WordPress: How to filter posts by category using $wp_query?
Solution 1
You have to use
category_name
(string - use category slug) orcat
(int - use category id), to get post by category inWP_Query::query()
.
Here is an example:
$category_name = 'apples'; //replace it with your category slug
$temp = $wp_query;
$wp_query = null;
$wp_query = new WP_Query();
$wp_query->query('showposts=1' . '&paged=' . $paged . '&category_name=' . $category_name);
//...
//...
Hope this helps!
Solution 2
Delete your first php block and replace it with this
<?php
$args = array (
'showposts' => '1',
'category_name' => 'apples',
'paged' => $paged
);
$the_query = new WP_Query( $args );
if ( have_posts() ) : while ( $the_query->have_posts() ) : $the_query->the_post();
?>

I built a custom theme on WordPress with a static front page and no page set in Settings > Reading Settings > Front page displays as a posts page. I'd like to display posts, however, based on their categories throughout the site on different static pages. Therefore, I will never declare a posts index page through the console. And so I use the $wp_query function.
How can I add a filter to this script that only displays posts in the category "apples" (for example)? Right now, this script shows all posts regardless of category.
<?php $temp = $wp_query; $wp_query = null; $wp_query = new WP_Query(); $wp_query->query('showposts=1' . '&paged='.$paged); while ($wp_query->have_posts()) : $wp_query->the_post(); ?> <h2><a href="<?php the_permalink(); ?>" title="Read"><?php the_title(); ?></a></h2> <?php the_excerpt(); ?> <?php the_date(); ?> <?php endwhile; ?> <?php if ($paged > 1) { ?> <p><?php previous_posts_link('Previous page'); ?> <?php next_posts_link('Next page'); ?></p> <?php } else { ?> <p><?php next_posts_link('Next page'); ?></p> <?php } ?> <?php wp_reset_postdata(); ?>
