Question

我正在尝试，如果用户单击shop-male.php中的添加到购物车按钮，它将转到add_cart.php，在处理完成后，它将再次重定向shop-male.php，但是如果用户单击shop-single.php，该怎么办？我想在shop-single.php上经过重定向后我们更了解我的代码在这里

shop-male.php

<a href="add_cart?id=<?php echo $row['id']; ?>" class="btn btn-primary btn-sm"><span class="glyphicon glyphicon-plus"></span> Cart</a>

add_cart.php

<?php
session_start();

//check if product is already in the cart
if(!in_array($_GET['id'], $_SESSION['cart'])){
    array_push($_SESSION['cart'], $_GET['id']);
    $_SESSION['message'] = 'Product added to cart';
}
else{
    $_SESSION['message'] = 'Product already in cart';
}

header('location: shop-male');

？>

另一个页面是shop-single.php

<a href="add_cart?id=<?php echo $row['id']; ?>"> <button class="btn btn-primary"><i class="icon-bag"></i> Add to Cart</button> </a>

我想在用户点击“添加到购物车”后在同一页面上执行重定向操作

Answer 1

在标题函数中使用$_SERVER['HTTP_REFERER']。在此处详细了解：http://php.net/manual/en/reserved.variables.server.php

Answer 2

尝试

header('Location: ' . $_SERVER['HTTP_REFERER']);

Answer 3

尝试以下代码在GET值中分配重定向页面

shop-male.php

<a href="add_cart?id=<?php echo $row['id']; ?>&redirect=shop" class="btn btn-primary btn-sm"><span class="glyphicon glyphicon-plus"></span> Cart</a>

add_cart.php

<?php
session_start();

//check if product is already in the cart
if(!in_array($_GET['id'], $_SESSION['cart'])){
    array_push($_SESSION['cart'], $_GET['id']);
    $_SESSION['message'] = 'Product added to cart';
}
else{
    $_SESSION['message'] = 'Product already in cart';
}

if($_GET['redirect']=='single')
{
  header('location:  shop-single');
}
else
{
  header('location: shop-male');

}
?>

shop-single.php

<a href="add_cart?id=<?php echo $row['id']; ?>&redirect=single"> <button class="btn btn-primary"><i class="icon-bag"></i> Add to Cart</button> </a>

Answer 4

您可以检查以下内容：

if (isset($_SERVER["HTTP_REFERER"])) {
        header("Location: " . $_SERVER["HTTP_REFERER"]);
    }

或

您必须重定向具有当前产品ID的男性商店页面。您可以使用以下代码：

$host = $_SERVER['HTTP_HOST'] . '/';
$project = explode('/', $_SERVER['REQUEST_URI'])[1];
header('location: $host.$project.'/shop-male?'.$_GET['id']);

从ID即将到来的页面重定向
