如何在模块中创建自定义表单字段类型？

Question

我使用joomla 2.5,我想创建一个自定义表单字段类型 that stored in the same module.

在XML中:

 <fieldset  name="basic" addfieldpath="/modules/mod_royalslider/fields"></fields>
      <fieldset name="basic">
           <field name="title" type="City" label="anythging" description=""   />
      </fieldset>
 </fields>

在文件中 /modules/mod_royalslider/fields/city.php

<?php
// Check to ensure this file is included in Joomla!
defined('_JEXEC') or die('Restricted access');

jimport('joomla.form.formfield');

class JFormFieldCity extends JFormField {

    protected $type = 'City';

    // getLabel() left out

    public function getInput() {
            return '<select id="'.$this->id.'" name="'.$this->name.'">'.
                   '<option value="1" >New York</option>'.
                   '<option value="2" >Chicago</option>'.
                   '<option value="3" >San Francisco</option>'.
                   '</select>';
    }
}

现在它显示我的错误,当我删除 <fieldset name="basic" addfieldpath="/modules/mod_royalslider/fields"></fields>

错误消失,字段显示为文本字段.

你忘了指定型号的addfieldpath

<fields name="params">
   <fieldset name="basic" addfieldpath="/modules/mod_royalslider/models/fields">

       <field name="title" type="City" label="anythging" description=""   />

   </fieldset>
</fields>

只需将fields文件夹放在models文件夹中,然后像上面一样放置路径.
