A quick example of generating text input with Html-Form using composer:

<input type="button" value="Submit Me"/>
<input type="email" value="example email"/>
<div>example text</div>
<p>example text</p>

Usage

Basic Usage

Accepted arguments

Most of the element accept two arguments:

$default : Default value
$attributes : Array of attributes
echo Html::text($default, attributes);

For options element like select, radio, it accept third argument as $options

$options: Array of options. The array can contains key-value pair or only values
echo Html::select($default, attributes, $options);

using name, id and class

To assign name, id, class or any other attributes, use second arguments ($attributes)

A text field with default value, name, id and class attributes:

echo Html::text('Example_Value', ['name' => 'Example_Name', 'id' => 'Example_ID', 'class' => 'Example_Class']);

Output:

<input type="text" name="Example_Name" value="Example_Value" id="Example_ID" class="Example_Class"/>

Add attributes to element

You can also add any attributes into any element:

echo Html::text('Example_Value', ['name' => 'Example_Name', 'data-example' => 'Example_Data']);

Output:

<input type="text" name="Example_Name" value="Example_Value" data-example="Example_Data"/>

using required, readonly and disabled

echo Html::email(null, ['name' => 'Email', 'required']);
echo Html::email(null, ['name' => 'Email', 'readonly']);
echo Html::email(null, ['name' => 'Email', 'disabled']);

Output:

<input type="email" name="Email" required="required"/>
<input type="email" name="Email" readonly="readonly"/>
<input type="email" name="Email" disabled="disabled"/>

Using label

echo Html::email(null, [
    'name' => 'Example_Name',
    'label' => 'Email'
]);

echo Html::email(null, [
    'name' => 'Example_Name',
    'label' => [
        'Example',
        'class' => 'Class'
    ]
]);

Output:

<label>Email</label>
<input type="email" name="Example_Name"/>

<label class="Class">Example</label>
<input type="email" name="Example_Name"/>

A div with id and class attributes:

echo Html::div('example text', ['id' => 'Example_ID', 'class' => 'Example_Class']);

Output:

<div id="Example_ID" class="Example_Class">example text</div>

lebel with label text, id, class and for attributes

echo Html::label('Some text', ['id' => 'ID', 'class' => 'Class', 'for' => 'For']);

Output:

<label id="ID" class="Class" for="For">Some text</label>

Using checkbox

Simple checkbox with default checked

echo Html::checkbox(true, ['name' => 'Name']);
echo Html::checkbox(true, ['name' => 'Name', 'value' => 'Value']);

Output:

<input type="checkbox" name="Name" value="1" checked="checked"/>
<input type="checkbox" name="Name" value="Value" checked="checked"/>

Pass first argument as false for default unchecked. echo Html::checkbox(false)

List of checkbox

Create a list of checkboxes with default values

echo Html::checkbox('cat', ['name' => 'Name', 'id' => 'ID'], ['dog' => 'Dog', 'cat' => 'Cat']);
echo Html::checkbox(['cat'], ['name' => 'Name', 'id' => 'ID'], ['dog' => 'Dog', 'cat' => 'Cat']);

Output

<label><input type="checkbox" value="dog" name="Name" id="ID_1"/> Dog</label>
<label><input type="checkbox" value="cat" name="Name" id="ID_2" checked="checked"/> Cat</label>

To get array of values by POST or GET method

echo Html::checkbox(['cat'], ['name' => 'Name[]', 'id' => 'ID'], ['dog' => 'Dog', 'cat' => 'Cat']);

Output

<label><input type="checkbox" value="dog" name="Name[]" id="ID_1"/> Dog</label>
<label><input type="checkbox" value="cat" name="Name[]" id="ID_2" checked="checked"/> Cat</label>

Using select / radio

Create a select with default value, name and id attributes

echo Html::select(['cat'], ['name' => 'Name'], ['dog' => 'Dog', 'cat' => 'Cat']);
echo Html::select(['cat'], ['name' => 'Name'], ['dog', 'cat']);

Output

<select name="Name">
    <option value="dog">Dog</option>
    <option value="cat" selected="selected">Cat</option>
</select>

<select name="Name">
    <option value="dog">dog</option>
    <option value="cat" selected="selected">cat</option>
</select>

Create a list of radio

echo Html::radio(['cat'], ['name' => 'Name', 'id' => 'ID'], ['dog', 'cat']);

Output

<label><input type="radio" value="dog" name="Name" id="ID_1"/> dog</label>
<label><input type="radio" value="cat" name="Name" id="ID_2" checked="checked"/> cat</label>

Using collection

Several elements can be grouped together as collection

$div = new Html('div');
$div->p('Hello World');
$div->text('example');
$div->add('Some plain text');
echo $div->render();

Output:

<div>
    <p>Hello World</p>
    <input type="text" value="example"/>
    Some plain text
</div>

Collection uses Html constructor and accept two parameters.

