WooCommerce HTML after short description if product is in specific category

Question

I want to show HTML text after the short description on the product page, but only on specific products that are in a specific category (categories).

I think I have to use in_category, but I can't figure out how to display the text right after the short description.

My preference is to work with a function/filter/action.

This code works:

function filter_woocommerce_short_description( $post_excerpt )   {
$your_msg='Test';
return $post_excerpt.'<br>'.$your_msg; 
};
add_filter( 'woocommerce_short_description','filter_woocommerce_short_description',10, 1 ); 

But this one works on all product pages..

Answer 1

Woocommerce's product categories are custom taxonomy terms, so you need to use the taxonomy functions (eg, has_term()) rather than WordPress' category ones.

function filter_woocommerce_short_description( $post_excerpt ) {
    global $post;
    if ( has_term( "term-name", "product_cat", $post->ID ) ) {
        $post_excerpt .= "<br/>" . "Test";
    }
    return $post_excerpt; 
};
add_filter( 'woocommerce_short_description','filter_woocommerce_short_description',10, 1 ); 

Answer 2

function filter_woocommerce_short_description( $post_excerpt ) {
global $post;
if ( has_term( "axtschlag", "product_cat", $post->ID ) || has_term( "grate-goods", "product_cat", $post->ID ) ) {
    $post_excerpt .= "<br/>" . "<strong>Pick 'n Mix actie!</strong><br> Kies & mix de merken <a href="/axtschlag">Axtschlag</a> en Grate Goods en ontvang korting! Kies je 3 tot 5 producten dan ontvang je 5% korting, kies je 6 tot 10 producten dan ontvang je maar liefst 10% korting direct in je winkelwagen. Geldt ook i.c.m. met lopende acties.";
}
return $post_excerpt; 
};
add_filter( 'woocommerce_short_description','filter_woocommerce_short_description',10, 1 );
