Add custom meta data for products

Finally, i succeeded by going through the child theme file “functions.php” :

// Display Fields

add_action( 'woocommerce_product_options_general_product_data', 'woo_add_custom_general_fields' );

// Save Fields

add_action( 'woocommerce_process_product_meta', 'woo_add_custom_general_fields_save' );

function woo_add_custom_general_fields() {

global $woocommerce, $post;

// Text Field

woocommerce_wp_text_input(

    array(

        'id' => 'barcode',

        'label' => __( 'Code Barre', 'woocommerce' ),

        'placeholder' => 'code barre',

        'desc_tip' => 'true',

        'description' => __( 'Product barcode.', 'woocommerce' )

    )

);

}

function woo_add_custom_general_fields_save( $post_id ){

// Textarea

$woocommerce_barcode = $_POST['barcode'];

if( !empty( $woocommerce_barcode ) )

    update_post_meta( $post_id, 'barcode', esc_html( $woocommerce_barcode ) );

}
