[英]Joomla Component: View: Get values from field
我是Joomla的新手,尤其是組件開發。 無論如何,這是我的問題:
site \\ views \\ plaingallery \\ tmpl \\ default.xml
<?xml version="1.0" encoding="utf-8"?>
<metadata>
<layout title="COM_PLAINGALLERY_PLAINGALLERY_VIEW_DEFAULT_TITLE">
<message>
<![CDATA[COM_PLAINGALLERY_PLAINGALLERY_VIEW_DEFAULT_DESC]]>
</message>
</layout>
<fields name="request"
addfieldpath="/administrator/components/com_plaingallery/models/fields">
<fieldset name="request">
<field name="galleryFolder" type="folderlist" default="" recursive="true"
label="Select a folder" directory="images" filter="" exclude="" width="300"
hide_none="true" hide_default="true" stripext="" />
</fieldset>
</fields>
</metadata>
site \\ views \\ plaingallery \\ view.html.php
<?php
// No direct access to this file
defined('_JEXEC') or die('Restricted access');
// import Joomla view library
jimport('joomla.application.component.view');
/**
* HTML View class for the PlainGallery Component
*/
class PlainGalleryViewPlainGallery extends JViewLegacy
{
// Overwriting JView display method
function display($tpl = null)
{
// Assign data to the view
$this->msg = 'I am new to Joomla';
// Display the view
parent::display($tpl);
}
}
我的問題是:如何從菜單配置中提供的用戶從字段[name =“ galleryFolder”]中訪問值?
謝謝你的幫助! 我真的很感激。
此參數位於菜單項的查詢變量中。
您可以嘗試例如:
$app = JFactory::getApplication();
/* Default Page fallback*/
$active = $app->getMenu()->getActive();
if (NULL == $active) {
$active = $app->getMenu()->getDefault();
}
if ( isset($active->query['galleryFolder']) ) {
$galleryFolder = $active->query['galleryFolder'];
}
