README
A super easy Bootstrap ready HTML form generator for PHP
v2.0.0 has been upgraded for PHP 7.1+ and now has 'Field Transformer' functionality. You can add data transformers to fields to have them convert objects into form data, and vice versa. See the Transformers section of this readme.
Installation
Install via composer
composer require delboy1978uk/form
Usage
Firstly, "use" all the classes you'll need for your form. Then create your form and fields.
<?php use Del\Form\Form; use Del\Form\Field\Text; use Del\Form\Field\CheckBox; use Del\Form\Field\Submit; // Create a form $form = new Form('registration'); // Create a username, email, spamlist checkbox, and submit button. $userName = new Text('username'); $email = new Text('email'); $spamMe = new CheckBox('spam'); $submit = new Submit('submit'); // Set labels $userName->setLabel('User Name'); $email->setLabel('Email Address'); $spamMe->setLabel('Join our (and 3rd parties) email list(s)'); // Add the fields to the form $form->addField($userName) ->addField($email) ->addField($spamMe) ->addField($submit); // Render the form echo $form->render();
Creating Custom Forms
Of course, it's nicer to create your own form than build one up every time, so just create a class and extend
Del\Form\AbstractForm
and add your fields in the init() function:
<?php namespace My\Cool; use Del\Form\AbstractForm; use Del\Form\Field\Text\EmailAddress; use Del\Form\Field\Text\Password; use Del\Form\Field\Submit; class LoginForm extends AbstractForm { public function init() { $email = new EmailAddress('email'); $password = new Password('passord'); $submit = new Submit('submit'); $this->addField($email); $this->addField($password); $this->addField($submit); } }
Then using your form is as simple as:
<?php use My\Cool\LoginForm; $form = new LoginForm('login'); $form->render();
Fitering and validating input
For filtering input, add a Del\Form\Filter\Interface
to your field object. For validating the filtered input, add a
Del\Form\Validator\ValidatorInterface
. Currently there is an adapter for Laminas\Filter and Laminas\Validate
, but feel free to
write an adapter for you favourite library. Setting a required field adds a Del\Form\Validator\NotEmpty
validator.
<?php // A text field, and an adapter for the filters and the validators use Del\Form\Field\Text; use Del\Form\Filter\Adapter\FilterAdapterZf; use Del\Form\Validator\Adapter\ValidatorAdapterZf; // Some sensible default string filters for username/email fields use Laminas\Filter\StripTags; use Laminas\Filter\StringTrim; use Laminas\Filter\StringToLower; // Validation rules use Laminas\Validator\CreditCard;; // Create the field $creditCard = new Text('credit-card'); // Create the filters $stripTags = new FilterAdapterZf(new StripTags()); $trim = new FilterAdapterZf(new StringTrim()); $lowerCase = new FilterAdapterZf(new StringToLower()); // Create the validators $emailAddress = new ValidatorAdapterZf(new CreditCard()); // Add them to the field $creditCard->addFilter($stripTags) ->addFilter($trim) ->addFilter($lowerCase) ->addValidator($emailAddress);
Setting and getting values
Del\Form\FormInterface
has a populate method which takes an array (usually the post data, but not necessarily ;-).
<?php if (isset($_POST['submit'])) { // or ask your request object ;-) $data = $_POST; $form->populate($data); if ($form->isValid()) { $filteredData = $form->getValues(); } }
After populate has been called, if you call Form::render(), it will display any validation error messages.
Field Types
Text
Del\Form\Field\Text
fields are the most basic field, and come with a built in StripTags and StringTrim filter.
Del\Form\Field\Text\EmailAddress
extends Text, and adds an EmailAddress validator for convenience.
Del\Form\Field\Text\Password
is a password field which also extends Text.
