I'm stuck with the following problem:
I have a class CartItem. I want to store array of objects of CartItem in session (actually i'm implementing a shopping cart).
class CartItem extends AppModel{
var $name = "CartItem";
var $useTable = false;
}
I tried this:
function addToCart(){
$this->loadModel("Cart");
$this->layout = false;
$this->render(false);
$cart = array();
$tempcart = unserialize($this->Session->read("cart"));
if(isset($tempcart)){
$cart = $tempcart;
}
$productId = $this->request->data("id");
if(!$this->existsInCart($cart, $productId)){
$cartItem = new Cart();
$cartItem->productId = $productId;
$cartItem->createdAt = date();
$cart[] = $cartItem;
$this->Session->write("cart", serialize($cart));
echo "added";
}
else
echo "duplicate";
}
I think I'm writing these lines wrong:
$tempcart = unserialize($this->Session->read("cart"));
$this->Session->write("cart", serialize($cart));
as I'm not getting data from the session.
You are trying to add the whole Cart object to the session.
You should just add an array, like
$cart[] = array(
'productId' => $productId,
'createdAt' => date('Y-m-d H:i:s')
);
If you need to add an object to a session, you can use __sleep and __wakeup magic functions but I think in this case it's better to just add only the product id and date to the session.

Hi i am using sopping cart in laravel 5.8. I want to access the array to be able to store the order in the database. I was able to access the data in the session cart. But to the part of options -> marca y medida. Also I do not know how to bring the total cart.
My controller is as follows
public function transferencia(Request $request)
{
$cart = Session::get('cart');
foreach ($cart as $key => $order) {
$data = json_decode($order, true);
foreach($data as $item){
$opt = new Order;
$opt->id_cliente = $request->input('idusuario');
$opt->fecha = date('j/n/Y');
$opt->cliente = $request->input('persona');
$opt->dni = $request->input('dni');
$opt->producto = $item['name'];
$opt->medida = 'medida'; //how to access this data
$opt->marca = $item['marca']; //how to access this data
$opt->precio = $item['price'];
$opt->cantidad = $item['qty'];
$opt->total = 'total';
$opt->factura = 'factura';
$opt->idpedido = 'idpedido';
$opt->save();
}
}
//dd($item);
//print_r($cont);
}
I am currently working with magento 2.2.1 and I am having a weird problem. I am trying to get a set of data from database and display it on admin grid. I want to take records for a specific agent ID so i have a variable that has the value of the agent id. When i pass this variable as parameter to$this->collection->getSelect()->where('agent_id = ?', $this->givenAgentId); it wont display anything but if i replace $this->givenAgentId with it's value, for example with 4, it works perfectly!
This is my class:
<?php
namespace vendor\plugin\Ui\Component\Listing\DataProviders\Atisstats\Coupons;
use \vendor\plugin\Model\ResourceModel\Coupons\CollectionFactory;
use \Magento\Framework\Registry;
class Listing extends \Magento\Ui\DataProvider\AbstractDataProvider {
protected $_registry;
protected $givenAgentId = 0;
public function __construct(
Registry $registry,
$name,
$primaryFieldName,
$requestFieldName,
CollectionFactory $collectionFactory,
array $meta = [],
array $data = []
) {
parent::__construct($name, $primaryFieldName, $requestFieldName, $meta, $data);
$this->_registry = $registry;
$objectManager = \Magento\Framework\App\ObjectManager::getInstance();
$resource = $objectManager->get('\Magento\Framework\App\ResourceConnection');
$connection = $resource->getConnection();
$select = $connection->select()
->from(
['amasty_perm_dealer'],
['user_id']
);
$data = $connection->fetchAll($select);
foreach ($data as $dealerId) {
if ($dealerId['user_id'] == $this->_registry->registry('admin_session_id')) {
$this->givenAgentId = intval($this->_registry->registry('admin_session_id'));
}
}
if ($this->givenAgentId != 0) {
$this->collection->getSelect()->where('agent_id = ?', $this->givenAgentId);
} else {
$this->collection = $collectionFactory->create();
}
}
}
I have stuck here for hours!
I fixed this problem! First of all it was Registry class causing the problem so I used
$objectManager = \Magento\Framework\App\ObjectManager::getInstance();
$resourceUserId = $objectManager->get('\Magento\Backend\Model\Auth\Session');
to get the user id from session and used it below to check the user! For some reason the registry object was modifying the variable holding the current users id!
I post the answer just in case someone get stuck with this kind of problem !
my question is about how to split this code. I have a registration form and it's saving function looks like this:
public function store(EntityRequestCreate $request)
{
$geoloc = new Geoloc;
$geoloc->lat = $request->input('lat');
$geoloc->lng = $request->input('lng');
$geoloc->slug = $request->input('name');
$geoloc->save();
$user_id = Auth::id();
$entity = new Entity;
$entity->name = $request->input('name');
$entity->type = $request->input('type');
$entity->email = $request->input('email');
$entity->tags = $request->input('tags');
$entity->_geoloc()->associate($geoloc);
$entity->save();
$entity_id = $entity->id;
$address = new Address;
$address->building_name = $request->input('building_name');
$address->address = $request->input('address');
$address->town = $request->input('town');
$address->postcode = $request->input('postcode');
$address->telephone = $request->input('telephone');
$address->entity_id = $entity_id;
$address->save();
$role = User::find($user_id);
$role->role = "2";
$role->save();
DB::table('entity_user')->insert(array('entity_id' => $entity_id, 'user_id' => $user_id));
$result = $geoloc->save();
$result2 = $entity->save();
$result3 = $address->save();
$result4 = $role->save();
if ($result && $result2 && $result3 && $result4) {
$data = $entity_id;
}
else {
$data = 'error';
}
return redirect('profile/entity');
}
As you see, it has a custom request and it is saving to 3 models, that way my controller code is far too long (having many other functions etc) Instead I want to move this code to a model, as my model so far has only relationships defined in it. However I don't exactly know how to call a model from controller, do I have to call it or it will do it automatically? Any other ideas on how to split the code?
