Edge case: array expected in sempress_pre_get_avatar_data

I was trying to solve an unrelated problem but couldn’t find any logs for it due to the high volume of PHP warnings that array_merge expects the first parameter to be an array.

I tracked down the function where the error was taking place and this is my fix.

If it turns out that args['class'] exists but isn’t an array, make it into an array.

function sempress_pre_get_avatar_data( $args, $id_or_email ) { if ( ! isset( $args['class'] ) ) { $args['class'] = array(); } if( ! is_array($args['class'])){ $args['class'] = array($args['class']); } // Adds a class for microformats v2 $args['class'] = array_unique( array_merge( $args['class'], array( 'u-photo' ) ) ); $args['extra_attr'] = 'itemprop="image"'; return $args; }
