posts_per_page no limit

Question

I want to return ALL posts with query_posts. I tried setting posts_per_page to a really high number, but query_posts freaks out and doesn't return any posts. What is the correct way to query posts without a limit?

$args = array(
    'post_type'      => 'post',
    'cat'            => '22,47,67',
    'orderby'        => 'name',
    'order'          => 'ASC',
    'hide_empty'     => 1,
    'depth'          => 1,
    'posts_per_page' => ?
    );

Answer 1

-1 is your answer! Look for posts_per_page here.

$args = array(
'post_type'      => 'post',
'cat'            => '22,47,67',
'orderby'        => 'name',
'order'          => 'ASC',
'hide_empty'     => 1,
'depth'          => 1,
'posts_per_page' => -1
);

Or alternatively you can pass WP_Query(which is what query_posts uses) the nopaging argument, which basically does the same thing..

$args = array(
    'nopaging' => true
    // Your other args, etc..
);

It will do exactly the same, but if you have to look back at it later and can't remember what you were doing, i personally feel it will be more clear to you what you were specifying inside the args array, though like i said, they'll both actually archieve the same.

Can't hurt to have more than one approach, and it's always nice to share what you know, suffice to say that's the reason for my answer, despite you already having a sufficient one.. ;)
