在 Codeigniter 中重定向

发布于 2024-12-19 04:23:33 字数 622 浏览 4 评论 0原文

我有一个分页显示，在每个页面调用中我将当前 URI 字符串设置到会话中（在我的控制器中）。

$current = $this->uri->uri_string();
$this->session->set_userdata('return_to', $current);

从视图中，用户可以单击链接转到其他地方（编辑表单），提交后（并且表单验证正确）我想返回到分页结果的正确页面。

if($this->form_validation->run('edit') == TRUE )
{
    $back_to = NULL;
    $back_to = '/'.$this->session->userdata('return_to');
    ....
    redirect($back_to);
}

似乎有时在 Firefox 中工作，但在 Chrome 中死机，重定向到 favicon.ico

任何和所有帮助都表示赞赏

更新： 我的问题不是由于相对/绝对地址造成的，由于第二个控制器中的某些奇怪原因，重定向的目标是 favicon.ico，而不是会话中存储的内容。

原文

I have a paginated display in which on each page call I set the current URI string into a session (in my controller).

$current = $this->uri->uri_string();
$this->session->set_userdata('return_to', $current);

From the view the user can click a link to go somewhere else (an edit form), which when submitted (and form validation is correct) I want to return to the correct page of the paginated results.

if($this->form_validation->run('edit') == TRUE )
{
    $back_to = NULL;
    $back_to = '/'.$this->session->userdata('return_to');
    ....
    redirect($back_to);
}

Seems to work sometimes in Firefox but dies in Chrome, redirect to favicon.ico

Any and all help appreciated

UPDATE:
My problem isn't due to relative/absolute addresses, for some weird reason in the second controller the redirect aims to favicon.ico, not what was stored in the session.

if($this->form_validation->run() == TRUE )
{
    if($this->session->userdata('return_to')
    {
       redirect($this->session->userdata('return_to'));
    }
    else
    {
      redirect(base_url());
     // or trigger some error
    }
}

不需要分配变量，redirect() 使用完整的 url 和分段的 url（很像 site_url()，这正是 uri_string() 返回的内容）因此

，如果这不起作用，则可能是您的会话未设置或已过期。此外，请考虑 CI 的会话是 cookie ，因此浏览器可以在其中发挥作用。

if($this->form_validation->run() == TRUE )
{
    if($this->session->userdata('return_to')
    {
       redirect($this->session->userdata('return_to'));
    }
    else
    {
      redirect(base_url());
     // or trigger some error
    }
}

Don't need to assign a variable, redirect() uses both a full url and a segmented url (much like site_url(), which is exactly what is returned by uri_string().

So if this doesn't work, it's likely your session is not set or expired. Also, consider that CI's sessions are cookies , so a browser can has its role in here.

我会使用绝对 URL，而不是相对 URL。

尝试一下

if($this->form_validation->run('edit') == TRUE )
{
    $back_to = NULL;
    $back_to = 'http://www.mydomain.com/'.$this->session->userdata('return_to');
    ....
    redirect($back_to);
}

正如 Stealthyninja 指出的那样，最好使用 CodeIgniter 的 site_url() 或 base_url() 而不是对其进行硬编码。在 config.php 中设置 site_url() （我相信）

I would use an absolute URL and not a relative one.

Try this

if($this->form_validation->run('edit') == TRUE )
{
    $back_to = NULL;
    $back_to = 'http://www.mydomain.com/'.$this->session->userdata('return_to');
    ....
    redirect($back_to);
}

As stealthyninja pointed out it's probably better to use CodeIgniter's site_url() or base_url() instead of hard coding it. Set the site_url() in the config.php (i believe)
