Generate quick form on the Frontend based on TCA

2.0.1 2018-04-24 13:56 UTC

GPL-2.0+

• form
• TYPO3 CMS

README

This is a TYPO3 CMS extension which allows to quickly build a form on the Frontend that corresponds to a data type describe by the TCA.

The form can be used with an Extbase but not necessary.

Installation

Installation as "normal" in the Extension Manager.

Configuration

Settings are done by TypoScript in EXT:quick_form/Configuration/TypoScript/setup.txt.

• key "partialExtension": - Tells where to find the Partials. Starting a new project it is encouraged to copy / paste the Partials from EXT:quick_form into your own extension and adjust the HTML markup there. Make sure to respect the path convention. - default "quick_form"
• key "validate" - Configuration for form validation by TypoScript. - default empty

View Helpers

Edit form

There is a View Helper that will read the TCA configuration and will generate the form on the Frontend:

<qf:tca.form type="1" arguments="{_all}" dataType="fe_users"/>

Important to notice, the View Helper will not generate the form tag giving the full flexibility of the action and controller. In other words, the VH must be wrapped by a f:form tag as in the example:

# Regular Extbase Form
<f:form action="update" controller="User" name="user" object="{user}" additionalAttributes="{role: 'form'}">

    <qf:tca.form type="1" arguments="{_all}" dataType="fe_users" validation="tca"/>

</f:form>

Show form (pre-visualisation)

For pre-visualisation needs, the tca.show can be used. It will display the visualisation (read-only) instead of the field for editing.

<f:form action="create" controller="User" name="user" object="{user}" additionalAttributes="{role: 'form'}">

    # tca.show != tca.form
    <qf:tca.show type="1" arguments="{_all}" dataType="fe_users"/>

</f:form>

Flexible Validation

Quick Form will show information on the Frontend whether the field contains validation. This is for now limited to: is required? has error after submit?

It is configured to add a well-known "*" to show the field is required.

To get the validation info, Quick Form has three possible sources that can be configured with attribute "validation". If nothing is configured Quick Form will take the TCA as fallback which has the advantage to keep in sync the Backend and the Frontend.

• tca: check validation against TCA, default
• typoscript: Extbase makes it quite complicated to validate a model having different types. To work around typoscript validation can be used. Configuration must be given in plugin.tx_quickform.validate
• object: use the object provided by context and use reflection to tell what fields are required.
• MyExtension\Domain\Model\Foo: an object is not always available in the context. A model name can be provided.

@todo add more validation output such as string length, email, ...

TCA configuration

In file EXT:sample/Configuration/TCA/tx_sample_domain_model_foo make sure to have a section like:

# Adequate for "flat" structure.
return array(
    'quick_form' => array(
        '1' => 'first_name, last_name, ...',
    ),

TCA configuration can be more complex by accepting nested structure:

# Adequate for "nested" structure which contains field-set and other containers.
return array(
    'quick_form' => array(
        '1' => array(
            'partial' => 'Form/FieldSet',
            'items' => array(
                'first_name',
                'last_name',
                array(
                    'partial' => 'Form/Submit',
                ),
            ),
        ),
    ),

Quick Form also accepts a syntax with object that is a bit more concise than array and that is convenient when working with an IDE which auto-complete parameters:

# Usage of a Quick Form Component
return array(
    'quick_form' => array(
        '1' => array(
            'partial' => 'Form/FieldSet',
            'items' => array(
                'first_name',
                'last_name',
                new \Vanilla\QuickForm\Component\SubmitComponent()
            ),
        ),
    ),

Use "external" Partials

Partials within EXT:quick_start are taken as defaults. However, it is possible to use "external" Partials located in another extension:

new \Vanilla\QuickForm\Component\GenericComponent('Form/Foo', array('property' => 'propertyName', 'label' => 'fieldName'), 'foo'),

• The first parameter corresponds to the Partial Name
• The second to the arguments
• The third is the extension where the Partials come from

Override label

In case the Frontend label must be different than in the BE, use option alternative_label in the arguments of the Form Component:

array(
    'alternative_label' => 'LLL:EXT:bobst_forms/Resources/Private/Language/locallang.xlf:privacy_satement_label',
)

Quick Form Components

A list of all components that can be displayed in a Quick Form. Some of them are a bit more complex to set-up as they need a good TCA configuration along with a correct Extbase code. For those ones, there is code example given below.

• Checkbox
• CheckboxGroup (with example)
• DatePicker (with example)
• FieldSet
• FileUpload (with example)
• Hidden
• MultiChoices (with example)
• MultiSelect
• Navigation
• NavigationFirst
• NavigationLast
• NumberField
• RadioButtons
• Select
• Separator
• Submit
• TabPanel
• Text
• TextArea
• TextField
• Todo (component for just showing some temporary message on the Frontend)

CheckboxGroup

array(
    'partial' => 'Form/CheckboxGroup',
    'arguments' => array('label' => 'wheels_or_tracks'),
    'items' => array(
        'operational_data_wheels',
        'operational_data_tracks',
    ),
),

Checkbox

If checkbox must be specially configured:

new \Vanilla\QuickForm\Component\CheckboxComponent(
    'hasNewsletterSubscription',
    'has_newsletter_subscription',
    array('group_label' => 'Newsletter')
),

TCA configuration

:

