Laravel : Explode array with relation belongsTo to model - php

I want to explode array value and have successfully doing so by using this code :
#foreach(explode('.', $comment->topic_id) as $topic)
{{ $topic }}
#endforeach
This is the output
Topic : 1,2
The problem is, I want to implement relation belongsTo to the topic_id. When I add the relation and run the code, unfortunately only one of the value is shown.
#foreach(explode('.', $comment->getTopic->topic) as $topic)
{{ $topic }}
#endforeach
This is my model
public function getTopic()
{
return $this->belongsTo('App\Topic', 'topic_id', 'id');
}
Output :
Topic : Laravel
What is the right way to call this array? Please help me. Thank you.

You can't use relationship in this case. If you simply looking for solution then you could do something like the following:
<?php $topic_ids = explode('.', $comment->topic_id);
$topics = App\Topic::whereIn(id, $topic_ids)->get();
?>
#foreach($topics as $topic)
{{ $topic }}
#endforeach
BTW you should structure your database more efficiently.

#foreach(explode(',', $item->chapter_id) as $layer)
<?php
$chapters = DB::table('topic_types')->where('id', $layer)->get();
?>
#foreach ($chapters as $ch)
{{$ch->name}} <br>
#endforeach
#endforeach

Laravel(how to bring two columns from two separate tables in one .blade file) without touching the DB?

What is the most effective way for returning data from two tables in on view?
Like an employee check the vehicle for each order.
Route::get('orderVehicle',"adminController#orderVehicle");
public function orderVehicle(Request $reques){
$orders = new Order;
$vehicles = new Vehicle; $orders->id; $vehicles->id; return view('adminVeiw.orderVehicle',compact('orders','vehicles')); }
#foreach($orders as $or) {{ $or->id }} #endforeach {{ $vehicles->id }}
And the error is
"Trying to get property 'id' of non-object (View:
/var/www/html/full-Restaurant-App-Using-Laravel/resources/views/adminVeiw/orderVehicle.blade.php)"
So any suggestions?
do this if you don't wanna change your code in controller
#foreach($orders as $or)
#if(!empty($or->id))
{{ $or->id }}
#endif
#endforeach
#if(!empty($vahicles->id))
{{ $vehicles->id }}
#endif
in this case you won't get error but i don't know how you wanna this works for you,
i hope it helps
public function orderVehicle()
{
$orders = Order::create();
$vehicles = Vehicle::create();
return view('adminVeiw.orderVehicle', compact('orders', 'vehicles'));
}

Not getting question Model's values in Laravel 5.6

I'm using Laravel 5.6 and I have created two Models Question and User Model and these are linked to each other using one to many relation as:
Question Model
public function user() {
return $this->belongsTo('App\User');
}
User Model
public function questions() {
return $this->hasMany('App\Question');
}
And my controller code is:
public function index()
{
$user = User::all();
return view('home', compact('user'));
}
So, i'm trying to get question title and I have written this code in blade:
#foreach($user as $user)
{{ dd($user->questions->questions_title) }}
#endforeach
But getting error undefined index questions_title, but if only write this {{ dd($user->questions) }} it gave me all questions, so how to fix it.
I have also tried {{ dd($user->questions['questions_title']) }} but not fixed.
You'll want to loop over your questions relationship to see your question:
#foreach($user as $u)
#foreach($u->questions as $question)
{{ dd($question->questions_title) }}
#endforeach
#endforeach
Note: I changed $user to $u
In your controller, you are not eager loading your questions relationships. Change your code to the following:
public function index()
{
$user = User::with('questions')->get();
return view('home', compact('user'));
}
Using the with() method will load all specified relationship with the eloquent query. After this, you will need to loop through the questions collection using the ->each() collection method.
#foreach($users as $user)
#foreach($user->question as $question)
{{ $question->question_title }}
#endforeach
#endforeach
No need for two foreach loops we can simply use one like below:
#foreach ($user->questions as $question)
{{ dd($question->questions_title) }}
#endforeach

How To use Database as a variable with blade template in laravel?

