public function create() {
$user_id = auth()->user()->id;
$makers= Maker::all();
return view('maker.create', compact('makers'));
}
What I wanted to do is how to pass the categories name into the view but the form will accept its id. Please help.
$makers is a collection, so you need to use foreach to iterate:
#foreach ($makers as $maker)
{{ $maker->id }}
#endforeach
Update
If you want to pass it to Form::select, use pluck() method:
$makers = Maker::pluck('name', 'id');
It will generate array, which you can use:
{!! Form::select('selectName', $makers, ....) !!}

I am using my user controller to return his liked documents and it is returning in array rather than object so i want to use carbon diffforhumans with my date field how can we use it .Here is my controllers code
public function myfavourites()
{
// echo "This is myfavourites";
$user_id = Auth::user()->id;
// $liked_post = Like::all()->where('user_id', $user_id);
return view('user.myfavourites')->with('likes', Like::where('user_id', $user_id)->orderBy('created_at', 'DESC')->paginate(12));
}
and here is my blade code
<h6 class="text-muted">Published <b>{{ $like->document['created_at']->diffForHumans() }}</b></h6>
here h6 is in foreach loop where i am looping throw the all liked documents by the user.
i have relation with my like model to with my document model
here is my relationship function
public function document()
{
return $this->belongsTo('App\Document');
}
whats the solution of this problem either i have to return likes in object form if yes then how?
You need to use Carbon class to use diffForHumans(),
<h6 class="text-muted">Published <b>{{ \Carbon\Carbon::parse($like->document['created_at'])->diffForHumans() }}</b></h6>
if its an array you'll either need to loop through each item in the array or use a key for single item
#foreach($like->document as $key => $value)
<h6 class="text-muted">Published <b>{{ \Carbon\Carbon::parse($value['created_at'])->diffForHumans() }}</b></h6>
#endforeach
or through single key
<h6 class="text-muted">Published <b>{{ \Carbon\Carbon::parse($like->document[0]['created_at'])->diffForHumans() }}</b></h6>
I have a relationship this like;
public function foods() {
return $this->hasMany('App\models\food\food', 'category_id', 'id');
}
My controller file content;
$datas = food_category::where('slug', $slug)->with('foods')->paginate(12);
But incoming datas in there all datas and this is causing bad performance. I want to paginate apply relationship datas.
If you want to paginate foods, try adding a separate method for that:
Model:
class food_category
{
public function getFoodsPaginatedAttribute()
{
return $this->foods()->paginate(12);
}
}
Controller:
$datas = food_category::where('slug', $slug)->get();
View:
#foreach ($datas as $data)
#foreach ($data->foods_paginated as $food)
{{ $food->name }}
#endforeach
#endforeach
Pass paginated collection to the view:
//view
#foreach ($datas as $data)
// do what you need
#endforeach
//link
{{$datas->links()}}
I want to count each location in my Job table by using location_id in my job table with id in location table. below code, I can count result correctly but I don't know how to pass this variable to the view. Please help?
//my code
public function index(){
$location = Location::all();
$count_location = [];
foreach ($location as $locations){
$count_location = Job::where('location_id', $locations->id)->count();
}
}
Use withCount() and view() to pass location with counted jobs to the view:
public function index(){
return view('view.name', [
'locations' => Location::withCount('jobs')->get()
]);
}
In the view:
#foreach ($locations as $location)
{{ $location->name }} has {{ $location->jobs_count }} jobs
#endforeach
You can return the collection of locations to the view and then loop through each object in the collection like so:
return view('index', [
'locations'=> $locations,
]);
Then in your index.blade.php you can use something like a #foreach or #forelse loop
#foreach ($locations as $location)
{{ $location->id }}
#endfoeach
EDIT
From the looks of it you would be better off defining a relationship between locations and jobs (i.e. a "many to many" or "one to many" relationship). this would allow you to get the counts for jobs at given locations very easily like so:
$location->jobs->count()
Eloquent relationships are explained in the documentation here
https://laravel.com/docs/5.5/eloquent-relationships
It would be more efficient if construct your query to fetch the count of related models instead of looping through all the results.
Have a look at Counting Related Models in the documentations.
For example, to get the count of all jobs related to a location, you could do:
$locations = App\Location::withCount('jobs')->get();
foreach ($locations as $location) {
echo $location->jobs_count;
}
You need to adjust the code according to your models structure.
