According to doc

force_download([$filename = ''[, $data = ''[, $set_mime = FALSE]]])

Parameters:

• $filename (string)
• $data (mixed)
• $set_mime (bool) – Whether to try to send the actual MIME type

Return type: void

Generates server headers which force data to be downloaded to yourdesktop. Useful with file downloads. The first parameter is the nameyou want the downloaded file to be named, the second parameter is thefile data.

If you set the second parameter to NULL and $filename is an existing,readable file path, then its content will be read instead.

If you set the third parameter to boolean TRUE, then the actual fileMIME type (based on the filename extension) will be sent, so that ifyour browser has a handler for that type - it can use it.

一般用法

    $this->load->helper('download');
    force_download('/path/to/pdf.pdf', NULL);

具体情况的使用 - 放置在 Controller 中

function file_download()
    {
        $file_name= $this->input->get('file_name');

        $this->load->helper('download');
        $data = file_get_contents($file_name);
        $name = 'My_new_name.pdf'; // custom file name for your download

        force_download($name, $data);
        //force_download($file_name, NULL); will get the file name for you
}

HTML假设您有这样的下载链接

<a class="downloadable" href="/Resumes/Resumes1271354404687.pdf">
    /Resumes/Resumes1271354404687.pdf
</a>

Javascript

$(function(){
  $('.downloadable').click(function(){
  
     window.location.href = "<?php echo site_url('CONTROLLER_NAME/file_download') ?>?file_name="+ $(this).attr('href');
  });
});
