AngularJSの$ routeParamsを使用してURLからPHPスクリプトにIDパラメータを渡しますか？

Question

IDパラメータをPHPに渡して、スクリプト内の特定のSQLデータベース行を取得できるようにします。

IDパラメータはURLで使用できます（例：http://localhost/RoutingAngularJS/index.php#/students/1）。最後の数字1はデータベース内の行idで、その行の人の情報を取得できます。

$ routeParamsが

var app = angular.module("Demo", ["ngRoute"]) 
      .config(function($routeProvider){ 
      $routeProvider 
      . 
      .when("/students/:id", { 
       templateUrl:"Templates/studentDetails.html", 
       controller:"studentDetailsController" 
      }) 
     }) 
      .controller("studentDetailsController", function ($scope, $http, $routeParams) { 
       $http({ 
        url:"api/ReadOneStudent.php", 
         params:{id:$routeParams.id}, 
        method: "get" 

       }).then(function(response){ 
        $scope.student = response.records; 
       })    
      }); 

マイReadOneStudent.phpとしてのコントローラで使用されて、私は今????であり、$スチューデント> IDにIDを渡すのが好き

<?php

// include database and object files 
    include_once 'database.php'; 
    include_once 'Students.php'; 

    // instantiate database and product object 
    $database = new Database(); 
    $db = $database->getConnection(); 

    // initialize object 
    $student = new Students($db); 

    // get id of product to be edited 
    //$data = json_decode(file_get_contents("php://input"));  

    // set ID property of product to be edited 
    $student->id = ????; 

    // read the details of product to be edited 
    $student->readOneStudent(); 

    // create array 
    $student_arr[] = array(
     "id" => $student->id, 
     "name" => $student->name, 
     "gender" => $student->gender, 
     "city" => $product->city 
    ); 
    echo '{"records":[' . $student_arr . ']}'; 
    // make it json format 
    //print_r(json_encode($student_arr)); 

?> 

です。

Students.php

<?php 

/*

    class Students{

      $this->gender = $row['gender']; 
      $this->city = $row['city']; 
     }

?> 

Answer 1

ここではいくつか奇妙なことがあります。まず、あなたのPHP

Students.phpは -

if (!$row = $stmt->fetch(PDO::FETCH_ASSOC)) { 
    return false; 
} 

// set values to object properties 
$this->name = $row['name']; 
$this->gender = $row['gender']; 
$this->city = $row['city']; 

$stmt->closeCursor(); 
return true; 

ReadOneStudent.php便利readOneStudent()戻り何かを作る - 便利状況とJSONで応答

if (!isset($_GET['id'])) { 
    http_response_code(400); // bad request 
    exit; 
} 

$student->id = $_GET['id']; 
if (!$student->readOneStudent()) { 
    http_response_code(404); 
    exit; 
} 

// Seeing as this is called "read ONE student", why return an array? 
header('Content-type: application/json'); 
echo json_encode([ 
    'id'  => $student->id, 
    'name' => $student->name, 
    'gender' => $student->gender, 
    'city' => $student->city 
]); // maybe you can even just use json_encode($student) 
exit; 

次に、私は思いますルート設定でresolveプロパティを使用してください。

$routeProvider.when("/students/:id", { 
    templateUrl: "Templates/studentDetails.html", 
    controller:"studentDetailsController", 
    resolve: { 
     student: function($routeParams, $http) { 
      return $http.get('api/ReadOneStudent.php', { 
       params: {id: $routeParams.id} 
      }).then(function(response) { 
       return response.data 
      }); 
     } 
    } 
}) 

、最終的には自分のコントローラ

.controller('studentDetailsController', function($scope, student) { 
    $scope.student = student; 
}) 

Answer 2

GETするのwiへのアクセスを得るために$_GET['id']を使用するようにしてくださいid in PHP
