In joomla 3.x implemented delete the data from database using object
this my code not working
function deleteJob()
{
$id = $_REQUEST['id_ud'];
$object = new stdClass();
$object->id = $id;
$resultd =JFactory::getDbo()->deleteObject('#___institute_post_job',$object, 'id');
}
if(isset($_POST['inidelete_job'])) {
deleteJob();
}
please help me?
There is No method for "deleteObject" . if you want to delete operation , you have write query and execute.
There is no object delete just like insertObject,updateObject,...
refer last example for delete:
https://docs.joomla.org/Inserting,_Updating_and_Removing_data_using_JDatabase
JFactory::getDBo() basically call JDatabaseDriver,you can use following methods.

If you are thinking this question is a beginner's question, maybe you are right. But really I was confused.
In my code, I want to know if saving a model is successful or not.
$model = Model::find(1);
$model->attr = $someVale;
$saveStatus = $model->save()
So, I think $saveStatus must show me if the saving is successful or not, But, now, the model is saved in the database while the $saveStatus value is NULL.
I am using Laravel 7;
save() will return a boolean, saved or not saved. So you can either do:
$model = new Model();
$model->attr = $value;
$saved = $model->save();
if(!$saved){
//Do something
}
Or directly save in the if:
if(!$model->save()){
//Do something
}
Please read those documentation from Laravel api section.
https://laravel.com/api/5.8/Illuminate/Database/Eloquent/Model.html#method_getChanges
From here you can get many option to know current object was modified or not.
Also you can check this,
Laravel Eloquent update just if changes have been made
For Create object,
those option can helpful,
You can check the public attribute $exists on your model
if ($model->exists) {
// Model exists in the database
}
You can check for the models id (since that's only available after the record is saved and the newly created id is returned)
if(!$model->id){
App::abort(500, 'Some Error');
}
I am using Laravel Scout with Algolia for populating a datatable and have this intermittent issue where a record in the table after delete will still be visible. It happens when Algolia's index doesn't update quickly enough and the application fetches the data from Algolia prior to it showing as deleted. After refreshing the page and/or updating another record it shows the correct data. Below is my setup - does anyone have any ideas on how to better set this up so any live update will always have the correct data?
public function deleteSelected()
{
$truckings = Trucking::query()->whereKey($this->selected);
$truckings->each(fn ($trucking) => $trucking->delete());
event(new TruckingCreated);
$this->showDeleteModal = false;
$this->notify('You\'ve deleted ' . collect($this->selected)->count() . ' trucking slips.');
$this->getRowsQueryProperty();
$this->selected = [];
}
As you can see I am calling $this->getRowsQueryProperty(); method after deleting records to force it to update - but there are still instances where this will happen.
Below is that method for reference which fetches the data.
public function getRowsQueryProperty()
{
$query = Trucking::search($this->filters['search'],
function (SearchIndex $algolia, string $query, array $options) {
$options['filters'] = $this->algoliaFilters();
return $algolia->search($query, $options);
});
return $this->applySorting($query);
}
Thank you for any help or advice.
It is because you're missing the get call from your query. Using each without get first chunks the results and runs a mass delete query, bypassing model events, thus not deleting indexes.
$truckings = Trucking::query()->whereKey($this->selected)->get();
$truckings->each(fn ($trucking) => $trucking->delete());
I need to get prefix table in magento 2 to join with another table. I try to find on internet but I don't see how to get prefix table in magento 2. Can you help me
You can get the prefix by using the function getTableName() like below :
Always use getTableName with raw queries to fetch the table along with the prefix dynamically
protected $_resource;
public function __construct(
\Magento\Backend\App\Action\Context $context,
\Magento\Framework\App\ResourceConnection $resource
) {
$this->_resource = $resource;
parent::__construct($context);
}
public function execute()
{
$connection = $this->_resource->getConnection();
$tableName = $connection->getTableName('customer_entity'); // It will return "yourtableprefix_customer_entity"
$mapsDeleteQuery = "your raw SQL Query";
$connection->query($mapsDeleteQuery);
}
It seems that there have been some code changes in Magento. So now referring to #Manashvi Birla answer, you need to replace :
$connection->getTableName('customer_entity');
by :
$this->_resource->getTableName('customer_entity');
to be able to get the table prefix.
Just open env.php. You can find env.php file under base_dir/app/etc/env.php
Here you can search keyword table_prefix.
I hope it helps you.
Let me explain about my problem.
I am currently using Laravel 5.0. Here is my structure
Table: bgts, Model: Bgt, Controller: BgtController
Table: bgthistories, Model: BgtHistory
Now I want to do these:
Everytimes creating new item into bgts table, I want to make a copy and insert into bgthistories table. Then, everytimes that record is updated, i'll copy one more version, still insert into bgthistories.
Here is store() method.
public function store(Request $request) {
$bgt = new Bgt();
$history = $this->coppy($bgt);
$uploader = new UploadController('/data/uploads/bgt');
$bgt->name = $request['name'];
$bgt->avatar = $uploader->avatar($request);
$bgt->attachments($uploader->attachments($request));
//dd($bgt);
$bgt->save();
$history->save();
return redirect('bgt');
}
And this is the coping:
public function coppy($bgt) {
$array = $this->$bgt->toArray();
$version = new BgtHistory();
foreach($array as $key => $value) {
$version->$key = $value;
}
return $version;
}
I create migration tables already. Everything is ready. But, when I call
$bgt->save();
$history->save();
It did not work. If I remove $history->save();, it create new record ok. I think the save() method that built-in in Model provided by Laravel is problem. Can anyone tell me how to solve this.
I tried to build the raw query then executed it by DB:statement but it did not work too. Every try to execute anything with DB is failing.
Please research before re-inventing the wheel.

Where and how I am overriding the save method in Joomla 3.0 custom component ?
Current situation:
Custom administrator component.
I have a list view that displays all people stored in table.
Clicking on one entry I get to the detailed view where a form is loaded and it's fields can be edited.
On save, the values are stored in the database. This all works fine.However, ....
When hitting save I wish to modify a field before storing it into the database. How do I override the save function and where? I have been searching this forum and googled quiet a bit to find ways to implement this. Anyone who give me a simple example or point me into the right direction ?
Thanks.
Just adding this for anyone who wants to know the answer to the question itself - this works if you explicitly wish to override the save function. However, look at the actual solution of how to manipulate values!
You override it in the controller, like this:
/**
* save a record (and redirect to main page)
* #return void
*/
function save()
{
$model = $this->getModel('hello');
if ($model->store()) {
$msg = JText::_( 'Greeting Saved!' );
} else {
$msg = JText::_( 'Error Saving Greeting' );
}
// Check the table in so it can be edited.... we are done with it anyway
$link = 'index.php?option=com_hello';
$this->setRedirect($link, $msg);
}
More details here: Joomla Docs - Adding Backend Actions
The prepareTable in the model (as mentioned above) is intended for that (prepare and sanitise the table prior to saving). In case you want to us the ID, though, you should consider using the postSaveHook in the controller:
protected function postSaveHook($model, $validData) {
$item = $model->getItem();
$itemid = $item->get('id');
}
The postSaveHook is called after save is done, thus allowing for newly inserted ID's to be used.
You can use the prepareTable function in the model file (administrator/components/yourComponent/models/yourComponent.php)
protected function prepareTable($table)
{
$table->fieldname = newvalue;
}
