How to use PHP and Vue to implement data search function

In modern web development, data search function has become a very common and essential function. PHP and Vue are two very popular technologies. If you combine their powerful capabilities, you can quickly implement an efficient data search function.

This article will introduce how to use PHP and Vue to implement the data search function through specific code examples. We will take a simple student information management system as an example. There is a student information table in the system, which contains information such as the student's name, age, and gender. We need to implement a search form so that users can search for student information by entering keywords.

First, we need to create a PHP backend interface to handle the search function. We can use PHP's database operation extensions, such as PDO or mysqli, to connect to the database and perform query operations. The following is a code example using PDO extension:

prepare($sql); $stmt->bindValue(':keyword', '%' . $keyword . '%'); // 执行查询 $stmt->execute(); // 获取结果集 $results = $stmt->fetchAll(PDO::FETCH_ASSOC); // 返回 JSON 格式的结果 echo json_encode($results); ?>

In the above code, we first establish a connection with the database, and then obtain the keywords entered by the user from the front end. Next, we use prepared statements to prevent SQL injection and execute the query, returning the query results to the front end in JSON format.

Next, we need to use Vue on the front end to handle the search function. The following is a code example using Vue:

      
  
  搜索 
 
{{ student.name }}
 
 
   

In the above code, we first introduced Vue.js and created a Vue instance. Two variables,keywordandstudents, are defined indataof the instance, which are used to save the keywords and query results entered by the user respectively. In thesearchmethod, we use thefetchmethod to send an Ajax request to the backend interface, and assign the returned data to thestudentsvariable.

Through the above code examples of PHP and Vue, we have implemented a simple data search function. After the user enters the keyword in the input box and clicks the search button, the matching student information can be obtained from the backend and displayed on the page.

The above is just a simple example. In actual development, the code can be further optimized and expanded according to specific needs. I hope this article can help you understand how to use PHP and Vue to implement data search functions!
