模拟管理系统出现以下问题:
数据库名:empman 里面有两张表:admin 和 emp 其中admin中字段:id name password
现有代码:
login.php文件:
if(!empty($_GET['errno']))
{
$errno=$_GET['errno'];
if($errno==1)
{
echo "
你的用户名或密码错误!";
}
}
?>
loginProcess.php文件:
//用户id
$id=$_POST['id'];
//用户密码
$password=$_POST['pwd'];
//连接数据库
$conn=mysql_connect("localhost","root","root");
if(!$conn)
{
die("连接失败".mysql_errno());
}
mysql_query("set name utf8",$conn) or die(mysql_errno());
mysql_select_db("empman",$conn) or die(mysql_errno());
$sql="select password from admin where id=$id";
$res=mysql_query($sql,$conn);
if($row=mysql_fetch_assoc($res))
{
if($row['password']== md5($password))
{
header("Location:empManage.php");
exit();
}
}
header("Location:login.php?errno=1");
exit();
mysql_free_result($res);
mysql_close($conn);
}
现象:在login页面中输入正确id和密码后什么都不显示 直接跳到loginProcess.php页面了,找不到问题所在,请大家指教。
回复讨论(解决方案)
表单提交后是会跳转的,如果不想跳转请使用ajax
如果不连数据库是可以正常跳转的,连入数据库后验证id和密码后就不正常跳转了 ,不知问题所在

What’s still popular is the ease of use, flexibility and a strong ecosystem. 1) Ease of use and simple syntax make it the first choice for beginners. 2) Closely integrated with web development, excellent interaction with HTTP requests and database. 3) The huge ecosystem provides a wealth of tools and libraries. 4) Active community and open source nature adapts them to new needs and technology trends.

PHP and Python are both high-level programming languages that are widely used in web development, data processing and automation tasks. 1.PHP is often used to build dynamic websites and content management systems, while Python is often used to build web frameworks and data science. 2.PHP uses echo to output content, Python uses print. 3. Both support object-oriented programming, but the syntax and keywords are different. 4. PHP supports weak type conversion, while Python is more stringent. 5. PHP performance optimization includes using OPcache and asynchronous programming, while Python uses cProfile and asynchronous programming.

PHP is mainly procedural programming, but also supports object-oriented programming (OOP); Python supports a variety of paradigms, including OOP, functional and procedural programming. PHP is suitable for web development, and Python is suitable for a variety of applications such as data analysis and machine learning.

PHP originated in 1994 and was developed by RasmusLerdorf. It was originally used to track website visitors and gradually evolved into a server-side scripting language and was widely used in web development. Python was developed by Guidovan Rossum in the late 1980s and was first released in 1991. It emphasizes code readability and simplicity, and is suitable for scientific computing, data analysis and other fields.

PHP is suitable for web development and rapid prototyping, and Python is suitable for data science and machine learning. 1.PHP is used for dynamic web development, with simple syntax and suitable for rapid development. 2. Python has concise syntax, is suitable for multiple fields, and has a strong library ecosystem.

PHP remains important in the modernization process because it supports a large number of websites and applications and adapts to development needs through frameworks. 1.PHP7 improves performance and introduces new features. 2. Modern frameworks such as Laravel, Symfony and CodeIgniter simplify development and improve code quality. 3. Performance optimization and best practices further improve application efficiency.

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values and handle functions that may return null values.