$type (optional): name of tag. (e.g. form, div)
$attributes (optional): array of attributes

Form example

Generating a form using collections:

$form = new Html('form', ['method' => 'POST']);
$form->div('Enter your email and password for login');
$form->email('', ['name' => 'email', 'label' => 'Email']);
$form->password('', ['name' => 'password', 'label' => 'Password']);
$form->submit('login');
echo $form->render();

Output:

<form method="POST">
    <div>Enter your email and password for login</div>
    <label>Email</label>
    <input type="email" name="email"/>
    <label>Password</label>
    <input type="password" name="password"/>
    <input type="submit" value="login"/>
</form>

Nested collections

Generating html template using nested collections:

$html = new Html('html');
$head = $html->import('head');
$head->title('Example Title');
$body = $html->import('body');
$body->p('Hello World');
echo $html->render();

<html>
    <head>
        <title>Example Title</title>
    </head>
    <body>
        <p>Hello World</p>
    </body>
</html>

Using as xml generator

$book = new Html('book');
$book->title('The Da Vinci Code');
$author = $book->import('author');
$author->name('Dan Brown');
$author->nationality('American');
echo $book->render();

Output

<book>
    <title>The Da Vinci Code</title>
    <author>
        <name>Dan Brown</name>
        <nationality>American</nationality>
    </author>
</book>

Advanced

It is possible to create any html element by calling their name.

echo Html::email('noreply@gmail.com');
echo Html::h1('Example Heading');

Under the hood, we use Html::input() for input element and Html::tag() for html tag

Create an email input by using input method:

echo Html::input('email', 'noreply@gmail.com');

Create h1 by using tag method:

echo Html::tag('h1', 'Example Heading');

Add html to before and after elements

echo Html::email('', ['_before' => 'Before', '_after' => 'After']);

Output

Before<input type="email"/>After

Enclose with another element.

echo Html::email('', ['_enclose' => 'div']);
echo Html::email('', ['_enclose' => ['div', 'class' => 'Class']]);

Output

<div>
    <input type="email"/>
</div>
<div class="Class">
    <input type="email"/>
</div>

several way to set options for select / multiselect / radio / checkbox

// Same value and label
echo Html::select(null, [], ['audi', 'bmw']);

// Different value and label
echo Html::select(null, [], ['audi' => 'Audi', 'bmw' => 'BMW']);

// Option with extra attributes
echo Html::select(null, [], ['ferrari' => ['Ferrari', 'data-origin' => 'Italy']]);
echo Html::select(null, [], [['value' => 'ferrari', 'label' => 'Ferrari', 'data-origin' => 'Italy']]);

Output

<select><option value="audi">audi</option><option value="bmw">bmw</option></select>
<select><option value="audi">Audi</option><option value="bmw">BMW</option></select>
<select><option value="ferrari" data-origin="Italy">Ferrari</option></select>
<select><option value="ferrari" data-origin="Italy">Ferrari</option></select>

Mixing several way with one options array

echo Html::select(null, [], [
    'audi',
    'bmw' => 'BMW',
    'honda' => [
        'Honda',
        'data-origin' => 'Japan'
    ],
    [
        'value' => 'ferrari',
        'label' => 'Ferrari',
        'data-origin' => 'Italy'
    ]
]);

Output

<select>
    <option value="audi">audi</option>
    <option value="bmw">BMW</option>
    <option value="honda" data-origin="Japan">Honda</option>
    <option value="ferrari" data-origin="Italy">Ferrari</option>
</select>

Using numeric value

echo Html::select(null, [], [2 => 'Two', 4 => 'Four']);

Output

<select>
    <option value="2">Two</option>
    <option value="4">Four</option>
</select>
