How can I get current version of custom plugin in wordpress

4 comments

1. You can use get_file_data() function which is available on frontend and backend. For example:

   get_file_data('/some/real/path/to/your/plugin', array('Version'), 'plugin');
   

2. if you use get_plugin_data() on the frontend it will throw an error Call to undefined function get_plugin_data(). Here is the correct way to get plugin header data.

   if ( is_admin() ) {
       if( ! function_exists( 'get_plugin_data' ) ) {
           require_once( ABSPATH . 'wp-admin/includes/plugin.php' );
       }
       $plugin_data = get_plugin_data( __FILE__ );
   
       echo "<pre>";
       print_r( $plugin_data );
       echo "</pre>";
   }
   

3. You could save you version in the options table for easy retrieval. But you can also use get_plugin_data for more details about a given plugin.

   <?php
   
       $data = get_plugin_data( "akismet/akismet.php", false, false );
   
   ?>
   

   Please note that get_plugin_data is only available in the WordPress admin, it’s not a front-end available function.

4. For users who land on this question to find out the current version of WordPress itself use this function.

   // it will show only numeric value i.e 5.8.2
   echo get_bloginfo( 'version' );
