TYPO3 fluid selectbox viewhelper.

In the below example, the selectbox options are coming from locallang.

‘hotelclass’ => array(
‘exclude’ => 1,
‘label’ => ‘LLL:EXT:myext/Resources/Private/Language/locallang_db.xlf:tx_myext_domain_model_hotels.hotelclass’,
‘config’ => array(
‘type’ => ‘select’,
‘items’ => array(
array(‘LLL:EXT:myext/Resources/Private/Language/locallang_db.xlf:tx_myext_domain_model_hotels.hotelclass.2star’, ‘2’),
array(‘LLL:EXT:myext/Resources/Private/Language/locallang_db.xlf:tx_myext_domain_model_hotels.hotelclass.3star’, ‘3’),
array(‘LLL:EXT:myext/Resources/Private/Language/locallang_db.xlf:tx_myext_domain_model_hotels.hotelclass.5star’, ‘5’),
array(‘LLL:EXT:myext/Resources/Private/Language/locallang_db.xlf:tx_myext_domain_model_hotels.hotelclass.7star’, ‘7’),
),
‘size’ => 1,
‘maxitems’ => 1,
‘eval’ => ”
),
)

To display this select box in FE from, we can use the custom view helper.

To use the viewhelpler follow the following steps.

1. Create the file

myext/Classes/viewHelpers/TcaOptionsViewHelper.php

2. Add the below code

<?php
namespace TYPO3\Myext\ViewHelpers;

class TcaOptionsViewHelper extends \TYPO3\CMS\Fluid\Core\ViewHelper\AbstractViewHelper {

/**
* local cache for dataMaps
* @var array
*/
protected $dataMaps = array();

/**
* @var \TYPO3\CMS\Extbase\Persistence\Generic\Mapper\DataMapper
* @inject
*/
protected $dataMapper;

/**
* objectManager
*
* @var \TYPO3\CMS\Extbase\Object\ObjectManager
* @inject
*/
protected $objectManager;

/**
* Is returning select values for a property or propertyPath of a given object or className
* @param mixed $subject The object or className the property belongs to
* @param string $property The property itself
* @return array The select options as array
*/
public function render($subject = NULL, $property = ”) {
if (!is_object($subject) && is_string($subject) && class_exists($subject)) {
$subject= $this->objectManager->get($subject);
}
return self::getSelectOptions($property, $subject);
}

/**
* Is resolving the select values for a property or propertyPath of a given object or className
* @param string $propertyPath The property itself
* @param object $subject The object or className the property belongs to
* @return array The select options as array
*/
private function getSelectOptions($propertyPath, $subject) {
$selectOptions = array();

if (is_object($subject)) {
$propertyPathSegments = \TYPO3\CMS\Core\Utility\GeneralUtility::trimExplode(‘.’, $propertyPath);
$object = clone($subject);
$propertyName = $propertyPath;

// resolve a property path
if (count($propertyPathSegments) > 1) {
foreach($propertyPathSegments as $key => $propertyName) {
$propertyType = $this->dataMapper->getType(get_class($tempObject), $propertyName);
if (strpos($propertyType,’_’)) {
$object = $this->objectManager->create($propertyType);
} else {
break;
}
}
}

$dataMap = self::getDataMap($object);

if ($dataMap == NULL || !$dataMap->isPersistableProperty($propertyName)) {
return $selectOptions;
}

$tableName = $this->dataMapper->convertClassNameToTableName(get_class($object));
$columnName = $dataMap->getColumnMap($propertyName)->getColumnName();

// only convert select items which do not have a DB relation
$columnConfig = $GLOBALS[‘TCA’][$tableName][‘columns’][$columnName][‘config’];
if ($columnConfig[‘type’] == ‘select’ && count($columnConfig[‘items’]) && !$columnConfig[‘foreign_table’]) {
foreach ($columnConfig[‘items’] as $option) {
$selectOptions[$option[1]] = \TYPO3\CMS\Extbase\Utility\LocalizationUtility::translate($option[0], $this->controllerContext->getRequest()->getControllerExtensionName());
}
}
}
return $selectOptions;
}

