未正确查看数据

Question

我正在开发模块安装控制器。当我安装一个模块时，按钮应该显示为修改。但不会因为某些原因

我已经安装了模块的幻灯片如图我VAR转储结果如下

array (size=1) 
    0 => string 'slideshow' (length=9) 

但是，当我重新加载/刷新我的网页属于该模块的按钮仍然说安装。

问：我怎样才能确保如果安装模块按钮，然后让它说修改

控制器

<?php

class Module extends CI_Controller { 

    public function __construct() { 
     parent::__construct(); 
     $this->load->model('extension/model_extension'); 
     $this->load->model('extension/model_module'); 
    } 

    public function install() { 
     $this->model_extension->install('module', $this->uri->segment(4)); 

     redirect('extension/module'); 
    } 

    public function index() { 
     $data['extensions'] = array(); 

     $extensions = $this->model_extension->get_installed('module'); 

     echo '<div class="container-fluid"'; 
     echo '<pre>'; 
     var_dump($extensions); 
     echo '</pre>'; 
     echo '</div>'; 

     $files = glob('controllers/modules/*.php'); 

     if ($files) { 
      foreach ($files as $file) { 

       $extension = basename($file, '.php'); 

       $this->lang->load('module/'. $extension, 'english'); 

       $data['extensions'][] = array(
        'name' => $this->lang->line('heading_title'), 
        'installed' => in_array($extension, $extensions), 
        'install' => site_url('extension/module/install' .'/'. strtolower($extension)), 
        'modify' => site_url('module/' . $extension) 
       ); 
      } 
     } 

     $this->load->view('template/common/header_view'); 
     $this->load->view('template/extension/module_view', $data); 
     $this->load->view('template/common/footer_view'); 
    } 
}

<?php

    public function get_installed($type) { 
     $extension_data = array();

     $this->db->where('code', $code); 
     $this->db->delete($this->db->dbprefix . 'extension');

Answer 1

你知道，如果是通过评估该

in_array($extension, $extensions) 

哪里$extensions是这样

array(
    0 => "extension_name_1", 
    1 => "extension_name_2", 
) 

而且$extension阵列安装或没有扩展名是的方式是通过这个计算 PHP函数

basename($file, '.php'); 

---

PHP basename将返回（例如）extension_name_1.php所以它永远不会匹配您的任何安装的扩展的。

您应该取出basename扩展名，或将其添加到您的安装的扩展阵列的每个位置。
