HTML Helper

The HTML Helper file contains functions that assist in working with HTML.

Loading this Helper

This helper is loaded using the following code:

$this->load->helper('html');

The following functions are available:

br()

Generates line break tags (<br />) based on the number you submit. Example:

echo br(3);

The above would produce: <br /><br /><br />

heading()

Lets you create HTML <h1> tags. The first parameter will contain the data, the second the size of the heading. Example:

echo heading('Welcome!', 3);

The above would produce: <h3>Welcome!</h3>

link()

Lets you create HTML <link /> tags. 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.

While stylesheets are more conveniently handled through the stylesheet() function, they can also be called here.


link('css/mystyles.css');

    // gives <link href="http://site.com/css/mystyles.css" rel="stylesheet" type="text/css" />

Further examples:


link('favicon.ico', 'shortcut icon', 'image/ico');

    // <link href="http://site.com/favicon.ico" rel="shortcut icon" type="image/ico" /> 




link('feed', 'alternate', 'application/rss+xml', 'My RSS Feed');

    // <link href="http://site.com/feed" rel="alternate" type="application/rss+xml" title="My RSS Feed" /> 






$link = array(

              'href' => 'css/printer.css',

              'rel' => 'stylesheet',

              'type' => 'text/css',

              'media' => 'print'

    );

    

    link($link);

    // <link href="http://site.com/css/printer.css" rel="stylesheet" type="text/css" media="print" />

nbs()

Generates non-breaking spaces ( ) based on the number you submit. Example:

echo nbs(3);

The above would produce:    

ol() and ul()

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


$this->load->helper('html');



$list = array(

            'red', 

            'blue', 

            'green',

            'yellow'

            );



$attributes = array(

                    'class' => 'boldlist',

                    'id'    => 'mylist'

                    );



echo ul($list, $attributes);

The above code will produce this:


<ul class="boldlist" id="mylist">

  <li>red</li>

  <li>blue</li>

  <li>green</li>

  <li>yellow</li>

</ul>

Here is a more complex example, using a multi-dimensional array:


$this->load->helper('html');



$list = array(

            'colors' => array(

                                'red',

                                'blue',

                                'green'

                            ),

            'shapes' => array(

                                'round', 

                                'square',

                                'circles' => array(

                                                    'ellipse', 

                                                    'oval', 

                                                    'sphere'

                                                    )

                            ),

            'moods'    => array(

                                'happy', 

                                'upset' => array(

                                                    'defeated' => array(

                                                                        'dejected',

                                                                        'disheartened',

                                                                        'depressed'

                                                                        ),

                                                    'annoyed',

                                                    'cross',

                                                    'angry'

                                                )

                            )

            );





echo ul($list);
