
add_action('admin_head', 'two');

$formField = "";

function one()
{
global $formField;
$formField .= $_POST['file'];
//echo "one:" . $formField;
}

function two()
{
global $formField;
echo "two:". $formField;
}

If I echo out the $formField variable in the first function (init) then it has the correct field value. But How can I then assign that value to a variable that is accessible when I get to the second function (admin_head).

If I do echo $_POST[‘file’] in the admin_head it returns no value.

Thanks,
