In recent years, with the rapid development of Internet technology, more and more websites have begun to use forms to collect user information and data. In form processing, page jump is an important function. It is usually used to prompt the user whether the information submission is successful or failed, and to redirect the user to another page.
When using PHP to process forms, the jump function is very commonly used and very easy to implement. In this article, we will introduce to you how to use PHP forms to jump to the current page and make page jumps more elegant and safe.
1. Basic knowledge of form processing
When using form processing, you usually need to use HTML forms and server-side scripts to achieve it. HTML forms are used to present form elements that users can input, such as text boxes, drop-down boxes, radio buttons, multi-select boxes, etc. The server-side script is responsible for processing the data submitted by the form and storing it in the database or sending it to other applications in an appropriate manner.
PHP is a server-side scripting language that can easily process data submitted by forms and implement form submission and jump functions. When using PHP form processing, you need to set the form submission method and target address first.
2. Form submission methods
There are two form submission methods, namely "get" and "post" methods. The "get" submission method appends form data to the URL and displays it in the browser's address bar. It is suitable for passing small amounts of data. The "post" submission method includes the data in the body of the HTTP request and does not appear in the address bar. It is suitable for transferring large amounts of data and sensitive data.
When using PHP form processing, you need to specify the form submission method, using the "method" attribute. For example:
