  • Example of simple loop using category__in to return posts for category ids 4,6, and 30 (or use tag__in):

    <?php
    $args=array(
      'category__in' => array(4,6,30),
      'post_type' => 'post',
      'post_status' => 'publish',
      'posts_per_page' => -1,
      'caller_get_posts'=> 1
    );
    $my_query = null;
    $my_query = new WP_Query($args);
    if( $my_query->have_posts() ) {
      echo 'List of Posts';
      while ($my_query->have_posts()) : $my_query->the_post(); ?>
        <p><a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to <?php the_title_attribute(); ?>"><?php the_title(); ?></a></p>
        <?php
      endwhile;
    }
    wp_reset_query();  // Restore global post data stomped by the_post().
    ?>

    Thanks for your reply. Forgive me, I am a quasi-newbie.
    I have quickly read the documentation you linked.
    Can you tell me in which template I have to insert your php code? Or (I suppose equivalently) which is the template which displays all the posts from a certain category or from a certain tag?
    Thanks.

    That’s this link:

    I have made some progress but I have two problems yet.
    What I have made:
    a) copied the template file category.php as page-mytemp.php
    b) create a page mytemp.php
    c) edited page-mytemp.php template inserting your code, after changing posts_per_page from -1 to 5
    Now, when I ask for mytemp page, I see the list of the last 5 posts in my categories, but:
    1) the whole post contents are displayes, even if I have inserted the <!–more–> tag
    2) the [next posts] and [previous posts] links at the bottom are not displayed.
    Notice that if I ask for a category, the teaser is respected and the navigation links are displayed.
    Maybe there there any other parameters to define $args?
    Thanks for your patience.

    Update: added the following lines to template but without success. 🙁

    global $more;
    // set $more to 0 in order to only get the first part of the post
    $more = 0;

    1. Put that global $more; $more=0; right before your the_content();

    global $more;
    $more = 0;
    the_content('Read more...');

    2. I’ve never quite gotten pagination to work on a Page.

    1. Solved. Thank you.
    2. Do you mean it’s impossible? I do not understand why category.php template displays navigation links and page-mytemp.php, which is identical apart the lines before
    <?php while (have_posts()) : the_post(); ?>
    doesn’t.
    I have seen that function get_next_posts_link in link-template.php is called, but my limited knowledge does not allow me to understand the rest.

    Ok, I understand that if the [previous posts] link recalls the same page the query is re-executed …
    I’m asking if the “Page” approach is suitable. Is any hack of category template possible?

    Thread Starter antr

    (@antr)

    Maybe a suggestion.
    If I modify index.php for Home Page, adding
    <?php query_posts($query_string . '&cat=-3,-8'); ?>
    line as made in
    http://codex.wordpress.org/The_Loop#Exclude_Posts_From_Some_Category,
    navigation buttons are displayed.
    So, is there any method to create a page which acts as Home Page?
    In other words, can I have many different home pages?

    The page approach is fine but for the ‘pagination’ 😉 Though I’ve never tried a plugin like wp-pagenavi…

    Ok, I have verified that the “hack” works even if I add the above code line in category-mycategory.php. So I will submit another topic to see if category posts can be recalled from pages menu.

    Edit: I solved pointing my page to category/mycategory/ using Page Links To plugin. It would be perfect if I could use relative paths instead of absolute path, but the workaround is acceptable for my needings.
