Put the post_img_number function in functions. php.

Function post_img_number () {global $ post, $ posts; ob_start (); ob_end_clean (); // use do_encode code ($ post-> post_content) to process the photo album statistics $ output = preg_match_all ('// I', do_coding code ($ post-> post_content), $ matches ); $ cnt = count ($ matches [1]); return $ cnt ;}
