Sending Email

+ +

Sending email is not only simple, but you can configure it on the fly or set your preferences in a config file.

+ +

Here is a basic example demonstrating how you might send email. Note: This example assumes you are sending the email from one of your +controllers.

+ +

$this->load->library('email');

+

+$this->email->from('your@your-site.com', 'Your Name');
	
+$this->email->to('someone@some-site.com'); 

+$this->email->cc('another@another-site.com'); 

+$this->email->bcc('them@their-site.com'); 

+

+$this->email->subject('Email Test');

+$this->email->message('Testing the email class.');	

+

+$this->email->send();

+

+echo $this->email->print_debugger();

+ + + + +

Setting Email Preferences

+ +

There are 17 different preferences available to tailor how your email messages are sent. You can either set them manually +as described here, or automatically via preferences stored in your config file, described below:

+ +

Preferences are set by passing an array of preference values to the email initialize function. Here is an example of how you might set some preferences:

+ +

$config['protocol'] = 'sendmail';

+$config['mailpath'] = '/usr/sbin/sendmail';

+$config['charset'] = 'iso-8859-1';

+$config['wordwrap'] = TRUE;

+

+$this->email->initialize($config);

+ +

Note: Most of the preferences have default values that will be used if you do not set them.

Setting Email Preferences in your Config File + +

If you prefer not to set preferences using the above method, you can instead put them into a config file. +Simply create a new file called the email.php, add the $config +array in that file. Then save the file at config/email.php and it will be used automatically. You +will NOT need to use the $this->email->initialize() function if you save your preferences in a config file.

+ + + + +

Email Preferences

+ +

The following is a list of all the preferences that can be set when sending email.

+ + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +

Preference	Default Value	Options	Description

Email Function Reference

+ +

$this->email->from()

Sets the email address and name of the person sending the email:

+$this->email->from('you@your-site.com', 'Your Name'); + +

$this->email->reply_to()

Sets the reply-to address. If the information is not provided the information in the "from" function is used. Example:

+$this->email->reply_to('you@your-site.com', 'Your Name'); + + +

$this->email->to()

Sets the email address(s) of the recipient(s). Can be a single email, a comma-delimited list or an array:

+ +$this->email->to('someone@some-site.com'); +$this->email->to('one@some-site.com, two@some-site.com, three@some-site.com'); + +

$list = array('one@some-site.com, two@some-site.com, three@some-site.com');


+$this->email->to('$list');

+ +

$this->email->cc()

Sets the CC email address(s). Just like the "to", can be a single email, a comma-delimited list or an array.

+ +

$this->email->bcc()

Sets the BCC email address(s). Just like the "to", can be a single email, a comma-delimited list or an array.

+ + +

$this->email->subject()

Sets the email subject:

+$this->email->subject('This is my subject'); + +

$this->email->message()

Sets the email message body:

+$this->email->message('This is my message'); + +

$this->email->alt_message()

Sets the alternative email message body:

+$this->email->alt_message('This is the alternative message'); + +

This is an optional message string which can be used if you send HTML formatted email. It lets you specify an alternative +message with no HTML formatting which is added to the header string for people who do not accept HTML email. +If you do not set your own message Code Igniter will extract the message from your HTML email and strip the tags.

+ + + +

$this->email->clear()

Initializes all the email variables to an empty state. This function is intended for use if you run the email sending function +in a loop, permitting the data to be reset between cycles.

foreach ($list as $name => $address)

+{

+    $this->email->clear();


+	
+    $this->email->to($address);

+    $this->email->from('your@your-site.com');

+    $this->email->subject('Here is your info '.$name);

+    $this->email->message('Hi '.$name.' Here is the info you requested.');

+    $this->email->send();

+}

+ + +

$this->email->send()

The Email sending function. Returns boolean TRUE or FALSE based on success for failure, enabling it to be used +conditionally.

+ + +

$this->email->attach()

Enables you to send an attachment. Put the file path/name in the first parameter. Note: Use a file path, not a URL. +For multiple attachments use the function multiple times. For example:

+ +

$this->email->attach('/path/to/photo1.jpg');

+$this->email->attach('/path/to/photo2.jpg');

+$this->email->attach('/path/to/photo3.jpg');

+

+$this->email->send();

+ + +

$this->email->print_debugger()

Returns a string containing any server messages, the email headers, and the email messsage. Useful for debugging.

+ + +

Overriding Word Wrapping

+ +

If you have word wrapping enabled (recommended to comply with RFC 822) and you have a very long link in your email it can +get wrapped too, causing it to become un-clickable by the person receiving it. Code Igniter lets you manually override +word wrapping within part of your message like this: + +The text of your email that +gets wrapped normally. + +{unwrap}http://www.some-site.com/a_long_link_that_should_not_be_wrapped.html{/unwrap} + +More text that will be +wrapped normally. + +

Place the item you do not want word-wrappd between: {unwrap} {/unwrap} + + +
