Ny array looks something like this:
Illuminate\Database\Eloquent\Collection {#2052 ▼
#items: array:3 [▼
0 => App\Models\NewsMeta {#2089 ▶}
1 => App\Models\NewsMeta {#2090 ▶}
2 => App\Models\NewsMeta {#2091 ▶}
]
}
If I open up the array 2:
#original: array:7 [▼
"id" => 17
"post_id" => 240231
"news_tag_id" => 5
"meta_name" => "_thumbnail_id"
"meta_value" => "240232"
"created_at" => "2020-08-06 22:34:06"
"updated_at" => "2020-08-06 22:34:06"
]
Now, I looking to get value "240232" given that I've 240231.
How do I search inside array of the object?
Something like: where post_id is 240231 get ts meta_value.
FYI: It's not eloquent or DB query.
Something like this should work:
$postId = 240231;
$metaValue = null;
foreach ($collection as $model) {
if ($model->post_id == $postId) {
$metaValue = $model->meta_value;
break;
}
}
echo $metaValue;
You could also use the collection's seach method:
$postId = 240231;
$metaValue = $collection->search(static function($model, $key) use($postId) {
if ($model->post_id == $postId) {
return $model->meta_value;
}
});
echo $metaValue;
You can use the collection firstWhere() method
$collection->firstWhere('post_id', '240231')['meta_value'] ?? null;
With the data you provided this should return 240232. In a dataset where there is no post_id = 240231 it would return null.

unable to delete all nested branches where "product" => null
Have a query
$cartWhere['user_id'] = $user_id;
$cartWhere['site_id'] =$currentSite->id;
$item = Cart::select('product_id','quantity')->with(['product' => function($product) use ($search){
$product->join('product_translations', 'products.id', '=', 'product_translations.product_id');
$product->where( 'product_translations.name', 'LIKE','%'.$search.'%');
},'product.manufacturer:id,name'])
->where($cartWhere)->get();
then I receive collection that has all filtered carts but some of these carts have a relation with product => null
1 => App\Models\Cart {#736 ▼
...
#original: array:2 [▼
"product_id" => 1
"quantity" => 2
]
...
#relations: array:1 [▼
"product" => App\Models\Product {#785 ▶}
]
}
2 => App\Models\Cart {#736 ▼
...
#original: array:2 [▼
"product_id" => 2
"quantity" => 2
]
...
#relations: array:1 [▼
"product" => null
]
}
sorry for my English
You can filter them from the results using the collections filter() method
$item = Cart::select('product_id','quantity')
->with(['product' => function($product) use ($search) {
$product->join('product_translations', 'products.id', '=', 'product_translations.product_id');
$product->where( 'product_translations.name', 'LIKE','%'.$search.'%');
}, 'product.manufacturer:id,name'])
->where($cartWhere)
->get()
->filter(function ($cart) {
return $cart->product !== null;
});
Along with with you should use whereHas. So the result will not include any relation with null value. So this way you can also avoid the extra filter method used.
I have a problem to passing array of arrays from controller to view in Laravel. I've done some research but none of topics helped. My tables are Shops, Items, Items Price. Shops contains shop id, which I get for use from url application/id. In Items Price I got information like shop_id , item_id (these two are FK), price. This table shows which items are in which shops. And in Items I have information about items: id ,picture. When I go to application/1, I want site to show items, which are in this specific shop, information.
My controller method:
public function getItems($id)
{
$items=ItemPrice::where('shop_id', $id)->select('item_id')->get()->toArray();
foreach($items as $item)
$products[] = array(Item::where('id',$item)->get()->toArray());
$shops=Shop::all();
return view('shop')->with(compact(['products','shops']));
}
when I debugging array with dd($products); I get:
array:4 [▼
0 => array:1 [▼
0 => array:1 [▼
0 => array:5 [▼
"id" => 1
"name" => "Item1"
"price" => 0.8
"type" => 2
"img_dir" => "svg/d.jpg"
]
]
]
1 => array:1 [▼
0 => array:1 [▼
0 => array:5 [▼
"id" => 2
"name" => "Item2"
"price" => 1.1
"type" => 2
"img_dir" => "svg/d2.jpg"
]
]
]
2 => array:1 [▼
0 => array:1 [▼
0 => array:5 [▼
"id" => 3
"name" => "Item3"
"price" => 3.1
"type" => 5
"img_dir" => "svg/p1.jpg"
]
]
]
3 => array:1 [▼
0 => array:1 [▼
0 => array:5 [▼
"id" => 4
"name" => "Item4"
"price" => 1.56
"type" => 5
"img_dir" => "svg/p2.jpg"
]
]
]
]
In view I do foreach #foreach($products as $product) and I get error:
Trying to get property 'img_dir' of non-object.
