-<h1>File Uploading Class</h1>
-
-<p>CodeIgniter's File Uploading Class permits files to be uploaded. You can set various
-preferences, restricting the type and size of the files.</p>
-
-
-<h2>The Process</h2>
-
-<p>Uploading a file involves the following general process:</p>
-
-
-<ul>
-<li>An upload form is displayed, allowing a user to select a file and upload it.</li>
-<li>When the form is submitted, the file is uploaded to the destination you specify.</li>
-<li>Along the way, the file is validated to make sure it is allowed to be uploaded based on the preferences you set.</li>
-<li>Once uploaded, the user will be shown a success message.</li>
-</ul>
-
-<p>To demonstrate this process here is brief tutorial. Afterward you'll find reference information.</p>
-
-<h2>Creating the Upload Form</h2>
-
-
-
-<p>Using a text editor, create a form called <dfn>upload_form.php</dfn>. In it, place this code and save it to your <samp>applications/views/</samp>
-folder:</p>
-
-
-<textarea class="textarea" style="width:100%" cols="50" rows="23">
-&lt;html>
-&lt;head>
-&lt;title>Upload Form&lt;/title>
-&lt;/head>
-&lt;body>
-
-&lt;?php echo $error;?>
-
-&lt;?php echo form_open_multipart('upload/do_upload');?>
-
-&lt;input type="file" name="userfile" size="20" />
-
-&lt;br />&lt;br />
-
-&lt;input type="submit" value="upload" />
-
-&lt;/form>
-
-&lt;/body>
-&lt;/html></textarea>
-
-<p>You'll notice we are using a form helper to create the opening form tag. File uploads require a multipart form, so the helper
-creates the proper syntax for you. You'll also notice we have an $error variable. This is so we can show error messages in the event
-the user does something wrong.</p>
-
-
-<h2>The Success Page</h2>
-
-<p>Using a text editor, create a form called <dfn>upload_success.php</dfn>.
-In it, place this code and save it to your <samp>applications/views/</samp> folder:</p>
-
-<textarea class="textarea" style="width:100%" cols="50" rows="20">&lt;html>
-&lt;head>
-&lt;title>Upload Form&lt;/title>
-&lt;/head>
-&lt;body>
-
-&lt;h3>Your file was successfully uploaded!&lt;/h3>
-
-&lt;ul>
-&lt;?php foreach($upload_data as $item => $value):?>
-&lt;li>&lt;?php echo $item;?>: &lt;?php echo $value;?>&lt;/li>
-&lt;?php endforeach; ?>
-&lt;/ul>
-
-&lt;p>&lt;?php echo anchor('upload', 'Upload Another File!'); ?>&lt;/p>
-
-&lt;/body>
-&lt;/html></textarea>
-
-
-<h2>The Controller</h2>
-
-<p>Using a text editor, create a controller called <dfn>upload.php</dfn>. In it, place this code and save it to your <samp>applications/controllers/</samp>
-folder:</p>
-
-
-<textarea class="textarea" style="width:100%" cols="50" rows="43"><?php
-
-class Upload extends Controller {
-
- function Upload()
- {
- parent::Controller();
- $this->load->helper(array('form', 'url'));
- }
-
- function index()
- {
- $this->load->view('upload_form', array('error' => ' ' ));
- }
-
- function do_upload()
- {
- $config['upload_path'] = './uploads/';
- $config['allowed_types'] = 'gif|jpg|png';
- $config['max_size'] = '100';
- $config['max_width'] = '1024';
- $config['max_height'] = '768';
-
- $this->load->library('upload', $config);
-
- if ( ! $this->upload->do_upload())
- {
- $error = array('error' => $this->upload->display_errors());
-
- $this->load->view('upload_form', $error);
- }
- else
- {
- $data = array('upload_data' => $this->upload->data());
-
- $this->load->view('upload_success', $data);
- }
- }
-}
-?></textarea>
-
-
-<h2>The Upload Folder</h2>
-
-<p>You'll need a destination folder for your uploaded images. Create a folder at the root of your CodeIgniter installation called
