get_post_meta - WordPress

Question

This code is designed to add a button to specific posts using the get_post_meta function. How do I alter the get_post_meta function to display this button on a specific post? I have already tried changing its $post->ID parameter to '1464', which is the post ID I want to use.

function custom_listify_single_job_listing_actions_after() {
    global $post;

    $url = get_post_meta( $post->ID, 'your_custom_meta_key', true );

    echo '<a href="' . esc_url( $url ) . '" class="button">My Button</a>';
}
add_filter( 'listify_single_job_listing_actions_after', 'custom_listify_single_job_listing_actions_after' );

If you only want to run this code on a specific post, you need to add an if statement to check for that post ID.

Your code would need to look similar to this:

if($post->ID == 1464){
    $url = get_post_meta( $post->ID, 'your_custom_meta_key', true );

    echo '<a href="' . esc_url( $url ) . '" class="button">My Button</a>';
}

This simply wraps the get_post_meta() function and echo statement so that both of these only run on the post you want them to. Any other post will ignore the code.
