下面四个函数是自己亲自做的,注意红色的字,它们之间的关系就可以了

function custom_twenty_two_jses_menu()
{
   
    $items['batch_dhcps'] = array(
        'title' => '批量添加dhcp',
        'page callback' => 'custom_twenty_two_jses_batch_dhcps',

    );
    $items['network_segment_autocomplete'] = array(
        'title' => '批量添加dhcp',
        'page callback' => 'custom_twenty_two_jses_network_segment_autocomplete',
        'access arguments' => array('create wp_blog_clone_2 content'),
    );
    return $items;
}

function batch_dhcps_form()
{
    $form['dchp_network_segment'] = array(
        '#type' => 'textfield',
        '#title' => t('网段名称'),
        '#size' => 60,
        '#autocomplete_path' => 'network_segment_autocomplete',
    );
    $form['mac_address'] = array(
        '#type' => 'textarea',
        '#title' => t('mac address'),

        '#default_value' => $_SESSION['transfor_form_textarea'],
        '#description' => '一行一个mac地址中短横,冒号及连在一起的mac都可以;'
    );

    $form['submit'] = array('#type' => 'submit', '#value' => t('submit'));

    return $form;
}

function custom_twenty_two_jses_batch_dhcps()

}

    $string = _removeCnEnSpace($string);
    $results =  array();
      // 为什么drupal7 中后面没有fetchAll() 方法也行
    $results_db =  db_query("select n.nid,net_name.field_network_name_value,network_ip.field_network_ip_value,server_ip.field_dhcp_server_ip_value from node n
