php - CodeIgniter rename email attachment file -

i have codeigniter script sending email attachments.

$this->ci->email->attach("/path/to/file/myjhxvbxhjdsycv1y.pdf"); 

it works great, have no idea, how rename attached file more user-friendly string?

codeigniter v3.x

this feature has been added since ci v3:

/**  * assign file attachments  *  * @param   string  $file   can 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 user guide:

if you’d use custom file name, can use third parameter:

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

codeigniter v2.x

however codeigniter v2.x, can extend email library implement that:

1. create copy of system/libraries/email.php , put inside application/libraries/
2. rename file , add my_ prefix (or whatever have set in config.php) application/libraries/my_email.php
3. open file , change following:

first: insert @ line #72:

var $_attach_new_name = array(); 

second: change code @ 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 attach() function @ line #409 , change 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 'inline'  not sure if matters     return $this; } 

fourth: @ line #1143 change 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');
