I found an error, but it didn't do me any good.
I tried this, any tips...

function assign() {
            global $adminurl, $string;
            if ($string) {
                    $data = explode ("|", $string);
                    foreach ($data as $foo) {
                        echo $foo[0]; }

        $array = array("$new_cat","$assigned_to","$job","$assigned_by");
        $string = implode("|",$array);
          return  $string;

The variables that form $array are from the form....