/**
* Resolve the dataMap for the given object
* @param object $object The domain object to get the dataMap for
* @return Tx_Extbase_Persistence_Mapper_DataMap
*/
private function getDataMap($object) {
$class = is_object($object) ? get_class($object) : $object;
if (!isset($this->dataMaps[$class])) {
$this->dataMaps[$class] = $this->dataMapper->getDataMap($class);
}
return $this->dataMaps[$class];
}
}
?>

3. Add the below lines in fluid template, that is intended to show FE form

{namespace custom=TYPO3\Myext\ViewHelpers}

<f:form.select property=”hotelclass” options=”{custom:TcaOptions(property:’hotelclass’,subject:’TYPO3\\Myext\\Domain\\Model\\Hotels’)}” />

4. The output source will be like this.

<select name=”tx_myext_hotels[hotels][hotelclass]”>
<option value=”2″>2 Star</option>
<option value=”3″>3 Star</option>
<option value=”5″>5 Star</option>
<option value=”7″>7 Star</option>
</select>

TYPO3 Extbase custom viewhelper.

As the name suggest, viewhelper helps to modify the view/output of a fluid template.

Here I am showing how to write a viewhelper. This simple viewhelper returns “Yes” if “1” is passed and else “No”.

1. Create the following file.

myExt/Classes/ViewHelpers/YesnoViewHelper.php

2. Write code in that file

<?php
namespace Vendor\Myext\ViewHelpers;

class YesnoViewHelper extends \TYPO3\CMS\Fluid\Core\ViewHelper\AbstractViewHelper {

/**
* @param integer $myvalue
*/
public function render($myvalue) {
$content = ”;
if($myvalue == 1) {
$content = ‘Yes’;
} else {
$content = ‘No’;
}
return $content;
}
}

?>

3. In fluid template use it like below

{namespace custom=Vendor\Myext\ViewHelpers}

<custom:yesno myvalue=”{value}” />

 

TYPO3 FAL (file abstraction layer) in Extbase/Fluid extension

Recently I came across to implement extbase plugin having multiple file upload FE form.

My Typo3 version was 6.1
The extension was created using Extension Builder

File ext_tables.sql

CREATE TABLE tx_clientside_domain_model_orderitems (
:
files int(11) unsigned DEFAULT ‘0’ NOT NULL,
:

);

File Configuration/TCA/OrderItems.php

$TCA[‘tx_clientside_domain_model_orderitems’] = array(
//…… removed code

‘files’ => array(
‘exclude’ => 1,
‘label’ => ‘Files’,
‘config’ => \TYPO3\CMS\Core\Utility\ExtensionManagementUtility::getFileFieldTCAConfig(‘files’, array(
‘appearance’ => array(
‘createNewRelationLinkTitle’ => ‘LLL:EXT:cms/locallang_ttc.xlf:images.addFileReference’
),
), $GLOBALS[‘TYPO3_CONF_VARS’][‘GFX’][‘imagefile_ext’]),
),

//…..

);

File Classes/Domain/Model/OrderItems.php

class OrderItems extends \TYPO3\CMS\Extbase\DomainObject\AbstractEntity {

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

/**
* __construct
*
* @return AbstractObject
*/
public function __construct() {
$this->files = new \TYPO3\CMS\Extbase\Persistence\ObjectStorage();
}
/**
* Returns the files
*
* @return \TYPO3\CMS\Extbase\Persistence\ObjectStorage
*/
public function getFiles() {
return $this->files;
}

}

I have not used function setFiles here.

File Classes/Controller/OrderItemsController.php

class OrderItemsController extends \TYPO3\CMS\Extbase\Mvc\Controller\ActionController {

/**
* orderItemsRepository
*
* @var \TYPO3\Clientside\Domain\Repository\OrderItemsRepository
* @inject
*/
protected $orderItemsRepository;

/**
* action create
*
* @param \TYPO3\Clientside\Domain\Model\OrderItems $newOrderItems
* @dontvalidate $newOrderItems
* @return void
*/
public function createAction(\TYPO3\Clientside\Domain\Model\OrderItems $newOrderItems) {

$this->orderItemsRepository->add($newOrderItems);