Do this
public function index(){
$locations = Location::all();
return view('index', compact('locations'));
}
In your Location model make a relationship by adding this
public function jobs(){
return $this->hasMany(Job::class);
}
In your index view do this
#foreach ($locations as $location)
{{$location->jobs->count}}
#endforeach
Please note that Job should be there in your your model
I'm trying to access a relations table from a collection of data passed in from the controller. I am able to iterate the collection in my view but I am unable to access the relationship data.
There are 2 tables:
stocks (default model)
stock_datas (has a foreign key stock_id which is already setup)
Controller:
public function getstock() {
return view('vehicles.getstock', ['stock' => \App\Stock::all()]);
}
Model (App\Stock) and then (App\StockData)
// From stock model:
public function stockdata() {
return $this->hasOne('App\StockData');
}
// Stock Data model:
public function stock() {
return $this->belongsTo('App\Stock');
}
View (loop):
#foreach ($stock as $k => $v)
{{ print_r($v->stockdata()->get())->year }}
#endforeach
When I try the query below, I get a
Undefined property: Illuminate\Database\Eloquent\Collection::$year (View: F:\websites\tempsite\resources\views\vehicles\getstock.blade.php)
However, year is a column in the stock_datas table.
I am also able to print_r data from the \App\StockData() table so the reference to the table is correct as doing print_r(\App\StockData::all()) from the controller does return all the rows as expected.
What am I doing wrong?
Since it's one to one relation, you should do it like this:
#foreach ($stock as $v)
{{ $v->stockdata->year }}
#endforeach
First one You have to change {{ print_r($v->stockdata()->get())->year }} this line, remove print_r. Next one in foreach loop you can do something like this
#foreach($stock as $one)
{{ $one->stockadata()->first()->year }}
#endforeach
For better solution you should check if isset $one->stockadata()->first()
and after that call ->year. Finally code should be like this
#foreach($stock as $one)
{{ isset($one->stockadata()->first()) : $one->stockadata()->first()->year : 'Default' }}
#endforeach
When calling get() method on any relationship You will always receive collection, no matter what relationship You have.
There are at least two (2) ways to solve Your problem:
1. $v->stockdata->year
2. $v->stockdata()->first()->year
I would suggest You to use first one, because Your stockdata has 1:1 relationship.
Good luck!
For example:
Stock.php model
class Stock extends Model
{
protected $primaryKey = 'id';
function stockdata() {
return $this->hasOne('App\StockDatas', 'id', 'stock_id');
}
public function getStock(){
return Stock::with('stockdata')->get();
}
}
In contriller
public function getstock(Stock $stock) {
return view('vehicles.getstock', ['stock' => $stock->getStock]);
}
view
#foreach ($stock as $k => $v)
{{ $v->stockdata->year }}
#endforeach
I've found many question realated to my problem but couldn't found an answer yet. It's about my foreach loop in my blade.
I want to print all product-names in my blade but I couln't figure out how to do that.
thats how I'm getting the products:
--- current code:
// controller
$id_array = Input::get('id');
$products= Products::whereIn('id', $id_array)->get();
$product_name = [];
foreach($products as $arr)
{
$product_name= $arr->lists('name');
}
returning $product_name gives me this as a output:
["football","cola","idontknow","freshunicorn","dummy-data"]
In my blade is just a simple:
#foreach($products as $product)
{{ $product}}
#endforeach
Error: htmlentities() expects parameter 1 to be string, array given
Thanks for your help and time.
It seems you are getting an object in an array in an array.
Like this:
array(
array(
object
)
)
It happens because you use the get() function to retrieve you model. The get() function always "wants" to retrieve multiple models. Instead you will have to use the first() function.
Like this:
foreach($id_array as $arr)
{
$want2editarray[] = Product::where('id', $arr)->first();
}
Hope it helps :)
Edit after #Wellno comment
That's probably because Product::where('id', $arr)->first(); returns null because it did not find anything.
I forgot to add a check after the retrieving of the product.
This can be done like this:
foreach($id_array as $arr)
{
// First try to get model from database
$product = Product::where('id', $arr)->first();
// If $product insert into array
if ($product) $want2editarray[] = $product;
}
Why do you use loop with IDs? You can find all products by IDs:
$products = Product::whereIn('id', $id_array)->get();
And then use $products in the blade template
#foreach($products as $product)
{{ $product->name }}
#endforeach
try to use Model/Eloquent to fetch data.
View should only display the data and not fetching directly from DB or do heavy calculations.
