-<h1>Input Class</h1>
-
-<p>The Input Class serves two purposes:</p>
-
-<ol>
-<li>It pre-processes global input data for security.</li>
-<li>It provides some helper functions for fetching input data and pre-processing it.</li>
-</ol>
-
-<p class="important"><strong>Note:</strong> This class is initialized automatically by the system so there is no need to do it manually.</p>
-
-
-<h2>Security Filtering</h2>
-
-<p>The security filtering function is called automatically when a new <a href="../general/controllers.html">controller</a> is invoked.  It does the following:</p>
-
-<ul>
-<li>Destroys the global GET array.  Since CodeIgniter does not utilize GET strings, there is no reason to allow it.</li>
-<li>Destroys all global variables in the event register_globals is turned on.</li>
-<li>Filters the POST/COOKIE array keys, permitting only alpha-numeric (and a few other) characters.</li>
-<li>Provides XSS (Cross-site Scripting Hacks) filtering.  This can be enabled globally, or upon request.</li>
-<li>Standardizes newline characters to \n</li>
-</ul>
-
-
-<h2>XSS Filtering</h2>
-
-<p>CodeIgniter comes with a Cross Site Scripting Hack prevention filter which can either run automatically to filter
-all POST and COOKIE data that is encountered, or you can run it on a per item basis.  By default it does <strong>not</strong>
-run globally since it requires a bit of processing overhead, and since you may not need it in all cases.</p>
-
-<p>The XSS filter looks for commonly used techniques to trigger Javascript or other types of code that attempt to hijack cookies
-or do other malicious things.  If anything disallowed is encountered it is rendered safe by converting the data to character entities.</p>
-
-<p>
-Note: This function should only be used to deal with data upon submission. It's not something that should be used for general runtime processing since it requires a fair amount of processing overhead.</p>
-
-
-<p>To filter data through the XSS filter use this function:</p>
-
-<h2>$this->input->xss_clean()</h2>
-
-<p>Here is an usage example:</p>
-
-<code>$data = $this->input->xss_clean($data);</code>
-
-<p>If you want the filter to run automatically every time it encounters POST or COOKIE data you can enable it by opening your
-<kbd>application/config/config.php</kbd> file and setting this:</p>
-
-<code>$config['global_xss_filtering'] = TRUE;</code>
-
-<p>Note: If you use the form validation class, it gives you the option of XSS filtering as well.</p>
-
-<p>An optional second parameter, <dfn>is_image</dfn>, allows this function to be used to test images for potential XSS attacks, useful for file upload security.  When this second parameter is set to <dfn>TRUE</dfn>, instead of returning an altered string, the function returns TRUE if the image is safe, and FALSE if it contained potentially malicious information that a browser may attempt to execute.</p>
-
-<code>if ($this->input->xss_clean($file, TRUE) === FALSE)<br />
-{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;// file failed the XSS test<br />
-}</code>
-
-
-<h2>Using POST, COOKIE, or SERVER Data</h2>
-
-<p>CodeIgniter comes with three helper functions that let you fetch POST, COOKIE or SERVER items.  The main advantage of using the provided
-functions rather than fetching an item directly ($_POST['something']) is that the functions will check to see if the item is set and
-return false (boolean) if not.  This lets you conveniently use data without having to test whether an item exists first.
-In other words, normally you might do something like this:</p>
-
-<code>
-if ( ! isset($_POST['something']))<br />
-{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;$something = FALSE;<br />
-}<br />
-else<br />
-{<br />
-&nbsp;&nbsp;&nbsp;&nbsp;$something = $_POST['something'];<br />
-}</code>
-
-<p>With CodeIgniter's built in functions you can simply do this:</p>
-
-<code>$something = $this->input->post('something');</code>
-
-<p>The three functions are:</p>
-
-<ul>
-<li>$this->input->post()</li>
-<li>$this->input->cookie()</li>
-<li>$this->input->server()</li>
-</ul>
-
-<h2>$this->input->post()</h2>
-
-<p>The first parameter will contain the name of the POST item you are looking for:</p>
-
-<code>$this->input->post('some_data');</code>
-
-<p>The function returns FALSE (boolean) if the item you are attempting to retrieve does not exist.</p>
-
-<p>The second optional parameter lets you run the data through the XSS filter.  It's enabled by setting the second parameter to boolean TRUE;</p>
-
-<code>$this->input->post('some_data', TRUE);</code>
-
-<h2>$this->input->get()</h2>
-
-<p>This function is identical to the post function, only it fetches get data:</p>
-
-<code>$this->input->get('some_data', TRUE);</code>
-
-<h2>$this->input->get_post()</h2>
-
-<p>This function will search through both the post and get streams for data, looking first in post, and then in get:</p>
-
-<code>$this->input->get_post('some_data', TRUE);</code>
-
-<h2>$this->input->cookie()</h2>
-
-<p>This function is identical to the post function, only it fetches cookie data:</p>
-
-<code>$this->input->cookie('some_data', TRUE);</code>
-
-<h2>$this->input->server()</h2>
-
-<p>This function is identical to the above functions, only it fetches server data:</p>
-
-<code>$this->input->server('some_data');</code>
-
-
-
-
-<h2>$this->input->ip_address()</h2>
-<p>Returns the IP address for the current user.  If the IP address is not valid, the function will return an IP of: 0.0.0.0</p>
-<code>echo $this->input->ip_address();</code>
-
-
-<h2>$this->input->valid_ip(<var>$ip</var>)</h2>
-
-<p>Takes an IP address as input and returns TRUE or FALSE (boolean) if it is valid or not.  Note:  The $this->input->ip_address() function above
-validates the IP automatically.</p>
-
-<code>if ( ! $this-&gt;input-&gt;valid_ip($ip))<br />
-{<br />
-&nbsp;&nbsp;&nbsp;&nbsp; echo 'Not Valid';<br />
-}<br />
-else<br />
-{<br />
-&nbsp;&nbsp;&nbsp;&nbsp; echo 'Valid';<br />
-}</code>
-
-
-<h2>$this->input->user_agent()</h2>
-<p>Returns the user agent (web browser) being used by the current user. Returns FALSE if it's not available.</p>
-<code>echo $this->input->user_agent();</code>
