$ index没有定义错误，当我尝试删除

Question

我正在用angular和php构建一个项目。当我尝试删除时，我有这个错误。该函数获取所有的信息，我不明白为什么它不起作用。任何人都可以请帮忙？

$scope.delete = function(id) 
     { 

        var deleteFile = $scope.files[id]; 
        var txt; 
        var r=confirm("למחוק?"); 
        if(r==true){ 
        // var params = $.param({"id":deletingId}); 
        $http.post('api/customers-tab/delete-priceOffer.php',{id:deleteFile}) 
         .success(function(data){ 

         var arr=JSON.parse(JSON.stringify(data)); 
         $scope.files = arr; 
         var arr2 = arr.split(","); 
          arr2.splice($index, 1); 
          $route.reload(); 



        }); 

       } 

     }; 

HTML：

<tr ng-repeat="x in files track by $index " > 
     <td>{{ x.created}}</td> 
     <td> {{ x.customer_id}} </td> 
     <td> {{ x.full_name}} </td> 
     <td> {{ x.city}} </td> 
     <td> {{ x.phone}} </td> 
     <td><a ng-click="delete($index)" value="Remove" class="btn btn-primary btn- active">מחיקה</a></td> 

PHP：

<?php 



header('Content-Type: text/html; charset=utf-8'); 
$connect=mysqli_connect("localhost", "root", "", "hamatkin"); 

    include_once 'file.php'; 
mysqli_query($connect,"SET character_set_client = utf8"); 
mysqli_query($connect,"SET character_set_connection = utf8"); 
mysqli_query($connect,"SET character_set_results = utf8"); 
// Check connection 
if (mysqli_connect_errno()) { 
    echo "Failed to connect to MySQL: " . mysqli_connect_error(); 
} 
//$customer = new Customer(); 
$data = json_decode(file_get_contents("php://input")); 

$x=$data->id; 


$id = $data->id; 



$del = "DELETE FROM file WHERE id=".$data->id; 



    mysqli_query($connect, $del); 


// echo "delete Ok".$x; 
$newURL = "/hamatkin/#/allPriceOffers"; 
header('Location: '.$newURL); 
?>

更换$index与id，你传入$index价值，但同时在id

arr2.splice(id, 1);
