phpHtmllib: Automatically generate form from database tables

Just experimenting, inspired by rubyonrails.

class gemilang_standardform_auto extends gemilang_standardform {
    var $_my_elements = array();
    var $_my_tablename;
 
    function setup_auto_init_elements() {
        $db = &$GLOBALS['db'];
        $rs = $db->Execute("select * from $this->_my_tablename limit 1");
        while (!$rs->EOF) {
            $fld = array();
            while ($count < $rs->_numOfFields) {
                $fld[] = $rs->FetchField($count);
                $count++;
            }
        $rs->MoveNext();
        }
 
        $this->my_elements = array();
        foreach ($fld as $field) {
            $attr = array();
            $attr['name'] = $field->name;
            $attr['type'] = $field->type;
            $attr['length'] = $field->max_length;
            if (!isset($this->_my_elements[$field->name]['control'])) {
                $attr['control'] = 'text';
            } else {
