<h1>HTML Helper</h1>

<p>The HTML Helper file contains functions that assist in working with HTML.</p>

<ul>
	<li><a href="#br">br()</a></li>
	<li><a href="#heading">heading()</a></li>
	<li><a href="#img">img()</a></li>
	<li><a href="#link_tag">link_tag()</a></li>
	<li><a href="#nbs">nbs()</a></li>
	<li><a href="#ol_and_ul">ol() and ul()</a></li>
	<li><a href="#meta">meta()</a></li>
	<li><a href="#doctype">doctype()</a></li>
</ul>

<h2>Loading this Helper</h2>

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

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

<h2><a name="br"></a>br()</h2>
<p>Generates line break tags (&lt;br />) based on the number you submit. Example:</p>
<code>echo br(3);</code>
<p>The above would produce: &lt;br />&lt;br />&lt;br /></p>

<h2><a name="heading"></a>heading()</h2>
<p>Lets you create HTML &lt;h1> tags.  The first parameter will contain the data, the
second the size of the heading.  Example:</p>
<code>echo heading('Welcome!', 3);</code>
<p>The above would produce:  &lt;h3>Welcome!&lt;/h3></p>

<p>Additionally, in order to add attributes to the heading tag such as HTML classes, ids or inline styles, a third parameter is available.</p>
<code>echo heading('Welcome!', 3, 'class="pink"')</code>
<p>The above code produces: &lt;h3 class="pink">Welcome!<&lt;h3></p>


<h2><a name="img"></a>img()</h2>
<p>Lets you create HTML &lt;img /&gt; tags.  The first parameter  contains the image source. Example:</p>
<code>echo img('images/picture.jpg');<br />
// gives &lt;img src=&quot;http://site.com/images/picture.jpg&quot; /&gt;</code>
<p>There is an optional second parameter that is a TRUE/FALSE value that specifics if the src should have the page specified by $config['index_page'] added to the address it creates. Presumably, this would be if you were using a media controller.</p>
<p><code>echo img('images/picture.jpg', TRUE);<br />
// gives &lt;img src=&quot;http://site.com/index.php/images/picture.jpg&quot; alt=&quot;&quot; /&gt;</code></p>
<p>Additionally, an associative array can be passed to the img() function for complete control over all attributes and values. If an alt attribute is not provided, CodeIgniter will generate an empty string.</p>
<p><code> $image_properties = array(<br />
	&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'src' =&gt; 'images/picture.jpg',<br />
	&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'alt' =&gt; 'Me, demonstrating how to eat 4 slices of pizza at one time',<br />
	&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'class' =&gt; 'post_images',<br />
	&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'width' =&gt; '200',<br />
	&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'height' =&gt; '200',<br />
	&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'title' =&gt; 'That was quite a night',<br />
	&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'rel' =&gt; 'lightbox',<br />
	);<br />
	<br />
	img($image_properties);<br />
	// &lt;img src=&quot;http://site.com/index.php/images/picture.jpg&quot; alt=&quot;Me, demonstrating how to eat 4 slices of pizza at one time&quot; class=&quot;post_images&quot; width=&quot;200&quot; height=&quot;200&quot; title=&quot;That was quite a night&quot; rel=&quot;lightbox&quot; /&gt;</code></p>

<h2><a name="link_tag"></a>link_tag()</h2>
<p>Lets you create HTML &lt;link /> tags.  This is useful for stylesheet links, as well as other links. The parameters are href, with optional rel, type, title, media and index_page. index_page is a TRUE/FALSE value that specifics if the href should have the page specified by $config['index_page'] added to the address it creates.<code>
echo link_tag('css/mystyles.css');<br />
// gives &lt;link href=&quot;http://site.com/css/mystyles.css&quot; rel=&quot;stylesheet&quot; type=&quot;text/css&quot; /&gt;</code></p>
<p>Further examples:</p>

<code>
	echo link_tag('favicon.ico', 'shortcut icon', 'image/ico');<br />
	// &lt;link href=&quot;http://site.com/favicon.ico&quot; rel=&quot;shortcut icon&quot; type=&quot;image/ico&quot; /&gt;
	<br />
	<br />
	echo link_tag('feed', 'alternate', 'application/rss+xml', 'My RSS Feed');<br />
	// &lt;link href=&quot;http://site.com/feed&quot; rel=&quot;alternate&quot; type=&quot;application/rss+xml&quot; title=&quot;My RSS Feed&quot; /&gt; </code>
<p>Additionally, an associative array can be passed to the link() function for complete control over all attributes and values.</p>
<p><code>
	$link = array(<br />
	&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'href' =&gt; 'css/printer.css',<br />
	&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'rel' =&gt; 'stylesheet',<br />
	&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'type' =&gt; 'text/css',<br />
	&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'media' =&gt; 'print'<br />
	);<br />
	<br />
	echo link_tag($link);<br />
	// &lt;link href=&quot;http://site.com/css/printer.css&quot; rel=&quot;stylesheet&quot; type=&quot;text/css&quot; media=&quot;print&quot; /&gt;</code></p>

