执行Exception时出错仅执行

Question

我创建了4种输入类型名称，价格，描述，品牌和一种输入文件类型图像。点击提交按钮我希望所有5个输入进入数据库表＆＃34;产品＆＃34;但是在提交被点击时，它只显示例外输出＆＃34;你的一些字段是空的＆＃34;但所有领域都在填补。我甚至可以提供HTML代码。

<?php
    // Do we have a Form Submission
    if (isset($_POST['submit'])) {

        try {

            // Check that all your fields have values
            if (
                (!isset($_POST['name']) || empty($_POST['name'])) ||
                (!isset($_POST['desc']) || empty($_POST['desc'])) ||
                (!isset($_POST['price']) || empty($_POST['price'])) ||
                (!isset($_POST['brand']) || empty($_POST['brand'])) ||
                (!isset($_POST['image']) || empty($_POST['image']))
            ) {
                throw new Exception('Some of your fields are empty.');;
            }
                $filename = $_FILES['fileToUpload']['name'];
                $filetemp = $_FILES['fileToUpload']['temp_name'];
                $filesize = $_FILES['fileToUpload']['size'];
                $filebasename = basename($_FILES['fileToUpload']['name']);
                $dir="uploads/";
                $finaldir=$dir.$filebasename;
                move_uploaded_file($filetemp,$finaldir);

            // Prepare your Query and bind the parameters to the POST array
            $stmt = $db->prepare("INSERT INTO product (name, description, price, brand, image)  VALUES (?, ?, ?, ?, ?)");
            $stmt->bind_param("ssss", $_POST['name'], $_POST['desc'], $_POST['price'], $_POST['brand'], $_POST['image']);

            // Execute your query
            $stmt->execute();

            // Success!
            printf("<p class='msg success'>%s</p>", "Your record was created.");

        } catch (Exception $e) {

            // There was a problem
            printf("<p class='msg error'>%s</p>", $e->getMessage());

        }
    }
    ?>
