Laravel 在字段验证后插入记录
我正在尝试 Laravel 5.6 请求验证。我面临几个问题
1.无法查看视图中的验证消息。
2.添加验证码数据后不插入数据库。（添加验证之前它的工作）
3 如何验证下拉状态？（应选择 Active/Inactive）
designation.blade.php
<form action="{{url('./designation/store')}}" method="POST">
<div class="form-row">
<div class="form-group col-md-7">
<label for="inputDesignation">Designation</label>
<input type="text" name="designation" class="form-control" id="inputDesignation">
</div>
<div class="form-group col-md-5">
<label for="inputStatus_Designation">Status</label>
<select name="status" id="inputStatus_Designation" class="form-control">
<option selected>Select Status</option>
<option >Active</option>
<option >Inactive</option>
</select>
</div>
</div>
<button type="submit" class="btn btn-success" id="btn_add_designation">Add</button>
{{ csrf_field() }}
</form>
指定控制器.php
public function store(Request $request)
{
//Validation the Data
$validatedData = $request->validate([
'designation_type' => ['required','max:255'],
'status' => ['required'],
],
[
'designation_type.required' => 'Designation is required',
'designation_type.max' => 'Designation should not be greater than 255 characters.',
]);
//Data Insert into database
$data =[
'designation_type'=>$request->input('designation'),
'status'=>$request->input('status')
];
DB::table('designation')->insert($data);
return redirect('/designation');
}
请帮我解决这个问题！

尝试以下代码public function store(Request $request){ //Validation the Data $validatedData = $request->validate([ 'designation_type' => ['required','max:255'], 'status' => ['required'], ], [ 'designation_type.required' => 'Designation is required', 'designation_type.max' => 'Designation should not be greater than 255 characters.', ]); if($validatedData->fails()) { return Redirect::back()->withErrors($validatedData); } //Data Insert into database $data =[ 'designation_type'=>$request->input('designation'), 'status'=>$request->input('status') ]; DB::table('designation')->insert($data); return redirect('/designation');}<form action="{{url('./designation/store')}}" method="POST"> <div class="form-row"> <div class="form-group col-md-7"> <label for="inputDesignation">Designation</label> <input type="text" name="designation" class="form-control" id="inputDesignation"> @if($errors->has('designation')) <div class="error">{{ $errors->first('designation') }}</div> @endif </div> <div class="form-group col-md-5"> <label for="inputStatus_Designation">Status</label> <select name="status" id="inputStatus_Designation" class="form-control"> <option selected>Select Status</option> <option >Active</option> <option >Inactive</option> </select> @if($errors->has('status')) <div class="error">{{ $errors->first('status') }}</div> @endif </div> </div> <button type="submit" class="btn btn-success" id="btn_add_designation">Add</button> {{ csrf_field() }} </form> -

public function store(Request $request) { $this->validate($request,[ 'name' => 'required' ]); $category = new Category(); $category->name = $request->name; $category->slug = str_slug($request->name); $category->save(); Toastr::success('Category Successfully Saved','Success'); return redirect()->route('admin.category.index'); }// blade <form method="POST" action="{{ route('admin.category.store') }}"> @csrf <div class="form-group form-float"> <div class="form-line"> <input value="{{ old('name') }}" name="name" type="text" id="category_name" class="form-control"> <label class="form-label">{{ __('Name') }}</label> </div> </div> <br> <a href="{{ route('admin.category.index') }}" class="btn btn-danger m-t-15 waves-effect">{{ __('BACK') }}</a> <button type="submit" class="btn btn-primary m-t-15 waves-effect">{{ __('SUBMIT') }}</button></form> -

参考此https://laravel.com/docs/5.6/validation#named-error-bags后，我对代码进行了一些更改，这有助于解决错误。在designation.blade.php添加 @if ($errors->any())<div class="alert alert-danger"> <ul> @foreach ($errors->all() as $error) <h6>{{ $error }}</h6> @endforeach </ul></div>@endif在DesignationController.php用于状态下拉验证。'status' => 'required|not_in:0',用于数据插入数据库部分DB::table('designation')->insert($validatedData);完整代码designation.blade.php<div class="row"> <div class="col-md-2"></div> <div class="col-md-8"> @if ($errors->any()) <div class="alert alert-danger"> <ul> @foreach ($errors->all() as $error) <h6>{{ $error }}</h6> @endforeach </ul></div>@endif</div> <div class="col-md-2"></div> </div> <div class="row"><div class="col-md-4"></div><div class="col-md-4"> <form action="{{url('./designation/store')}}" method="POST"> <div class="form-row"> <div class="form-group col-md-7"> <label for="inputDesignation">Designation</label> <input type="text" name="designation_type" class="form-control" id="inputDesignation"> </div> <div class="form-group col-md-5"> <label for="inputStatus_Designation">Status</label> <select name="status" id="inputStatus_Designation" class="form-control"> <option selected value="">Select Status</option> <option value="Active">Active</option> <option value="Inactive">Inactive</option> </select> </div> </div> {{-- <button type="submit" class="btn btn-primary">Sign in</button> --}} <button type="submit" class="btn btn-success" id="btn_add_designation">Add</button> {{ csrf_field() }} </form></div> <div class="col-md-4"></div></div>指定控制器.phppublic function store(Request $request){ $validatedData = $request->validate([ 'designation_type' => 'required|max:255', 'status' => 'required|not_in:0', ], [ 'designation_type.required' => 'Designation is required !!', 'designation_type.max' => 'Designation should not be greater than 255 characters.', 'status.required' => 'Status is required !!' ]); DB::table('designation')->insert($validatedData); return redirect('/designation');}谢谢你们花费宝贵的时间来帮助我....!!!
