Question

Im trying to output or create json using wordpress posts data coupled with meta_key values.

This is the code I’m using, but its forming the JSON incorrectly.

$query = new WP_Query('cat=4&meta_key=meta_long');

echo "var json=". json_encode($query);

Any ideas of how to do this?

Try this:

$query = new WP_Query('cat=4&meta_key=meta_long');

echo "var json=". json_encode($query->get_posts());
