Iam是PHP的初学者。
我将session_start();放在header.php的顶部。
。
我的文件结构：
<?php include 'inc/header.php'; ?>
#html_code.....
<?php include 'inc/header.php'; ?>
header.php的总代码：-
<?php
session_start();
if (isset($_POST["addcart"])) {
if (isset($_SESSION["shopping_cart"])) {
$iteam_array_id = array_column($_SESSION["shopping_cart"], "id");
if (!in_array($_GET['id'], $iteam_array_id)) {
$count = count($_SESSION["shopping_cart"]);
$iteam_array = array(
'id' => $_GET['id'],
'title' => $_POST["hidden_name"],
'price' => $_POST["hidden_price"],
'img' => $_POST["hidden_img"],
'quantity' => $_POST["quantity"]
);
$_SESSION["shopping_cart"][$count] = $iteam_array;
} else {
echo "<script>alert('Iteam Already Add')</script>";
}
} else {
$iteam_array = array(
'id' => $_GET['id'],
'title' => $_POST["hidden_name"],
'price' => $_POST["hidden_price"],
'img' => $_POST["hidden_img"],
'quantity' => $_POST["quantity"]
);
$_SESSION["shopping_cart"][0] = $iteam_array;
}
}
if (isset($_GET["action"])) {
if ($_GET["action"] == "delete") {
foreach ($_SESSION["shopping_cart"] as $key => $value) {
if ($value['id'] == $_GET['id']) {
unset($_SESSION["shopping_cart"][$key]);
}
}
}
}
?>
<?php include "lib/session.php"; ?>
<?php
//session::init();
?>
<?php include "config/config.php"; ?>
<?php include "lib/Database.php"; ?>
<?php include "helpers/format.php"; ?>
<?php
$db = new Database();
$fm = new format();
?>