-<dfn>uploads</dfn> and set its file permissions to 777.</p>
-
-
-<h2>Try it!</h2>
-
-<p>To try your form, visit your site using a URL similar to this one:</p>
-
-<code>example.com/index.php/<var>upload</var>/</code>
-
-<p>You should see an upload form. Try uploading an image file (either a jpg, gif, or png). If the path in your
-controller is correct it should work.</p>
-
-
-<p>&nbsp;</p>
-
-<h1>Reference Guide</h1>
-
-
-<h2>Initializing the Upload Class</h2>
-
-<p>Like most other classes in CodeIgniter, the Upload class is initialized in your controller using the <dfn>$this->load->library</dfn> function:</p>
-
-<code>$this->load->library('upload');</code>
-<p>Once the Upload class is loaded, the object will be available using: <dfn>$this->upload</dfn></p>
-
-
-<h2>Setting Preferences</h2>
-
-<p>Similar to other libraries, you'll control what is allowed to be upload based on your preferences. In the controller you
-built above you set the following preferences:</p>
-
-<code>$config['upload_path'] = './uploads/';<br />
-$config['allowed_types'] = 'gif|jpg|png';<br />
-$config['max_size'] = '100';<br />
-$config['max_width'] = '1024';<br />
-$config['max_height'] = '768';<br />
-<br />
-$this->load->library('upload', $config);<br /><br />
-
-// Alternately you can set preferences by calling the initialize function. Useful if you auto-load the class:<br />
-$this->upload->initialize($config);</code>
-
-<p>The above preferences should be fairly self-explanatory. Below is a table describing all available preferences.</p>
-
-
-<h2>Preferences</h2>
-
-<p>The following preferences are available. The default value indicates what will be used if you do not specify that preference.</p>
-
-<table cellpadding="0" cellspacing="1" border="0" style="width:100%" class="tableborder">
-<tr>
-<th>Preference</th>
-<th>Default&nbsp;Value</th>
-<th>Options</th>
-<th>Description</th>
-</tr>
-
-<tr>
-<td class="td"><strong>upload_path</strong></td>
-<td class="td">None</td>
-<td class="td">None</td>
-<td class="td">The path to the folder where the upload should be placed. The folder must be writable and the path can be absolute or relative.</td>
-</tr>
-
-<tr>
-<td class="td"><strong>allowed_types</strong></td>
-<td class="td">None</td>
-<td class="td">None</td>
-<td class="td">The mime types corresponding to the types of files you allow to be uploaded. Usually the file extension can be used as the mime type. Separate multiple types with a pipe.</td>
-</tr>
-
-
-<tr>
-<td class="td"><strong>overwrite</strong></td>
-<td class="td">FALSE</td>
-<td class="td">TRUE/FALSE (boolean)</td>
-<td class="td">If set to true, if a file with the same name as the one you are uploading exists, it will be overwritten. If set to false, a number will be appended to the filename if another with the same name exists.</td>
-</tr>
-
-
-<tr>
-<td class="td"><strong>max_size</strong></td>
-<td class="td">0</td>
-<td class="td">None</td>
-<td class="td">The maximum size (in kilobytes) that the file can be. Set to zero for no limit. Note: Most PHP installations have their own limit, as specified in the php.ini file. Usually 2 MB (or 2048 KB) by default.</td>
-</tr>
-
-<tr>
-<td class="td"><strong>max_width</strong></td>
-<td class="td">0</td>
-<td class="td">None</td>
-<td class="td">The maximum width (in pixels) that the file can be. Set to zero for no limit.</td>
-</tr>
-
-<tr>
-<td class="td"><strong>max_height</strong></td>
-<td class="td">0</td>
-<td class="td">None</td>
