最后得出的结果就是fail
orderNo是订单号应该自增的,但是我不会,所以就只是随便赋了一个值
session_start();
$corn=mysql_connect('localhost','root','');
mysql_query('set names UTF8',$corn);
if (!$corn) {
die('Could not connect: ' . mysql_error());
}
$db_selected=mysql_select_db( "daydream" ,$corn);
if (!$db_selected) {
die ('Can\'t use foo : ' . mysql_error());
}
$time=date("Ymd");
echo $time;
$id=$_GET['id'];
$presult=mysql_query("select * from production where proNo=$id");
$pinfo=mysql_fetch_array($presult);
$sum=$_POST['proNum']*$pinfo['proPrice'];
$num=12;
$sql="INSERT INTO order(orderNo,cusNo,orderDate,orderSum,orderAddress) VALUES ('$num','$_SESSION[admin]', '$time','$sum','$_POST[orderAddress]')";
if (!mysql_query($sql,$corn))
echo "fail";
else
echo "success";
?>
回复讨论(解决方案)
你把 echo "fail" 改成
echo mysql_error();
就真相大白了!
orderNo 是自增的,也就是主键
而主键是不可重复的
你给他赋予 $num 的值,那就有可能违规了
既然你在插入时开列了字段名,那自增字段就不需要也在其中了
$sql="INSERT INTO order(cusNo,orderDate,orderSum,orderAddress) VALUES ('$_SESSION[admin]', '$time','$sum','$_POST[orderAddress]')";
因为我对auto_increasement不熟悉 我也没把orderNo设为主键 但是 刚刚按照你说的改了一下 报错如下:
Error: 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 'order(cusNo,orderDate,orderSum,orderAddress) VALUES ('1', '20140731','94','2')' at line 1
就还是我的插入语法有问题还是什么........
order 加上转义字符试试。
$sql="INSERT INTO `order`(cusNo,orderDate,orderSum,orderAddress) VALUES ('$_SESSION[admin]', '$time','$sum','$_POST[orderAddress]')";
加了转义字符没有用啊
现在还报什么错?同时贴出show create table order; 看看。
错误还是上面那个:
Error: 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 'order(cusNo,orderDate,orderSum,orderAddress) VALUES ('2', '20140731','94','111'' at line 1
说是有语法错误
我的数据表是这样的(这是一张订单表 用于购买时生成订单记录的)
orderNo 应该设置为自动编号和主键
$sql="INSERT INTO order(cusNo,orderDate,orderSum,orderAddress) VALUES ('$_SESSION[admin]', '$time','$sum','$_POST[orderAddress]')";
echo $sql;
贴出结果看看
现在你的$sql 是如何写的?贴出来看看。是不是复制我#3 的代码。
结果是:
INSERT INTO order(cusNo,orderDate,orderSum,orderAddress) VALUES ('2', '20140731','94','1111')
Error: 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 'order(cusNo,orderDate,orderSum,orderAddress) VALUES ('2', '20140731','94','1111' at line 1
我的代码:就是和#3一样的
$sql="INSERT INTO order(cusNo,orderDate,orderSum,orderAddress) VALUES ('$_SESSION[admin]', '$time','$sum','$_POST[orderAddress]')";
echo $sql;
echo"";
if (!mysql_query($sql,$corn))
die('Error: ' . mysql_error());
else
echo "success";
?>
orderfNo已经设为主键 并且自增了
`order` 注意前后转义符。
改成这样:
$sql="INSERT INTO 'order' (cusNo,orderDate,orderSum,orderAddress) VALUES ('$_SESSION[admin]', '$time','$sum','$_POST[orderAddress]')";
echo $sql;
没差耶 错误提示变成这样了:
INSERT INTO 'order' (cusNo,orderDate,orderSum,orderAddress) VALUES ('2', '20140731','94','1111')
Error: 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 ''order' (cusNo,orderDate,orderSum,orderAddress) VALUES ('2', '20140731','94','1' at line 1
因为我在做一个简单的购物网站 ,
注册都通了 就是说用户表可以添加信息了,
到购买这里死活加不进去 死磕了好几天了 我觉得大致的原理是一样的 可是都没成功
拜托大家帮帮忙,谢谢啦
让你复制我的代码就那么难吗?
`` 是Tab键上方的字符,不是单引号。
成功了
谢谢楼上的大哥!!!!!!!!!!!!好棒啊 我真以为是单引号。。。。。

Arrays can be stored in PHP sessions. 1. Start the session and use session_start(). 2. Create an array and store it in $_SESSION. 3. Retrieve the array through $_SESSION. 4. Optimize session data to improve performance.

PHP session garbage collection is triggered through a probability mechanism to clean up expired session data. 1) Set the trigger probability and session life cycle in the configuration file; 2) You can use cron tasks to optimize high-load applications; 3) You need to balance the garbage collection frequency and performance to avoid data loss.

Tracking user session activities in PHP is implemented through session management. 1) Use session_start() to start the session. 2) Store and access data through the $_SESSION array. 3) Call session_destroy() to end the session. Session tracking is used for user behavior analysis, security monitoring, and performance optimization.

Using databases to store PHP session data can improve performance and scalability. 1) Configure MySQL to store session data: Set up the session processor in php.ini or PHP code. 2) Implement custom session processor: define open, close, read, write and other functions to interact with the database. 3) Optimization and best practices: Use indexing, caching, data compression and distributed storage to improve performance.

In PHP, iterating through session data can be achieved through the following steps: 1. Start the session using session_start(). 2. Iterate through foreach loop through all key-value pairs in the $_SESSION array. 3. When processing complex data structures, use is_array() or is_object() functions and use print_r() to output detailed information. 4. When optimizing traversal, paging can be used to avoid processing large amounts of data at one time. This will help you manage and use PHP session data more efficiently in your actual project.

The session realizes user authentication through the server-side state management mechanism. 1) Session creation and generation of unique IDs, 2) IDs are passed through cookies, 3) Server stores and accesses session data through IDs, 4) User authentication and status management are realized, improving application security and user experience.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),

SecLists
SecLists is the ultimate security tester's companion. It is a collection of various types of lists that are frequently used during security assessments, all in one place. SecLists helps make security testing more efficient and productive by conveniently providing all the lists a security tester might need. List types include usernames, passwords, URLs, fuzzing payloads, sensitive data patterns, web shells, and more. The tester can simply pull this repository onto a new test machine and he will have access to every type of list he needs.
