IF 结构设计问题,乱了!
有如下需求,希望大侠指导
INPUT表单1
//用来输入文本1
//用来输入文本2
//用来提交输入的信息
我想点击了提交ida后界面输出INPUT表单2
//用来输入文本1
//用来输入文本2
//用来进一步提交输入的信息
//用来返回上一input表单1界面,但要把表单一输入的信息存储下来
当点击了提交idb后进入表单3
我想点击了提交ida后界面输出INPUT表单2
//用来输入文本1
//用来输入文本2
//用来再一次提交输入的信息
//用来返回上一input表单2界面,但要把表单二输入的信息存储下来
就输输入玩的信息,当在界面上点返回按钮时能把上一级的信息存下来,方便更改。求指导。。。。。。。。用IF结构设计的头有点大。。。
------解决方案--------------------
直接把参数通过url传啊
或者保存在session里。
url加个 step 来标识在第几步这样就行了。
------解决方案--------------------
这就是典型的ajax应用了.
A.将所有需要输入的部分 分别写在
B.默认从 第一个div 显示 当ajax提交之后 显示第二个div
C.类推B
需要掌握的内容
1.js/Jquery控制 div 的隐藏与显示
2.jquery 的 ajax 方法POST/GET

跟php没关系吧。
- HTML code
<script> function goBack(id,o){ document.getElementById(id).style.display='block'; o.parentNode.style.display='none'; } function goNext(id,o){ document.getElementById(id).style.display='block'; o.parentNode.style.display='none'; }</script>
------解决方案--------------------
保存在session里, 外加个状态, 根据请求和当前状态做状态转移和数据的session记录.

看了半天,总算搞明白你的意思了
看看这个测试例,应该是你想要的
- PHP code

PHP is widely used in e-commerce, content management systems and API development. 1) E-commerce: used for shopping cart function and payment processing. 2) Content management system: used for dynamic content generation and user management. 3) API development: used for RESTful API development and API security. Through performance optimization and best practices, the efficiency and maintainability of PHP applications are improved.

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
