Feature Request: Add “Plugin Size” Column to the Plugins Page

Requesting the addition of a “Size” column to the WordPress Plugins admin page to provide users with detailed insights into the storage footprint of each installed plugin.Proposed Functionality

1. New Column for Plugin Size
   Introduce a custom “Size” column to display the total size of each plugin’s directory in human-readable format (e.g., KB, MB).
2. Column Data Calculation
   • Use the server’s file system to calculate the total size of each plugin directory within the wp-content/plugins directory.
   • Display the calculated size in the new column using appropriate formatting.
3. Custom Styling
   • Adjust the column width to fit the content properly (e.g., 7rem width).
   • Ensure the column aligns seamlessly with existing columns in the admin interface.

Benefits

• Transparency: Provides administrators with a quick overview of how much disk space each plugin consumes.
• Efficiency: Helps identify resource-heavy plugins that may require optimization or removal.
• User Experience: Enhances the Plugins page with actionable information that improves site management.

Mock Implementation

• Add a new column using the manage_plugins_columns filter.
• Populate the column with the calculated size using the manage_plugins_custom_column action.
• Include a helper function to calculate the folder size using PHP’s RecursiveDirectoryIterator.
• Add lightweight CSS directly to the Plugins page to ensure proper alignment and display.

Example Code

function custom_plugins_columns( $columns ) {
    $columns['plugin_size'] = __( 'Size', 'text-domain' );
    return $columns;
}
add_filter( 'manage_plugins_columns', 'custom_plugins_columns' );

function custom_plugins_column_content( $column_name, $plugin_file ) {
    if ( 'plugin_size' === $column_name ) {
        $plugin_dir = WP_PLUGIN_DIR . '/' . dirname( $plugin_file );
        $size_in_bytes = folder_size( $plugin_dir );
        $size = size_format( $size_in_bytes );
        echo esc_html( $size );
    }
}
add_action( 'manage_plugins_custom_column', 'custom_plugins_column_content', 10, 2 );

function folder_size( $dir ) {
    $size = 0;
    if ( is_dir( $dir ) ) {
        foreach ( new RecursiveIteratorIterator( new RecursiveDirectoryIterator( $dir, FilesystemIterator::SKIP_DOTS ) ) as $file ) {
            $size += $file->getSize();
        }
    }
    return $size;
}

function custom_plugins_page_styles() {
    echo '<style>.column-plugin_size { width: 7rem; }</style>';
}
add_action( 'admin_head', 'custom_plugins_page_styles' );
