Php Laravel：使用雄辩的语言从三个表格中选择

我有三张桌子

服务猫（id-猫名）

服务分类猫（id-分类猫id-分类猫名称）

子目录内容（id-子目录id-标题-内容）

我做了这件事

serviceCat

public function serviceSubCat()
    {
        return $this->hasMany('ServiceSubCat');
    }

public function ServicesCat()
    {
        return $this->belongsTo('ServiceCat', 'cat_id');
    }

    public function ssContent()
    {
        return $this->hasMany('SubCatContent');
    }

public function ssCat()
    {
        return $this->belongsTo('ServiceSubCat', 'sub_cat_id');
    }

public function serviceSubCat()
{
    return $this->hasMany('ServiceSubCat', 'cat_id');
}

public function ServicesCat()
{
    return $this->belongsTo('ServiceCat', 'cat_id');
}

public function ssContent()
{
  return $this->hasMany('SubCatContent', 'sub_cat_id');
}

public function ssCat()
{
  return $this->belongsTo('ServiceSubCat', 'sub_cat_id');
}

serviceSubCat

public function serviceSubCat()
    {
        return $this->hasMany('ServiceSubCat');
    }

public function ServicesCat()
    {
        return $this->belongsTo('ServiceCat', 'cat_id');
    }

    public function ssContent()
    {
        return $this->hasMany('SubCatContent');
    }

public function ssCat()
    {
        return $this->belongsTo('ServiceSubCat', 'sub_cat_id');
    }

public function serviceSubCat()
{
    return $this->hasMany('ServiceSubCat', 'cat_id');
}

public function ServicesCat()
{
    return $this->belongsTo('ServiceCat', 'cat_id');
}

public function ssContent()
{
  return $this->hasMany('SubCatContent', 'sub_cat_id');
}

public function ssCat()
{
  return $this->belongsTo('ServiceSubCat', 'sub_cat_id');
}

子内容

public function serviceSubCat()
    {
        return $this->hasMany('ServiceSubCat');
    }

public function ServicesCat()
    {
        return $this->belongsTo('ServiceCat', 'cat_id');
    }

    public function ssContent()
    {
        return $this->hasMany('SubCatContent');
    }

public function ssCat()
    {
        return $this->belongsTo('ServiceSubCat', 'sub_cat_id');
    }

public function serviceSubCat()
{
    return $this->hasMany('ServiceSubCat', 'cat_id');
}

public function ServicesCat()
{
    return $this->belongsTo('ServiceCat', 'cat_id');
}

public function ssContent()
{
  return $this->hasMany('SubCatContent', 'sub_cat_id');
}

public function ssCat()
{
  return $this->belongsTo('ServiceSubCat', 'sub_cat_id');
}

我需要从三个表中提取数据以使用它们

这是我的控制器

public function show($id)
    {
        $serCat = ServiceCat::where('id', $id)->first();
        $getId = $serCat->sub_status;
        if ($getId == 1) {
            $subCats = ServiceSubCat::with('ssContent')->where('cat_id', $id)->get();
            //dd($subCats);
            return View::make('portal.services.servicesDetailsList', compact('serCat', 'subCats'));
        } else {
            return View::make('portal.services.servicesDetails');
        }
    }

public function show($id)
{
    $serCat = ServiceCat::where('id', $id)->with('serviceSubCat.ssContent')->first();
    $getId = $serCat->sub_status;
    if ($getId == 1) {
        return View::make('portal.services.servicesDetailsList', compact('serCat'));
    } else {
        return View::make('portal.services.servicesDetails');
    }
}

