Question

我的模特（action.php）

public function report()
{
  $data = array(
    "user"=> $this->action->get_data());
             //var_dump($data); die();

  $filename ="comment.xls";
  $contents = $this->load->view("Komentar", $data);
  header('Content-type: application/ms-excel');
  header('Content-Disposition: attachment; filename='.$filename);
  echo $contents;
}

My.Controller（Index_cont.php）

<form class="" action="<?php echo base_url('index_cont/report'); ?>" method="post">
    <button class="btn btn-primary" name="submit"  type="submit"> Download Report</button>
</form>

我的观点（index.php）

Komentar.php

问题是我的代码只是查看$contents = $this->load->view("Komentar", $data);（Komentar.php）而不执行下载xls代码。如果我删除该行，它可以下载空白的xls文件。我想在Response Header Request URL: http://localhost:8000/tekinf-ci/index_cont/report Request Method: POST Status Code: 500 Internal Server Error Remote Address: [::1]:8000 Referrer Policy: no-referrer-when-downgrade Cache-Control: no-store, no-cache, must-revalidate Connection: close Content-Length: 1924 Content-Type: text/html; charset=UTF-8 Date: Tue, 10 Apr 2018 13:59:44 GMT Expires: Thu, 19 Nov 1981 08:52:00 GMT Pragma: no-cache Server: Apache/2.4.23 (Win32) OpenSSL/1.0.2h PHP/7.0.9 Set-Cookie: ci_session=ap0r8obbc47nqqcbt1ehrg0u5bffeg17; expires=Tue, 10-Apr-2018 15:59:45 GMT; Max-Age=7200; path=/; HttpOnly X-Powered-By: PHP/7.0.9下载我的数据，而不仅仅是空白页。

Answer 1

您没有返回视图加载的数据，因此您无法echo它，您需要将第3个参数设置为TRUE

$contents = $this->load->view("Komentar", $data, TRUE); // Assign it to $contents

还可以使用CodeIgniter提供的Output库。

您的代码应如下所示：

public function report()
{
    $data = array("user"=> $this->action->get_data());
    $filename = "comment.xls";
    // Set headers
    $this->output->set_content_type('application/ms-excel')
                 ->set_header('Content-Transfer-Encoding: binary')
                 ->set_header('Cache-Control: private, no-transform, no-store, must-revalidate')
                 ->set_header('Content-Disposition: attachment; filename="'.$filename.'"')
                 ->set_output($this->load->view("Komentar", $data, TRUE));
}

Answer 2

您使用创建Excel文件的方式不正确。使用PHPExcel或PhpSpreadsheet库在打开文件时制作excel文件时没有错误。
