Question

我面临的问题（因为我对Joomla组件开发相对较新）关于如何在我的Joomla Custom Component的controller.php中的两个函数之间传递值

以下是我的controller.php文件

 <?php
// No direct access to this file
defined('_JEXEC') or die('Restricted access');

// import Joomla controller library
jimport('joomla.application.component.controller');
JHtml::script(Juri::base() . 'templates/googlemaps/navigation.js');
/**
 * Hello World Component Controller
 */
class HelloWorldController extends JControllerLegacy
{
    function display(){
   echo '<form action="'. echo JRoute::_('index.php?option=com_helloworld&controller=helloworld&task=displayData') .'" method="post">';
   echo '<h1>This is Insert Task</h1><br><input type="text" id="name" placeholder="Name"><br>';
   echo '<input type="text" id="surname" value="surname" name="surname" placeholder="Surname">';
   echo '<input type="submit" value="submit">'; 
   echo '</form>';
    }

    function delete(){
        $id=JRequest::getVar('id');
        echo "You want to delete $id";
    }

    function displayData(){

        $name=JRequest::getVar('name');
        $surname=JRequest::getVar('surname');
        //$mainframe =& JFactory::getApplication();
        //$stateVar = $mainframe->getUserStateFromRequest( "$option.state_variable", "surname", "Hello" );
        echo "Your name is $name and surname is $surname";
        //**How can i get the name and surname variables here after the page refreshes and this task loads**
    }
}

我在控制器的Display（）任务中有两个表单字段，我想获取我在另一个名为displayData（）的任务中的那些字段中输入的值。我想出的唯一方法是使用form的post方法并通过$ _POST []方法获取变量。 Joomla提供用户状态和变量以及所有这些东西，但我无法弄清楚如何在这里使用它们。

首先我注意到你的表单有表格标签因此无法向服务器发送数据。更改代码如下。

    function display(){
       echo '<form action="'. echo JRoute::_('index.php?option=com_helloworld&controller=helloworld&task=displayData') .'" method="post">';
       echo '<h1>This is Insert Task</h1><br><input type="text" id="name" placeholder="Name"><br>';
       echo '<input type="text" id="surname" value="surname" name="surname" placeholder="Surname">';
       echo '<input type="submit" value="submit">'; 
       echo '</form>';       
    }

请注意，您可以更清晰地使用MVC。 MVC是一种安排代码以便更好地开发和调试的形式。您可以创建以下结构。

com_helloworld

控制器
- helloworld.php
模型
- helloworld.php
的观点
- 的HelloWorld
  - view.html.php
  - TMPL
    - 如default.php

在com_helloworld-＆gt; controllers-＆gt; helloworld.php下放这个。

 <?php
// No direct access to this file
defined('_JEXEC') or die('Restricted access');

// import Joomla controller library
jimport('joomla.application.component.controller');
JHtml::script(Juri::base() . 'templates/googlemaps/navigation.js');
/**
 * Hello World Component Controller
 */
class HelloWorldController extends JControllerLegacy
{

    function delete(){
        $id=JRequest::getVar('id');
        echo "You want to delete $id";
    }
    function displayData(){
        // LOAD THE MODEL AND DO PROCESSING THERE
        // $model = $this->getModel();

        $name=JRequest::getVar('name');
        //$surname=JRequest::getVar('surname');
        //$mainframe =& JFactory::getApplication();
        //$stateVar = $mainframe->getUserStateFromRequest("$option.state_variable", "surname", "Hello" );
        echo "Your name is $name and surname is $surname";
        //**How can i get the name and surname variables here after the page refreshes and this task loads**
   }

}

在com_helloworld-＆gt; view-＆gt; tmpl-＆gt; default.php下放这个。

    <form action="<?php echo JRoute::_('index.php?option=com_helloworld&controller=helloworld&task=displayData') ?>" method="post">
    <h1>This is Insert Task</h1><br><input type="text" id="name" placeholder="Name"><br>
    <input type="text" id="surname" value="surname" name="surname" placeholder="Surname">
    <input type="submit" value="submit"> 
    </form>
