<h1>Email Helper</h1>

<p>The Email Helper provides some assistive functions for working with Email. For a more robust email solution, see CodeIgniter's <a href="../libraries/email.html">Email Class</a>.</p>

<h2>Loading this Helper</h2>

<p>This helper is loaded using the following code:</p>
<p><code>$this->load->helper('email');</code></p>

<p>The following functions are available:</p>

<h2>valid_email('<var>email</var>')</h2>

<p>Checks if an email is a correctly formatted email. Note that is doesn't actually prove the email will recieve mail, simply that it is a validly formed address.</p>
<p>It returns TRUE/FALSE</p>
<code> $this-&gt;load-&gt;helper('email');<br />
<br />
if (valid_email('email@somesite.com'))<br />
{<br />
&nbsp;&nbsp;&nbsp;&nbsp;echo 'email is valid';<br />
}<br />
else<br />
{<br />
&nbsp;&nbsp;&nbsp;&nbsp;echo 'email is not valid';<br />
}</code>
<h2>send_email('<var>recipient</var>', '<var>subject</var>', '<var>message</var>')</h2>
<p>Sends an email using PHP's native <a href="http://www.php.net/function.mail">mail()</a> function. For a more robust email solution, see CodeIgniter's <a href="../libraries/email.html">Email Class</a>.</p>
