现在我正在尝试在控制器类中创建一些应该更新博客文章的函数。在控制器超类中，有一个函数可以通过 url 中的方法名和参数执行函数。当我将视图定向到编辑功能时，编辑功能可以正常工作。但是，当 set 方法将任务数组更改为更新时，它应该重定向 url 以执行更新功能。然而，它并没有这样做。我尝试在更新函数中添加参数，我尝试在更新函数中删除所有参数。我什至尝试编辑视图，以便它在任务数组设置为更新时再次提交。在声明任务集方法时，我究竟应该做什么来调用更新函数。如果我的措辞听起来令人困惑，我深表歉意，但它'
这是 Controller 超类的代码
<?php
class Controller {
public $load;
public $data = array();
function __construct($view, $method = null, $parameters = null){
//instantiate the load class
$this->load = new Load();
new Model();
//run any task methods
if($method){
$this->runTask($method, $parameters);
}else{
$this->defaultTask();
}
//render the view
$this->load->view($view.'.php', $this->data);
}
/*
*The runTask() method is our way of grabbing the method from the URI string and parsing the parameters
*/
public function runTask($method, $parameters = null){
if($method && method_exists($this, $method)) {
//the call_user_func_array expects an array so we create a null array if parameters is empty
if(!is_array($parameters)){
$parameters = array();
}
call_user_func_array(array($this, $method), $parameters);
}
}
/*
*The defaultTask() method is the one run if no task method is run. Here as a placeholder for child classes.
*/
public function defaultTask(){
}
/*
*The set() method allows us to more easily set the view variables
*/
public function set($key, $value){
$this->data[$key] = $value;
}
}
这是控制器的子类，其中编辑和更新功能
<?php
class AddPostController extends Controller{
public $postObject;
public function defaultTask(){
$this->postObject = new Post();
$this->set('task', 'add');
}
public function add(){
$this->postObject = new Post();
$data = array('title'=>$_POST['post_title'],'content'=>$_POST['post_content'],
'categoryID'=>$_POST['categoryID'],'date'=>$_POST['date']);
$result = $this->postObject->addPost($data);
$this->set('message', $result);
}
public function edit($pID){
$this->postObject = new Post();
$post = $this->postObject->getPost($pID);
$this->set('pID', $post['pID']);
$this->set('date', $post['date']);
$this->set('categoryID', $post['categoryID']);
$this->set('title', $post['title']);
$this->set('content', $post['content']);
$this->set('task', 'update'); //This should redirect to update method
}
public function update() {
echo 'controller update';
echo sizeof($data);
echo sizeof($this->data);
//$this->postObject->update($data);
}
}
这是添加或编辑帖子视图
