我写了一段代码,但我猜它不起作用。
给定的代码写在控制器中:
public function store( Request $request )
{
$this -> validate( $request,
[ 'name' => 'required' ,
'status' => 'required',
'created_at' => 'required',
'created_by' => 'required',
'modified_at' => 'required',
'updated_by' => 'required' ] );
if ( request( 'status' ) === 'on' )
{
$status = 1;
# code...
}
else
{
$status = 0;
}
CategoryDetail::Create( [ 'name' => request( 'name' ),
'status' => $status,
'created_at' => request( 'created_at' ),
'created_by' => request( 'created_by' ),
'updated_at' => request( 'modified_at' ),
'updated_by' => request( 'modified_by' ) ] );
\Session::flash( 'create',
'inserted successfully' );
return redirect( 'category/list' );
}
没有异常错误。我只是想知道当字段留空或空时如何显示消息。
这是我的create.blade.php
@extends( 'adminlte::page' )
@section( 'content' )
<!DOCTYPE html>
<html>
<head>
<title>Create</title>
</head>
<body>
<div class = "box box-info">
<form class = "box-body form-group"
method = "POST" action="/category/store">
Name:<input type = "text"
class = "form-control"
name = "name"><br>
Status:<input type = "checkbox"
name = "status"><br>
Created at:<input type = "date"
name = "created_at"><br>
Created by:<input type = "number"
class = "form-control"
name = "created_by"><br>
Modified at:<input type = "date"
name = "modified_at"><br>
Modified by:<input type = "number"
class = "form-control"
name = "modified_by"><br>
<input type = "submit"
value = "create"
name = "Create"><br>
{{csrf_field()}}
{{method_field('PUT')}}
</form>
</div>
</body>
</html>

答案 0 :(得分:1)
你可以通过以下方式获得错误按摩:
@if (count($errors) > 0)
<div class="alert alert-danger alert-dismissable mb30 rtl yekan">
<button aria-hidden="true" data-dismiss="alert" class="close" type="button">×</button>
<ul class="list">
@foreach($errors->all() as $err)
<li class="liste-item">{{ $err }}</li>
@endforeach
</ul>
</div>
@endif
