我这个代码为什么提交什么数据都插入到数据的内容都一样呢?
不管提交什么数据都是插入图片里面的内容 也就是把name自身插入进去了 没有把name的值插进去 这是为什么?
我在2.php上试了一下 这样
print_r($_POST);
exit();
$pdo=new PDO("mysql:host=localhost;dbname=t1","root","");
.....
为什么还是把原来的东西插入进去了 还是没变化 这是为什么
这是1.php
$db = new PDO('mysql:host=localhost;dbname=t1', 'root', '',array(PDO::MYSQL_ATTR_INIT_COMMAND => "SET NAMES 'utf8'"));
$rs = $db -> prepare("select * from `baidu`;");
$rs -> execute();
$list = $rs -> fetchAll(PDO::FETCH_ASSOC);
?>
foreach($list as $v){
echo $v['type'].'
';
echo $v['name'].'
';
echo $v['num'].'
';
echo $v['site'].'
';
echo $v['content'].'
';
}
?>
这是2.php
$pdo=new PDO("mysql:host=localhost;dbname=t1","root","");
if($pdo->exec("INSERT INTO baidu(
type,
name,
num,
site,
content
)
VALUES ('{$_POST['select']}','{$_POST['name']}','{$_POST['num']}','{$_POST['site']}','{$_POST['content']}')"){
echo "<script>alert('发布成功');location='1.php';</script>";
}
?>
回复讨论(解决方案)
2.php 代码都是错误的 if那少右括号
然后你mysql打印出来的数据是之前的
你这里根本就没执行成功
你的2.php错误, 你是想要插入成功之后弹出一个提示吧。
还在纠结这个问题啊。
上次不是说了,你SQL语句拼接得不对。
字符串和变量的拼接有问题,这是基础知识,你得好好补补:
$str = "This is string '". $_POST['name'] . "' some string ";

不少右括号啊
把if去掉,php执行顺序是从上到下,你为什么要加if ,判断结果是否插入成功也不是这么判断的吧
如果还不对,你在把所有的这些 ('{$_POST['select']}','{$_POST['name']}','{$_POST['num']}','{$_POST['site']}','{$_POST['content']}')")
post取得的值 手动写上 比如 1 2 3 4 5 ,看看是否能插入 如果还是不能,那就说明前面的
$pdo=new PDO("mysql:host=localhost;dbname=t1","root","");
$pdo->exec 这些错了,一点一点排错呗。

$pdo=new PDO("mysql:host=localhost;dbname=t1","root","");if($pdo->exec("INSERT INTO baidu(type,name,num,site,content)VALUES ('{$_POST['select']}','{$_POST['name']}','{$_POST['num']}','{$_POST['site']}','{$_POST['content']}')") {echo "<script>alert('发布成功');location='1.php';</script>";}
$pdo=new PDO("mysql:host=localhost;dbname=t1","root","");
if($pdo->exec("INSERT INTO baidu(

num,

)
VALUES ('{$_POST['select']}','{$_POST['name']}','{$_POST['num']}','{$_POST['site']}','{$_POST['content']}')")
{
echo "<script>alert('发布成功');location='1.php';</script>";
}
颜色不会编辑 左括号4个 右括号3个、、、
f($pdo->exec("INSERT INTO baidu(
type,
name,
num,
site,
content
)
VALUES ('{$_POST['select']}','{$_POST['name']}','{$_POST['num']}','{$_POST['site']}','{$_POST['content']}')") ){
少了个 ),你的程序有语法错误,不会被执行!
如果程序能正常执行,只是写入库的数据有问题,那就输出SQL语句看看是什么样的。
f($pdo->exec("INSERT INTO baidu(
type,
name,
num,
site,
content
)
VALUES ('{$_POST['select']}','{$_POST['name']}','{$_POST['num']}','{$_POST['site']}','{$_POST['content']}')") ){
少了个 ),你的程序有语法错误,不会被执行!
还是不行
f($pdo->exec("INSERT INTO baidu(
type,
name,
num,
site,
content
)
VALUES ('{$_POST['select']}','{$_POST['name']}','{$_POST['num']}','{$_POST['site']}','{$_POST['content']}')") ){
少了个 ),你的程序有语法错误,不会被执行!
我都不知道为什么我把2.php里面alert那句话删了 为什么还是弹出来提示框来
那就是你还有个 2.php

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 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.

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.
