Recent posts on homepage: different thumbnail based on logged in status and post category

This works well on archive.php, but not working on the homepage. For some reason, the first statement doesn't get applied: if a post is in Members category and user is not logged in, it's supposed to show a default placeholder image, but instead it's still showing the actual post thumbnail.

?php if (!is_user_logged_in()  in_category('members')) { ?
    a href=?php the_permalink(); ? title=?php the_title_attribute(); ?
        img src=?php bloginfo('template_directory'); ?/img/default-login.jpg alt=?php the_title(); ? /
    /a
                                
?php } 
    else if (is_user_logged_in() || !in_category('members')) { ?                 

        a href=?php echo get_permalink($post_item['ID']) ?
            ?php echo get_the_post_thumbnail($post_item['ID'], 'news-thumb'); ?
        /a
                                    
    ?php } else { ?
            a href=?php the_permalink(); ? title=?php the_title_attribute(); ?
                img src=?php bloginfo('template_directory'); ?/img/default.jpg alt=?php the_title(); ? /
            /a

    ?php } ?

I'm using:

?php
$recent_posts = wp_get_recent_posts(array(
    'numberposts' = 6, // Number of recent posts to display
    'post_status' = 'publish' // Show only the published posts
));

foreach( $recent_posts as $post_item ) : ?

Final version so far:

?php
    $recent_posts = wp_get_recent_posts( array(
    'numberposts' = 6,        // Number of recent posts to display
    'post_status' = 'publish' // Show only the published posts
    ), OBJECT );  // 1. Set the second parameter to OBJECT.
                        
    global $post; // 2. Access the global $post variable.
        foreach ( $recent_posts as $post ) : // 3. Rename $post_item to $post
        setup_postdata( $post );         // 4. Set up global post data. ?

    else if (is_user_logged_in() || !in_category('members')) { ?                 
        a href=?php echo get_permalink($post_item['ID']) ?
            ?php echo get_the_post_thumbnail($post_item['ID'], 'news-thumb'); ?
        /a

            $content = preg_replace(~(?:\[/?)[^/\]]+/?\]~s, '', $content);  # strip shortcodes, keep shortcode content

            $trimmed_content = wp_trim_words( $content, 14, '... br /a href='. get_permalink() .'Continue reading gt;/a' );

If you want to use the the_ functions (e.g. the_permalink() and the_title()) and including in_category() (without specifying the second parameter) outside of The Loop (the standard one which calls the_post()), you should access the global $post variable and call setup_postdata() to set up global post data and after your foreach ends, call wp_reset_postdata() to restore the $post back to the current post in the main query.

You also must rename the $post_item variable to $post and I'd also use OBJECT as the second parameter value for wp_get_recent_posts(), although you could actually do setup_postdata( (object) $post ).

Working Example

$recent_posts = wp_get_recent_posts( array(
    'numberposts' => 6,        // Number of recent posts to display
    'post_status' => 'publish' // Show only the published posts
), OBJECT );  // 1. Set the second parameter to OBJECT.

global $post; // 2. Access the global $post variable.
foreach ( $recent_posts as $post ) : // 3. Rename $post_item to $post
    setup_postdata( $post );         // 4. Set up global post data.

    // ... your code here ..
    echo ( in_category( 'members' ) ? 'In' : '<b>Not</b> in' ) . ' Members category';
    the_title( '<h3>', '</h3>' );
endforeach;

wp_reset_postdata(); // 5. Restore the $post variable.

Remember, you need to change the $post_item in your code to $post and use the "arrow" to access the post data, e.g. $post->ID and not $post['ID']! :)
