how can i make a database query with extbase to check if a database entry already exist? I know how to do that with php but not with extbase syntax.
I want to add a user to the database. That works. But the user should only be added if the regId doesn't already exist.
This is my code so far:
/**
* action registerDevice
* #param Tx_xxx_Domain_Repository_UserRepository $muserRepository
* #return void
*/
public function registerDeviceAction(){
$userRepository = $this->objectManager->get('Tx_xxx_Domain_Repository_UserRepository');
$user = $this->objectManager->create('Tx_xxx_Domain_Model_User');
$allUser = $this->userRepository->findAll();
if ( isset($_POST["regId"]) && $_GET['os'] ) {
$regDevice = $_POST["regId"];
$regMobileOs = $_GET["os"];
$user->setMobileOs( $regMobileOs );
$user->setFirstName('TEST');
$user->setRegId( $regDevice );
$this->userRepository->add($user);
$persistenceManager = t3lib_div::makeInstance('Tx_Extbase_Persistence_Manager');
$persistenceManager->persistAll();
}
}
Thank you very much! :)
Best regards
Since Extbase 1.1 you can use the Magic Method find(One)ByProperty and countByProperty.
So, without creating a new method you can use something like:
if(!$this->someRepository->countByRegId($regId)) {
// there isnt a object with $regId yet
}

I am attempting to sort an ArrayCollection by a specific field. The ArrayCollection is an array of courses. In the Course entity there is a method called isLive which returns a boolean.
I would like to sort this collection to have the "live" courses at the beginning of the array, so that's the courses that return true from a isLive call.
This is the code I have at present, but the first entry in the $sorted array is a non-live course.
$iterator = $this->courses->getIterator();
$iterator->uasort(function ($a, $b) {
if ($a->isLive() == $b->isLive()) {
return 0;
}
return ($a->isLive() < $b->isLive()) ? -1 : 1;
});
$sorted = new ArrayCollection(iterator_to_array($iterator));
It looks like a good use case for Doctrine Criteria. They allow to filter/sort ArrayCollections, either in memory if the collection is already loaded, either by adding a WHERE / ORDER BY SQL clause next time the collection will be loaded from the database. So that's pretty optimized!
Code should look like something like this, assuming you have a live field behind isLive():
$criteria = Criteria::create()
->orderBy(["live" => Criteria::DESC])
;
$sorted = $this->courses->matching($criteria);
For the entity, do this: add an OrderBy annotation to the property.
/**
* #OneToMany(targetEntity="Course")
* #OrderBy({"live": "ASC"})
*/
private $courses;
I got to a solution with the use of uasort and array_search as below:
/**
* #return ArrayCollection
*/
public function getCoursesSortedByLive(): ArrayCollection
{
$coursesIterator = $this->courses->getIterator();
$sortOrder = [true];
$coursesIterator->uasort(function ($a, $b) use ($sortOrder) {
return array_search($a->isLive(), $sortOrder) - array_search($b->isLive(), $sortOrder);
});
return new ArrayCollection(iterator_to_array($sitesIterator));
}
im quite new in laravel framework, and im from codeigniter.
I would like to add new key and value from database
static function m_get_promotion_banner(){
$query = DB::table("promotion_banner")
->select('promotion_banner_id','promotion_link','about_promotion')
->where('promotion_active','1')
->get();
if($query != null){
foreach ($query as $key => $row){
$query[$key]['promotion_image'] = URL::to('home/image/banner/'.$row['promotion_banner_id']);
}
}
return $query;
}
that code was just changed from codeigniter to laravel, since in codeigniter there are no problem in passing a new key and value in foreach statement
but when i tried it in laravel i got this following error :
Indirect modification of overloaded element of Illuminate\Support\Collection has no effect
at HandleExceptions->handleError(8, 'Indirect modification of overloaded element of Illuminate\Support\Collection has no effect', 'C:\xampp\htdocs\laravel-site\application\app\models\main\Main_home_m.php', 653, array('query' => object(Collection), 'row' => array('promotion_banner_id' => 1, 'promotion_link' => 'http://localhost/deal/home/voucher', 'about_promotion' => ''), 'key' => 0))
please guide me how to fix this
thank you (:
The result of a Laravel query will always be a Collection. To add a property to all the objects in this collection, you can use the map function.
$query = $query->map(function ($object) {
// Add the new property
$object->promotion_image = URL::to('home/image/banner/' . $object->promotion_banner_id);
// Return the new object
return $object;
});
Also, you can get and set the properties using actual object properties and not array keys. This makes the code much more readable in my opinion.
For others who needs a solution you can use jsonserialize method to modify the collection.
Such as:
$data = $data->jsonserialize();
//do your changes here now.
The problem is the get is returning a collection of stdObject
Instead of adding the new field to the result of your query, modify the model of what you are returning.
So, assuming you have a PromotionBanner.php model file in your app directory, edit it and then add these 2 blocks of code:
protected $appends = array('promotionImage');
here you just added the custom field. Now you tell the model how to fill it:
public function getPromotionImageAttribute() {
return (url('home/image/banner/'.$this->promotion_banner_id));
}
Now, you get your banners through your model:
static function m_get_promotion_banner(){
return \App\PromotionBanner::where('promotion_active','1')->get();
}
Now you can access your promotionImage propierty in your result
P.D:
In the case you are NOT using a model... Well, just create the file app\PromotionImage.php:
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
class PromotionImage extends Model
{
protected $appends = array('imageAttribute');
protected $table = 'promotion_banner';
public function getPromotionImageAttribute() {
return (url('home/image/banner/'.$this->promotion_banner_id));
}
/**
* The attributes that are mass assignable.
