Redirect no product url's to static url

Question

I am trying to redirect non-existing woocommerce product's url's to worpdress page.

Example:

https://testname.com/product/abc to https://testname.com/sample-page

here there is no product published as abc.

also i have few working products at https://testname.com/product/def.

i tried with .htaccess but looks like it's not possible to use .htaccess in this case.

Thanks in advance.

If you prefer more control in coding, you may use

• request hook - test the WordPress query after it is being setup
• preg_match() - match /product/ keyword
• url_to_postid() - test if product url exists

to build a checking when WordPress query is being setup. The advantage of code against .htaccess is that it is relatively server independent such as server migration, site migration and so on.

The following code is placed in theme functions.php and proved to work in a testing site.

add_filter( 'request', 'ws365986_check_request' );
function ws365986_check_request( $query ) {
    // var_dump($_SERVER['REQUEST_URI']); // for debug

    // only check for product url if /product/ is found in URL
    if( isset( $_SERVER['REQUEST_URI'] ) && preg_match( '/\/product\//', $_SERVER['REQUEST_URI'], $matches ) ) {
        // check if url product exist
        if( empty( url_to_postid( $_SERVER['REQUEST_URI'] ) ) ) {
            // redirect if return is 0 (empty)

            $url = home_url( '/sample-page' );
            // wp_redirect( $url ); // because $url is prepared by internally, wp_redirect should be enough
            wp_safe_redirect( $url );
            exit(); // exit script after redirect
        }
    }

    // default
    return $query;
}

It is possible with the .htaccess file, add the below rule in the .htaccess:

Redirect 301 https://testname.com/product/abc https://testname.com/sample-page

or

Redirect 301 /product/abc /sample-page
