Usage

Basics

First create a class instance of HtmlBuilder. Than create a class intance of HtmlElement or HtmlElementInterface. The Instance is given the tag h2 as first parameter and the content of the element as second parameter.

use Naucon\HtmlBuilder\HtmlBuilder;
$htmlBuilder = new HtmlBuilder();

use Naucon\HtmlBuilder\HtmlElement;
$htmlElement = new HtmlElement('h2', 'My Headline');
echo $htmlBuilder->render($htmlElement);

// Output:
// <h2>My Headline</h2>

You can use concrete html elements like headlines, forms, tables and more. In this example we create a instance of HtmlHeadline to render a <h2> html element.

use Naucon\HtmlBuilder\HtmlHeadline;
$headline = new HtmlHeadline('My Headline', 2);
echo $htmlBuilder->render($headline);

// Output:
// <h2>My Headline</h2>

Content

A content of the html elements contain can either be set over the constructor or the method setContent().

$htmlElementObject = new HtmlDiv('foo');
echo $htmlBuilder->render($htmlElementObject);

// Output:
// <div>foo</div>

$htmlElementObject = new HtmlDiv();
$htmlElementObject->setContent('foo');
echo $htmlBuilder->render($htmlElementObject);

// Output:
// <div>foo</div>

A html element instance can also be set as content.

$htmlElementObject = new HtmlDiv();
$htmlElementObject->setContent(new HtmlHeadline('Main headline', 1));
echo $htmlBuilder->render($htmlElementObject);

// Output:
// <div><h1>Main headline</h1></div>

To append a content use the method addContent().

$htmlElementObject = new HtmlDiv('foo');
$htmlElementObject->addContent(new HtmlHeadline('Main headline', 1));
echo $htmlBuilder->render($htmlElementObject);

// Output:
// <div>foo<h1>Main headline</h1></div>

Attributes

Every instance of html element have the following methods access and modify attributes:

getAttributes() html element attributes with key-value-pairs hasAttributes() html element has attributes setAttributes() html element attributes with key-value-pairs getAttribute($key) return html element attribute value of a given key hasAttribute($key) has html element attribute of a given key setAttribute($key, $value=null) set a html element attribute value of a given key appendAttribute($key, $value=null, $seperater=null) append a html element attribute value of a given key

Example:

$htmlElementObject = new HtmlDiv('foo');
$htmlElementObject->setAttribute('id', 'bar');
echo $htmlBuilder->render($htmlElementObject);

// Output:
// <div id="bar">foo</div>

$htmlElementObject = new HtmlDiv('foo');
$htmlElementObject->setAttribute('class', 'btn');
$htmlElementObject->appendAttribute('class', 'primary', ' ');
echo $htmlBuilder->render($htmlElementObject);

// Output:
// <div class="btn primary">foo</div>

Instances of HtmlElementUniversalAbstract, such as achor, break, button, div, fieldset, fieldset legend, form, headline, image, input, label, list, paragraph, preformated text, select, span, textarea have the following getter-/setter-methodes to access and modify attributes:

getId(), setId($id), getClass(), setClass($class), getStyle(), setStyle($style), getTitle(), setTitle($title), getOnClick(), setOnClick($event), getOnDoubleClick(), setOnDoubleClick($event), getOnMouseDown(), setOnMouseDown($event), getOnMouseUp(), setOnMouseUp($event), getOnMouseOver(), setOnMouseOver($event), getOnMouseMove(), setOnMouseMove($event), getOnMouseOut(), setOnMouseOut($event), getOnKeyPress(), setOnKeyPress($event), getOnKeyDown(), setOnKeyDown($event), getOnKeyUp(), setOnKeyUp($event)

Some html elements also have special getter-/setter-methodes to access and modify attributes. For Example anchor (href, target, name, onblur, onfocus), button (type, name, value, tabindex, disabled, onblur, onfocus), image (src, alt, width, height, loading), meta (name), label (for), form (action, method, target, enctype, autocomplete, onreset, onsubmit), input (type, name, disabled, readonly, onblur, onchange, onfocus).

