WordPress show a post for each category

    Hi all

    I have searched for this, but all I found was a way to display posts by category.

    I have modified the script to show the title of one post per category. But it only shows a post for the first five categories!

    (I know I am doing this wrong. I should be searching for all categories, and then for each category, find the most recent post… but the script I found was for putting posts into categories… and I modified that.)

    So far I have:

    <div>
    <?php
    /* start of The Loop, Display by Category style */
    if (have_posts()) :
    ?>
    <?php
    /* collect categories */
    foreach($posts as $post) :
    $category = get_the_category();
    $cats[$category[0]->cat_ID] = $category[0]->cat_name;
    endforeach;

    /* uncomment next line to have categories sort alphabetically */
    // uasort($cats, strcasecmp);

    $cats = array_flip($cats);
    ?>
    <?php
    /* start of 'display by category' loop */
    foreach($cats as $current_cat) :
    $ItemCount = $Items;
    if ($CatItem == 0 ) {
    ?>
    <div class="item1">
    <div><a class="shade" style="font-weight:bold;" href="<?php echo get_category_link($current_cat); ?>" title="View all posts in <?php echo get_the_category_by_id($current_cat); ?>"><?php echo get_the_category_by_id($current_cat); ?></a></div>
    <?php
    /* post loop for each category listing */

    foreach($posts as $post) :
    the_post();
    $category = get_the_category();
    if($current_cat == $category[0]->cat_ID) : // if post is in correct category
    if ($ItemCount != $ItemPosts ) {?>
    <div class="post" id="post-<?php the_ID(); ?>"> <a href="<?php the_permalink() ?>" title="Permanent Link to <?php the_title(); ?>">
    <?php the_title(); ?>
    </a> </div>
    <?php $ItemCount = ItemCount + 1; }
    endif; // end 'if post in correct category'
    endforeach; // end post loop
    $CatItem = 1;
    } else {
    ?>
    <div class="item2">
    <div><a class="shade" style="font-weight:bold;" href="<?php echo get_category_link($current_cat); ?>" title="View all posts in <?php echo get_the_category_by_id($current_cat); ?>"><?php echo get_the_category_by_id($current_cat); ?></a></div>
    <?php
    /* post loop for each category listing */

    foreach($posts as $post) :
    the_post();
    $category = get_the_category();
    if($current_cat == $category[0]->cat_ID) : // if post is in correct category
    if ($ItemCount != $ItemPosts ) {?>
    <div class="post" id="post-<?php the_ID(); ?>"> <a href="<?php the_permalink() ?>" title="Permanent Link to <?php the_title(); ?>">
    <?php the_title(); ?>
    </a> </div>
    <?php $ItemCount = ItemCount + 1; }
    endif; // end 'if post in correct category'
    endforeach; // end post loop

    $CatItem = 1;
    }
    ?>
    </div>
    <?php
    rewind_posts(); // reset loop for next category
    endforeach; // end 'display by category' loop
    ?>
    <?php endif; // end of The Loop, organized by category style
    ?>

    hmmm… not got any replies. I’ll guess the coe above put people off!

    What I want to do is simple really:

    1. Find all the categories.
    2. For each category find latest post.
    3. Print the category title followed by the title of the post.

    The code above (just ignore it) is the other way around: It finds latest posts and then sorts them into categories.

    I have not been able to find out how to find all categories. there is list_cats, but that just prints all categories instead of putting them in a variable to use…

    To list 1 post from category use:

    <ul>
    <?php
    $posts =get_posts('numberposts=1&offset=1&category=4');
    foreach($posts as $post) :
    ?>
    <li><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></li>
    <?php endforeach; ?>
    </ul>

    Now I just need to add something before that to search for a category, and then automatically place it in the category= bit… any ideas?

    I have got a working version now!

    I will post a simplified version of what I have done (so as not to scare people away; in my code I have a hackish loop to divide the categories into two columns…)

    <?php$categories = array(1, 2, 3, 4,);
    foreach($categories as $categ){
    setup_postdata($post);
    $posts = get_posts('numberposts=1&category='.$categ);
    foreach($posts as $post) :
    ?>
    <div><?php the_category(', ') ?>
    <li><a href="<?php the_permalink(); ?>" title="Link to <?php the_title(); ?>"><?php the_title(); ?></a></li></div>

    <?php endforeach;
    }?>
