README

Yii HTML

The package provides various tools to help with dynamic server-side generation of HTML:

• Tag classes A, Address, Article, Aside, Audio, B, Body, Br, Button, Caption, Col, Colgroup, Datalist, Div, Em, Fieldset, Footer, Form, H1, H2, H3, H4, H5, H6, Header, Hr, Hgroup, Html, I, Img, Input (and specialized Checkbox, Radio, Range, File), Label, Legend, Li, Link, Meta, Nav, Noscript, Ol, Optgroup, Option, P, Picture, Script, Section, Select, Small, Source, Span, Strong, Style, Table, Tbody, Td, Textarea, Tfoot, Th, Thead, Title, Tr, Track, Ul, Video.
• CustomTag class that helps to generate custom tag with any attributes.
• HTML widgets ButtonGroup, CheckboxList and RadioList.
• All tags content is automatically HTML-encoded. There is NoEncode class designed to wrap content that should not be encoded.
• Html helper that has static methods to generate HTML, create tags and HTML widget objects.

Note that for simple static-HTML cases, it is preferred to use HTML directly.

Requirements

• PHP 8.1 or higher.

Installation

The package could be installed with Composer:

composer require yiisoft/html

General usage

<?php
use Yiisoft\Html\Html;
use Yiisoft\Html\Tag\Meta;
?>

<?= Meta::pragmaDirective('X-UA-Compatible', 'IE=edge') ?>
<?= Meta::data('viewport', 'width=device-width, initial-scale=1') ?>

<?= Html::cssFile(
    'https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/css/bootstrap.min.css',
    [
        'integrity' => 'sha384-ggOyR0iXCbMQv3Xipma34MD+dH/1fQ784/j6cY/iJTQUOhcWr7x9JvoRxT2MZw1T',
        'crossorigin' => 'anonymous'
    ]
) ?>
<?= Html::cssFile('/css/site.css', ['rel' => 'stylesheet']) ?>

<?= Html::openTag('footer', ['class' => 'footer']) ?>
    <?= Html::openTag('div', ['class' => 'container flex-fill']) ?>
        <?= Html::p('', ['class' => 'float-left']) ?>
        <?= Html::p()
            ->class('float-right')
            ->content(
                'Powered by ',
                Html::a(
                    'Yii Framework',
                    'https://www.yiiframework.com/',
                    ['rel' => 'external']
                )
            ) ?>
    <?= Html::closeTag('div') ?>
<?= Html::closeTag('footer') ?>

Tag objects usage

Tag classes allow working with a tag as an object and then get an HTML code by using render() method or type casting to string. For example, the following code:

echo \Yiisoft\Html\Tag\Div::tag()
    ->content(
        \Yiisoft\Html\Tag\A::tag()
            ->mailto('[e-mail]')
            ->content('contact us')
            ->render()
    )
    ->encode(false)
    ->id('ContactEmail')
    ->class('red');

... will generate the following HTML:

<div id="ContactEmail" class="red"><a href="mailto:[e-mail]">contact us</a></div>

Generating custom tags

To generate custom tags, use the CustomTag class. For example, the following code:

echo \Yiisoft\Html\Tag\CustomTag::name('b')
    ->content('text')
    ->attribute('title', 'Important');

... will generate the following HTML:

<b title="Important">text</b>

Encoding tags content

By default, stringable objects that implement \Yiisoft\Html\NoEncodeStringableInterface are not encoded, everything else is encoded.

To change this behavior use encode() method passing one of the following values:

• null: default behavior;
• true: any content is encoded;
• false: nothing is encoded.

Note: all bundled tags and widgets implement \Yiisoft\Html\NoEncodeStringableInterface interface and are not encoded by default when passed as content. Their own content is encoded.

Examples:

// <b>&lt;i&gt;hello&lt;/i&gt;</b>
echo Html::b('<i>hello</i>');

// <b><i>hello</i></b>
echo Html::b('<i>hello</i>')->encode(false);

// <b><i>hello</i></b>
echo Html::b(Html::i('hello'));

// <b>&lt;i&gt;hello&lt;/i&gt;</b>
echo Html::b(Html::i('hello'))->encode(true);

In order to mark a string as "do not encode" you can use \Yiisoft\Html\NoEncode class:

// <b><i>hello</i></b>
echo Html::b(NoEncode::string('<i>hello</i>'));

HTML widgets usage

There are multiple widgets that do not directly represent any HTML tag, but a set of tags. These help to express complex HTML in simple PHP.

ButtonGroup

Represents a group of buttons.

echo \Yiisoft\Html\Widget\ButtonGroup::create()
   ->buttons(
       \Yiisoft\Html\Html::resetButton('Reset Data'),
       \Yiisoft\Html\Html::resetButton('Send'),
   )
   ->containerAttributes(['class' => 'actions'])
   ->buttonAttributes(['form' => 'CreatePost']);

Result will be:

<div class="actions">
<button type="reset" form="CreatePost">Reset Data</button>
<button type="reset" class="primary" form="CreatePost">Send</button>
</div>

CheckboxList

Represents a list of checkboxes.

echo \Yiisoft\Html\Widget\CheckboxList\CheckboxList::create('count')
    ->items([1 => 'One', 2 => 'Two', 5 => 'Five'])
    ->uncheckValue(0)
    ->value(2, 5)
    ->containerAttributes(['id' => 'main']);

Result will be:

<input type="hidden" name="count" value="0">
<div id="main">
<label><input type="checkbox" name="count[]" value="1"> One</label>
<label><input type="checkbox" name="count[]" value="2" checked> Two</label>
<label><input type="checkbox" name="count[]" value="5" checked> Five</label>
</div>

RadioList

Represents a list of radio buttons.

echo \Yiisoft\Html\Widget\RadioList\RadioList::create('count')
    ->items([1 => 'One', 2 => 'Two', 5 => 'Five'])
    ->uncheckValue(0)
    ->value(2)
    ->containerAttributes(['id' => 'main']);

Result will be:

<input type="hidden" name="test" value="0">
<div id="main">
<label><input type="radio" name="test" value="1"> One</label>
<label><input type="radio" name="test" value="2" checked> Two</label>
<label><input type="radio" name="test" value="5"> Five</label>
</div>

Html helper usage

Html helper methods are static so usage is:

echo \Yiisoft\Html\Html::a('Yii Framework', 'https://www.yiiframework.com/');

Overall the helper has the following method groups.
