Different output depending of post or custom post type

    I am trying to realise a little script in the header, which should show a different message depending if there is a new post or a new custom post published.

    What I have so far:

    $args = array( 'numberposts' => '1', 'post_status' => 'publish' );
        $args_talks = array( 'numberposts' => '1', 'post_type' => array('talks', 'post'), 'post_status' => 'publish' );
        $recent_posts = wp_get_recent_posts( $args_talks );
        foreach( $recent_posts as $recent ){
        
       	if ( 'talks' === get_post_type() ) {
   			echo "Latest Talk from '. get_the_date('d F Y', $recent["ID"]) .':<br/><a href="' . get_permalink($recent["ID"]) . '">'. get_the_title( $recent["ID"] ) .'</a>'";
   		} else {
        	echo 'Latest News from '. get_the_date('d F Y', $recent["ID"]) .':<br/><a href="' . get_permalink($recent["ID"]) . '">'. get_the_title( $recent["ID"] ) .'</a>';
   			 }
        }

    I am aware that the last “if else” part is wrong, but it should illustrate what I am trying to achieve. Or maybe I’m doing something fundamentally wrong.

    In any case I would be grateful for any help!

    The first line, setting $args, is not needed (the variable is not used).
    Read about the wp_get_recent_posts function here: https://developer.wordpress.org/reference/functions/wp_get_recent_posts/
    It says that the default return is an array, so when you use the result, you need to reference inside the array for the post ID to pass to get_post_type like you did for get_the_date.

    You’re right, I forgot to delete the $args line, that came from a test with two variables. And thanks for the hint with the wp_get_recent_posts function! Maybe I can figure out how to realise it. For non-developers like me the official documentation is a bit cryptic. We’ll see. Thanks a lot anyway!

    Wait, there’s more! 🙂 You’re running a simple PHP loop and not the formal WP “The Loop®” which iterates several global values behind the scene. This means template functions like get_the_*() which rely upon these globals will not work correctly without some extra help. Help by using setup_postdata() within your loop. It performs a similar function to the_post() used in “The Loop®”.

    Don’t forget to do global $post; within scope of your code anytime you use setup_postdata().

    You shouldn’t need the global variables or the standard loop, because the data is in the array, and all the functions being called take a post ID as a parameter.

    Indeed, I didn’t look close enough. Apologies for any confusion.

    Thanks a lot for your help! I think I got in the right direction, also to understand the Loop a litte bit better. As suggested I read the post type with get_post_type and put it in a variable, then read it out with a if/else statement. And it seems to work! Here’s the final code:

    $args = array( 'numberposts' => '1', 'post_type' => array('talks','post') , 'post_status' => 'publish', 'orderby' => 'date' );
$recent_posts = wp_get_recent_posts( $args );
foreach( $recent_posts as $recent ){
$post_type = get_post_type($recent["ID"]);
if ($post_type == 'talks') {
echo 'Latest Talk from '. get_the_date('d F Y', $recent["ID"]) .':<br/><a href="' . get_permalink($recent["ID"]) . '">'. get_the_title( $recent["ID"] ) .'</a>';
} else {
echo 'Latest News from '. get_the_date('d F Y', $recent["ID"]) .':<br/><a href="' . get_permalink($recent["ID"]) . '">'. get_the_title( $recent["ID"] ) .'</a>';
}
}

    I am very aware that the code can be beautified or simplified. For now, however, what counts is that it works, thanks to your help!