-<td class="td">The maximum height (in pixels) that the file can be. Set to zero for no limit.</td>
-</tr>
-
-<tr>
-<td class="td"><strong>max_filename</strong></td>
-<td class="td">0</td>
-<td class="td">None</td>
-<td class="td">The maximum length that a file name can be. Set to zero for no limit.</td>
-</tr>
-
-<tr>
-<td class="td"><strong>encrypt_name</strong></td>
-<td class="td">FALSE</td>
-<td class="td">TRUE/FALSE (boolean)</td>
-<td class="td">If set to TRUE the file name will be converted to a random encrypted string. This can be useful if you would like the file saved with a name that can not be discerned by the person uploading it.</td>
-</tr>
-
-<tr>
-<td class="td"><strong>remove_spaces</strong></td>
-<td class="td">TRUE</td>
-<td class="td">TRUE/FALSE (boolean)</td>
-<td class="td">If set to TRUE, any spaces in the file name will be converted to underscores. This is recommended.</td>
-</tr>
-</table>
-
-
-<h2>Setting preferences in a config file</h2>
-
-<p>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 <var>upload.php</var>, add the <var>$config</var>
-array in that file. Then save the file in: <var>config/upload.php</var> and it will be used automatically. You
-will NOT need to use the <dfn>$this->upload->initialize</dfn> function if you save your preferences in a config file.</p>
-
-
-<h2>Function Reference</h2>
-
-<p>The following functions are available</p>
-
-
-<h2>$this->upload->do_upload()</h2>
-
-<p>Performs the upload based on the preferences you've set. Note: By default the upload routine expects the file to come from a form field
-called <dfn>userfile</dfn>, and the form must be a "multipart type:</p>
-
-<code>&lt;form method="post" action="some_action" enctype="multipart/form-data" /></code>
-
-<p>If you would like to set your own field name simply pass its value to the <dfn>do_upload</dfn> function:</p>
-
-<code>
-$field_name = "some_field_name";<br />
-$this->upload->do_upload($field_name)</code>
-
-
-<h2>$this->upload->display_errors()</h2>
-
-<p>Retrieves any error messages if the <dfn>do_upload()</dfn> function returned false. The function does not echo automatically, it
-returns the data so you can assign it however you need.</p>
-
-<h3>Formatting Errors</h3>
-<p>By default the above function wraps any errors within &lt;p> tags. You can set your own delimiters like this:</p>
-
-<code>$this->upload->display_errors('<var>&lt;p></var>', '<var>&lt;/p></var>');</code>
-
-<h2>$this->upload->data()</h2>
-
-<p>This is a helper function that returns an array containing all of the data related to the file you uploaded.
-Here is the array prototype:</p>
-
-<code>Array<br />
-(<br />
-&nbsp;&nbsp;&nbsp;&nbsp;[file_name]&nbsp;&nbsp;&nbsp;&nbsp;=> mypic.jpg<br />
-&nbsp;&nbsp;&nbsp;&nbsp;[file_type]&nbsp;&nbsp;&nbsp;&nbsp;=> image/jpeg<br />
-&nbsp;&nbsp;&nbsp;&nbsp;[file_path]&nbsp;&nbsp;&nbsp;&nbsp;=> /path/to/your/upload/<br />
-&nbsp;&nbsp;&nbsp;&nbsp;[full_path]&nbsp;&nbsp;&nbsp;&nbsp;=> /path/to/your/upload/jpg.jpg<br />
-&nbsp;&nbsp;&nbsp;&nbsp;[raw_name]&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;=> mypic<br />
-&nbsp;&nbsp;&nbsp;&nbsp;[orig_name]&nbsp;&nbsp;&nbsp;&nbsp;=> mypic.jpg<br />
-&nbsp;&nbsp;&nbsp;&nbsp;[file_ext]&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;=> .jpg<br />
-&nbsp;&nbsp;&nbsp;&nbsp;[file_size]&nbsp;&nbsp;&nbsp;&nbsp;=> 22.2<br />
-&nbsp;&nbsp;&nbsp;&nbsp;[is_image]&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;=> 1<br />
-&nbsp;&nbsp;&nbsp;&nbsp;[image_width]&nbsp;&nbsp;=> 800<br />
-&nbsp;&nbsp;&nbsp;&nbsp;[image_height] => 600<br />
