WordPress get all posts of a specific category

23 May, 2013

How to get all posts of a specific category or sub category in wordpress?Here I’m going to explain how to get all posts of a specific category or sub category.

You can execute wordpress query to get specific category details as follows.

$category_id = 10;// my category ID
	$args = array(
				   'cat' => $category_id,
				   'post_type' => 'post',
				   'posts_per_page' => 9, // number of posts to a page
				   'paged' => ( get_query_var('paged') ? get_query_var('paged') : 1), // pagination
				   );

$cat_query = new WP_Query($args);

$category_id = 10;// my category ID

$args = array(

'cat' => $category_id,

'post_type' => 'post',

'posts_per_page' => 9, // number of posts to a page

'paged' => ( get_query_var('paged') ? get_query_var('paged') : 1), // pagination

);

$cat_query = new WP_Query($args);

This will return all posts of that category query.Now we can get all posts using while loop.

if( $cat_query->have_posts() ) : $count=0;
   while ( $cat_query->have_posts() ) : $cat_query->the_post();
 // ---------------------- display post details here --------
  endwhile;
endif;

// reset query
wp_reset_query();

if( $cat_query->have_posts() ) : $count=0;

while ( $cat_query->have_posts() ) : $cat_query->the_post();

// ---------------------- display post details here --------

endwhile;

endif;

// reset query

wp_reset_query();

Her is the full code to get all details with thumbnails of each posts.

<?php
	$args = array(
				   'cat' => $category_id,
				   'post_type' => 'post',
				   'posts_per_page' => 9,
				   'paged' => ( get_query_var('paged') ? get_query_var('paged') : 1),
				   );

$cat_query = new WP_Query($args); 

if( $cat_query->have_posts() ) : $count=0;?>
	<section id="related_posts">
		<div class="post-listing">
			<?php while ( $cat_query->have_posts() ) : $cat_query->the_post()?>
			<div class="related-item">
				<?php if ( function_exists("has_post_thumbnail") && has_post_thumbnail() ) : ?>			
				<div class="post-thumbnail">
					<a href="<?php the_permalink(); ?>" title="<?php printf( __( 'Permalink to %s', 'tie' ), the_title_attribute( 'echo=0' ) ); ?>" rel="bookmark">
						<?php tie_thumb('', 300 ,160); ?>
						<?php tie_get_score(  ); ?>
					</a>
				</div><!-- post-thumbnail /-->
				<?php endif; ?>			
				<h3><a href="<?php the_permalink(); ?>" title="<?php printf( __( 'Permalink to %s', 'tie' ), the_title_attribute( 'echo=0' ) ); ?>" rel="bookmark"><?php $tit = the_title('','',FALSE); echo substr($tit, 0, 50);if (strlen($tit) > 50) echo " ...";?></a></h3>
				<p class="post-meta"><?php tie_get_time() ?></p>
			</div>
			<?php endwhile;?>
			<div class="clear"></div>
		</div>
	</section>
	<?php	endif;
	
	wp_reset_query();
?>

<?php

$args = array(

'cat' => $category_id,

'post_type' => 'post',

'posts_per_page' => 9,

'paged' => ( get_query_var('paged') ? get_query_var('paged') : 1),

);

$cat_query = new WP_Query($args);

if( $cat_query->have_posts() ) : $count=0;?>

<?php while ( $cat_query->have_posts() ) : $cat_query->the_post()?>

<?php if ( function_exists("has_post_thumbnail") && has_post_thumbnail() ) : ?>

<a href="<?php the_permalink(); ?>" title="<?php printf( __( 'Permalink to %s', 'tie' ), the_title_attribute( 'echo=0' ) ); ?>" rel="bookmark">

<?php tie_thumb('', 300 ,160); ?>

<?php tie_get_score( ); ?>

</a>

</div>

<?php endif; ?>

<h3><a href="<?php the_permalink(); ?>" title="<?php printf( __( 'Permalink to %s', 'tie' ), the_title_attribute( 'echo=0' ) ); ?>" rel="bookmark"><?php $tit = the_title('','',FALSE); echo substr($tit, 0, 50);if (strlen($tit) > 50) echo " ...";?></a></h3>
