PHP的mysql插入请求返回无报错,但数据库未更新
有下面这段PHP代码
$query = "insert into index_base (cardid, name, sex, nationality, birth, address, issued, expiration) values ($cardid, $name, $gender, $folk, $birthday, $addr, $agency, $expire)";mysql_query($query);if($buy=="1"){ $bid = mysql_insert_id();echo($bid); $time=date("Y-m-d",time()); $time.=":1"; $query = "insert into index_b2a (bid, aid, `limit`, now) values ($bid, $aid, '$time', 1)";echo($query); $result = mysql($query); echo("result 为".$result); if(mysql_affected_rows()==1)die("1"); else die("0");}
根据echo和die返回的值来看,请求 $query = "insert into index_b2a (bid, aid, `limit`, now) values ($bid, $aid, '$time', 1)";应该是完全没错,$result为1,且affected rows也是1。
但是在数据库里,怎么也找不到插入的这一条在哪里。
我加了一个echo($query),打印出来的请求为insert into index_b2a (bid, aid, `limit`, now) values (102631, '89', '2014-06-13:1', 1),直接输入mysql,当然也是执行正确的,并且刷新数据库后,立刻能看到插入的条目。
因为limit是关键字,我已经加了``作为引号。
为了确保不会造成错误,89外面的引号也去掉,2014-06-13:1这个值也改了,把后面冒号和数字1去掉。
然后执行:
仍然是mysql里面能生效,php里面不生效,但返回值都说是执行成功。
不知道问题出在哪里?
回复讨论(解决方案)
$result = mysql($query); 中的mysql() 是你自定义的函数么?还是手误?
echo mysql_error(); 看看有没有错误。
是不是入错库了?
$result = mysql($query); 这个是什么?
我也遇到同样的问题,insert 、 update都无法完成。
我也遇到同样的问题,insert 、 update都无法完成。
查了查去也没发现什么,最后弄了一个MySql API文档,找了段代码,更改相应字段就好了。应该是语句字符的问题吧(我也不知道。。。)。
附上我的能insert的代码,你修改内容了试试,希望能解决你的问题:
$sql="insert into resell_info (id, user, datetime, content) values (null,'12345',null,'12345')"; mysql_query($sql);
mysql_query()函数的第二个参数最好也加上
贴出程序的运行结果
学习,学习,学习
mysql_query(query,connection);
肯定是你没有连接上数据库了。
在mysql里面测,能成功,那说明语句没有问题。但是mysql里面测,其实是在已经链接数据库的状态下进行。
但在php页面,首先你要做的就是先连接数据库,补充connection参数。

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,