i'm new in laravel, i have some problem to make database as variable to be shown on blade template,
example i want to get any data from database :
{{$get = DB::table('perangkat')->get()}}
then:
#foreach ($get as $got)
{{$got->jabatan}}
#endforeach
if the result of the $got->jabatan is kepala, But i want the result is Change To "Kepala Desa", How can i do ??
Please Help Mee ...
Write database related stuff in model or controller in a method and pass that value to view. It will be very neat and clear
public function getData(){
$get = DB::table('perangkat')->get();
return view('myblade', ['data' => $get]);
}
In your view
#foreach ($data as $got)
{{$got->jabatan}} Desa
#endforeach
Also can you update where you get Desa .so i can update answer according to that.
Updated
you keep different roles in array and do some think like this
<?php
$role=['a'=>'operator','b'=>'admin'] ; ?>
#foreach ($data as $got)
<?php $result = isset($role[$got->jabatan]) ? $role[$got->jabatan] : null; ?>
{{$result}}
#endforeach
company.php
function showdata{
$sql= "this syntax sql";
}
//show data
$company = new company();
#foreach ($company->showdata() as $got)
{{$got->jabatan}}
#endforeach

Laravel many to many relationship access value from Controller in blade

I have two database table
1. patient
--id
--name
2. report
--id
--description
and pivot talbe
patient_report
--id
--report_id
--patient_id
My Patient Model
class Patient extends Model
{
public function reports()
{
return $this->belongsToMany('App\Report' , 'patient_reports');
}
}
My Report Model
class Report extends Model
{
public function patients()
{
return $this->belongsToMany('App\Patient' , 'patient_reports');
}
}
My ReportControlller
public function viewList($reportFloor = null)
{
$report = Report::orderBy('created_at' , 'desc')->paginate(50);
return view('admin.report_list' , ['reports' => $report]);
}
Database : patients table have report_id column and reports table have patient_id column
N.B : I want to find the patient name who has a report. And i am using the laravel dynamic properties like that ---
And finally my blade
#foreach ($reports as $report)
{{ $report->patients->name }}
#endforeach
But it provides an error like that
Try this:
#foreach ($reports->patients as $patient)
{{ $patient->name }}
#endforeach
As the error implies, you're attempting to access the name attribute on a collection. To fix you should change:
#foreach ($reports as $report)
{{ $report->patients->name }}
#endforeach
to:
#foreach ($reports as $report)
#foreach ($report->patients as $patient)
{{ $patient->name }}
#endforeach
#endforeach
In your controller, i would first find the patients and afterwards get their reports.
$patients = Patient::with('reports')->get();
And then in the view i would do:
//This will first get all the patients
#foreach ($patients as $patient)
// This will get each of patients relational reports
#foreach ($patient->reports as $report)
{{ $report->name }}
#endforeach
#endforeach

Unique collection in Laravel

I need to find out unique value. So I tried bellow code. It is through undefined variable error.
Controller:
$employee = Employee::all();
Return view ('page', compact('employee'));
Page view:
$uniqueEmpLoc = $employee->unique('location')->values()->list('location')->toArray();
#Foreach($uniqueEmpLoc as $empLoc)
{{ $empLoc }}
//this is select box used for search
#endforeach
//Display Entire data
#foreach($employee as #employee)
//Display all value
#endforeach
But I got an uniqueEmpLoc is undefined error. I'm using LARAVEL 5.1. Please help me to solve this problem.
There are some errors in your code:
I don't think compact(employee) would work. Shouldn't that suppose to be compact('employee') ?
In Blade, there is no need of putting curly braces at all. Remove them.
Try out the following:
$employees = Employee::unique('locations')->values()->list('location')->toArray();
return view('page', compact('employees'));
And then in your view:
#foreach($employees as $employee)
{{ $employee }}
#endforeach
Use this query in controller
$employees = Employee::distinct()->list('location')->toArray();
return view('page', compact('employees'));
In view
#foreach($employees as $employee)
{{ $employee }}
#endforeach
I agree with the other answers here, this code should be in the controller. You shouldn't be doing logic in the views.
In the controller do:
$uniqueEmpLoc = $employee->unique('location')->values()->list('location')->toArray();
$employee = Employee::all();
Return view ('page', compact('employee', 'uniqueEmpLoc'));
The reason your code isn't working is the line that defines $uniqueEmpLoc is interpreted by blade as text, not code.
If you really want to do that in the view, you need to wrap it in #php tags.
#php
$uniqueEmpLoc = $employee->unique('location')->values()->list('location')->toArray();
#endphp
#Foreach($uniqueEmpLoc as $empLoc)
{{ $empLoc }}
//this is select box used for search
#endforeach
