I have 1 relation
Order(id, user_id, total_price)
OrderDetail(order_id, product_id, num_of_product)
Product(id, title, num_of_existed, price)
Ask: How to get order across template:
order:[
id: 1,
user_id:1,
total_price:1.1,
order_detail:[
id:1,
order_id:1,
book_id:1,
num_of_product:10
product:[
id:1,
title: 'abc',
num_of_existed: 100,
price: 0.1
]
]
]
Create relationship in your Order model as ,
public function order_details()
{
return $this->hasOne('App\OrderDetail','order_id','id');
}
In your Orderdetail model,
public function product_details()
{
return $this->belongsTo('App\Product','id','product_id'); // first foreign key then local key
}
In your controller
$orders = Order::all();
return view('view_name',compact('orders'));
In the view
#foreach ($orders as $order)
#if ($order->order_details)
{{$order->order_details->num_of_product}}
#if($order->order_details->product_details)
{{$order->order_details->product_details->title}}
{{$order->order_details->product_details->num_of_existed}}
{{$order->order_details->product_details->price}}
#endif
#endif
#endforeach
you can do it via laravel eloquent relationship, to define relationship you will have 3 models like Order, OrderDetail,Product related to corresponding tables.
On your order model:
public function OrderDetail()
{
return $this->hasOne('App\OrderDetail','order_id');
}
On your OrderDetail model:
public function Order()
{
return $this->belongsTo('App\Order','order_id');
}
public function Product()
{
return $this->belongsTo('App\Product','product_id');
}
Then on your controller
public function foo(){
$orders=Order::all(); //remember to use 'App\Order'
return view('filename',compact('orders'));
}
Now on your blade, you will find all related table data just by chaining orders
#foreach ($orders as $order)
#if ($order->OrderDetail)
#if($order->OrderDetail->Product)
{{$order->OrderDetail->Product->title}}
#endif
#endif
#endforeach

I have 3 tables
user, specialities & results
results contain specialitie_id, user_id
I have create many-to-many relationship
Here's the relationship in user model
public function specialities()
{
return $this->belongsToMany(Speciality::class, 'results', 'user_id', 'specialitie_id')->withPivot('result', 'color');
}
I want to fetch data from the result table based on specialitie_id
If my url is
abc.com/result/5
I have attached table structure as well,
it should show me result related to specialitie_id 5
I tried this but it doesn't work
$result = User::with('specialities')->where('id', 5)->get();
Any help would be appreciated.
Your current query:
$result = User::with('specialities')->where('id', 5)->get();
Is saying, give me all results where the USER_ID = 5 WITH all the specialities related to it.
You are very close but did it backwards:
//Give me all results where the SPECIALITY_ID = 5
//WITH all the users related to it
$result = Speciality::with('users')->where('id', 5)->get();
Please note that the above is an array
Example of a Controller Function:
public function results($id){
$results = Speciality::with('users')->where('id', $id)->get();
return view('user_specialities', compact('results'));
}
Example view user_specialities:
#foreach($results as $result)
<p>Result: {{$result->result}}</p>
<p>Formulary: {{$result->formulary}}</p>
<p>Color: {{$result->color}}</p>
<p>User ID: {{$result->user->id}}</p>
<p>User Name: {{$result->user->name}}</p>
#endforeach
Speciality Model:
public function users()
{
return $this->belongsToMany(User::class, 'results', 'specialitie_id', 'user_id')->withPivot('result', 'color');
}
User Model:
public function specialities()
{
return $this->belongsToMany(Speciality::class, 'results', 'user_id', 'specialitie_id')->withPivot('result', 'color');
}
I have relation like this:
DB relation
I have a code in my model that retrieves me just one parent:
public function AllParents()
{
return $this->belongsToMany($this, 'parent', 'product_id', 'parent_id')
->select('parent', 'name');
}
I get it in my controller like this:
private function product(Product $product)
{
return $product->Product()
->with('AllParents')
->get();
}
Finally I need data like this:
Product1/Product_2/Product_3
I think I need a loop, but how to do it in Eloquent?
Just change relationship. You have mentioned pivot table name wrong one.
public function AllParents()
{
return $this->belongsToMany(Product::class, 'Product_parent', 'product_id', 'parent_id') ->select('parent', 'name');
}
and then you can access
\App\Models\Product::with('AllParents')->get()
In your Product Model. You have define relationship like this.
public function allParents()
{
return $this->belongsToMany(Product::class, 'product_parents', 'product_id', 'parent_id')->select('name');
}
And, In Controller you can get all the parents with eager loading.
Product::with('allParents')->find($productId);
And, In View you can use foreach loop to iterate every parent object.
#foreach ($product->allParents as $parentProduct)
{{ $parentProduct->name }}
#endforeach
I did like this:
I modified my controller
private function product(Product $product)
{
$allParents = [];
$parent = null;
$parent->$product->Product()->with('AllParents')->first()->id;
while ($parent != null) {
array_push($allParents, Product::all->find($parent));
$parent = Product::all()->find($parent) - first();
}
}
I have 3 Models "Category" (tableName = 'categories'), "Brand" ('brands'), "Item" ('items')
Can I pass parent column value (e.g. categories) to use it in the Where clause?