Any help would be appreciated.
Try like this
public function getItems($id)
{
$items = ItemPrice::where('shop_id', $id)
->select('item_id')
->pluck('item_id')
->toArray();
$products = Item::whereIn('id', $items)->get();
$shops = Shop::all();
return view('shop', compact('products','shops'));
}
You have some nested arrays in $products. What you think is a product is in fact an array. Maybe if you simplify your $products variable content :
public function getItems($id) {
$items = ItemPrice::where('shop_id', $id)->select('item_id')->get()->toArray();
$products = [];
foreach($items as $item) {
$products[] = Item::where('id',$item)->get();
}
$shops = Shop::all();
return view('shop')->with(compact(['products', 'shops']));
}
Look at this line
$products[] = array(Item::where('id',$item)->get()->toArray());
$products is an array, and you assign a new element which is an array made by the array value of your query (which contains array).
So you have a 3-level nested array which leads to confusion.
Why don't you just send to your blade view $products = Item::where('id',$item)->get(); ?
I have 2 tables :
Valuechains : id, created_at, updated_at, deleted_at
Segments : id, valuechain_id (Foreign key), created_at, updated_at, deleted_at
And pivot tables (not really important here).
I have a method with sql requests ...
$valuechains list gives me a list of all the value chains which are not (soft) deleted
$valuechainCount counts the number of valuechains which are published
$segmentCount counts the number of segments for each value chains
I try to use the map function in order to add a column which contains the number of segments for each value chains ...
public function vcListAndSegmentCount() {
$valuechainLists = Valuechain::select('valuechains.id', 'lang_valuechain.vcname', 'lang_valuechain.vcshortname')
->join('lang_valuechain', 'valuechains.id', '=', 'lang_valuechain.valuechain_id')
->join('langs', 'lang_valuechain.lang_id', '=', 'langs.id')
->where('langs.isMainlanguage', '=', '1')
->whereNull('valuechains.deleted_at')
->get();
$valuechainCount = Valuechain::whereNull('valuechains.deleted_at')->count();
for ($i=0; $i < $valuechainCount; $i++) {
$segmentCount[$i] = Segment::whereNull('segments.deleted_at')
->where('valuechain_id', '=', $valuechainLists[$i]->id)->count();
}
$valuechainLists = $valuechainLists->map(function ($record) use ($segmentCount) {
$vclists = array_first($segmentCount, function ($value, $key) use ($record) {
return $value['id'] === $record['valuechain_id'];
});
$record['count'] = $vclists;
return $record;
});
dd($valuechainLists);
}
The map methods adds a column my output collection. Unfortunatelly, the new collection is not giving me the right numbers of segments for each value chain... it only adds one value ...
Here is what I obtain :
Collection {#380 ▼
#items: array:4 [▼
0 => Valuechain {#450 ▼
...
#attributes: array:4 [▼
"id" => 1
"vcname" => "Génétique"
"vcshortname" => "Génétique"
"count" => 6
]
#original: array:3 [▶]
...
}
1 => Valuechain {#451 ▼
...
#attributes: array:4 [▼
"id" => 2
"vcname" => "Biotruc"
"vcshortname" => "Biotruc"
"count" => 6
]
...
}
2 => Valuechain {#452 ▼
...
#attributes: array:4 [▼
"id" => 3
"vcname" => "VC3"
"vcshortname" => "VC3"
"count" => 6
]
...
}
3 => Valuechain {#453 ▼
...
#attributes: array:4 [▼
"id" => 4
"vcname" => "VC4"
"vcshortname" => "VC4"
"count" => 6
]
#original: array:3 [▶]
...
}
]
}
I obtain 6, 6, 6 and 6 whereas the count should be 6, 5, 4, 4...
If you are using Laravel >= 5.2 and if you have defined the relationships on the models, you can use the withCount() method.
