I'm using the following query to fetch posts in a category (10). I would like to change this code to use the category slug or name instead of the id number as this often changes when I move sites about.??

<?php $custom_query = new WP_Query(array ('cat' => 10, 'showposts' => 1));
query_posts($custom_query);
while($custom_query->have_posts()) : $custom_query->the_post();?>

I've tried changing ('cat' => 'books'... ('cat_name => 'books'... & also ('cat_slug => "books"... but nothing seems to work.

Many thanks

Following the first suggestion I've now got this working:

<?php 
$query = new WP_Query('category_name=books');
while($query->have_posts()) : $query->the_post();?>

But now need help combining the "posts_per_page" bit of the query??

Lets start by removing the query_posts() from your code since you already have it's better brother new WP_Query.

Then what you will need is to use the category_name param on your WP_Query.

You should always search on the WP_Query page before you ask here, you can find more referencers there.


Here is how @speedypancake resolved the issue:

<?php 
$the_query = new WP_Query(
    array( 
        'posts_per_page' => '10', 
        'category_name' => 'books'
    )
);
while( $the_query->have_posts() ): $the_query->the_post();
    // Do what you want
endwhile;

  • You mean like this?? <?php $custom_query = new WP_Query(array ('cat_name' => 'books', 'showposts' => 15)); while($custom_query->have_posts()) : $custom_query->the_post();?> Oct 26 '14 at 13:13

Following Bordoni's lead, and with a bit of trial and error, finally got it working

<?php 
$the_query = new WP_Query( array ( 
'posts_per_page' => '10', 
'category_name' => 'books'
 ) );
while($the_query->have_posts()) : $the_query->the_post();
?>

@Bordoni - Thanks for the hint!
