class Form
Helper functions for outputting form elements.
Wraps form fields (e.g. from Fb) with additional HTML.
Most wrapping will done using the __callStatic method which actually just calls Form::fieldAuto.
That method uses reflection to look for a custom docblock tag, @wrap-in-fieldset.
If that docblock tag is found, the field is wrapped in Form::fieldFieldset
If that docblock tag is not found (the most common case), the field is wrapped in Form::fieldPlain
If the field being wrapped isn't in the Fb helper, the methods fieldAuto, fieldPlain, and fieldFieldset
can be invoked directly.
The outermost wrapper DIV around the field has a class of "field-element".
Additional classes are also added:
- The method and class name, in the format 'field-element--id-<name>'
- If an "id" attribute is set, in the format 'field-element--id-<id>'
- If the field is required, 'field-element--required'
- If the field is disabled, 'field-element--disabled'
- If the field has an error, 'field-element--error'
- One or more custom classes can be specified using the attribute "-wrapper-class".
Each (array or space separated) class is prefixed with 'field-element--' ExampleForm::setData($data);
Form::setErrors($errors);
Form::nextFieldDetails('First name', true);
echo Form::text('first_name');
Form::nextFieldDetails('Email', true, 'Please enter your email address');
echo Form::email('email', [], ['-wrapper-class' => 'small']);
Form::nextFieldDetails('Phone', false, 'Enter a phone number using the unique UI');
echo Form::fieldPlain('SproutModules\Someone\CustomModule\Helpers\FbHack::phone', 'phone', [], []);Extending this class<?php
