我需要一些帮助从我的pdf_files表中获取我的user_id,但由于某种原因,当我尝试使用$request = all()
时,它会继续给我一个空数组 - >退回给我{}
和dd($downloads)
将此收藏品{#233 ▼ #items: [] }
归还给我。我是否必须使用声明或任何内容?我看到有人使用它,但我真的需要吗?谢谢你的帮助
代码:
控制器:
public function downfunc(Request $request){
// $downloads = new pdfFile;
$downloads=pdfFile::where('user_id', $request->user_id)->get();
//$downloads=DB::table('pdf_files')->get(); --> this code return results
//dd($downloads);
//return $request->all();
return view('download.viewfile',compact('downloads'));
}
download.blade.php
<table class="table table-bordered">
<thead>
<th>Name of File</th>
<th>Action</th>
</thead>
<tbody>
@foreach($downloads as $down)
<tr>
<td>{{$down->file_name}}</td>
<td>
<a href="download/{{$down->file_name}}" download="{{$down->file_name}}">
<button type="button" class="btn btn-primary">
<i class="glyphicon glyphicon-download">
Download
</i>
</button>
</a>
</td>
</tr>
@endforeach
</tbody>
</table>
pdfFile模型:
protected $fillable = array('file_name','file_size','user_id');
public function personal_infos() {
return $this->belongsTo('App\personal_info', 'user_id', 'id');
}

请确保您的$request->user_id
有效
您可以通过手动运行sql进行检查。
