php - Auto text woocommerce_short_description hook -

i trying create automatic text in description of woocommerce articles , put "article available in store."

i thought putting inside function this:

add_filter ('woocommerce_short_description', 'in_single_product', 10, 2);  function in_single_product () {     echo '<p> my-text-here </ p>'; } 

but text not appear in front-end. appears if put text on back-end.

does know why happens?

the correct syntax writing add_filter

// define my_editor_content   function my_editor_content( $post_excerpt )   {       // make filter magic happen here...     return $post_excerpt; }; // add filter add_filter( 'woocommerce_short_description','my_editor_content',10, 1 ); 

well, use code in functions.php of child theme.

function my_editor_content( $post_excerpt ) { $content = 'the default text, imposed me, needs here in every product.'; return $content.'<br>'.$post_excerpt; }  add_filter('woocommerce_short_description', 'my_editor_content', 10, 1); 

i hope you.
