yes, done ??

hello, yes, it totally worked, I just had to add a “)” in the second line of code, it was like this:

function crp_custom_wp_query($query) {
    if(is_singular('product') && $query->get( 'crp_query')){
        $query->set('post_type', 'product');
        $meta_query = [
            'relation' => 'AND',
            [
                'key' => '_stock_status',
                'value' => ['instock','onbackorder'],
                'compare' => 'IN',
            ]
        ];
        $query->set('meta_query', $meta_query);
    }

    return $query;
}
add_filter('pre_get_posts', 'crp_custom_wp_query', 100);

Thank you very much ??

I determine if it’s in stock or not when I create or edit a product, it’s the same as a post but it’s a woocommerce product.

maybe this code above, from another related plugin can help

function yarpp_custom_wp_query($query) {
    if(isset($query->yarpp_cache_type)){
        $query->set('post_type', 'product');
        $meta_query = [
            'relation' => 'AND',
            [
                'key' => '_stock_status',
                'value' => ['instock','onbackorder'],
                'compare' => 'IN',
            ]
        ];
        $query->set('meta_query', $meta_query);
    }

    return $query;
}
add_filter('pre_get_posts', 'yarpp_custom_wp_query', 100);
