    Hi and thanks in advance for any help.

    I am running this basic query in my loop file to output one post from each category and sub-category:

    Code in pastebin: http://pastebin.com/srwgpWN6

    And so on for about 20 categories.

    The issue is the posts are sometimes in multiple categories and this is causing duplicates on the homepage. What can I add to stop this duplication?

    Thanks again.

    Matt

    the method to avoid duplicate posts in multiple looops is described here (the ‘array’ method after the ‘Note for Multiple Posts in the First Category’ headline): http://codex.wordpress.org/The_Loop#Multiple_Loops_in_Action

    do you have the code to show all your categories with one post?

    Hi,

    That is the page I was (trying) to follow instructions on by using:

    $do_not_duplicate = $post->ID;

    I understand I am probably using it incorrectly as I am not much good at PHP. I want to show the latest post from each category and sub category. As you can see currently on my homepage – http://www.manchesterfinest.com there are a lot of duplicates. I am trying to eradicate these. So if a post has already been displayed then it appears in another category, it will be skipped over and the next newest will be shown.

    I hope that makes sense.

    A longer pastebin is here: http://pastebin.com/KeiYZWm2

    Thank you

    I particularly pointed to the ‘array method’ – have you read the linked codex chapter and tried to implement it?

    here is a partly corrected section of your code, to show the principle:

    Thank you I will give this a go and get back to you, with good or not as good news.
