写代码为什么总是出现这种奇怪的现象?
之前代码里有一句alert(发布成功)这样的话 我明明已经删除了 为什么还是弹出来这个呢
还有我写好的页面为了备份 把写好的1.php和2.php的代码都复制出来然后再新建5.php和6.php文件复制进去 为什么6.php里面我写的跳转页面还是跳到1.php里面呢 我明明写的是跳转到5.php啊 这是为什么啊 老是这样 真是气死了 谁能帮帮我啊
回复讨论(解决方案)
这是代码 大家帮我看看 明明写的由6.php跳到5.php 却每次跳到一个不相关的3.php上面
5.php
header ( " Pragma: no-cache " );
$pdo=new PDO("mysql:host=localhost;dbname=t1","root","");
$sth=$pdo->query('select * from blog2');
$result = $sth->fetchall(PDO::FETCH_ASSOC);
foreach($result as $v){
echo $v['type'];
echo $v['content'];
};
?>
6.php 如下
header ( " Pragma: no-cache " );
$pdo=new PDO("mysql:host=localhost;dbname=t1","root","");
$pdo->exec("INSERT INTO blog2 (type,name,num,content) VALUES ('$_POST[select]','$_POST[name]','$_POST[num]','$_POST[content]')");
header("location:http://localhost/blog5.php");
?>
是不是有缓存。
看代码没有问题。
echo $v['type'];
echo $v['content'];
这里会不会有js代码,所以执行了?

对缓存不懂啊 我把3.php的页面删除了 现在提交内容后跳转地址又变成了blog.php了 真是奇怪
换个浏览器看看
换个浏览器看看
换了四个浏览器 还是这样
而且我提交后 我查看数据库里面 并没有数据插入进去
6.php跳转的是blog5.php啊。你文件名到底叫什么?
6.php跳转的是blog5.php啊。你文件名到底叫什么?
文件名没错 就是blog5.PHP 不是5.PHP 我只是举例子
从5就没有跳转到6 如果跳转了不可能数据库没有东西

In PHP, password_hash and password_verify functions should be used to implement secure password hashing, and MD5 or SHA1 should not be used. 1) password_hash generates a hash containing salt values to enhance security. 2) Password_verify verify password and ensure security by comparing hash values. 3) MD5 and SHA1 are vulnerable and lack salt values, and are not suitable for modern password security.
