在后端,您将选择文章,文章的ID将存储在组件参数(config.xml)或自定义组件参数表中的数据库中。

在您的自定义组件

  1. 将文章ID存储为变量
  2. 使用文章ID
  3. 查询数据库#__content
  4. 显示文章
  5. 例如

     //
     // Function for your model
     //
    /**
     *
     * @return object 
     * 
     * Object will have following structure 
     * 
     * Field            Type    
     * ----------------------------------        
     * id               "int(11) unsigned"
     * title            varchar(255)
     * alias            varchar(255)
     * title_alias    varchar(255)
     * introtext        mediumtext
     * fulltext         mediumtext
     * state            tinyint(3)
     * sectionid        "int(11) unsigned"
     * mask             "int(11) unsigned"
     * catid            "int(11) unsigned"
     * created          datetime
     * created_by      "int(11) unsigned"
     * created_by_alias varchar(255)
     * modified         datetime
     * modified_by  "int(11) unsigned"
     * checked_out  "int(11) unsigned"
     * checked_out_time datetime
     * publish_up      datetime
     * publish_down  datetime
     * images           text
     * urls             text
     * attribs          text
     * version          "int(11) unsigned"
     * parentid         "int(11) unsigned"
     * ordering         int(11)
     * metakey          text
     * metadesc         text
     * access           "int(11) unsigned"
     * hits             "int(11) unsigned"
     * metadata         text
     */
     public function getMyArticle() {
    
            //  Get Component parameters (config.xml)
            $params = JComponentHelper::getParams('com_mycomponent');
    
            //  Get Specific parameter
            $myArticleId = (int) $params->get('articleId', 0);
    
            //  Make sure parameter is set and is greater than zero
            if ($myArticleId > 0) {
    
                //  Build Query
                $query = "SELECT * FROM #__content WHERE id = $myArticleId";
    
                //  Load query into an object
                $db = JFactory::getDBO();
                $db->setQuery($query);
                return $db->loadObject();
            }
    
            //
            return null;
        }
    

    要在后端进行弹出式选择,请修改组件的config.xml

    addpath添加到<params>元素

    <!-- Add the path to content elements -->
    <params addpath="/administrator/components/com_content/elements">
       <!-- Add Select Article param -->
       <param name="articleId" type="article" default="0" label="Select Article" description="" />
    

    您还需要将config按钮添加到组件默认视图

    上的工具栏中
    // Add this code in the display() method of the view
    // @todo change com_mycomponent to your component's name
    JToolBarHelper::preferences('com_mycomponent')
