I'm very new to word press having only installed it on the weekend, I'm fine with HTML & CSS but PHP & Wordpress is alien to me.

I'm trying to display a post from a specific category that changes every day, i've searched everywhere and found the below code whihc works to a point.

I just cant seem to get it to choose from a category number?

Any help or explanation would be much appreciated.

    <?php
if ( false === ( $totd_trans_post_id = get_transient( 'totd_trans_post_id' ) ) ) {
     $args = array('numberposts' => 1, 'orderby' => 'rand');
     $totd = get_posts($args);
     $midnight = strtotime('midnight +1 day');
     $timenow = time();
     $timetillmidnight = $midnight - $timenow;
     echo $midnight;
     echo ",".$timenow;
     set_transient('totd_trans_post_id', $totd[0]->ID, $timetillmidnight);
} else {
    $args = array('post__in' => array($totd_trans_post_id));
    $totd = get_posts($args);
}

foreach( $totd as $post ) : setup_postdata($post); ?>
    <div>
        <a href="<?php the_permalink(); ?>"><?php the_title(); ?></a>
        <?php the_content(); ?>
    </div>
<?php endforeach; ?>

EDIT Thanks for the suggestions but nothing seems to be working with my existing code, it still continues to pick a completey random post from all categories.

You can change your get_posts $args

Example:

$args = array(
    'orderby' => 'rand',
    'category_name' => 'your_category',
    'showposts' => 1
);

  • thanks for the reply giolliano sulit but still not working, would the first line be overiding the categorty selection? if ( false === ( $totd_trans_post_id = get_transient( 'totd_trans_post_id' ) ) ) { – BuzzinBilly Aug 1 '17 at 18:29
  • Well you can try to run just the query in the else{ and see if that works. – giolliano sulit Aug 1 '17 at 23:02

Just use WP_Query() to generate your custom query, category parameters.

<?php
$category_query_args = array(
    'orderby' => 'rand',
    'category_name' => 'your_category'
);

$category_query = new WP_Query( $category_query_args );
?>

Note: you could also pass the category slug to the query, via category_name, instead of cat.

And just forward your loop.

<?php
if ( $category_query->have_posts() ) : while $category_query->have_posts() : $category_query->the_post();
// Loop output goes here
endwhile; endif;
?>

Hope This will help you.
