不能插入,但能更新数据
我的页面,在本地时插入和更新数据都没有问题。上传服务器后,这个页面更新数据可以,但是不能插入数据。大侠们能给个解决思路么?谢谢。
回复讨论(解决方案)
先看一下有无插入权限
您是说是空间里数据库设置的问题么?我的EDIT页面上传空间后只能更新而不能插入,login页面上传空间后也可以插入。
我的edit页面代码为
session_start () ;
include("IncDB.php");
//处理提交的修改 @allprojects @todo multi-query
@$uid=$_SESSION['id'];
if(!empty($_POST['submit'])) {
$bid=$_POST['bid'];
$bidt=addslashes($_POST['title']);
$bidl=addslashes($_POST['links']);
$result1=mysql_query("SELECT * FROM userlinks where id='$bid' and userid='".$_SESSION['id']."'",$link);
$row1=mysql_fetch_row($result1);
if($row1==null)
{
$sql ="INSERT INTO `userlinks` (`id`,`title`, `links`,`userid`,`datetime`) VALUES ('$bid','$bidt','$bidl','".$_SESSION['id']."',now());";}
else{
$sql="update userlinks set title = '$bidt' ,links = '$bidl',userid='".$_SESSION['id']."',datetime=now() where id= '$bid';";
}
if(mysql_query($sql)){
echo "<script>parent.location.reload();</script>";
}else echo "<script>parent.location.reload();</script> ";
exit();
}
$bid=addslashes($_GET['id']);
$result=mysql_query("SELECT * FROM userlinks where id ='".$bid."'and userid='$uid' order by datetime desc limit 1",$link);
@$row=mysql_fetch_row($result);
?>
红色的代码即是。我从后台添加数据后,再用update没有问题;但是不能插入。而上面这个代码在本地测试时插入和更新都没有问题。
把
if(mysql_query($sql)){
echo "<script>parent.location.reload();</script>";
}else echo "<script>parent.location.reload();</script> ";
改成
if(mysql_query($sql)){
echo "<script>parent.location.reload();</script>";
}else echo mysql_error(); //echo "<script>parent.location.reload();</script> ";
看看
因为你说本地可以,服务器不可以。所以应先检查权限
既然后台能插入,那么就应考虑是否是程序问题了
好的,我试试,谢谢!!
真牛X!又解决了。佩服佩服!

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,

Session hijacking can be achieved through the following steps: 1. Obtain the session ID, 2. Use the session ID, 3. Keep the session active. The methods to prevent session hijacking in PHP include: 1. Use the session_regenerate_id() function to regenerate the session ID, 2. Store session data through the database, 3. Ensure that all session data is transmitted through HTTPS.

The enumeration function in PHP8.1 enhances the clarity and type safety of the code by defining named constants. 1) Enumerations can be integers, strings or objects, improving code readability and type safety. 2) Enumeration is based on class and supports object-oriented features such as traversal and reflection. 3) Enumeration can be used for comparison and assignment to ensure type safety. 4) Enumeration supports adding methods to implement complex logic. 5) Strict type checking and error handling can avoid common errors. 6) Enumeration reduces magic value and improves maintainability, but pay attention to performance optimization.

The application of SOLID principle in PHP development includes: 1. Single responsibility principle (SRP): Each class is responsible for only one function. 2. Open and close principle (OCP): Changes are achieved through extension rather than modification. 3. Lisch's Substitution Principle (LSP): Subclasses can replace base classes without affecting program accuracy. 4. Interface isolation principle (ISP): Use fine-grained interfaces to avoid dependencies and unused methods. 5. Dependency inversion principle (DIP): High and low-level modules rely on abstraction and are implemented through dependency injection.

Static binding (static::) implements late static binding (LSB) in PHP, allowing calling classes to be referenced in static contexts rather than defining classes. 1) The parsing process is performed at runtime, 2) Look up the call class in the inheritance relationship, 3) It may bring performance overhead.
