Sort posts according to a numeric value entered with ACF
I've tried a little bit of everything, but I still can't find the right solution.
I need to sort my posts according to a numeric value that is entered in each post. I'm using the following PHP code, but it's not working:
$args['meta_query'] = array(
array(
'key' = 'key',
'type' = 'numeric',
)
);
I also tried this code:
$args['meta_key'] = 'costo_attrazioni_ridotti_18_25';
Then of course I have these other values in the args as well:
$paged = ( get_query_var('paged') ) ? get_query_var('paged') : 1;
$args=array(
'post_type' = 'post',
'post_status' = 'publish',
'posts_per_page' = 10,
'meta_key' = 'costo_attrazioni_ridotti_18_25',
'order' = 'ASC',
'orderby' = 'meta_value_num',
'paged' = $paged,
);
$the_query = new WP_Query( $args );
if ($the_query-have_posts()):
while ($the_query - have_posts()) : $the_query - the_post();?
...
endwhile;
endif; unset($the_query); wp_reset_query();
How can I solve it? Thank you.