$persistenceManager = \TYPO3\CMS\Core\Utility\GeneralUtility::makeInstance(‘Tx_Extbase_Persistence_Manager’);
$persistenceManager->persistAll();
$uidNew = $newOrderItems->getUid();

if ($_FILES[‘tx_clientside_orderitems’]) {
for ($i = 0; $i < count($_FILES[‘tx_clientside_orderitems’][‘name’][‘myfiles’]); $i++) {
$file = array();
$file[‘name’] = $_FILES[‘tx_clientside_orderitems’][‘name’][‘myfiles’][$i];
$file[‘type’] = $_FILES[‘tx_clientside_orderitems’][‘type’][‘myfiles’][$i];
$file[‘tmp_name’] = $_FILES[‘tx_clientside_orderitems’][‘tmp_name’][‘myfiles’][$i];
$file[‘size’] = $_FILES[‘tx_clientside_orderitems’][‘size’][‘myfiles’][$i];
if ($file[‘name’]) {
$files = $this->uploadFile($file[‘name’], $file[‘type’], $file[‘tmp_name’], $file[‘size’]);
$sysFileCreate = $this->orderItemsRepository->myFileOperationsFal($files, $file[‘type’], $file[‘size’], $uidNew);
}
}
}

$this->flashMessageContainer->add(‘Your new OrderItems was created.’);
$this->redirect(‘list’);
}

protected function uploadFile($name, $type, $temp, $size) {
if($size > 0) {
$basicFileFunctions = \TYPO3\CMS\Core\Utility\GeneralUtility::makeInstance(‘t3lib_basicFileFunctions’);

$name = $basicFileFunctions->cleanFileName($name);
$uploadPath = $basicFileFunctions->cleanDirectoryName(‘fileadmin/user_upload/’);
$uniqueFileName = $basicFileFunctions->getUniqueName($name, $uploadPath);
$fileStored = move_uploaded_file($temp, $uniqueFileName);

$returnValue = basename($uniqueFileName);
}

return $returnValue;
}

}

 

File Classes/Romain/Repository/OrderItemsRepository.php

class OrderItemsRepository extends \TYPO3\CMS\Extbase\Persistence\Repository {

public function myFileOperationsFal($filename, $filetype, $filesize, $uidNew){

$newSysFields = array(
‘pid’ => 0,
‘identifier’ =>’/user_upload/’.$filename,
‘mime_type’ => $filetype,
‘name’ => $filename,
‘size’ => $filesize,
‘storage’ => 1,
‘crdate’ => $GLOBALS[‘EXEC_TIME’],
‘tstamp’ => $GLOBALS[‘EXEC_TIME’]
);

$newSysRes = $GLOBALS[‘TYPO3_DB’]->exec_INSERTquery(‘sys_file’, $newSysFields);

$uid_local = $GLOBALS[‘TYPO3_DB’]->sql_insert_id($newSysRes);
$newRefFields = array(
‘pid’ => 88,
‘tablenames’ => ‘tx_clientside_domain_model_orderitems’,
‘uid_foreign’ => $uidNew,
‘uid_local’ => $uid_local,
‘table_local’ => ‘sys_file’,
‘fieldname’ => ‘files’,
‘crdate’ => $GLOBALS[‘EXEC_TIME’],
‘tstamp’ => $GLOBALS[‘EXEC_TIME’]
);

$GLOBALS[‘TYPO3_DB’]->exec_INSERTquery(‘sys_file_reference’, $newRefFields);
}

}

Here I am writing custom File operation function, that creates new entry in table sys_file and mm relation to table sys_file_reference.
I have searched google for any other good way, without success 🙁

Suggestions are welcome 🙂

File Resources/Private/Templates/Root/New.html

<f:form action=”create” enctype=”multipart/form-data” name=”newOrderItems” object=”{newOrderItems}” >
<input name=”tx_clientside_orderitems[myfiles][]” type=”file” /><br />
<input name=”tx_clientside_orderitems[myfiles][]” type=”file” /><br />
<f:form.submit value=”Create new” /></f:form>

 

Here is how to dispaly that images in frontend

File Resources/Private/Templates/Root/Show.html

<f:for each=”{orderItems.files}” as=”file”>
<f:image src=”{file.uid}” alt=”” width=’101′ height=”67″ treatIdAsReference=”1″/>
</f:for>
