    Hello everyone! I am using the code below to display the most recent post from a certain category on a specific page. How can I modify this to display a random post from multiple specific categories instead? Or is there some entirely different code I should use? 

    <?php
            // page id 224 will get category ID 7 posts
            if (is_page('224') ) {
            $cat = array(7);
            } else {
            $cat = '';
            }

            $showposts = 1; // -1 shows all posts
            $do_not_show_stickies = 1; // 0 to show stickies
            $args=array(
               'category__in' => $cat,
               'showposts' => $showposts,
               'caller_get_posts' => $do_not_show_stickies
               );
            $my_query = new WP_Query($args); 

            ?>

	<?php if( $my_query->have_posts() ) : ?>

		<?php while ($my_query->have_posts()) : $my_query->the_post(); ?>
			<?php
			//necessary to show the tags
			global $wp_query;
			$wp_query->in_the_loop = true;
			?>

  • Hi,

    Try change:

    $args=array(
               'category__in' => $cat,
               'showposts' => $showposts,
               'caller_get_posts' => $do_not_show_stickies
               );

    To:

    $args=array(
               'category__in' => array($cat1, $cat2), //your multiple categories
               'showposts' => $showposts,
               'caller_get_posts' => $do_not_show_stickies,
               'orderby' => 'rand'
               );

    Hmmm… so should the whole thing look like this then…

    <?php
            // page id 224 will get category ID 7 posts
            if (is_page('224') ) {
            $cat1 = array(7);
			$cat2 = array(8);
            } else {
            $cat = '';
            }

            $showposts = 1; // -1 shows all posts
            $do_not_show_stickies = 1; // 0 to show stickies
            $args=array(
			   'category__in' => array($cat1, $cat2), //your multiple categories
               'showposts' => $showposts,
               'caller_get_posts' => $do_not_show_stickies,
               'orderby' => 'rand'
               );
            $my_query = new WP_Query($args); 

            ?>

    I get an “not found” error when I do that. Not sure if I did that right.

    Or would be something like this…

    if (is_page('224') ) {
            $cat = array(7,8);
            } else {
            $cat = '';
            }

    Sorry, dont noticed you alredy have array in $cat.

    <?php
            // page id 224 will get category ID 7 posts
            if (is_page('224') ) {
            $cat = array(7,8); //will get posts for 7 and 8 categories
            } else {
            $cat = '';
            }

            $showposts = 1; // -1 shows all posts
            $do_not_show_stickies = 1; // 0 to show stickies
            $args=array(
			   'category__in' => $cat,
               'showposts' => $showposts,
               'caller_get_posts' => $do_not_show_stickies,
               'orderby' => 'rand'
               );
            $my_query = new WP_Query($args); 

            ?>
