CodeIgniter重命名电子邮件附件文件 [英] CodeIgniter rename email attachment file

问题描述

  $ this-> ci - >的电子邮件 - >附加（ /路径/到/文件/ myjhxvbXhjdSycv1y.pdf）; 
  

它的效果很好，但我不知道如何重命名附加文件到一些更加用户友好的字符串？

解决方案

CodeIgniter v3.x

此功能已添加自 CI v3 ：

  / ** 
 *分配文件附件
 * 
 * @param string $ file可以是本地路径，URL或缓冲内容
 * @param string $ disposition ='attachment'
 * @param string $ newname = NULL 
 * @param （$ file，$ disposition =''，$ newname = NULL，$ mime =''）
 $ $ b  

根据用户指南：

如果要使用自定义文件名，可以使用第三个
参数：

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

---

CodeIgniter v2.x

但是对于CodeIgniter v2.x，您可以扩展电子邮件库来实现：

1. 创建一个 system / libraries / Email.php 的副本，并将其放在 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：

第一个：在 ＃72 ：

  var $ _attach_new_name = array（）; 
  

第二个更改代码 ＃161-166 to：

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

第三：查找 attach（）函数在 ＃409 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; //也可以是'inline'不确定是否重要
 return $ this; 
} 
  

第四：最后在 a href =https://github.com/bcit-ci/CodeIgniter/blob/2.2.6/system/libraries/Email.php#L1143 =noreferrer>＃1143 将代码更改为：

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

用法

I have CodeIgniter script for sending email with attachments.

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

It works great, but I have no idea, how rename attached file to some more user-friendly string?

解决方案

CodeIgniter v3.x

This feature has been added since CI v3:

/**
 * 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 = '')

According to the 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

However for CodeIgniter v2.x, you can extend the Email library to implement that:

1. Create a copy of system/libraries/Email.php and put it inside application/libraries/
2. Rename the file and add MY_ prefix (or whatever you have set in config.php) application/libraries/MY_Email.php
3. Open the file and change the following:

First: Insert this at line #72:

var $_attach_new_name = array();

Second: Change the code at line #161-166 to:

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

Third: Find the attach() function at line #409 and change it to:

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;
}

Fourth: Finally at line #1143 change the code to:

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

Usage

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