FormRow

The FormRow view helper is used by Form view helper to render each row of a form, but can also be used stand-alone. A form row usually consists of the output produced by the helper specific to an input, plus its label and errors, if any.

FormRow handles different rendering options, having elements wrapped by the <label\> HTML block by default, but also allowing to render them in separate blocks when the element has an id attribute specified, thus preserving browser usability features.

Other options involve label positioning, escaping, toggling errors and using custom partial templates.

Basic Usage

/**
 * inside view template
 *
 * @var \Zend\View\Renderer\PhpRenderer $this
 * @var \Zend\Form\Form $form
 */

// Prepare the form
$form->prepare();

// Render the opening tag
echo $this->form()->openTag($form);

$element = $form->get('some_element');
$element->setLabel('Some Label');

// Render 'some_element' label, input, and errors if any:
echo $this->formRow($element);
// Result: <label><span>Some Label</span><input type="text" name="some_element" value=""></label>

// Altering label position:
echo $this->formRow($element, 'append');
// Result: <label><input type="text" name="some_element" value=""><span>Some Label</span></label>

// Setting the 'id' attribute will result in a separated label rather than a
// wrapping one:
$element->setAttribute('id', 'element_id');
echo $this->formRow($element);
// Result: <label for="element_id">Some Label</label><input type="text" name="some_element" id="element_id" value="">

// Turn off escaping for HTML labels:
$element->setLabel('<abbr title="Completely Automated Public Turing test to tell Computers and Humans Apart">CAPTCHA</abbr>');
$element->setLabelOptions(['disable_html_escape' => true]);
// Result:
// <label>
//   <span>
//       <abbr title="Completely Automated Public Turing test to tell Computers and Humans Apart">CAPTCHA</abbr>
//   </span>
//   <input type="text" name="some_element" value="">
// </label>

// Render the closing tag
echo $this->form()->closeTag();

Escaping

Label content is escaped by default.
