在查询数据库后,根据查询结果弹出一个对话框,来选择是否继续上传资料并覆盖原来的数据,确定和取消两个按钮?我现在只能实现一个按钮,请教

给添加一个name的属性
后台根据isset($_POST['submit_button_name'])可以判断哪个按扭按下

你所说的是在表单中实现的吧?我的upload.php是一表单,表单的action转到upinfo.php中,在upinfo.php中,
if($row)//$row是查询结果{echo "<script>alert('此次上传将覆盖原文件,确定上传文件?');</script>";//只有一个确定按钮,怎样是想两个按钮呢?…………}else{…………}
...
alert当然只有一个按钮
confirm有两个按钮
echo "<script>if(confirm('此次上传将覆盖原文件,确定上传文件?')){.....};</script>";
楼主的意思我看的不是很明了,可否贴出部分代码
if($row)//$row是查询结果{echo "<script>confirm('此次上传将覆盖原文件,确定上传文件?');</script>";//只有一个确定按钮,怎样是想两个按钮呢?…………}else{…………}
echo "<script>if(confirm('此次上传将覆盖原文件,确定上传文件?')){.....};</script>";
太谢谢你了,其实我也知道有confirm这么个对话框,但是就是不会灵活运用,可能根本原因是基础不牢,太谢谢你啦
<?php#...$res = mysql_query($sql,$conn);if($res){ $form = <<<FORM <script> if(confirm('是否继续?')){ #go on... }else{ #go back... } </script>FORM echo $form;#}?>

PHP makes it easy to create interactive web content. 1) Dynamically generate content by embedding HTML and display it in real time based on user input or database data. 2) Process form submission and generate dynamic output to ensure that htmlspecialchars is used to prevent XSS. 3) Use MySQL to create a user registration system, and use password_hash and preprocessing statements to enhance security. Mastering these techniques will improve the efficiency of web development.

PHP and Python each have their own advantages, and choose according to project requirements. 1.PHP is suitable for web development, especially for rapid development and maintenance of websites. 2. Python is suitable for data science, machine learning and artificial intelligence, with concise syntax and suitable for beginners.

PHP is still dynamic and still occupies an important position in the field of modern programming. 1) PHP's simplicity and powerful community support make it widely used in web development; 2) Its flexibility and stability make it outstanding in handling web forms, database operations and file processing; 3) PHP is constantly evolving and optimizing, suitable for beginners and experienced developers.

PHP remains important in modern web development, especially in content management and e-commerce platforms. 1) PHP has a rich ecosystem and strong framework support, such as Laravel and Symfony. 2) Performance optimization can be achieved through OPcache and Nginx. 3) PHP8.0 introduces JIT compiler to improve performance. 4) Cloud-native applications are deployed through Docker and Kubernetes to improve flexibility and scalability.

PHP is suitable for web development, especially in rapid development and processing dynamic content, but is not good at data science and enterprise-level applications. Compared with Python, PHP has more advantages in web development, but is not as good as Python in the field of data science; compared with Java, PHP performs worse in enterprise-level applications, but is more flexible in web development; compared with JavaScript, PHP is more concise in back-end development, but is not as good as JavaScript in front-end development.

PHP and Python each have their own advantages and are suitable for different scenarios. 1.PHP is suitable for web development and provides built-in web servers and rich function libraries. 2. Python is suitable for data science and machine learning, with concise syntax and a powerful standard library. When choosing, it should be decided based on project requirements.

PHP is a scripting language widely used on the server side, especially suitable for web development. 1.PHP can embed HTML, process HTTP requests and responses, and supports a variety of databases. 2.PHP is used to generate dynamic web content, process form data, access databases, etc., with strong community support and open source resources. 3. PHP is an interpreted language, and the execution process includes lexical analysis, grammatical analysis, compilation and execution. 4.PHP can be combined with MySQL for advanced applications such as user registration systems. 5. When debugging PHP, you can use functions such as error_reporting() and var_dump(). 6. Optimize PHP code to use caching mechanisms, optimize database queries and use built-in functions. 7

The reasons why PHP is the preferred technology stack for many websites include its ease of use, strong community support, and widespread use. 1) Easy to learn and use, suitable for beginners. 2) Have a huge developer community and rich resources. 3) Widely used in WordPress, Drupal and other platforms. 4) Integrate tightly with web servers to simplify development deployment.
