的Joomla，添加任務參數爲特定視圖

Question

我嘗試添加URL參數任務=所有車輛，但菜單鏈接到這個觀點後，已創建的任務參數仍然缺席

<?xml version="1.0" encoding="utf-8"?> 
<metadata> 
    <layout title="Multiple Categories"> 
     <message><![CDATA[Displays a selected categories of an application]]></message> 
    </layout> 

    <fields name="params"> 
     <fieldset name="params" addfieldpath="/administrator/components/com_vehiclemanager/elements" label="Params"> 
      <field name="categorylayout" type="categorylayout" default="1" class="inputbox" label="Select layout" multiple ="false" size="1" description="Choose a layout" required="false" /> 
      <field name="back_button" type="list" label="Back Button" required="false" description="Show/Hide a Back Button" > 
       <option value="">Use Global</option> 
       <option value="0">Hide</option> 
       <option value="1">Show</option> 
      </field> 
      <field name="single_category" type="category" default="1" class="inputbox" label="Category" multiple ="true" size="1" description="Choose a vehicle Categories" required="true" /> 
     </fieldset> 
    </fields> 
    <url> 
     <param name="task" value="all_vehicles" ></param> 
    </url> 
</metadata>

你可以試試這個 -

<!-- Add fields to the request variables for the layout. --> 
<fields name="request"> 
    <fieldset name="request">  
     <field name="task" type="hidden" 
      label="" 
      required="" 
      description="" 
      default="all_vehicles" 
     /> 
    </fieldset> 
</fields>