Simple example:
Category::with(['brands' => function ($q) {
$q->with(['items' => function ($query) use ($localWhereHas) {
$query->whereColumn('category_id', 'categories.id');
}]);
}]);
Relations are:
Category Model:
public function brands(): BelongsToMany
{
return $this->belongsToMany(Brand::class, 'category_brands')->withPivot('is_visible', 'addon_price');
}
Brand Model:
public function items(): HasMany
{
return $this->hasMany(Item::class, 'brand_id');
}
Item Model:
public function category(): BelongsTo
{
return $this->belongsTo(Category::class, "category_id");
}
The main idea is that I need the structure to be nested like this Category->Brands->Items
The backup plan is to fetch All needed Categories and Foreach them to get as many as categories I have all Brands->Items, using categoryId ($category->category_id) .... but I don't like it
No, you can't pass it directly because it is not the same context.
If you want to have a display like this :
Category
-brand
-item
Then you should maybe just group your items by brand :
$categories = Category::with('items.brand')->get();
#foreach($categories as $category)
{{ $category->name}}
#foreach($category->items->groupBy('brand_id') as $brand_id => $items)
{{ $items->first()->brand->name }}
#foreach($items as $item)
{{ $item->name }}
#endforeach
#endforeach
#endforeach
I have 3 tables school ,schooldetails & admission, and i want to get all data in index page how can i do that , i am getting data of school and admission table due to relationship but not of school details kindly check it and help
school
id
name
name
mobile
city
schooldetails
id
school_id(foreign key of school id)
contact_person
admission
id
school_id(foreign key of school_deatils id)
admission_classes
start_date
end_date
My function
public function schoolslist($class='', $city='')
{
$schools = Admission::where('admission_classes', 'like', "%{$class}%")->where('status', '1')->orderBy('id','desc')->whereHas('school', function($query) use($city) {
$query->where('city', 'like', $city);
})->paginate(10);
return view('frontend.index',compact('schools'));
}
my Admission model
public function School()
{
return $this->belongsTo('App\School');
}
public function SchoolDetails()
{
return $this->belongsTo('App\SchoolDetails');
}
My view
#foreach($schools as $i => $school)
{{ $school->School->name}} from user table Ravi
{{ $school->SchoolDetails->contact_person}} //from school_Details table No result
{{ $school->start_date }} //from admission table date 11/22/2018
#enforeach
SchoolDetails relation should be with school not addmission so remove SchoolDetails() from Admission Model and add it to School Model
School Model:
public function Admission()
{
return $this->hasMany('App\Admission');
}
public function SchoolDetails()
{
return $this->hasOne('App\SchoolDetails'); \\Edited
}
Admission model:
public function School()
{
return $this->belongsTo('App\School');
}
SchoolDetails model:
public function School()
{
return $this->belongsTo('App\School'); \\Edited
}
Then you can change your View accordingly:
#foreach($schools as $i => $school)
{{ $school->School->name}} from user table Ravi
{{ $school->School->SchoolDetails->contact_person}} // This Line is changed
{{ $school->start_date }}
#enforeach
Trying to get products AND variants for a particular supplier.
I can get the products easy enough, but can't figure out how to best get to the variants with matching product_id and send it to the view.
Variants.product_id matches with Product.ID
This works (getting products for the supplier)
public function suppliers($id) {
$supplier = Supplier::orderby('company_name', 'ASC')->find($id);
$products = Supplier::find($id)->products;
$data = [];
$data['supplier'] = $supplier;
$data['products'] = $products;
return view('admin.purchasing.supplier-details', $data);
}
I've tried this to get the variants also without luck.
Controller:
public function suppliers($id) {
$supplier = Supplier::orderby('company_name', 'ASC')->find($id);
$products = Supplier::find($id)->products;
$variants = array();
foreach ($products as $product) {
$product_id = $product->id;
$variants[] = Variant::find($product_id);
}
$data = [];
$data['supplier'] = $supplier;
$data['products'] = $products;
$data['variants'] = $variants;
return view('admin.purchasing.supplier-details', $data);
}
View:
#foreach($products as $product)
<tr>
<td>{{ $product['title'] }}</td>
#foreach($variants as $variant)
#if($variant->product_id == $product['id'])
<td>${{ $variant->price }}</td>
#else
<td>not set</td>
#endif
#endforeach
</tr>
#endforeach
Any tips much appreciated.
First of all , you should have relation set on your models to make this work
like this For exemple :
Supplier.php
public function products()
{
return $this->hasMany('App\Product');
}
Product.php
public function variants()
{
return $this->hasMany('App\Variant');
}
public function Supplier()
{
return $this->belongsToMany('App\Supplier'); //in case you have only one supplier for each product change this to belongsto
}
Variant.php
public function products()
{
return $this->belongsToMany('App\Product'); //not sure if this should be manytomany or one to many , it deppends on what you did
}
anyway now you can do this
Controller
public function suppliers($id) {
$Data = Supplier::where('id',$id)->orderby('company_name', 'ASC')->with('products.variants')->first(); //you will get the supplier with all products associated to him with variants foreach product
return view('admin.purchasing.supplier-details')->with('Data',$Data); // now you just loop the $supplierwithproducts->products to get results (dd the variable to check output)
}
View
{{ $Data->name }} // supplier name since Supplier model was the starting point
#foreach($Data->products as $product) //loop all products related to that supplier
{{ $product->name }} //shows product name (depends on you database columns
#foreach($product->variants as $variant) // loops all variants in the current product
{{ $variant->name }} // shows variants
#endforeach
#endforeach
If you copy and paste this code it might not work ,but this will give you an idea how you should handle relations in laravel (levrage eloquent relations)
