Simple PHP Function to Maintain Drop-Down State

This PHP function is a quick, simple way to maintain the state of select / drop downs when the form input is invalid.

/** * Function to draw drop down boxes and allow the state to be maintained * if the form has an error * * @param array $vals - select box values * @param array $text - select box show values * @param string $search - the name/id of the select box to be searched for */ function dropDown( $vals, $text, $search ) { for ($i=0; $i < count($vals); $i++) { if ($search == trim($vals[$i])) { $selected = "selected=\"selected\""; } else { $selected = ""; } $result .= "$text[$i]\n"; } return ($result); } ?>
