Laravel独特的验证从标签输入多个值 [英] Laravel unique validation for multiple values from tags input

问题描述

我需要使用标签上输入laravel独特的验证，但我面对的问题有多个值，独特的规则运作良好时插入一个值，但如果添加多个值，但这并没有工作。

I need to use laravel unique validation over tags inputs,but i face issue with multiple values ,the unique rule working well when insert one value, but when add more than one value it does't work .

这是我的控制器code

this my controller code

 public function createteacher()
 {
     $rules = array (
         'teacher-name'  => 'required|unique:teacher,name',
     );

     $msgs =array(
         'teacher-name.required' => 'please insert teacher name',  
         'unique' => 'teacher name already exist',
     );

     $validator = Validator::make(Input::all(),$rules,$msgs);

     if ($validator->fails())
     {
         return  Response::json(['success'=>false,'error'=>$validator->errors()->toArray() ]);
     }
     else
     {
         $c = count(explode(',', Input::get('teacher-name')));

         $teachers_ids = explode(',', Input::get('teacher-name'));

         //if Validated
         for ($i = 0 ; $i < $c ; $i++)
         {
             $new_teacher = Teacher::firstOrCreate(array('name'=>$teachers_ids[$i]));  
         }

         return Response::json(['success'=>true]); 
     }
 }

和本我的看法code

and this my view code

<div class="col-md-6">
 <div class="box box-redorange">
  <div class="box-header">
   <h3 class="box-title" style="float:right"> Adding Teachers </h3>
  <i class="fa fa-spinner fa-spin fa-lg" style="display:none float:left;" id="teacher-adding-load"></i> &nbsp;
   </div>
  <div class="box-body">                                    

     {{Form::open(array('url'=>'management/createteacher','id'=>'teacher-form'))}}
   <div class="form-group">
    <label for="teacher-name[]">Teacher Name </label>
    <select multiple data-role="tagsinput" name="teacher-name[]"   id="teacher-name" class="form-control" autofocus="true">
           <option value="" ></option>
    </select>
      </div>                     
      </div> <!-- end box body-->
      <div class="box-footer">
      {{Form::submit('Add',array('style'=>'color:#fff;font-weight:bold; ','class' => 'btn btn-redorange btn-block btn-sm')) }}
       {{Form::close()}}
       </div> <!--end box footer -->
       </div> <!-- end box -->
       <div class="form-group help-block teahcer-form-msgs" style="display:none;">
             <small></small>
       </div> 
      </div> <!-- end col-m-6 -->

终于我的ajax code

finally my ajax code

 $(document).ready(function(){

 var msgs = $('.teahcer-form-msgs');

 $('#teacher-form').submit(function(e){
  e.preventDefault();
 var $teacher_loading = $('#teacher-adding-load').show();

   // form data
    var formData = new FormData ();

     formData.append('teacher-name' , $('#teacher-name').val());

 $.ajax({
 url:'/elaqsacenter/public/management/createteacher',
 method:'post',
 processData:false,
 contentType:false,
 cache:false,
 dataType: 'json',
 data:formData,
 complete:  function(){
      $teacher_loading.hide();
  },
   global: false,
   success:function(data){

   msgs.hide().find('small').empty();

   if (!data.success) {

    $.each(data.error,function(index,error){

        msgs.find('small').append('<p class="text-danger">'+'<span     

       class="glyphicon glyphicon-exclamation-sign" aria-hidden="true">

       </span>'+' '+error+'</p>');

      // disable submit button when throw Validation messages 
     $('input[type=submit]').prop("disabled", true);
       setTimeout(function() {
       $('input[type=submit]').prop("disabled", false);
      }, 4000);
  });
    msgs.slideDown();
    msgs.delay(3000).slideUp();

  }else{
 msgs.find('small').append('<p class="text-success">data Inserted</p>');
      msgs.slideDown();
      msgs.delay(3000).slideUp();
      setTimeout(function(){location.reload();},2000);  
   }

 },
  global: false,
  error:function(){},

   });

  });

});

我的主要问题是如何我可以使用独特的规则与标签输入插入多个值

推荐答案

我找到更简单的方法可以遍历tagsInput值来验证它，如下

I found more simple way can loop over tagsInput values to validate it as below

   $c = count(Input::get('teacher-name') );

    //In view the name must be  name="teacher-name[]"
   $teacher_name =Input::get('teacher-name');

   /* To loop over multiple values that insert from tags input.
      you can add all laravel validation with this way .
      and custom :attribute by setAttributeNames() method */      
    for ($i = 0; $i < $c ; $i++){

   $rules[$i] = 'required|between:3,15';

   $customAttributes[$i] =  $i + 1  ;
}

    $msgs =  array('required' => '.Teacher Name Is Required' ,
                   'between' => '.Teacher Num  (:attribute) must be between 3 : 15 chars' ) ; 

    $validateTeacher = Validator::make($teacher-name,$rules,$msgs);
    $validateTeacher->setAttributeNames($customAttributes); 

      if ($validateDivision->fails() OR $validateGrade->fails()) 
    {
       // return Ajax Validation Messages OR laravel Validation Messages 
    }

通过以上方式，您可以遍历tagsInput值一个接一个，享受:)

By the above way you can loop over tagsInput values one by one, Enjoy :)
