Question

我想在其类别名称下获取帖子。我在网上尝试了很多教程，但这些教程都不适合我！

这是我的控制器：

public function showcoursecat($slug) {
    $coursecateories = course::with('coursecateory')
        ->where('slug', $slug)
        ->get();

    return view ('frontend.coursecats', compact('coursecateories'));
}

这是我的路线：

Route::get('/courses/cat/{slug}', 'FrontendController@showcoursecat')
    ->name('coursecat')
    ->where('slug', '[\w\d\-\_]+');

我的课程模式：

class Course extends Model
{
    use Notifiable;

    protected $table = "Courses";

    protected $fillable = [
        'course_name', 
        'course_description', 
        'course_price', 
        'course_disscount',  
        'slug', 
        'image', 
        'category_id', 
        'user_id', 
        'approve',
    ];

    protected $events = [
        'created' => Events\CourseApproved::class,
    ];

    public function user() {
        return $this->belongsTo(User::class);
    }

    public function coursecateories() {
        return $this->belongsTo(Coursecateory::class, 'category_id');
    }
}

我的课程模式：

class Coursecateory extends Model
{
    protected $fillable = [
        'name', 
        'image', 
        'slug',
    ];

    public function courses() {
        return $this->hasMany(Course::class, 'category_id');
    }
}

以下是我的观点：

@foreach($coursecateories as $coursecateory)

    <h3>{{ $coursecateory->course_name }}</h3>

    @foreach($coursecateory->courses as $course)

        <h4><a href="#">{{ $course->course_name }}</a></h4>

        <p>{{ $course->course_description }}</p>

    @endforeach

@endforeach

你应该这样做：

$coursecateories = Coursecateory::with('courses')->where('slug', $slug)->get();

在视图中，我认为您的意思是<h3>{{ $coursecateory->name }}</h3>而不是<h3>{{ $coursecateory->course_name }}</h3>：

@foreach($coursecateories as $coursecateory)

    <h3>{{ $coursecateory->name }}</h3>

    @foreach($coursecateory->courses as $course)

        <h4><a href="#">{{ $course->course_name }}</a></h4>
        <p>{{ $course->course_description }}</p>

    @endforeach

@endforeach

根据评论的分页需要，您可以这样做：

$category = Coursecateory::where('slug', $slug)->first();
$courses = $category->courses()->paginate(10);
return view('frontend.coursecats', compact('category', 'courses'));

在视图中：

<h3>{{ $category->name }}</h3>
@foreach($courses as $course)

    <h4><a href="#">{{ $course->course_name }}</a></h4>
    <p>{{ $course->course_description }}</p>

@endforeach
