PHP 检查会话是否有特权

Question

我正在处理 MySQL 查询以在数据库中创建产品，但出现错误：

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'desc, fprice, inkoop, image, author, html) VALUES('1', 'bronze 5 - bronze 4', '1' at line 1

我用 Google 搜索了它，但在我的代码中找不到任何问题：

<?php

if(isset($_POST['submit'])) {
    $shopid1 = $_POST['productid'];
    $prodname1 = $_POST['productname'];
    $desc1 = $_POST['desc'];
    $fprice1 = $_POST['fprice'];
    $price1 = $_POST['price'];
    $inkoop1 = $_POST['inkoop'];
    $image1 = $_POST['image'];
    $qty1 = $_POST['qty'];
    $html1 = $_POST['html'];
    $author1 = $_SESSION['name'];



        mysql_query("INSERT INTO products(shopid, name, qty, price, desc, fprice, inkoop, image, author, html) VALUES('$shopid1', '$prodname1', '$qty1', '$price1', '$desc1', '$fprice1', '$inkoop1', '$image1', '$author1', '$html1')", $conn)
            or die(mysql_error());  
        Header("Location: products.php");

} else {

}


?>

希望有人能诊断我的问题！谢谢！

Answer 1

desc 是保留关键字。试试 -

INSERT INTO products(shopid, name, qty, price, `desc`,.....

或相应地重命名。

Answer 2

desc 是一个关键字，它可以使用反引号使用或在数据库中重命名（如果可能）。尝试如下：

INSERT INTO products
(shopid, name, qty, price, `desc`, fprice, inkoop, image, author, html)
VALUES
('$shopid1', '$prodname1', '$qty1', '$price1', '$desc1', '$fprice1', '$inkoop1', '$image1', '$author1', '$html1')

Answer 3

尝试在查询中转义 keyword (desc)

    <?php

if(isset($_POST['submit'])) {
    $shopid1 = $_POST['productid'];
    $prodname1 = $_POST['productname'];
    $desc1 = $_POST['desc'];
    $fprice1 = $_POST['fprice'];
    $price1 = $_POST['price'];
    $inkoop1 = $_POST['inkoop'];
    $image1 = $_POST['image'];
    $qty1 = $_POST['qty'];
    $html1 = $_POST['html'];
    $author1 = $_SESSION['name'];



        mysql_query("INSERT INTO products(shopid, name, qty, price, `desc`, fprice, inkoop, image, author, html) VALUES('$shopid1', '$prodname1', '$qty1', '$price1', '$desc1', '$fprice1', '$inkoop1', '$image1', '$author1', '$html1')", $conn)
            or die(mysql_error());  
        Header("Location: products.php");

} else {

}


?>

您也可以勾选预留关键词，以免下次再犯错MYSQL Reserved Keyword
