如何解决如何使用angularjs和php在xampp中使用指定的用户名和密码从数据库中获取和显示数据？
我对angular JS并不陌生，我一直试图使用Xampp中创建的具有用户名和密码的数据库在网页上显示数据，但我没有这样做。但是，当我使用相同的数据库代码而不显示密码显示数据时，会得到预期的结果。
我显示产品的主页代码：
<?php
session_start();
?>

var app = angular.module('shoppingCart',[]);
app.controller('shoppingCartController',function($scope,$http){
$scope.loadProduct = function(){
$http.get('fetch.php').success(function(data){
$scope.products = data;
})
};
$scope.carts = [];
$scope.fetchCart = function(){
$http.get('fetch_cart.php').success(function(data){
$scope.carts = data;

};
$scope.setTotals = function(){
var total = 0;
for(var count = 0; count<$scope.carts.length; count++)
{
var item = $scope.carts[count];
total = total + (item.product_quantity * item.product_price);
}
return total;
};
$scope.addtoCart = function(product){
$http({
method:"POST",url:"add_item.php",data:product

$scope.removeItem = function(id){
$http({
method:"POST",url:"remove_item.php",data:id
}).success(function(data){
$scope.fetchCart();
});
};
});
</script>
这是fetch.php的代码
<?php
//fetch.php
$connect = new PDO("mysql:host=localhost;dbname=products","dpro","12345");
if($connect){
echo "connected";
}
else{
echo "ERROR: Please check connection in fetch.php";
}
$query = "SELECT * FROM tbl_product";
$statement = $connect->prepare($query);
$statement->execute();
while($row = $statement->fetch(PDO::FETCH_ASSOC))
{
$data[] = $row;
}
echo json_encode($data);
?>
It is clear from this image that data has been fetched from the database
这是add_item.php的代码
<?php
//add_item.php
session_start();
$product_data = json_decode(file_get_contents("php://input"));
$product_id = $product_data->id;
$product_name = $product_data->name;
$product_price = $product_data->price;
if(isset($_SESSION["shopping_cart"]))
{
$is_available = 0;
foreach($_SESSION["shopping_cart"] as $keys => $values)
{
if($_SESSION["shopping_cart"][$keys]['product_id'] == $product_id)
{
$is_available++;
$_SESSION["shopping_cart"][$keys]['product_quantity'] = $_SESSION["shopping_cart"][$keys]['product_quantity'] + 1;
}
}
if($is_available == 0)
{
$item_array = array(
'product_id' => $product_id,'product_name' => $product_name,'product_price' => $product_price,'product_quantity' => 1
);
$_SESSION["shopping_cart"][] = $item_array;
}
}
else
{
$item_array = array(
'product_id' => $product_id,'product_quantity' => 1
);
$_SESSION["shopping_cart"][] = $item_array;
}
//print_r($_SESSION["shopping_cart"]);
?>
在这里，当我有密码和用户名时，如何使用angularjs从数据库中显示产品。
