Question

我想在一页上显示许多会话消息。第一页是 file_upload.php

// Success!
echo "File was uploaded without errors.<br />" . $_SESSION['message'];
echo "File name is '{$file_name}'.<br />" . $_SESSION['message'];
echo "File references an uploaded file. <br />" . $_SESSION['message'];
echo "File was uploaded without errors" . $_SESSION['message'];

第二个文件是 new.php ，这里是$sql = "INSERT INTO products ";（cat_id，产品名称，文件名，类型，大小，文件名2，类型2，大小2，位置，可见性，内容）

$result = insert_products($products);
if($result === true) {

    $new_id = mysqli_insert_id($db);
    $_SESSION['message'] = 'The product has been created.';

    redirect_to(url_for('/staff/pages/show.php?id=' . $new_id));

第三个是 show.php ，这是函数。

<?php echo display_session_message(); ?>

function get_and_clear_session_message() {
    if(isset($_SESSION['message']) && $_SESSION['message'] != '') {
        $msg = $_SESSION['message'];
        unset($_SESSION['message']);
        return $msg;
    }
}

function display_session_message() {
    $msg = get_and_clear_session_message();
    if(!is_blank($msg)) {
        return '<div id="message">' . h($msg) . '</div>';
    }
}

目前，仅在show.php中显示“产品已创建”消息。可以在一页上显示许多会话消息吗？我想添加所有错误消息表单功能 file_upload.php 。

是否可以在一页中显示许多会话消息
