php - Exclude / Not equal multiple values in wordpress query -


i have modified wordpress query.

i need exclude 3 values cannot figure out how it. have read lots of people passing more 1 value match not exclude. have tried several things across several hours.

$popularpost = new wp_query( array( 'posts_per_page' => '12',  'cat' => $cat_id, 'posts_type' => 'post', 'paged' => $paged,  'meta_key' => 'post_price',  'meta_value' =>'swap', 'free', 'wanted', 'meta_compare' => '!=',

any appreciated.

there issue here:

'meta_value' =>'swap', 'free', 'wanted',

in case meta_value set swap. free , wanted separate entries in array. writing code out reveals problem:

array(      'posts_per_page' => '12',      'cat' => $cat_id,     'posts_type' => 'post',     'paged' => $paged,      'meta_key' => 'post_price',      'meta_value' => 'swap',      'free',      'wanted',     'meta_compare' => '!=',     ... )

i think want:

'meta_value' => array('swap', 'free', 'wanted'),
