如何从数据库中的 2 个不同 table 中的 Laravel 中的选定选项中获取值
How to get Value from Selected Option in Laravel from 2 different table in database
我想获取它的值以将其插入到我的游戏 table 数据库中。但我必须显示数据库中流派 table 中的流派名称。
查看:
<select name="genreid">
@foreach($genres as $genre)
<option value="{{ $genre->genreid }}"> {{ $genre->genre }}</option>
@endforeach
</select>
控制器:
public function insertgame(Request $request){
$this -> validate($request, array(
'gamename' => 'required|min:3',
'price' => 'required|int|min:1',
'genre' => 'required',
'releaseddate' => 'required|date',
'picture' => 'required|mimes:jpeg,jpg,png,gif'
));
$gamename = $request->input('gamename');
$genreid = $request->input('genreid');
$price = $request->input('price');
$releaseddate = Carbon::parse($request->input('releaseddate'));
$picture = $request->file('picture')->getClientOriginalName();
$data=array('gamename' => $gamename, 'genreid'=>$genreid, 'price'=>$price,'releaseddate'=>$releaseddate,'picture'=>$picture );
DB::table('games')->insert($data);
return redirect('managegame');
}
做这样的事情
@foreach($game->genres as $genre)
{
<option value='{{$genre->id}}' {{$game->genre ==$genre->id ? 'selected' :' '> {{$genre->name}} </option>
}
你说过如果你使用这个它对你有用 HTML:
<select name="genre">
<option selected disabled>Choose one</option>
<option value="FPS">FPS</option>
<option value="Action">Sports</option>
<option value="Action">Action</option>
<option value="Racing">Racing</option>
<option value="Simulation">Simulation</option>
</select>
在这种情况下,要使用正确的数据格式,请更改:
<option value="{{ $genre->genreid }}">{{ $genre->genre }}</option>
收件人:
<option value="{{ $genre->genre }}">{{ $genre->genre }}</option>
我找到答案了!
我刚换了
'genre' => 'required',
至
'genreid' => 'integer|required',
哈哈谢谢大家
