How can i get posts sorted out by meta_key from inner key array of post meta values, for more details please look at my code:
// Example output of each post_meta, key is views
array(
'all' => '334',
'new' = '28',
'old' => '280'
)
// wp_query with meta_query not working with above meta_key
$popular = new WP_Query( array(
'post_type' => 'songs',
'showposts' => '20',
'order' => 'DSC',
'meta_key' => 'views', // i want something like this views['all']
'orderby' => 'meta_value_num'
) );
WP_Querybecause the data is serialized in the database ( automagically ). The solution would be to split them into their own post meta key value pairs than an array.WP_Querywon't do this without a lot of help from filters but I'd sort in PHP if it were me. The complexity of the query you'd need is pretty high and I doubt the query would be efficient.view_new,view_oldandview_all. If you have existing data in the database. I will advice you to write code which (run once) go through each post and split the data into three individual meta.meta_query. It is a limit at the database level. The database can't reliably manage serialized data, which is a PHP construct, not a MySQL one. It is just bad, bad, bad data design to shove multiple pieces of different information into the same key. It is a bit like making trailmix out of your information and expecting to be able to easily un-trailmix later.
