Alius Tag

It's just a simple class to create tags.

Basic usage

$img = new Tag('img');
print $img; // <img />

$img->src('url')
print $img; // <img src="url" />

$img->alt();
print $img; // <img src="url" alt="" />

$img->alt('Cute cat')
print $img; // <img src="url" alt="Cute cat" />

$img->class('cute');
print $img; // <img src="url" alt="Cute cat" class="cute" />

$img->class('dog');
print $img; // <img src="url" alt="Cute cat" class="dog" />

$img->addClass('cute');
print $img; // <img src="url" alt="Cute cat" class="dog cute" />

$div = new Tag('div');
$div->add($img);
print $div; // <div><img src="url" alt="Cute cat" class="dog cute" /></div>

$div->data('ng-class', 'test');
print $div; // <div data-ng-class="test"><img src="url" alt="Cute cat" class="dog cute" /></div>

Use the render method or cast the class to string to get the html.

Methods

Attributes

object attr ( string $name, mixed $value = null )

Change the attribute. Chainable.

$tag = new Tag('div');
$tag->attr('foo'); // <div foo=""></div>>
$tag->attr('foo', ''); // <div foo=""></div>
$tag->attr('foo', 'bar'); // <div foo="bar"></div>

Preserves the original php type:

$tag->attr('foo', true); // <div foo="1"></div>
$tag->getAttr('foo'); // true

Html entities and double quotes are converted (only when rendered):

$tag->attr('foo', '"foo" \'bar\' <script></script>'); // <div foo="&quot;foo&quot; 'bar' &lt;script&gt;&lt;/script&gt;"></div>
$tag->getAttr('foo'); // "foo" 'bar' <script></script>

mixed getAttr ( string $name )

Get the attribute value.

bool hasAttr ( string $name )

True if the attribute exists. Even if it's empty.

object deleteAttr ( string $name )

Delete the attribute. Chainable.

string renderAttr ( string $name )

Get the attributes in string.

Content

object add ( mixed $value )

Add content. Chainable. The value is converted to string, null or empty string is skipped.

$tag = new Tag('div');
$tag->add('foo')->add('bar'); // <div>foobar</div>

object setContent ( mixed $value )

Replaces the content. Chainable.

bool hasContent

True if there is some content.

object deleteContent

Delete the content. Chainable.

string renderContent

Get the content string.

Class

Helper methods for classes.

object addClass ( $values )

Add class(es). Chainable. Null and empty string skipped. You can pass an array or string. Don't worry about whitespaces.

$tag = new Tag('div');
$tag->addClass('foo')-addClass('bar'); // <div class="foo bar"></div>
$tag->addClass([' a ', ' b c ']); // <div class="foo bar a b c"></div>

object setClass ( $values )

Replace existing classes. Chainable. You can use it with the class pseudo method via __call:

$tag = Tag('img');
$tag->class('test); // <img class="test" />

array getClass ()

Get the classes.

bool hasClass ( $value )

True when the class is set.

object deleteClass ( $values )

Delete one class. Chainable. Deletes the class attribute when you delete the last class.

Data

Helper methods for data attributes.

object data ( $name, $value = null )

Set the data attribute. Chainable.

$tag = new Tag('div');
$tag->data('foo', 'bar'); // <div data-foo="bar"></div>

mixed getData ( $name )

Get the data value. Null if the data is not set.

bool hasData ( $name )

True if there is a data attribute with this name, even if it's empty.

object deleteData ( $name )

Delete the attribute.

Other

Non-existing methods are treated as attributes using the __call method:

$tag = new Tag('img');
$tag->foo('bar')->bar('foo'); // <img foo="bar" bar="foo" />

You can use this class statically:

$tag = Tag::anything(); // <anything></anything>

There is a general factory:

object make ( string $tag )

And there are some useful helper factories:

object form ( string $action, $method = 'post', $token = null )

If the form isn't get or post we change the method to post and add a _method hidden tag:

$tag = Tag::form('url', 'delete');

<form action="url" method="post">
    <input type="hidden" name="_method" value="delete" />
</form>

If you set the token we place a _token hidden tag:

$tag = Tag::form('url', 'post', 'foo bar');

<form action="url" method="post">
    <input type="hidden" name="_token" value="foo bar" />
</form>

object labelFor ( mixed $for, string $text = null )

You can add string or even an other tag:

$tag = Tag::labelFor(Tag::foo()->id('bar'), 'foobar'); // <label for"bar">foobar</label>

object select ( string $name, array $options = [] )

Use it with option tags:

$tag = Tag::select('foo', [
    Tag::option('one', 1),
    Tag::option('two', 2),
    Tag::option('three', 3),
]);

<select name="foo">
    <option value="1">one</option>
    <option value="2">two</option>
    <option value="3">three</option>
</select>

object div ( mixed $content = null )

object span ( mixed $content = null )

object a ( string $href, mixed $content = null )

object img ( string $src )

object caption ( mixed $text = null )

object input ( string $type, string $name, string $value = null )

object checkbox ( string $name, string $value = null, $checked = false )

object radio ( string $name, string $value = null, $checked = false )

object text ( string $name, string $value = null )

object password ( string $name )

object hidden ( string $name, string $value )

object option ( string $text, string $value = null, $selected = false )

object textarea ( string $name, string $value = null )
