问题
i'm trying to order multiples post types in a page my solution below is working but the posts are not showing by type after type exactly
<?php $args = array_merge( $wp_query->query,
array( 'post_type' =>array( 'editorial','video','portfolio' ),'posts_per_page=-1','orderby'=>'post_type') );
}
query_posts( $args );
$postType='';
if (have_posts()) : while (have_posts()) : the_post();
$PT = get_post_type( $post->ID );
if($postType != $PT){
$postType = $PT;
echo '<p class="clearfix"><h1>All posts of type : '.$postType.'</h1></p>';
}
?>
<?php
if($postType == 'editorial'){ ?>
<?php echo $postType; ?>
<?php }elseif($postType == 'video'){ ?>
<?php echo $postType; ?>
<?php }elseif($postType == 'portfolio'){
<?php echo $postType; ?>
}
?>
and it output like that:
All posts of type : editorial
editorial
editorial
editorial
All posts of type : video
video
video
All posts of type : editorial //problem
editorial
All posts of type : portfolio
portfolio
portfolio
portfolio
portfolio
thank you in advance

According to the Codex, post_type
isn't one of the allowed values for the orderby
parameter.
One way around your problem would be to use the posts_orderby filter, something like this:
function order_posts_by_type($original_orderby_statement) {
global $wpdb;
return $wpdb->posts .".post_type ASC";
}
add_filter('posts_orderby', 'order_posts_by_type');
$custom_query = new WP_Query( array(
'post_type' =>array( 'editorial','video','portfolio' ),
'posts_per_page' => '-1',
'orderby'=>'post_type',
'order' => 'ASC'
) );
remove_filter('posts_orderby', 'order_posts_by_type');
FWIW, I'd suggest changing 'posts_per_page=-1'
to 'posts_per_page' => -1
to be consistent with your other arguments.
