删除不适用于数据库

我正在使用angular和php构建项目。我有一个"文件"我的数据库中的表,我可以发送文件并检索我需要的所有信息。我添加了一个删除按钮,但我不知道它为什么不起作用。我的控制台没有错误。有人可以看看我的代码吗?

php for deleteing:

<?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->reffer_customer_id;

$reffer_customer_id = $data->reffer_customer_id;
$del = "DELETE FROM file WHERE reffer_customer_id = " . $reffer_customer_id;
//echo $del;
mysqli_query($connect, $del);
$newURL = "/hamatkin/#/allPriceOffers";

header('Location: '.$newURL);

?>

控制器:

$scope.delete = function(deletingId, $index) {

    $http.post('api/customers-tab/delete-priceOffer.php', { "reffer_customer_id" : deletingId })
        .success(function(data) {

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

Html删除按钮:

<td><a ng-click="delete(x.reffer_customer_id, $index)" class="btn btn-primary btn-active">מחיקה</td>

首先,您应该修复HTML:

  1. 我不知道你在ng-click属性上添加删除功能是什么意思,可能你想用on-click代替?如果我错了,请纠正我
  2. 您已打开<a>代码,但</a>缺席
  3. <td>中的已更正HTML按钮是:

    <td><a on-click="delete(x.reffer_customer_id, $index); return false;" class="btn btn-primary btn-active">מחיקה</a></td>
    

    在第二步中,我建议检查表file的MySQL方案,并确保提供相同类型的refferal_customer_id。 例如,我想知道这应该是数值,而不是:

    <?php
    
        header('Content-Type: text/html; charset=utf-8');
    
        /*
         * I propose to check all data before you will open connection to MySQL,
         * because if data is not correct - connection will not be used
         * I strongly propose to process errors in your client scripts
         */
        $data = json_decode(file_get_contents("php://input"));
        if (!isset($data) ||
            !isset($data->reffer_customer_id) ||
            !is_numeric($data->reffer_customer_id)
        ) {
            echo 'Incorrect data specified';
            exit;
        }
    
        /*
         * Connecting
         */        
        $connect = mysqli_connect("localhost", "root", "", "hamatkin");
    
        /*
         * I don't know why you using it for delete query if your id is numeric
         */
        mysqli_query($connect, "SET character_set_client = utf8");
        mysqli_query($connect, "SET character_set_connection = utf8");
        mysqli_query($connect, "SET character_set_results = utf8");
    
        /*
         * I don't recommend you to pass mysql connection error in raw format,
         * because it can be used against you
         * And don't forget to halt your script if error occurred
         */
        if (mysqli_connect_errno()) {
            echo "Failed to connect to MySQL";
            exit;
        }
    
        /*
         * Here your delete query
         */
        $delId = mysqli_real_escape_string($connect, $data->reffer_customer_id);
        if (!$delId) {
            echo 'Incorrect id for delete query specified';
            exit;
        }
    
        /*
         * Don't forget to check errors
         */
        if (!mysqli_query($connect, "DELETE FROM file WHERE reffer_customer_id = $delId")) {
            echo "Failed to delete reffer_customer with id: $delId";
            exit;
        }
    
        /*
         * And close the connection
         */
        mysqli_close($connect);
    
        /*
         * As for me: better to put next route into response for redirecting from client
         * but I don't know what you will do with this, so, putting header
         */
        header('Location: /hamatkin/#/allPriceOffers');

我认为你的查询应该是这样的:

$del = "DELETE FROM file WHERE reffer_customer_id=".$reffer_customer_id." ";