<h2><a name="nbs"></a>nbs()</h2>
<p>Generates non-breaking spaces (&amp;nbsp;) based on the number you submit. Example:</p>
<code>echo nbs(3);</code>
<p>The above would produce: &amp;nbsp;&amp;nbsp;&amp;nbsp;</p>

<h2><a name="ol_and_ul"></a>ol()&nbsp; and&nbsp; ul()</h2>

<p>Permits you to generate ordered or unordered HTML lists from simple or multi-dimensional arrays. Example:</p>

<code>
$this->load->helper('html');<br />
<br />
$list = array(<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'red', <br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'blue', <br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'green',<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'yellow'<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;);<br />
<br />
$attributes = array(<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'class' => 'boldlist',<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'id'&nbsp;&nbsp;&nbsp;&nbsp;=> 'mylist'<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;);<br />
<br />
echo ul($list, $attributes);<br />
</code>

<p>The above code will produce this:</p>

<code>
&lt;ul&nbsp;class="boldlist"&nbsp;id="mylist"><br />
&nbsp;&nbsp;&lt;li>red&lt;/li><br />
&nbsp;&nbsp;&lt;li>blue&lt;/li><br />
&nbsp;&nbsp;&lt;li>green&lt;/li><br />
&nbsp;&nbsp;&lt;li>yellow&lt;/li><br />
&lt;/ul>
</code>

<p>Here is a more complex example, using a multi-dimensional array:</p>

<code>
$this->load->helper('html');<br />
<br />
$attributes = array(<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'class' => 'boldlist',<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'id'&nbsp;&nbsp;&nbsp;&nbsp;=> 'mylist'<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;);<br />
<br />
$list = array(<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'colors' => array(<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'red',<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'blue',<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'green'<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;),<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'shapes' => array(<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'round', <br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'square',<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'circles' => array(<br />

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'oval', <br />

<h2><a name="meta"></a>meta()</h2>

<p>Helps you generate meta tags.  You can pass strings to the function, or simple arrays, or multidimensional ones. Examples:</p>

<code>
echo meta('description', 'My Great site');<br />
// Generates:  &lt;meta name="description" content="My Great Site" /><br />
<br /><br />

echo meta('Content-type', 'text/html; charset=utf-8', 'equiv'); // Note the third parameter.  Can be "equiv" or "name"<br />
// Generates:  &lt;meta http-equiv="Content-type" content="text/html; charset=utf-8" /><br />

<br /><br />

echo meta(array('name' => 'robots', 'content' => 'no-cache'));<br />
// Generates:  &lt;meta name="robots" content="no-cache" /><br />

<br /><br />

$meta = array(<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;array('name' => 'robots', 'content' => 'no-cache'),<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;array('name' => 'description', 'content' => 'My Great Site'),<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;array('name' => 'keywords', 'content' => 'love, passion, intrigue, deception'),<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;array('name' => 'robots', 'content' => 'no-cache'),<br />
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;array('name' => 'Content-type', 'content' => 'text/html; charset=utf-8', 'type' => 'equiv')<br />
&nbsp;&nbsp;&nbsp;&nbsp;);<br />
<br />
echo meta($meta);
<br />
// Generates:  <br />
// &lt;meta name="robots" content="no-cache" /><br />
// &lt;meta name="description" content="My Great Site" /><br />
// &lt;meta name="keywords" content="love, passion, intrigue, deception" /><br />
// &lt;meta name="robots" content="no-cache" /><br />
// &lt;meta http-equiv="Content-type" content="text/html; charset=utf-8" />
</code>


<h2><a name="doctype"></a>doctype()</h2>

<p>Helps you generate document type declarations, or DTD's. XHTML 1.0 Strict is used by default, but many doctypes are available.</p>

<code>
echo doctype();<br />
// &lt;!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"&gt;<br />
<br />
echo doctype('html4-trans');<br />
// &lt;!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd"&gt;
</code>

<p>The following is a list of doctype choices.  These are configurable, and pulled from <samp>application/config/doctypes.php</samp></p>
