/* | |
Pass meta_query as URL-encoded JSON | |
To borrow the example on http://codex.wordpress.org/Class_Reference/WP_Query | |
$args = array( | |
'meta_query' => array( | |
array( | |
'key' => 'age', | |
'value' => array(3, 4), | |
'compare' => 'IN', | |
) | |
) | |
); | |
Here's how that would look as a URL query param: | |
/?json=example/get_posts_by_meta_query&meta_query=%5B%7B%22key%22%3A%22age%22%2C%22value%22%3A%5B3%2C4%5D%2C%22compare%22%3A%22in%22%7D%5D | |
In JavaScript: | |
var meta_query = encodeURIComponent( | |
JSON.stringify([ | |
{ | |
key: 'age', | |
value: [3, 4], | |
compare: 'in' | |
} | |
]) | |
); | |
In PHP: | |
$meta_query = rawurlencode( | |
json_encode(array( | |
'key' => 'age', | |
'value' => array(3, 4), | |
'compare' => 'IN', | |
)) | |
); | |
*/ | |
$query = array( | |
'ignore_sticky_posts' => true, | |
'meta_query' => json_decode($_GET['meta_query'], true) | |
); | |
return array( | |
'posts' => $json_api->introspector->get_posts($query) | |
); | |
} | |
} | |
