72<li>CC and BCCs</li>
73<li>HTML or Plaintext email</li>
74<li>Attachments</li>
75<li>Word wrapping</li>
76<li>Priorities</li>
77<li>BCC Batch Mode, enabling large email lists to be broken into small BCC batches.</li>
78<li>Email Debugging tools</li>
79</ul>

81
82<h2>Sending Email</h2>
83
84<p>Sending email is not only simple, but you can configure it on the fly or set your preferences in a config file.</p>
85
86<p>Here is a basic example demonstrating how you might send email. Note: This example assumes you are sending the email from one of your
87<a href="../general/controllers.html">controllers</a>.</p>
88
89<code>$this->load->library('email');<br />
90<br />
91$this->email->from('your@your-site.com', 'Your Name');<br />
92$this->email->to('someone@some-site.com'); <br />
93$this->email->cc('another@another-site.com'); <br />
94$this->email->bcc('them@their-site.com'); <br />
95<br />
96$this->email->subject('Email Test');<br />
97$this->email->message('Testing the email class.'); <br />
98<br />
99$this->email->send();<br />
100<br />
101echo $this->email->print_debugger();</code>
102
103
104
105
106<h2>Setting Email Preferences</h2>
107
108<p>There are 17 different preferences available to tailor how your email messages are sent. You can either set them manually
109as described here, or automatically via preferences stored in your config file, described below:</p>
110
111<p>Preferences are set by passing an array of preference values to the email <dfn>initialize</dfn> function. Here is an example of how you might set some preferences:</p>
112
113<code>$config['protocol'] = 'sendmail';<br />
114$config['mailpath'] = '/usr/sbin/sendmail';<br />
115$config['charset'] = 'iso-8859-1';<br />
116$config['wordwrap'] = TRUE;<br />
117<br />
118$this->email->initialize($config);</code>
119
120<p><strong>Note:</strong> Most of the preferences have default values that will be used if you do not set them.</p
121
122<h3>Setting Email Preferences in your Config File</h3>
123
124<p>If you prefer not to set preferences using the above method, you can instead put them into a config file.
125Simply create a new file called the <var>email.php</var>, add the <var>$config</var>
126array in that file. Then save the file at <var>config/email.php</var> and it will be used automatically. You
127will NOT need to use the <dfn>$this->email->initialize()</dfn> function if you save your preferences in a config file.</p>
128
129
130
131
132<h2>Email Preferences</h2>
133
134<p>The following is a list of all the preferences that can be set when sending email.</p>

215
admin83b05a82006-09-25 21:06:46 +0000[diff] [blame]216<h3>$this->email->set_alt_message()</h3>
adminb0dd10f2006-08-25 17:25:49 +0000[diff] [blame]217<p>Sets the alternative email message body:</p>
admin83b05a82006-09-25 21:06:46 +0000[diff] [blame]218<code>$this->email->set_alt_message('<var>This is the alternative message</var>');</code>
adminb0dd10f2006-08-25 17:25:49 +0000[diff] [blame]219
220<p>This is an optional message string which can be used if you send HTML formatted email. It lets you specify an alternative
221message with no HTML formatting which is added to the header string for people who do not accept HTML email.
222If you do not set your own message Code Igniter will extract the message from your HTML email and strip the tags.</p>
223
224
225
226<h3>$this->email->clear()</h3>
227<p>Initializes all the email variables to an empty state. This function is intended for use if you run the email sending function
228in a loop, permitting the data to be reset between cycles.</p>
229<code>foreach ($list as $name => $address)<br />
230{<br />
231&nbsp;&nbsp;&nbsp;&nbsp;$this->email->clear();<br /><br />
232
233&nbsp;&nbsp;&nbsp;&nbsp;$this->email->to($address);<br />
234&nbsp;&nbsp;&nbsp;&nbsp;$this->email->from('your@your-site.com');<br />
235&nbsp;&nbsp;&nbsp;&nbsp;$this->email->subject('Here is your info '.$name);<br />
236&nbsp;&nbsp;&nbsp;&nbsp;$this->email->message('Hi '.$name.' Here is the info you requested.');<br />
237&nbsp;&nbsp;&nbsp;&nbsp;$this->email->send();<br />
238}</code>
239
adminec5a5a62006-09-21 00:45:03 +0000[diff] [blame]240<p>If you set the parameter to TRUE any attachments will be cleared as well:</p>
241
242<code>$this->email->clear(TRUE);</code>
243
adminb0dd10f2006-08-25 17:25:49 +0000[diff] [blame]244
245<h3>$this->email->send()</h3>
adminec5a5a62006-09-21 00:45:03 +0000[diff] [blame]246<p>The Email sending function. Returns boolean TRUE or FALSE based on success or failure, enabling it to be used
247conditionally:</p>
248
249<code>if ( ! $this->email->send())<br />
250{<br />
251&nbsp;&nbsp;&nbsp;&nbsp;// Generate error<br />
252}</code>
adminb0dd10f2006-08-25 17:25:49 +0000[diff] [blame]253
254
255<h3>$this->email->attach()</h3>
256<p>Enables you to send an attachment. Put the file path/name in the first parameter. Note: Use a file path, not a URL.
257For multiple attachments use the function multiple times. For example:</p>
258
259<code>$this->email->attach('/path/to/photo1.jpg');<br />
260$this->email->attach('/path/to/photo2.jpg');<br />
261$this->email->attach('/path/to/photo3.jpg');<br />
262<br />
263$this->email->send();</code>
264
265
266<h3>$this->email->print_debugger()</h3>
267<p>Returns a string containing any server messages, the email headers, and the email messsage. Useful for debugging.</p>
268
269
270<h2>Overriding Word Wrapping</h2>
271
272<p>If you have word wrapping enabled (recommended to comply with RFC 822) and you have a very long link in your email it can
273get wrapped too, causing it to become un-clickable by the person receiving it. Code Igniter lets you manually override
274word wrapping within part of your message like this:
275
276<code>The text of your email that<br />
277gets wrapped normally.<br />
278<br />
279<var>{unwrap}</var>http://www.some-site.com/a_long_link_that_should_not_be_wrapped.html<var>{/unwrap}</var><br />
280<br />
281More text that will be<br />
282wrapped normally.</code>
283
284<p>Place the item you do not want word-wrappd between: <var>{unwrap}</var> <var>{/unwrap}</var>
