php - CodeIgniter 重命名电子邮件附件文件

Question

我有用于发送带附件的电子邮件的 CodeIgniter 脚本。

$this->ci->email->attach("/path/to/file/myjhxvbXhjdSycv1y.pdf");

效果很好，但我不知道如何将附加文件重命名为一些对用户更友好的字符串？

Answer 1

CodeIgniter v3.x

自 CI v3 以来添加了此功能:

/**
 * Assign file attachments
 *
 * @param   string  $file   Can be local path, URL or buffered content
 * @param   string  $disposition = 'attachment'
 * @param   string  $newname = NULL
 * @param   string  $mime = ''
 * @return  CI_Email
 */
public function attach($file, $disposition = '', $newname = NULL, $mime = '')

根据user guide :

If you’d like to use a custom file name, you can use the third parameter:

$this->email->attach('filename.pdf', 'attachment', 'report.pdf');

CodeIgniter v2.x

但是对于 CodeIgniter v2.x，您可以扩展 Email 库来实现:

1. 创建一份 system/libraries/Email.php 并将其放入 application/libraries/
2. 重命名文件并添加 MY_ 前缀(或您在 config.php 中设置的任何内容)application/libraries/MY_Email.php
3. 打开文件并更改以下内容:

首先:将其插入到 #72 行:

var $_attach_new_name = array();

第二:更改第 #161-166 行的代码 到:

if ($clear_attachments !== FALSE)
{
    $this->_attach_new_name = array();
    $this->_attach_name     = array();
    $this->_attach_type     = array();
    $this->_attach_disp     = array();
}

第三步:在 #409 行找到attach() 函数 并将其更改为:

public function attach($filename, $disposition = 'attachment', $new_name = NULL)
{
    $this->_attach_new_name[] = $new_name;
    $this->_attach_name[]     = $filename;
    $this->_attach_type[]     = $this->_mime_types(pathinfo($filename, PATHINFO_EXTENSION));
    $this->_attach_disp[]     = $disposition; // Can also be 'inline'  Not sure if it matters
    return $this;
}

第四: 最后在 #1143 行 将代码更改为:

$basename = ($this->_attach_new_name[$i] === NULL)
    ? basename($filename) : $this->_attach_new_name[$i];

用法

$this->email->attach('/path/to/fileName.ext', 'attachment', 'newFileName.ext');
