MySQL Query:SELECT * FROM [pre]vipcenter_25 WHERE status=3 ORDER BY LIMIT 0,20
MySQL 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 'LIMIT 0,20' at line 1 MySQL Errno:0
Message:MySQL Query Error

我想在公司主页上添加一个“成功案例”的新模块，复制的“品牌展示”的模块，把代码中的brand批量替换成success，其他都没问题就是在后台模块编辑时候出现这个报错

回复讨论(解决方案)

SELECT * FROM [pre]vipcenter_25 WHERE status=3 ORDER BY LIMIT 0,20
检查下sql，是否可以执行。

ORDER BY XX LIMIT 0,20

不能执行，，

SELECT * FROM [pre]vipcenter_25 WHERE status=3 ORDER BY LIMIT 0,20
多了套红的部分，如何你能运行？

SELECT * FROM [pre]vipcenter_25 也报错

SQL] SELECT * FROM [pre]vipcenter_25

[Err] 1064 - 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 '[pre]vipcenter_25' at line 1

确定你表的名称书写正确，还有order by xx xx必须为表的字段属性，你上面未加上。

我试了，加上了也不行啊

确定你表的名称书写正确，还有order by xx xx必须为表的字段属性，你上面未加上。
are you sure?

其实我也不太懂，我是个新手，但是我是完全复制的原有的模块的代码，数据库也新建了表，不知道是哪里出了问题

确定你表的名称书写正确，还有order by xx xx必须为表的字段属性，你上面未加上。
1.select * from tablename?
2.select * from tablename order by id?

SELECT * FROM destoon_vipcenter_25 WHERE status=3 ORDER BY edittime LIMIT 0,20 可以查询

输出看看：
die("SELECT * FROM {$this->table} WHERE $condition ORDER BY $order LIMIT $offset,$pagesize");
检查{$this->table}，$condition,$order , $offset, $pagesize,对应是否有值

SELECT * FROM [pre]vipcenter_25 也报错

表名字怎么会出现这个？

输出看看：
die("SELECT * FROM {$this->table} WHERE $condition ORDER BY $order LIMIT $offset,$pagesize");
检查{$this->table}，$condition,$order , $offset, $pagesize,对应是否有值

什么都没输出，没有值

SELECT * FROM [pre]vipcenter_25 也报错

表名字怎么会出现这个？

这个我也不清楚，以前没学过php

源代码：

echo "SELECT * FROM {$this->table} WHERE $condition ORDER BY $order LIMIT $offset,$pagesize";
die();

输出：SELECT * FROM destoon_vipcenter_25 WHERE status=3 ORDER BY LIMIT 0,20

echo "SELECT * FROM {$this->table} WHERE $condition ORDER BY $order LIMIT $offset,$pagesize";
die();

再试试

你还是针对这个问题，贴出输出结果吧，不然你问的问题，没办法解答了。

问题算是解决了，function get_list($condition = 'status=3', $order = 'edittime DESC', $cache = '') {
global $MOD, $pages, $page, $pagesize, $offset, $items, $sum;
if($page > 1 && $sum) {
$items = $sum;
} else {
$r = $this->db->get_one("SELECT COUNT(*) AS num FROM {$this->table} WHERE $condition", $cache);
$items = $r['num'];
}
$pages = defined('CATID') ? listpages(1, CATID, $items, $page, $pagesize, 10, $MOD['linkurl']) : pages($items, $page, $pagesize);
$lists = $catids = $CATS = array();

$result = $this->db->query("SELECT * FROM {$this->table} WHERE $condition ORDER BY $order LIMIT $offset,$pagesize", $cache);

是获得不了$order的值，直接用edittime DESC代替$order,运行没问题。但是现在不明白是为什么获得不了$order的值

echo "SELECT * FROM {$this->table} WHERE $condition ORDER BY $order LIMIT $offset,$pagesize";
die();

再试试

你还是针对这个问题，贴出输出结果吧，不然你问的问题，没办法解答了。

还是非常感谢你！

这个问题我告诉你原因吧，你复制了模块之后没对模块进行设置点击菜单最下面模块设置设置一下模块就好了。这绝对是正确答案你不要着急去改代码代码没有问题的。

Explain the concept of a PHP session in simple terms.Apr 26, 2025 am 12:09 AM

How do you loop through all the values stored in a PHP session?Apr 26, 2025 am 12:06 AM

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.

Explain how to use sessions for user authentication.Apr 26, 2025 am 12:04 AM

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.

What are some common problems that can cause PHP sessions to fail?Apr 25, 2025 am 12:16 AM

Reasons for PHPSession failure include configuration errors, cookie issues, and session expiration. 1. Configuration error: Check and set the correct session.save_path. 2.Cookie problem: Make sure the cookie is set correctly. 3.Session expires: Adjust session.gc_maxlifetime value to extend session time.

How do you debug session-related issues in PHP?Apr 25, 2025 am 12:12 AM

Methods to debug session problems in PHP include: 1. Check whether the session is started correctly; 2. Verify the delivery of the session ID; 3. Check the storage and reading of session data; 4. Check the server configuration. By outputting session ID and data, viewing session file content, etc., you can effectively diagnose and solve session-related problems.

What happens if session_start() is called multiple times?Apr 25, 2025 am 12:06 AM

Multiple calls to session_start() will result in warning messages and possible data overwrites. 1) PHP will issue a warning, prompting that the session has been started. 2) It may cause unexpected overwriting of session data. 3) Use session_status() to check the session status to avoid repeated calls.

How do you configure the session lifetime in PHP?Apr 25, 2025 am 12:05 AM

Configuring the session lifecycle in PHP can be achieved by setting session.gc_maxlifetime and session.cookie_lifetime. 1) session.gc_maxlifetime controls the survival time of server-side session data, 2) session.cookie_lifetime controls the life cycle of client cookies. When set to 0, the cookie expires when the browser is closed.

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.
