Filtering<\/b> feature helps to sort the recordset in the data list. Using the search and filter feature, the user can easily find the relevant data from the huge number of records. The sorting or filtering functionality is very useful in the data management section of the web application. The server-side search and filter functionality can be integrated easily with PHP and MySQL.<\/p>\n
The jQuery and Ajax can be used to implement the search functionality without page refresh. It helps to make the search and filter feature user-friendly. In this tutorial, we’ll show you how to implement the search and filter feature with the server-side data using jQuery, Ajax, PHP, and MySQL.<\/p>\n
This example script provides a search and filter option on the record list. A user can be able to search some particular records in the data list from the MySQL database or filter records by the specific type (like newest records, records by ascending and descending order, records by status). This server-side search and filter in PHP are used jQuery and Ajax to do this filtering functionality without page refresh.<\/p>\n
The following functionality will be implemented to build <\/b>server-side filtering<\/b> script with PHP and MySQL.<\/p>\n
Before getting started to integrate server-side filter using PHP<\/b>, take a look at the file structure.<\/p>\n To store the data, a table is required in the database. The following SQL creates a The database configuration variables are defined in this file.<\/p>\n The User class help to connect with the database and handles the database related operations using PHP and MySQL.<\/p>\nserver_side_filter_jquery_ajax_php_mysql\/<\/span>\r\n\u251c\u2500\u2500 config.php\r\n\u251c\u2500\u2500 index.php\r\n\u251c\u2500\u2500 getData.php\r\n\u251c\u2500\u2500 User.class.php\r\n\u251c\u2500\u2500 js\/<\/span>\r\n\u2502 \u2514\u2500\u2500 jquery.min.js\r\n\u2514\u2500\u2500 css\/<\/span>\r\n \u2514\u2500\u2500 style.css\r\n<\/pre>\nCreate Database Table<\/h2>\n
