With the continuous popularization of Internet applications, more and more websites now need to involve database operations, and PHP, as a powerful programming language, has also become one of the main tools for website development. In PHP, how to implement the functions of adding pages and jumping pages? Let me introduce it to you in detail below.

1. Add a page

It is very simple to add a page in PHP. You only need to use SQL statements to add the database according to the form information. Taking adding a user as an example, the code is as follows:

In this code, we first need to connect to the database, then obtain the data submitted by the form through$_POST, and then construct a SQL statement, Finally, use themysqli_query()function to execute the SQL statement and add the data to the database. It should be noted that before adding data, we need to verify the validity of the form data to ensure the accuracy and security of the data.

2. Page jump

After adding data, we usually need to jump the user to the specified page to prompt the user to add successfully or fail. In PHP, you can use theheader()function to achieve page jump. For example:

header("Location: success.php");

The above code redirects the user to thesuccess.phppage. It should be noted that theheader()function must be called before other output, otherwise a "header has been sent" error will occur.

3. Complete code

Based on the above introduction, we can integrate adding operations, page jumps, etc. into a complete PHP file:

     
  
添加用户
 
 
用户名：
 
密码：
 
 
   

In this code snippet , we first wrote a form to submit data to the server through the form, and then processed and added the data through PHP scripts, and performed page jumps or error prompts based on the added results. It should be noted that theheader()function must be called before other output, otherwise a "header has been sent" error will occur.

The above is an introduction to the method and process of adding page jump page jump function in PHP. I hope it can be helpful to everyone. In actual development, we also need to consider issues such as data security and page aesthetics, and constantly improve and perfect our code.
