    Hi,

    You proposal is returning a “Sorry, no posts were found.” message.

    BUT, I tried to replace $cat = $cats[0]; with $cat = $cats[1]; and it’s working. I didn’t know that [O] was Category (first level) and [1] was Sub-Category (second level).

    Problem now is that if posts are just in first level, it’s returning a “Sorry, no posts were found.” message.

    Would it be possible to say “Look in $cats[1] but if there is nothing in there then look in $cats[0]” ?

    Or “look in $cats[1 and O] in this order” (priority to 1)

    Hmm, what about this?:

    if ( is_single() ) {
    $cat =  get_the_category();
} else {
    $cat = get_category( get_query_var( 'cat' ) );
}

    If that doesn’t work, we may be able to loop through them all and build our own array of categories.

    Hi Tom,

    This is not working, returning a “no found” message.

    Ok, let’s try this:

    if ( is_single() ) {
    $cat = array();

    $cats =  get_the_category();

    foreach ( $cats as $cat ) {
        $cat[] = $cat->slug;
    }
} else {
    $cat = get_category( get_query_var( 'cat' ) );
}

    Hi,

    This is provoquing a critical error.

    We agree that the entire function would be like this ?

    <?php if ( is_single() ) {
    $cat = array();

    $cats =  get_the_category();

    foreach ( $cats as $cat ) {
        $cat[] = $cat->slug;
    }
} else {
    $cat = get_category( get_query_var( 'cat' ) );
}

$cat_slug = $cat->slug;
$list = get_page_by_title( 'related', 'OBJECT', 'wp_show_posts' );
wpsp_display( $list->ID, 'tax_term="' . $cat_slug . '"' );
?>

    Try this:

    <?php if ( is_single() ) {
    $cat_values = array();

    $cats =  get_the_category();

    foreach ( $cats as $cat ) {
        $cat_values[] = $cat->slug;
    }
} else {
    $cat_values = get_category( get_query_var( 'cat' ) );
}

$cat_slug = implode( ', ', $cat_values );
$list = get_page_by_title( 'related', 'OBJECT', 'wp_show_posts' );
wpsp_display( $list->ID, 'tax_term="' . $cat_slug . '"' );
?>

    Hi Tom,

    It’s not working, it’s breaking my layout and displaying a “critical error” message where WPSP is supposed to display.

    What’s the error, exactly?

    Using WPSP like this does take some tweaking, as it wasn’t built for it by default.

    Hi Tom,

    Unfortunately this snipet is displaying posts from category but not from sub-category.

    Can you share the debug data with this change?

    Hi Tom,

    Here you go :

    array(7) { ["order"]=> string(3) "ASC" ["orderby"]=> string(6) "parent" ["post_type"]=> string(4) "post" ["posts_per_page"]=> int(4) ["post_status"]=> array(1) { [0]=> string(7) "publish" } ["tax_query"]=> array(1) { [0]=> array(4) { ["taxonomy"]=> string(8) "category" ["field"]=> string(4) "slug" ["terms"]=> array(2) { [0]=> string(6) ""andes" [1]=> string(10) "santander"" } ["operator"]=> string(2) "IN" } } ["post__not_in"]=> array(1) { [0]=> int(22765) } }

    So that means the list is now looking for posts in the “andes” and “santander” categories.

    Things get pretty complex once you start checking for parent/child categories, which is why related post plugins are much better suited for this kind of thing.

    Is “santander” a child category within the “andes” category?

    Hi Tom,

    Yes, “santander” a child category within the “andes” category