-&nbsp;&nbsp;&nbsp;&nbsp;[image_type]&nbsp;&nbsp;&nbsp;=> jpeg<br />
-&nbsp;&nbsp;&nbsp;&nbsp;[image_size_str] => width="800" height="200"<br />
-)</code>
-

+<h2>Try it!</h2>
+
+<p>To try your form, visit your site using a URL similar to this one:</p>
+
+<code>example.com/index.php/<var>upload</var>/</code>
+
+<p>You should see an upload form. Try uploading an image file (either a jpg, gif, or png). If the path in your
+controller is correct it should work.</p>
+
+
+<p>&nbsp;</p>
+
+<h1>Reference Guide</h1>
+
+
+<h2>Initializing the Upload Class</h2>
+
+<p>Like most other classes in CodeIgniter, the Upload class is initialized in your controller using the <dfn>$this->load->library</dfn> function:</p>
+
+<code>$this->load->library('upload');</code>
+<p>Once the Upload class is loaded, the object will be available using: <dfn>$this->upload</dfn></p>
+
+
+<h2>Setting Preferences</h2>
+
+<p>Similar to other libraries, you'll control what is allowed to be upload based on your preferences. In the controller you
+built above you set the following preferences:</p>
+
+<code>$config['upload_path'] = './uploads/';<br />
+$config['allowed_types'] = 'gif|jpg|png';<br />
+$config['max_size'] = '100';<br />
+$config['max_width'] = '1024';<br />
+$config['max_height'] = '768';<br />
+<br />
+$this->load->library('upload', $config);<br /><br />
+
+// Alternately you can set preferences by calling the initialize function. Useful if you auto-load the class:<br />
+$this->upload->initialize($config);</code>
+
+<p>The above preferences should be fairly self-explanatory. Below is a table describing all available preferences.</p>
+
+
+<h2>Preferences</h2>
+
+<p>The following preferences are available. The default value indicates what will be used if you do not specify that preference.</p>
+
+<table cellpadding="0" cellspacing="1" border="0" style="width:100%" class="tableborder">
+<tr>
+<th>Preference</th>
+<th>Default&nbsp;Value</th>
+<th>Options</th>
+<th>Description</th>
+</tr>
+
+<tr>
+<td class="td"><strong>upload_path</strong></td>
+<td class="td">None</td>
+<td class="td">None</td>
+<td class="td">The path to the folder where the upload should be placed. The folder must be writable and the path can be absolute or relative.</td>
+</tr>
+
+<tr>
+<td class="td"><strong>allowed_types</strong></td>
+<td class="td">None</td>
+<td class="td">None</td>
+<td class="td">The mime types corresponding to the types of files you allow to be uploaded. Usually the file extension can be used as the mime type. Separate multiple types with a pipe.</td>
+</tr>
+
+
+<tr>
+<td class="td"><strong>overwrite</strong></td>
+<td class="td">FALSE</td>
+<td class="td">TRUE/FALSE (boolean)</td>
+<td class="td">If set to true, if a file with the same name as the one you are uploading exists, it will be overwritten. If set to false, a number will be appended to the filename if another with the same name exists.</td>
+</tr>
+
+
+<tr>
+<td class="td"><strong>max_size</strong></td>
+<td class="td">0</td>
+<td class="td">None</td>
+<td class="td">The maximum size (in kilobytes) that the file can be. Set to zero for no limit. Note: Most PHP installations have their own limit, as specified in the php.ini file. Usually 2 MB (or 2048 KB) by default.</td>
+</tr>
+
+<tr>
+<td class="td"><strong>max_width</strong></td>
+<td class="td">0</td>
+<td class="td">None</td>
+<td class="td">The maximum width (in pixels) that the file can be. Set to zero for no limit.</td>

+<td class="td"><strong>max_height</strong></td>
+<td class="td">0</td>