*
* #var array
*/
protected $fillable = [
'promotion_banner_id','promotion_link','about_promotion','promotion_active'
];
just improving, in case you need to pass data inside the query
$url = 'home/image/banner/';
$query = $query->map(function ($object) use ($url) {
// Add the new property
$object->promotion_image = URL::to( $url . $object->promotion_banner_id);
// Return the new object
return $object;
});
I've been struggling with this all evening, and I'm still not sure what my problem is.
I've used ->get() to actually execute the query, and I've tried by ->toArray() and ->jsonserialize() on the data and it didn't fix the problem.
In the end, the work-around I found was this:
$task = Tasks::where("user_id", $userId)->first()->toArray();
$task = json_decode(json_encode($task), true);
$task["foo"] = "bar";
Using json_encode and then json_decode on it again freed it up from whatever was keeping me from editing it.
That's a hacky work-around at best, but if anyone else just needs to push past this problem and get on with their work, this might solve the problem for you.
I have custom library and need to set limit start for list view records from this library.
Code is as follows:
$limitStart = $input->json->get('limit_start');
$model = JModelLegacy::getInstance('Articles', 'ContentModel', array('ignore_request' => true));
$model->setState("list.limit", $limitStart);
I did this but it's set default value to zero.
Can we override the limit start in joomla.
Thanks in advance.
I think you need to use following method to set the limitstart
$limitStart = 5;
$app = JFactory::getApplication();
$app->setUserState($this->context . '.limitstart', $limitStart);
Yes Can override the limitstart for your own library joomla framework
please flow this way
Open =>joomlaFile/configuration.php/for this code line no "7" default set 20
public $list_limit = '20'
Can you change to your Own PageLimit
public $list_limit = '5'
//simply read this
$config = JFactory::getConfig();
$limitStart = $config->get('list_limit');
you need system plugin to do this. see example for native tags component (the condition is needed to avoid rune code on wrong place )
public function onAfterRoute()
{
$app = JFactory::getApplication();
if ($app->input->getRaw('option') == 'com_tags' && $app->input->getRaw('view') == 'tag') {
$app->set('list_limit', 12);
}
}
I'm trying to insert a file into TYPO3 db through frontend using core functions or FileRepository, exactly into sys_file table.
While investigating I've seen few solutions like,
$storageRepository = \TYPO3\CMS\Core\Utility\GeneralUtility::makeInstance('TYPO3\\CMS\\Core\\Resource\\StorageRepository');
$storage = $storageRepository->findByUid(1);
$fileObject = $storage->addFile('/tmp/myfile', $storage->getRootLevelFolder(), 'newFile');
echo $fileObject->getIdentifier(); // Should output "/newFile"
But I still can't find this addFile() in storageRepository class. Am I missing some thing here?
The line $storageRepository->findByUid(1) return a ResourceStorage Object with the Method addFile().
Here is a Documenttion of this class.
https://typo3.org/api/typo3cms/class_t_y_p_o3_1_1_c_m_s_1_1_core_1_1_resource_1_1_resource_storage.html
#mario Thanks. By the way I've achieved what I planned. Here's what I did..
public function uploadFile($uploadedfile) {
$storage = GeneralUtility::makeInstance('TYPO3\\CMS\\Core\\Resource\\StorageRepository');
$filePath = 'uploads/tx_fileupload/'.$uploadedfile['updata']['name'];
$title = $uploadedfile['updata']['name'];
$size = $uploadedfile['updata']['size'];
// Moving the physical file to destined folder
\TYPO3\CMS\Core\Utility\GeneralUtility::upload_copy_move($uploadedfile['updata']['tmp_name'],$filePath);
// Adding a record in sys_file_storage
$fileObject = $storage->createLocalStorage($uploadedfile['updata']['name'],$uploadedfile['updata']['tmp_name'],$filePath,'');
// Inserting file in sys_file
$repositoryFileObject = \TYPO3\CMS\Core\Resource\ResourceFactory::getInstance()->retrieveFileOrFolderObject($filePath);
return $repositoryFileObject;
}
Now moving onto adding corresponding sys_file_reference record.
In drupal 6 i used to do something like this:
<?php
/*
* CLASS Example
*/
class example {
var $id = NULL;
var $title;
var $body;
.....
// Save
function save() {
$primary_key = ($this->id == NULL ? NULL : 'id');
if (drupal_write_record('mytabble', $this, $primary_key)) {
return TRUE;
} else {
return FALSE;
}
}
}
?>
This worked quite well. But in Drupal 7, the drupal_write_record only takes an array and no longer the object $this. The new db_merge also only takes an array.
Since i want to save the properties of my object to the database, the above code was very handy and generic for all kinds of classes.
Is there an alternative way to write an object to database, or a method to place objectproperties into a an array?
Any help will be appreciated!
Robert
drupal_write_record does take an object or an array. Guess your problem is caused somewhere else.
drupal_write_record($table, &$record, $primary_keys = array())
$record: An object or array representing the record to write, passed in by reference. If inserting a new record, values not provided in $record will be populated in $record and in the database with the default values from the schema, as well as a single serial (auto-increment) field (if present). If updating an existing record, only provided values are updated in the database, and $record is not modified.
More info on drupal_write_record for D7.
