FormLabel

The FormLabel view helper is used to render a <label> HTML element and its attributes. If you have a Zend\I18n\Translator\Translator attached, FormLabel will translate the label contents when rendering.

Basic usage

use Zend\Form\Element;

$element = new Element\Text('my-text');
$element->setLabel('Label');
$element->setAttribute('id', 'text-id');
$element->setLabelAttributes(['class' => 'control-label']);

// Within your view...

/**
 * Example #1: Render label in one shot
 */
echo $this->formLabel($element);
// Result: <label class="control-label" for="text-id">Label</label>

echo $this->formLabel($element, $this->formText($element));
// Result: <label class="control-label" for="text-id">Label<input type="text" name="my-text"></label>

echo $this->formLabel($element, $this->formText($element), 'append');
// Result: <label class="control-label" for="text-id"><input type="text" name="my-text">Label</label>

/**
 * Example #2: Render label in separate steps
 */
// Render the opening tag
echo $this->formLabel()->openTag($element);
// Result: <label class="control-label" for="text-id">

// Render the closing tag
echo $this->formLabel()->closeTag();
// Result: </label>

/**
 * Example #3: Render html label after toggling off escape
 */
$element->setLabel('<abbr title="Completely Automated Public Turing test to tell Computers and Humans Apart">CAPTCHA</abbr>');
$element->setLabelOptions(['disable_html_escape' => true]);
echo $this->formLabel($element);
// Result:
// <label class="control-label" for="text-id">
//     <abbr title="Completely Automated Public Turing test to tell Computers and Humans Apart">CAPTCHA</abbr>
// </label>

Escaping

HTML escaping only applies to the Element::$label property, not to the helper $labelContent parameter.

Label translation

See AbstractHelper Translation.

Public methods

The following public methods are in addition to those inherited from the AbstractHelper:

Method signature Description
__invoke(ElementInterface $element = null, string $labelContent = null, string $position = null) : string Render a form label, optionally with content. Always generates a for attribute, as we cannot assume the form input will be provided in the $labelContent. If the $labelContent is null, the helper uses the element's label value. $position is used to indicate where the label element should be rendered, and should be one of FormLabel::APPEND or FormLabel::PREPEND (the default).
openTag(array|ElementInterface $attributesOrElement = null) : string Renders the <label> open tag and attributes. $attributesOrElement should be an array of key/value pairs representing label attributes, or an ElementInterface instance.
closeTag() : string Renders a </label> closing tag.