+<td class="td">None</td>
+<td class="td">The maximum height (in pixels) that the file can be. Set to zero for no limit.</td>

+</tr>
+
+<tr>
+<td class="td"><strong>encrypt_name</strong></td>
+<td class="td">FALSE</td>
+<td class="td">TRUE/FALSE (boolean)</td>
+<td class="td">If set to TRUE the file name will be converted to a random encrypted string. This can be useful if you would like the file saved with a name that can not be discerned by the person uploading it.</td>
+</tr>
+
+<tr>
+<td class="td"><strong>remove_spaces</strong></td>
+<td class="td">TRUE</td>
+<td class="td">TRUE/FALSE (boolean)</td>
+<td class="td">If set to TRUE, any spaces in the file name will be converted to underscores. This is recommended.</td>
+</tr>
+</table>
+
+
+<h2>Setting preferences in a config file</h2>
+
+<p>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 <var>upload.php</var>, add the <var>$config</var>
+array in that file. Then save the file in: <var>config/upload.php</var> and it will be used automatically. You
+will NOT need to use the <dfn>$this->upload->initialize</dfn> function if you save your preferences in a config file.</p>
+
+
+<h2>Function Reference</h2>
+
+<p>The following functions are available</p>
+
+
+<h2>$this->upload->do_upload()</h2>
+
+<p>Performs the upload based on the preferences you've set. Note: By default the upload routine expects the file to come from a form field
+called <dfn>userfile</dfn>, and the form must be a "multipart type:</p>
+
+<code>&lt;form method="post" action="some_action" enctype="multipart/form-data" /></code>
+
+<p>If you would like to set your own field name simply pass its value to the <dfn>do_upload</dfn> function:</p>
+
+<code>
+$field_name = "some_field_name";<br />
+$this->upload->do_upload($field_name)</code>
+
+
+<h2>$this->upload->display_errors()</h2>
+
+<p>Retrieves any error messages if the <dfn>do_upload()</dfn> function returned false. The function does not echo automatically, it
+returns the data so you can assign it however you need.</p>
+
+<h3>Formatting Errors</h3>
+<p>By default the above function wraps any errors within &lt;p> tags. You can set your own delimiters like this:</p>
+
+<code>$this->upload->display_errors('<var>&lt;p></var>', '<var>&lt;/p></var>');</code>
+
+<h2>$this->upload->data()</h2>
+
+<p>This is a helper function that returns an array containing all of the data related to the file you uploaded.
+Here is the array prototype:</p>
+
+<code>Array<br />
+(<br />
+&nbsp;&nbsp;&nbsp;&nbsp;[file_name]&nbsp;&nbsp;&nbsp;&nbsp;=> mypic.jpg<br />
+&nbsp;&nbsp;&nbsp;&nbsp;[file_type]&nbsp;&nbsp;&nbsp;&nbsp;=> image/jpeg<br />
+&nbsp;&nbsp;&nbsp;&nbsp;[file_path]&nbsp;&nbsp;&nbsp;&nbsp;=> /path/to/your/upload/<br />
+&nbsp;&nbsp;&nbsp;&nbsp;[full_path]&nbsp;&nbsp;&nbsp;&nbsp;=> /path/to/your/upload/jpg.jpg<br />
+&nbsp;&nbsp;&nbsp;&nbsp;[raw_name]&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;=> mypic<br />
+&nbsp;&nbsp;&nbsp;&nbsp;[orig_name]&nbsp;&nbsp;&nbsp;&nbsp;=> mypic.jpg<br />
+&nbsp;&nbsp;&nbsp;&nbsp;[file_ext]&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;=> .jpg<br />
+&nbsp;&nbsp;&nbsp;&nbsp;[file_size]&nbsp;&nbsp;&nbsp;&nbsp;=> 22.2<br />
+&nbsp;&nbsp;&nbsp;&nbsp;[is_image]&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;=> 1<br />
+&nbsp;&nbsp;&nbsp;&nbsp;[image_width]&nbsp;&nbsp;=> 800<br />
+&nbsp;&nbsp;&nbsp;&nbsp;[image_height] => 600<br />
+&nbsp;&nbsp;&nbsp;&nbsp;[image_type]&nbsp;&nbsp;&nbsp;=> jpeg<br />
+&nbsp;&nbsp;&nbsp;&nbsp;[image_size_str] => width="800" height="200"<br />
+)</code>