Nested elements

Nasted html elements can set with the addChildElement() method.

use Naucon\HtmlBuilder\HtmlDiv;
$htmlElementObject = new HtmlDiv();
$htmlElementObject->setClass('level1');

$htmlElementChildObject = new HtmlDiv();
$htmlElementChildObject->setClass('level11');
$htmlElementObject->addChildElement($htmlElementChildObject);

$htmlElementChild2Object = new HtmlDiv('Home');
$htmlElementChild2Object->setClass('level111');

$htmlElementChildObject->addChildElement($htmlElementChild2Object);
echo $htmlBuilder->render($htmlElementObject);

// Output:
// <div class="level1">
// <div class="level11">
// <div class="level111">Home</div>
// </div>
// </div>

Some Html Element with nasted elements by design have a particular method to set options oder item.

Like the select element with options...

$htmlElementObject = new HtmlSelect('foo');
$htmlElementObject->addOption('Ms.', 'MS');
$htmlElementObject->addOption('Mr.', 'MR', true);
echo $htmlBuilder->render($htmlElementObject);

// Output:
// <select name="foo">
// <option value="MS">Ms.</option>
// <option value="MR" selected="selected">Mr.</option>
// </select>';

... or ordered Lists (ol) with list items (li) ...

$htmlElementObject = new HtmlListOrdered();
$htmlElementObject->addItem('foo');
$htmlElementObject->addItem('Bar', 'bar');
echo $htmlBuilder->render($htmlElementObject);

// Output:
// <ol>
// <li>foo</li>
// <li value="bar">Bar</li>
// </ol>

... or unordered Lists (ul) with list items (li) ...

$htmlElementObject = new HtmlListUnordered();
$htmlElementObject->addItem('foo');
$htmlElementObject->addItem('Bar', 'bar');
echo $htmlBuilder->render($htmlElementObject);

// Output:
// <ul>
// <li>foo</li>
// <li value="bar">Bar</li>
// </ul>

... or tables.

use Naucon\HtmlBuilder\HtmlTable;

$htmlTable = new HtmlTable();
$htmlTableHeader = $htmlTable->addHeader();
$htmlTableRow = $htmlTableHeader->addRow();
$htmlTableRow->addHeader('fruit')
    ->addHeader('quantity');

$htmlTableBody = $htmlTable->addBody();
$htmlTableRow = $htmlTableBody->addRow();
$htmlTableRow->addData('apple')
    ->addData('3');

$htmlTableRow = $htmlTableBody->addRow();
$htmlTableRow->addData('banana')
    ->addData('4');

$htmlTableRow = $htmlTableBody->addRow();
$htmlTableRow->addData('orange')
    ->addData('2');

$htmlTableFooter = $htmlTable->addFooter();
$htmlTableRow = $htmlTableFooter->addRow();
$htmlTableRow->addData('total')
    ->addData('9');

echo $htmlBuilder->render($htmlTable);

// Output:
// <table>
//   <thead>
//     <tr>
//       <th>fruit</th>
//       <th>quantity</th>
//     </tr>
//   </thead>
//   <tbody>
//     <tr>
//       <td>apple</td>
//       <td>3</td>
//     </tr>
//     <tr>
//       <td>banana</td>
//       <td>4</td>
//     </tr>
//     <tr>
//       <td>orange</td>
//       <td>2</td>
//     </tr>
//   </tbody>
//   <tfoot>
//     <tr>
//       <td>total</td>
//       <td>9</td>
//     </tr>
//   </tfoot>
// </table>

Render

Html elements can be rendered in the following ways:

With render() the complete html element with his content will be rendered.

$htmlElementObject = new HtmlDiv(new HtmlHeadline('Main headline', 1));
echo $htmlBuilder->render($htmlElementObject);

// Output:
// <div><h1>Main headline</h1></div>

With renderContent() only the content will be rendered.

$htmlElementObject = new HtmlDiv(new HtmlHeadline('Main headline', 1));
echo $htmlBuilder->renderContent($htmlElementObject);

// Output:
// <h1>Main headline</h1>

With renderStartTag() only the start tag of the html element will be rendered.

$htmlElementObject = new HtmlDiv(new HtmlHeadline('Main headline', 1));
echo $htmlBuilder->renderStartTag($htmlElementObject);

// Output:
// <div>

With renderEndTag() only the end tag of the html element will be rendered.

$htmlElementObject = new HtmlDiv(new HtmlHeadline('Main headline', 1));
echo $htmlBuilder->renderEndTag($htmlElementObject);

// Output:
// </div>
