Question

我进行了查询，并得到了11个db对象数组的集合。基本上是11个帖子。如果这些帖子（标题，模型或说明中）中存在字符串，则需要进行通配符搜索。如何最好地实现呢？我尝试使用多个orWhere，但似乎无法正常工作。

我的功能

public function search(Request $request)
{
    $this->validate($request, [
        'search' => 'required',
        'country' => 'required',
    ]);
    $search=$request->input('search');
    $posts = Country::where('country_name', $request->input('country'))->first()->posts;

    $customers=$posts::where('title','LIKE','%'.$request->search.'%')
    ->orWhere('model','LIKE','%'.$request->search.'%')
    ->orWhere('notes','LIKE','%'.$request->search.'%')
    ->orWhere('description','LIKE','%'.$request->search.'%')
    ->get();

    dd($posts);
}

$ posts-响应

Answer 1

$posts是指

$posts = Country::where('country_name', $request->input('country'))->first()->posts;

其中不包括搜索查询，您应该转储$customers来查看结果。

此外，您的$customers查询与$posts无关，您正在进行两个不同的查询。您当前的$posts将返回所有国家/地区的帖子。

尝试Query Relations：

$posts = Country::where('country_name', $request->input('country'))->first()->posts()
    ->where('title','LIKE','%'.$search.'%')
    ->orWhere('model','LIKE','%'.$search.'%')
    ->orWhere('notes','LIKE','%'.$search.'%')
    ->orWhere('description','LIKE','%'.$search.'%')
    ->get();

Answer 2

尝试以下查询。

$posts = Country::with(['posts' => function($oQuery) use($search){ 
 $oQuery->where('title','LIKE','%'.$search.'%')
        ->orWhere('model','LIKE','%'.$search.'%')
        ->orWhere('notes','LIKE','%'.$search.'%')
        ->orWhere('description','LIKE','%'.$search.'%');}])->where('country_name', $request->input('country'))->first();
