Multiple Tag Search WordPress -

wordpress 3.5.2. old construction

?tag=tag1+tag2 

doesn't work more. dunno why. have form check boxes. , tags sorts category. wanna search

tag1+tag2+tag3 

in specific category. how that? i'm tired solution :(

comma separate them:

/** posts of following tags */    $query = new wp_query( 'tag=bread,baking' );  /** posts of following tags */ $query = new wp_query( 'tag=bread+baking+recipe' );  /** or alternatively */ $query = new wp_query( array( 'tag_slug__in' => array( 'bread', 'baking' ) ) );
