Codeigniter：下载文件并重定向 [英] Codeigniter: download file and redirect

问题描述

我在此页面上有一个表格 http://www.obsia.com/products/thassos_wonder_brochure/
点击提交时，我希望它开始下载文件，并重定向到谢谢页面。但是我只能下载文件或重定向或加载感谢下载页面。

I have a form on this page http://www.obsia.com/products/thassos_wonder_brochure/ On hitting submit, I want it start downloading the file and also get redirected to thank you page. But I can only get it either download the file or redirect or load the thank for downloading page.

这是检查表单并提交的功能：

This is the function for checking the form and submiting:

function thassos_wonder_brochure()
{
    $this->load->helper('form');
    $this->load->helper('email');
    $this->load->library('email');
    $this->load->library('form_validation');

    //form validation
    $this->form_validation->set_rules('firstname', 'First Name', 'required|max_length[32]');
    $this->form_validation->set_rules('lastname', 'Last Name', 'required|max_length[32]');
    $this->form_validation->set_rules('companyemail', 'Company Email', 'required|max_length[100]|valid_email|unique');

    $this->load->model('brochure_model');
    if ($this->form_validation->run() == FALSE) 
    {
        // redisplay user form and repopulate fields
        $this->load->view('/tw/thassos_wonder_brochure_view');
    }   
    //display confirmation web page and send email
    else
    {   

        if($query = $this->brochure_model->addContact())
        {
            redirect('/thankyou/thassos_wonder_download');  (UPDATE)    
        }   
    }

}

下面的代码在谢谢页面上，以重定向到下载页面结尾：（UPDATE）

Below is the code is on the thank you page ending with redirect to the download page: (UPDATE)

    <?php $this->load->view('header_view.php'); ?>
    <div class="prod">
    <?php $this->load->view('pmenu_view');?>

<div class="product_desc" id="tw_download">
    <h1>Thank you for Downloading</h1>
    <p>You have downloaded the brochure for ThassosWonder - for white stones specifically. You will also receive further information and link to the downloads in your email after you click on the confirmation link in your email.</p>
    <?php echo br(1); ?>
    <p>Feel free to write to us, if you are unable <?php echo anchor('contact', 'to get desired finish from your white marble or stones')?>. You can upload a picture to get a thorough analysis from our Research Director.</p>
    <br />

</div>
    </div>
    <?php $this->load->view('footer_view');?>  
<?php redirect('download/thassos_wonder_brochure'); ?>

这是我在下载页面上使用的代码。

This is the code I used on the download page. How can I download the file and also redirect it to thank you page.

<?php 
$this->load->helper('download');
$name = 'ThassosWonder.pdf';
$data = file_get_contents("./downloads/brochures/Thassos_Wonder_Obsia.pdf"); // Read the file's contents - cannot use relative path. It will try to call the file from same directory (controller) as this file. In order for it get the contents from the root folder put a . in front of the relative path//
force_download($name, $data); 
 ?>

任何帮助将不胜感激。

推荐答案

执行另一种方法-重定向到谢谢页面，然后立即重定向到强制下载页面。这将开始下载，但将用户保留在谢谢页面上。

Do it the other way around - redirect to the 'thank you' page and immediately redirect to the 'force download' page. This will start the download but leave the user on the 'thank you' page.

更新：
尝试更改

UPDATE: Try changing

<?php redirect('download/thassos_wonder_brochure'); ?>

到

<?php redirect('download/thassos_wonder_brochure', 'refresh'); ?>
