我需要使用angularjs+php更新mysql数据库中的数据。 Dashboard.html 我的第一页只给出了两个字段：name和position，我使用 ng-repeat 获取代码后，用户将单击编辑按钮，它将重定向到 edit.html 具有相同字段的页面：名称和位置。帮我把那个名字和位置的数据取出来 edit.html 页码

Jmeter 板.html

<div ng-app="myapp" ng-controller="usercontroller">
  <table>
    <th>Name</th>
    <th>Position</th>
    <tbody>
      <tr ng-repeat="x in names">
        <td>{{x.name}}</td>
        <td>{{x.position}}</td>
        <td>
          <a href="edit.html"><span class="glyphicon glyphicon-edit" ng-click="updateData(x.name, x.position)" ></span></a>
        </td </tr>
    </tbody>
  </table>
</div>
<script type="text/javascript">
  var app = angular.module("myapp", []);
  app.controller("usercontroller", function($scope, $http) {
    $scope.updateData = function(name, position) {
      $scope.name = name;
      $scope.position = position;
      $scope.btnName = "Update";
    }
  });
</script>

这是我的 edit.html 页面和我使用的 ng-model 从中绑定数据 dashboard.html ，但不具有约束力。我单击update按钮，数据必须用id更新，我还提到了我的php文件。
我的db名称示例和名为demo的表。

编辑.html

<div ng-app="myapp" ng-controller="EditController">
  <form name="form">
    <div class="form-group">
      <label for="name">Name</label>
      <input class="form-control" type="text" name="name" ng-model="name" /> {{name}}
    </div>
    <div class="form-group">
      <label for="position">Position</label>
      <input class="form-control" type="text" name="position" ng-model="position" />
    </div>
    <input type="submit" name="btnUpdate" class="btn btn-success" ng-click="update_data()" value="{{btnName}}">
  </form>
  <script>
    var app = angular.module("myapp", []);
    app.controller("EditController", function($scope, $http) {
      $scope.btnName = "Update";
      $scope.update_data = function() {
        $http.post(
          "edit.php", {
            'name': $scope.name,
            'position': $scope.position,
            'btnName': $scope.btnName
          }
        ).success(function(data) {
          alert(data);
          $scope.name = null;
          $scope.position = null;
          $scope.btnName = "Update";
        });
      }
    });
  </script>

编辑.php

<?php
    $connect = mysqli_connect("localhost", "root", "", "sample");
    $data    = json_decode(file_get_contents("php://input"));
        if (count($data) > 0) {
        $name     = mysqli_real_escape_string($connect, $data->name);
        $position = mysqli_real_escape_string($connect, $data->position);
        $btn_name = $data->btnName;
            if ($btn_name == 'Update') {
            $id    = $data->id;
            $query = "UPDATE demo SET name = '$name',position = '$position' WHERE id = '$id'";
                if (mysqli_query($connect, $query)) {
                echo 'Updated Successfully...';
                } else {
                echo 'Failed';
                }
            }
        }
    ?>