<?php use Del\Form\Field\Text; $text = new Text('text'); $text->setLabel('Needed Details'); $text->setRequired(true); $text->setPlaceholder('type some text..'); $text->setValue('Blah');
TextArea
Del\Form\Field\TextArea
fields are pretty much the same as the Text field
<?php use Del\Form\Field\TextArea; $textArea = new TextArea('message');;
Select
Del\Form\Field\Select
needs initialised with setOptions():
<?php use Del\Form\Field\Select; $select = new Select('choose'); $select->setOptions([ 'BK' => 'Burger King', 'McD' => 'McDonalds', 'Q' => 'Quick', ]);
MultiSelect
Del\Form\Field\MultiSelect
also needs initialised with setOptions(), and works in the same way as a Select
field.
Radio
Del\Form|Field\Radio
can be rendered inline (side by side) or not, also needs initialised with setOptions():
<?php use Del\Form\Field\Radio; $radio = new Radio('choose'); $radio->setRenderInline(true); $radio->setOptions([ 'BK' => 'Burger King', 'McD' => 'McDonalds', 'Q' => 'Quick', ]);
Checkbox
Del\Form|Field\Checkbox can be rendered inline or not, also needs initialised with setOptions():
<?php use Del\Form\Field\CheckBox; $check = new CheckBox('choose'); $check->setOptions([ 'BK' => 'Burger King', 'McD' => 'McDonalds', 'Q' => 'Quick', ]);
FileUpload
Del\Form\Field\FileUpload
fields come with a nifty looking Bootstrap compatible renderer, but it uses some javascript.
If you don't want that, just call setRenderer() and pass it a default TextRender class instance. Also, don't forget to set
the encryption type on the form to Form::ENC_TYPE_MULTIPART_FORM_DATA
<?php use Del\Form\Field\FileUpload; $form->setEncType(Form::ENC_TYPE_MULTIPART_FORM_DATA); $fileUpload = new FileUpload('photo'); $fileUpload->setUploadDirectory('/path/to/destination');
Submit`
Del\Form|Field\Submit
doesn't really need much:
<?php use Del\Form\Field\Submit; $submit = new Submit('submit'); $submit->setValue('Send');
Dynamic Forms
You can have for example a radio button with two choices, and each choice can have a separate form relevant to the checked value. For instance, a radio with a choice of food or drink could then display a dynamic form upon clicking the drink option, and the drinks form will display.
<?php $radio = new Radio('choice'); $radio->setLabel('Please choose..'); $radio->setRenderInline(true); $radio->setRequired(true); $radio->setOptions([ 1 => 'Food', 2 => 'Drink', ]); $foodForm = new Form('food'); // This form appears when radio choice 1 is selected $foodRadio = new Radio('foodchoice'); $foodRadio->setLabel('Choose your food.'); $foodRadio->setRequired(true); $foodRadio->setOptions([ 1 => 'Cheeseburger', 2 => 'Pizza', 3 => 'Steak', ]); $foodForm->addField($foodRadio); $radio->addDynamicForm($foodForm, 1); $drinkForm = new Form('drink'); // This form appears when radio choice 2 is selected $drinkRadio = new Radio('drinkchoice'); $drinkRadio->setRequired(true); $drinkRadio->setLabel('Choose your drink.'); $drinkRadio->setOptions([ 1 => 'Beer', 2 => 'Vodka', 3 => 'Whisky', ]); $moreText = new Text('moretext'); $moreText->setLabel('whatever'); $moreText->setPlaceholder('Another text field to fill in'); $drinkForm->addField($drinkRadio); $drinkForm->addField($moreText); $radio->addDynamicForm($drinkForm, 2);
Transformers
You can create an object implementing De\Form\Field\TransformerInterface
to take in input and convert to a form value.
Do the opposite in the output method and return the object representation.
Bone MVC comes with one built in Transformer for DateTime
fields:
<?php $format = 'Y-m-d'; $form = new Form('some-form'); $date = new Text('date'); $date->setTransformer(new DateTimeTransformer($format)); $form->addField($date);
Now the array you populate the form with can contain either the string
or the DateTime
representation.
When getting the values from the form, you pass true to use the transformers:
<?php $values = $form->getValues(); // $values['date'] === '2014-09-18' (for instance) $values = $form->getValues(true); // $values['date'] instanceof DateTime
