Question

从控制器发送多个变量到视图时出错。 视图中产生错误

Message: Undefined variable: heading

控制器代码：

public function index()
    {
        $this->load->model('database');
        $result['a'] = $this->database->factory_view();
        $this->load->view('header');
        $heading['heading']= '<span class="float-left" style="margin-top:10px;"><h3>Machinery and Factory</h3></span>';
        $this->load->view('factory',$result,$heading);
        $this->load->view('footer');
    }

Answer 1

$data['posts'] = $posts;
$data['comments'] = $comments;
$this->load->view('your_view', $data);

在taemplate中查看...

foreach($posts as $post) {
...
}

foreach($comments as $comm) {
...
}

Answer 2

public function index()
{
    $this->load->model('database');
    $result['a'] = $this->database->factory_view();
    $this->load->view('header');
    $result['heading']= '<span class="float-left" style="margin-top:10px;"><h3>Machinery and Factory</h3></span>';
    $this->load->view('factory',$result);
    $this->load->view('footer');
}

Answer 3

就这样

public function index()
{
    $this->load->model('database');
    $result['a'] = $this->database->factory_view();
    $this->load->view('header');
    $result['heading']= '<span class="float-left" style="margin-top:10px;"> 
  <h3>Machinery and  Factory</h3></span>';
    $result['param_1'] = "xyz";
    $result['param_2'] = "abc";
    $this->load->view('factory',$result);
    $this->load->view('footer');
}

Answer 4

尝试一下。这将起作用...

public function index()
    {
        $this->load->model('database');
        $data['a'] = $this->database->factory_view();
        $this->load->view('header');
        $data['heading']= '<span class="float-left" style="margin-top:10px;"><h3>Machinery and Factory</h3></span>';
        $this->load->view('factory',$data);
        $this->load->view('footer');
    }

然后在您的页面视图内调用$a和$heading。
