我想将一些html代码分配给变量，并且该变量位于控制器中。

此标题出现在应用程序的所有页面中。所以我希望它分配一个名为headerContent的变量，它位于Admin_controller中。该渲染函数从任何另一个扩展Admin_controller的控制器调用，然后将headeview加载到那些页面。
class Admin_controller extends CI_Controller{
function __construct()
{
parent::__construct();
$this->load->model("Adminmodel","",true);
$headerview = 'headerview';
$this->render($headerview); # calling render() function in same class
}
protected $headerview = 'headerview';
protected function render($headerContent) {
$view_data = array( 'headerContent' => $headerContent);
$this->load->view($this->headerview);
}
}
下面的另一个控制器扩展了Admin_controller，称为此render函数。
<?php
require APPPATH . '/controllers/admin/Admin_controller.php';
class Adminhome extends Admin_Controller{
public function __construct(){
parent::__construct();
$this->load->model("Adminmodel","",true);
public function index(){
$data['content']=$this->load->view("admin/adminhomeview",'',true);
$data['title']='Dashboard';
$adminId=$this->session->userdata('cp_adminid');
$permissions=$this->Adminmodel->getpermissions($adminId);
$row = $permissions->row();
$data['isAdmin'] = 0;
if($row->view == 1 or $row->add == 1 or $row->edit == 1 or $row->deleteRole == 1 ){
$data['isAdmin'] = 1;
}
$this->render($headerContent);
// $this->load->view("admin/headerview",$data);
}
}
?>
但它在Adminhome_controller.php中显示错误，如Message：Undefined variable：headerContent。
答案 0 :(得分：1)
您需要创建一个包含
的模板视图文件模板视图：
<html>
<?php $data = array('permission' => $permission); ?>
<?php $this->load->view('templateincludes/header',$data); ?>
<?php $this->load->view($main_content); ?>
<?php $this->load->view('templateincludes/footer'); ?>
</html>
CONTROLER：
$data = array('permission' => '1', 'main_content' => 'folder_to_your_view/view_file_you_want_to_load');
$this->load->view('template', $data);
标题视图：
<?= $permission ?>
答案 1 :(得分：0)
但它显示错误，如消息：未定义变量：headerContent 在Adminhome_controller.php中
扩展类中没有名称为$headerContent的变量。好像你想要访问父/基类的变量。
要解决此问题，您可以在Parent Controller （Admin_controller.php）中声明受保护的字段，并在子控制器内访问它：
class Admin_controller extends CI_Controller{
protected $headerContent; // declare protected field
protected $headerview = 'headerview';
function __construct()
{
parent::__construct();
$this->load->model("Adminmodel","",true);
$headerview = 'headerview';
$this->render($headerview); # calling render() function in same class
}
protected function render($headerContent) {
$view_data = array( 'headerContent' => $headerContent);
$this->headerContent = $headerContent; // assign value into $headerContent field
$this->load->view($this->headerview);
}
}
您可以使用以下方式直接在子类（Adminhome_controller.php）中访问它：
$this->render($this->headerContent);