'operational_data_wheels' => array(
    'exclude' => 0,
    'label' => 'LLL:EXT:ext/Resources/Private/Language/locallang_db.xml:tx_foo_domain_model_foo.operational_data_wheels',
    'config' => array(
        'type' => 'check',
        'default' => '0'
    ),
),
'operational_data_tracks' => array(
    'exclude' => 0,
    'label' => 'LLL:EXT:ext/Resources/Private/Language/locallang_db.xml:tx_foo_domain_model_foo.operational_data_tracks',
    'config' => array(
        'type' => 'check',
        'default' => '0'
    ),
),

Extbase code

/**
 * @var int
 * @validate Integer
 */
protected $operationalDataWheels = 0;

/**
 * @var int
 * @validate Integer
 */
protected $operationalDataTracks = 0;

DatePicker

:

Some more JavaScript is required here. To be found a jQuery plugin for Bootstrap available in this repository in branch "bs3" as of this writing. https://github.com/eternicode/bootstrap-datepicker/tree/bs3

Honey Pot

In TCA:

new \Vanilla\QuickForm\Component\HoneyPotComponent(),

In Extbase controller:

/**
 * @return void
 * @validate $request \Vanilla\QuickForm\Validator\HoneyPotValidator
 * @param \Vendor\Extension\Domain\Model\Foo $foo
 */
public function createAction(Foo $foo = NULL) {


}

TCA configuration

'available_on_market_from' => array(
    'exclude' => 0,
    'label' => 'LLL:EXT:ext/Resources/Private/Language/locallang_db.xml:tx_foo_domain_model_foo.available_on_market_from',
    'config' => array(
        'type' => 'input',
        'size' => 12,
        'max' => 20,
        'eval' => 'date',
        'default' => '0'
    )
),

Extbase code

/**
 * @var \DateTime
 */
protected $availableOnMarketFrom;

Multi Choice

new \Vanilla\QuickForm\Component\MultiChoicesComponent('protectionLevel'),

TCA configuration

'some_field' => array(
    'exclude' => 0,
    'label' => 'LLL:EXT:ext/Resources/Private/Language/locallang_db.xml:tx_foo_domain_model_foo.some_field',
    'config' => array(
        'type' => 'select',
        'items' => array(
            array('', ''),
            array('LLL:EXT:ext/Resources/Private/Language/locallang_db.xml:tx_foo_domain_model_foo.some_field.label_1', '1'),
            array('LLL:EXT:ext/Resources/Private/Language/locallang_db.xml:tx_foo_domain_model_foo.some_field.label_2', '2'),
        ),
        'size' => 4,
        'maxitems' => 10,
        'eval' => ''
    ),
),

Extbase code

Property:

/**
 * @var string
 */
protected $someField;

Beware, a special array-to-string converter must be defined in the Controller in order to convert the multi-choice to a CSV chain:

/**
 * Initialize object
 */
public function initializeAction() {

    // Configure property mapping.
    if ($this->arguments->hasArgument('objectName')) {

        /** @var \Vanilla\QuickForm\TypeConverter\ArrayToStringConverter $typeConverter */
        $typeConverter = $this->objectManager->get('Vanilla\QuickForm\TypeConverter\ArrayToStringConverter');

        $this->arguments->getArgument('request')
            ->getPropertyMappingConfiguration()
            ->forProperty('someField')
            ->setTypeConverter($typeConverter);
    }
}

File Upload

Suggested EXT:media_upload to use the file upload API in your Extbase controller.

new \Vanilla\QuickForm\Component\FileUploadComponent('logo'),

Media Upload

Require EXT:media_upload which provides HTML5 file upload widget.

new \Vanilla\QuickForm\Component\MediaUploadComponent('logo'),

TCA configuration

'logo' => array(
    'exclude' => 0,
    'label' => 'LLL:EXT:ext/Resources/Private/Language/locallang_db.xml:tx_ext_domain_model_organisation.logo',
    'config' => \TYPO3\CMS\Core\Utility\ExtensionManagementUtility::getFileFieldTCAConfig(
            'logo',
            array(
                'appearance' => array(
                    'createNewRelationLinkTitle' => 'LLL:EXT:cms/locallang_ttc.xlf:images.addFileReference'
                ),
                'minitems' => 0,
                'maxitems' => 1,
            ),
            $GLOBALS['TYPO3_CONF_VARS']['GFX']['imagefile_ext']
    ),
),

Extbase code

Property:

/**
 * @var \TYPO3\CMS\Extbase\Persistence\ObjectStorage<\TYPO3\CMS\Extbase\Domain\Model\FileReference>
 */
protected $logo;

Accessor:

/**
 * @return \TYPO3\CMS\Extbase\Persistence\ObjectStorage<\TYPO3\CMS\Extbase\Domain\Model\FileReference>
 */
public function getLogo() {
    return $this->logo;
}

/**
 * @param \TYPO3\CMS\Extbase\Persistence\ObjectStorage<\TYPO3\CMS\Extbase\Domain\Model\FileReference> $logo
 */
public function setLogo($logo) {
    $this->logo = $logo;
}

/**
 * @param \TYPO3\CMS\Extbase\Persistence\ObjectStorage $logo
 * @return void
 */
public function addLogo(ObjectStorage $logo) {
    $this->logo->attach($logo);
}

/**
 * @param \TYPO3\CMS\Extbase\Persistence\ObjectStorage $logo
 * @return void
 */
public function removeLogo(ObjectStorage $logo) {
    $this->logo->detach($logo);
}
