select desired column from pivot table and show in view - php

Question

These are my model i want to show some desired column in my view as you can see but the issue is that the desired column like employ name employ no is getting from employ table but course name is not showing or displaying in view table. Is there a way to show the course name in course column in view.
This is my View
<table border="1">
<tr>
<th>Full name</th>
<th>Emp no</th>
<th>salary</th>
<th>course</th>
</tr>
#foreach($data as $item)
<tr>
<th>{{$item['Full_name']}} </th>
<th>{{$item['emp_no']}}</th>
<th>{{$item['salary']}}</th>
<th>
#foreach ($data->courses as $course)
{{$course->course_name}}
#endforeach
<th>
</tr>
#endforeach
</table>
This is my employ model class:
class employ extends Model
{
use HasFactory;
public $timestamps = false;
protected $guarded = [];
public function courses() {
return $this->belongsToMany(course::class, 'employ_course');
}
}
This is my course model class:
class course extends Model
{
use HasFactory;
public $timestamps = false;
protected $guarded = [];
public function employs() {
return $this->belongsToMany(employ::class, 'employ_course');
}
}
And this is my employ_course(pivot table) model class:
class employcourse extends Model
{
use HasFactory;
protected $guarded = [];
}
This is my controller:
public function show()
{
$datas = employ::with([('course')
=> function ($query) {
$query=course::select('course_name');
}])
->select('Full_name', 'salary', 'emp_no')
->get();
return view('teacher.teacher_data', ['datas' => $datas]);
}

Answer 1

in your nested #foreach in view $data should be $item to iterate over all courses from employee.
Then in your controller the $data could be like this:
$datas = employ::with('course')
->select('employ.Full_name', 'employ.salary', 'employ.emp_no', 'course.course_name')
->get();
Remember that class names must start with uppercase letters and database rows with lowercase.

Answer 2

You can achieve that goal with this:
public function show()
{
// you need the employ "id" column to retrieve the related courses
$datas = employ::with('courses:course_name')->get(['id', 'Full_name', 'salary', 'emp_no']);
return view('teacher.teacher_data', ['datas' => $datas]);
}
And your view, I think should be as following:
<table border="1">
<tr>
<th>Full name</th>
<th>Emp no</th>
<th>salary</th>
<th>courses</th>
</tr>
#foreach($data as $item)
<tr>
<td>{{$item['Full_name']}}</td>
<td>{{$item['emp_no']}}</td>
<td>{{$item['salary']}}</td>
<td>
#foreach ($data->courses as $course)
{{$course->course_name}}
#endforeach
</td>
</tr>
#endforeach