现在我发现了一个错误

找不到列

我需要获取猫名、子猫名、标题、内容

确保您的关系定义为：

serviceCat

public function serviceSubCat()
    {
        return $this->hasMany('ServiceSubCat');
    }

public function ServicesCat()
    {
        return $this->belongsTo('ServiceCat', 'cat_id');
    }

    public function ssContent()
    {
        return $this->hasMany('SubCatContent');
    }

public function ssCat()
    {
        return $this->belongsTo('ServiceSubCat', 'sub_cat_id');
    }

public function serviceSubCat()
{
    return $this->hasMany('ServiceSubCat', 'cat_id');
}

public function ServicesCat()
{
    return $this->belongsTo('ServiceCat', 'cat_id');
}

public function ssContent()
{
  return $this->hasMany('SubCatContent', 'sub_cat_id');
}

public function ssCat()
{
  return $this->belongsTo('ServiceSubCat', 'sub_cat_id');
}

serviceSubCat

public function serviceSubCat()
    {
        return $this->hasMany('ServiceSubCat');
    }

public function ServicesCat()
    {
        return $this->belongsTo('ServiceCat', 'cat_id');
    }

    public function ssContent()
    {
        return $this->hasMany('SubCatContent');
    }

public function ssCat()
    {
        return $this->belongsTo('ServiceSubCat', 'sub_cat_id');
    }

public function serviceSubCat()
{
    return $this->hasMany('ServiceSubCat', 'cat_id');
}

public function ServicesCat()
{
    return $this->belongsTo('ServiceCat', 'cat_id');
}

public function ssContent()
{
  return $this->hasMany('SubCatContent', 'sub_cat_id');
}

public function ssCat()
{
  return $this->belongsTo('ServiceSubCat', 'sub_cat_id');
}

子内容

public function serviceSubCat()
    {
        return $this->hasMany('ServiceSubCat');
    }

public function ServicesCat()
    {
        return $this->belongsTo('ServiceCat', 'cat_id');
    }

    public function ssContent()
    {
        return $this->hasMany('SubCatContent');
    }

public function ssCat()
    {
        return $this->belongsTo('ServiceSubCat', 'sub_cat_id');
    }

public function serviceSubCat()
{
    return $this->hasMany('ServiceSubCat', 'cat_id');
}

public function ServicesCat()
{
    return $this->belongsTo('ServiceCat', 'cat_id');
}

public function ssContent()
{
  return $this->hasMany('SubCatContent', 'sub_cat_id');
}

public function ssCat()
{
  return $this->belongsTo('ServiceSubCat', 'sub_cat_id');
}

您的控制器

public function show($id)
    {
        $serCat = ServiceCat::where('id', $id)->first();
        $getId = $serCat->sub_status;
        if ($getId == 1) {
            $subCats = ServiceSubCat::with('ssContent')->where('cat_id', $id)->get();
            //dd($subCats);
            return View::make('portal.services.servicesDetailsList', compact('serCat', 'subCats'));
        } else {
            return View::make('portal.services.servicesDetails');
        }
    }

public function show($id)
{
    $serCat = ServiceCat::where('id', $id)->with('serviceSubCat.ssContent')->first();
    $getId = $serCat->sub_status;
    if ($getId == 1) {
        return View::make('portal.services.servicesDetailsList', compact('serCat'));
    } else {
        return View::make('portal.services.servicesDetails');
    }
}

在您看来，您可以执行以下操作：

{{ $serCat->cat_name }}
@foreach ($serCat->serviceSubCat as $ser)
    {{ $ser->sub_cat_name }}
    @foreach ($ser->ssContent as $subCatContent)
        {{ $subCatContent->title }}
        {{ $subCatContent->content }}
    @endforeach
@endforeach

感谢您的重播，但出现以下错误

未定义属性：illumb\Database\elounce\Collection:：$title

请尝试更新的答案。视图的代码中缺少一个

@foreach

。是的，这项工作刚刚完成。find没有考虑在

foreach

下创建

foreach

，非常感谢@AmitThanks的重播，但出现了此错误

未定义属性：Illumb\Database\Eloquent\Collection:$title

尝试更新的答案。视图的代码中缺少一个

。是的，这很有效，只是查找没有考虑在
