CodeIgniter不加载视图 - 当视图存在时仅加载白色屏幕

I am only getting a white screen for the following code when i go to localhost/Home/Careers

NOTE: When I have the view_name.php file in the views folder, i get white screen of death. If I delete view_name.php from the views folder, I see the "test" and a "cannot find file error".

Any ideas?

<?php
if (!defined('BASEPATH'))exit('No direct script access allowed');

class Home extends CI_Controller {

    public function Careers()
    {
            echo "test";
            $this->load->view('view_name');
    }

}

Probably because you are not mentioning "projectname" before controller name in browser.

Please try in browser with localhost/Project_name/Home/Careers

I solved the problem!

File permissions were wrong ! I did a chmod 755 on the php file and it works perfectly.

Chmod 755 filename.php

> > **In Controller:**

       <?php if (!defined('BASEPATH'))exit('No direct script access
      allowed');

    class Home extends CI_Controller {

    public function Careers()
    {
          $data['test']="test";
          $this->load->view('view_name', $data);
    }

    }

> >  In **view_name.php:**

    <?php
    echo $test; 
    ?>
