With the development of the Internet, search engines have become one of the most common ways for modern people to obtain information. In website development, adding search functionality is an essential step. One of the important components is the search box. This article will introduce how to use PHP to implement the jump page function of the search box.

1. Preliminary knowledge

Before starting this article, you need to know some basic knowledge:

PHP is a back-end programming language that can be used to process and transmit data.
HTML is a markup language used to create web pages and can be used to define the structure and content of web pages.
URL (Uniform Resource Locator) is a uniform resource locator, used to uniquely identify resources on the Internet.

2. Implementation steps

When implementing the search box jump page function, there are the following four steps:

Create an HTML file and add a search box and submit button.
Create a PHP file to receive and process the data in the search box.
Write PHP code to get the data in the search box and jump to the search results page.
Create a search results page and display the search results in it.

Below we will expand these four steps one by one.

Create HTML file

In your website pages, add a search box and submit button and combine them into a form using the form tag. The sample code is as follows:

<!DOCTYPE html>  
<html>  
<head>  
    <title>搜索框示例</title>  
</head>  
<body>  
    <h1>搜索框示例</h1>  
    <form action="search.php" method="GET">  
        <input type="text" name="q" placeholder="输入搜索关键词">  
        <input type="submit" value="搜索">  
    </form>  
</body>  
</html>

Copy after login

Create PHP file

In your project folder, create a PHP file named search.php and add the following code in it , to receive and process the data in the search box:

<?php  

if(isset($_GET['q'])){  
   //获取搜索框中的数据  
   $query = $_GET['q'];  
    
   echo "您正在搜索：" . $query;  
}  

?>

Copy after login

Write PHP code to jump to the search results page

The following code can send the user to the search box after submitting the search Jump to the corresponding search results page.

<?php  

if(isset($_GET['q'])){  
   $query = $_GET['q'];  
   header("Location: search_result.php?q=".$query);  
}  

?>

Copy after login

In the above code, we use PHP’s built-in header() function to jump to the page. Among them, the q parameter is used to pass search keywords. We will use this parameter to get the search results when jumping to the search results page.

Create search results page

In your project folder, create a PHP file named search_result.php and add the following code in it to display the search result.

<?php  

if(isset($_GET['q'])){  
   $query = $_GET['q'];  
    
   echo "搜索关键词：" . $query;  
}  

?>

Copy after login

In the above code, we will use the q parameter to obtain the search keywords and display them on the page.
