Automatically add woocommerce product short description on creation - wordpress

Question

I want to add a product short description by default whenever is the new product is being created. All the products will have the same short description, so there is no point keep copying and pasting it. So it should just be there when I click on the add a new product.
I would appreciate any help.
add_filter( 'woocommerce_short_description',
'single_product_short_description', 10, 1 );
function single_product_short_description( $post_excerpt )
{
global $product;
if ( is_single( $product->id ) )
$post_excerpt = '<div class="product-message"><p>' . __( "Article only
available in the store.", "woocommerce" ) . '</p></div>' . $post_excerpt;
return $post_excerpt;
}
I found the above code but couldn't get it to work :(
Thank you.
Regards,
Emre.

Answer 1

Add this code inside your themes function.php
Change the short description content as per your need - "Here goes your short desc."
add_filter( 'wp_insert_post_data' , 'cdx_add_product_short_desc' , '99', 1 );
function cdx_add_product_short_desc( $data )
{
//only for product post type
if($data['post_type'] == 'product' ) {
//only if short description is not present
if( '' == trim($data['post_excerpt']) ):
$short_desc = 'Here goes your short desc.';
$data['post_excerpt'] = $short_desc ;
endif;
}
// Returns the modified data.
return $data;
}

This will work to automatically override anything put into a product's short description field on the front-end only. It will not add the text to the backend field itself, which is good because it keeps it globalized if you need to change it later.
add_filter( 'woocommerce_short_description', 'filter_woocommerce_short_description', 10, 1 );
function filter_woocommerce_short_description( $post_excerpt ) {
$post_excerpt = '<div class="product-message"><p>' . __( "Article only available in the store.", "woocommerce" ) . '</p></div>';
return $post_excerpt;
}