It would go something like this:
Valuechain::select('valuechains.id', 'lang_valuechain.vcname', 'lang_valuechain.vcshortname')
->withCount(['segments' => function ($query) {
$query->whereNull('deleted_at);
}])
->join('lang_valuechain', 'valuechains.id', '=', 'lang_valuechain.valuechain_id')
->join('langs', 'lang_valuechain.lang_id', '=', 'langs.id')
->where('langs.isMainlanguage', '=', '1')
->whereNull('valuechains.deleted_at')
->get()
or if your Segment model uses the SoftDeletes trait, then it's a bit simpler:
Valuechain::select('valuechains.id', 'lang_valuechain.vcname', 'lang_valuechain.vcshortname')
->withCount('segments')
->join('lang_valuechain', 'valuechains.id', '=', 'lang_valuechain.valuechain_id')
->join('langs', 'lang_valuechain.lang_id', '=', 'langs.id')
->where('langs.isMainlanguage', '=', '1')
->whereNull('valuechains.deleted_at')
->get()
add count value as a property instead of array element.
$valuechainLists = $valuechainLists->map(function ($record) use ($segmentCount) {
$vclists = array_first($segmentCount, function ($value, $key) use ($record) {
return $value['id'] === $record['valuechain_id'];
});
$record->count = $vclists;
return $record;
});
I changed
$record['count'] = $vclists;
to
$record->count = $vclists;
Add a reference: &$segmentCount
$valuechainLists = $valuechainLists->map(function ($record) use (&$segmentCount) {....
Also I'm not sure what your array_first function is doing.
I have the following method of my cart class:
public function add($productId) {
$product = Product::where('id', $productId)->first();
if (!$product) {
return false;
}
if ($this->items->has($productId)) {
$this->items->$productId->qty++;
} else {
$this->items->push([$productId => [
'name' => $product->title,
'price' => $product->price,
'is_sale' => $product->is_sale,
'sale_price' => $product->sale_price,
'sale_percent' => $product->sale_percent,
'can_use_promocode' => $product->can_use_promocode,
'qty' => 1,
]
]);
}
$this->save();
return true;
}
But on dump($cart) in controller, I got this:
+items: Collection {#176 ▼
#items: array:1 [▼
0 => {#171 ▼
+"2": {#164 ▼
+"name": "101 роза"
+"price": 4999
+"is_sale": 0
+"sale_price": null
+"sale_percent": null
+"can_use_promocode": 1
+"qty": 1
}
}
]
}
But I need to:
+items: Collection {#176 ▼
#items: array:1 [▼
2 => {
+"name": "101 роза"
+"price": 4999
+"is_sale": 0
+"sale_price": null
+"sale_percent": null
+"can_use_promocode": 1
+"qty": 1
}
]
}
In this case, I thought that $this->items->push([$productId => ...] will push the key => value pair to collection, but collection creates its own pair, and my pair goes into collection pair. (idk how to describe it correctly, but I think you understand me :) )
Use the put() method instead:
->put($key, $data)
The put method sets the given key and value in the collection
Here is my code :
Controller :
$userOrder = $doctrineOrderRepository->getOrders(Auth::id());
Doctrine:
public function getUserOrders( $userId ) :array
{
$results = $this->_em->createQueryBuilder()
->select( 'o.restaurantId as rtId, o.oCount, o.oPrice ,
o.oCreated', 'o.oId' )
->from( $this->entityClass, 'o' )
->where( "o.userId = '{$userId}'" )
->andWhere( "o.orderItemCount > '0'" )
->andWhere( "o.orderTotalPrice > '0'" )
->getQuery()->getArrayResult();
return $results;
}
I get this array from my database Using Doctrine :
array:1 [▼
0 => array:5 [▼
"rtId" => 154
"oCount" => 2
"oPrice" => 33900
"oCreated" => DateTime {#677 ▶}
"oId" => 17428
]
]
I'm using this Doctrine method in different situations. In this case , I just use two item of all list : rtId , oCount
So , how to modify $userOrder to convert result array to this bellow array?
array:1 [▼
0 => array:2 [▼
"rtId" => 154
"oCount" => 2
]
]
foreach your $userOrder in controller and unset values like this
$newArr = array();
foreach($userOrder as $ar)
{
unset($ar['oPrice']);
unset($ar['oCreated']);
unset($ar['oId']);
$newArr[] = $ar;
}
dd($newArr);
you will get this result..
array:1 [▼
0 => array:2 [▼
"rtId" => 154
"oCount" => 2
]
]
If you are using Laravel, you can use the forever handy collection class. It has dozens of useful methods. In this case you could do:
$cleanedResults = collect($results)->map(function($item) {
return collect($item)->only(['rtId', 'oCount']);
})->toArray();
