By now i use the following functions to show the sidebar in woocommerce single-page (code from your support)
#
# wrap single product image in an extra div
#
function avia_add_image_div() {
echo "<div class='single-product-main-image alpha'>";
}
function avia_close_image_div() {
echo "</div>";
}
#
# wrap single product summary in an extra div
#
function avia_add_summary_div() {
echo "<div class='single-product-summary'>";
}
function avia_close_summary_div() {
echo "</div>"; //close out the summary
get_sidebar();
}
function avf_product_sidebar_layout_mod($layout){
if( is_single() )$layout = "sidebar_right";
return $layout;
}
add_action('init', 'ava_product_sidebar_mod');
function ava_product_sidebar_mod() {
add_action( 'woocommerce_before_single_product_summary', 'avia_add_image_div', 2 );
add_action( 'woocommerce_before_single_product_summary', 'avia_close_image_div', 20 );
add_action( 'woocommerce_before_single_product_summary', 'avia_add_summary_div', 25 );
add_action( 'woocommerce_after_single_product_summary', 'avia_close_summary_div', 3 );
add_filter( 'avf_product_sidebar_layout', 'avf_product_sidebar_layout_mod', 5);
}
