Shortcode To Display Post Custom Field Value Inside Excerpt

Question

I want to create a shortcode that pulls value from a custom field of a post and returns that value inside excerpt.

I already have a function for the custom value:

function geo_name_function( $atts ) {

    $atts = shortcode_atts( array(
        'post_id' => get_the_ID(),
    ), $atts, 'geo_name' );

    return get_post_meta( $atts['post_id'], 'field_name', true );
}

add_shortcode('geo_name', 'geo_name_function');

And filter for the title:

add_filter( 'the_title', function( $geo_name_function ) {
    return do_shortcode( $geo_name_function );
});

add_filter( 'the_title', 'se385007_title_filter', 20, 2 );
function se385007_title_filter( $title, $post_id ) 
{
    $new_title = str_replace( "[geo_name]", "[geo_name post_id=$post_id]", $title );
    return do_shortcode( $new_title );
)

I thought that by adding the Excerpt filter:

add_filter( 'oceanwp_excerpt', 'do_shortcode');

It will fix it but it did not.

I tried adding few other filters but just ended up breaking WordPress ).

At the moment if Custom Value is Ice Cream. If my excerpt is Favorite [geo_name] it only returns Favorite.

Please assist!

Even though this is specific for OceanWP, the solution is plain Wordpress.

Add these two lines to the end of your functions.php to render the shortcodes in both the_excerpt() and get_the_excerpt().

add_filter( 'the_excerpt', 'do_shortcode' );
add_filter('get_the_excerpt', 'do_shortcode');