You could use the models create method to make this code shorter and more readable.
For example:
$geoloc = Geoloc::create(
$request->only(['lat', 'lng', 'name'])
);
$entity = Entity::create(
$request->only(['name', 'type', 'email', 'tags])
);
$entity->_geoloc()->associate($geoloc);
$address = Address::create([
array_merge(
['entity_id' => $entity->id],
$request->only(['building_address', 'address', 'town'])
)
])
...
The create method will create an object from a given associated array. The only method on the request object will return an associated array with only the fields for the given keys.
I have a function that runs raw SQL queries to our database in Magento. What the function does is changes the customer's default credit card to a value passed to the function. My question is how would I rewrite the function utilizing Magento models. The current function works, but we'd rather have it not be directly interfacing with SQL.
Here is the function:
public function setDefaultPayment($value)
{
$customerId = $this->_getSession()->getCustomer()->getId();
$write = Mage::getSingleton('core/resource')->getConnection('core_write');
$read = $write->query("SELECT entity_type_id FROM eav_entity_type WHERE entity_type_code='customer'");
$row = $read->fetch();
$entity_type_id = $row['entity_type_id'];
$read = $write->query("SELECT attribute_id FROM eav_attribute WHERE attribute_code='default_payment' AND entity_type_id = $entity_type_id");
$row = $read->fetch();
$attribute_id = $row['attribute_id'];
$read = $write->query("SELECT * FROM customer_entity_int WHERE entity_type_id='$entity_type_id' AND attribute_id='$attribute_id' AND entity_id='$customerId'");
if ($row = $read->fetch()) {
$write->update(
'customer_entity_int',
array('value' => $value),
"entity_type_id='$entity_type_id' AND attribute_id='$attribute_id' AND entity_id='$customerId'"
);
} else {
$write->insert(
'customer_entity_int',
array(
'entity_type_id' => $entity_type_id,
'attribute_id' => $attribute_id,
'entity_id' => $customerId,
'value' => $value
)
);
}
}
If I read you code right, you want to update the customer attribute default_payment with a value given.
For that you need to:
Load the customer by id
Set the new value for the customer attribute default_payment
Save the customer
public function setDefaultPayment($value)
{
$customerId = $this->_getSession()->getCustomer()->getId();
$write = Mage::getSingleton('core/resource')->getConnection('core_write');
$customer = Mage::getModel('customer/customer')->load($customerId);
$oldValue = $customer->getDefaultPayment(); // optional, just for checking
$customer->setDefaultPayment($value);
$customer->save();
}
I am using this tutorial on adding new EAV Model in Magento:
http://inchoo.net/ecommerce/magento/creating-an-eav-based-models-in-magento/
Everything works fine except all my attributes are saving with "store_id = 0" when I do this part of code:
$phonebookUser = Mage::getModel('inchoo_phonebook/user');
$phonebookUser->setFristname('John');
$phonebookUser->save();
I am wondering is there any clear way to set store ID on save EAV Entity Attributes.
Thanks.
You can only set values for a specific store only after you added the values for store id 0.
Here is an example.
//create default values
$phonebookUser = Mage::getModel('inchoo_phonebook/user');
$phonebookUser->setFristname('John');
$phonebookUser->save();
//remember the id of the entity just created
$id = $phonebookUser->getId();
//update the name for store id 1
$phonebookUser = Mage::getModel('inchoo_phonebook/user')
->setStoreId(1)
->load($id); //load the entity for a store id.
$phonebookUser->setFristname('Jack'); //change the name
$phonebookUser->save(); //save
I have override the functions in my resource model to work with store_id and it is worked for me but I suggest that this is not the best solution.
protected function _saveAttribute($object, $attribute, $value)
{
$table = $attribute->getBackend()->getTable();
if (!isset($this->_attributeValuesToSave[$table])) {
$this->_attributeValuesToSave[$table] = array();
}
$entityIdField = $attribute->getBackend()->getEntityIdField();
$data = array(
'entity_type_id' => $object->getEntityTypeId(),
$entityIdField => $object->getId(),
'attribute_id' => $attribute->getId(),
'store_id' => $object->getStoreId(), //added this
'value' => $this->_prepareValueForSave($value, $attribute)
);
$this->_attributeValuesToSave[$table][] = $data;
return $this;
}
protected function _getLoadAttributesSelect($object, $table)
{
$select = $this->_getReadAdapter()->select()
->from($table, array())
->where($this->getEntityIdField() . ' =?', $object->getId())
->where('store_id in (?)', array($object->getStoreId(), 0)); //added this
return $select;
}
also I have added this code to the constructor of my entity model:
if (Mage::app()->getStore()->isAdmin()) {
$this->setStoreId(Mage::app()->getRequest()->getParam('store', 0));
}
else{
$this->setStoreId(Mage::app()->getStore()->getId());
}
Override the _getDefaultAttributes() method in your resource model like this:
protected function _getDefaultAttributes()
{
$attributes = parent::_getDefaultAttributes();
$attributes[] = "store_id";
return $attributes;
}
This should work if you have only one value for store_id per your model's entity.
