Question

我想从用户输入将json数组存储到数据库中。但是，我没有得到理想的结果。以下是代码：

HTML /视图

<div class="form-group" id="InputsWrapper" {{$errors->has('qualification') ? 'has-error': ''}}>
    <div class="col-sm-10">
        <input class="form-control" type="text" name="qualification[]" id="field_1" value=""><a href="#" class="removeclass"></a> @if($errors->has('qualification'))
        <span class="help-block">{{$errors->first('first')}}</span> @endif
    </div>
</div>
<div id="AddMoreFileId">
    <a href="#" id="AddMoreFileBox" class="btn btn-info ">Add field</a>
    <br>
    <br>
</div>

控制器

public function store(Request $request)
{
    //
    $request->validate([
        'qualpurpose' => 'required',

    ]);


    $qualpurpose = Qualpurpose::create([
        'qualpurpose' => $request->input('qualpurpose'),

        'qualification' => json_encode($request->input('qualification')),
        'qualificationheader_id'=>session()->get('key')

    ]);


    if ($qualpurpose) {

        return redirect()->route('qualpurposes.show', ['qualpurpose' => $qualpurpose->id])
            ->with('success', 'Purpose created Successfully');
    }


    return back()->withInput()->with('error' , 'Purpose could not be created');
}

我希望输入以下列格式存储：

{"a":1,"b":2,"c":3,"d":4,"e":5}

但相反，我得到

["adfadsf","bgadf qwe asd","adfadsf ase asdf asder","adfadsf qwer","asdf ffase weww","qwess cfesdf"]

'['方括号而不是普通的花括号。有没有办法可以确保数据存储为普通的json数组而不是方括号？

Answer 1

如http://php.net/manual/en/function.json-encode.php中所述，您可以使用qf=word

JSON_FORCE_OBJECT

Answer 2

更改此行：

 Quarter breakid freq
      Q3      01    1
      Q4      01    2
      Q4      15    2

要

    'qualification' => json_encode($request->input('qualification')),
