description: 对于一些专业的摄影博客,在分享图片的时候,我们也许希望在显示图片的同时,能够在图片的旁边同时显示该图片的EXIF信息,这样对于专业的摄影人员可能会有所帮助,方便交流.我们在操作系统中或者专门的看图软件中能够很方便的看到EXIF信息,对于WordPress其实也是很容易就可以实现的.方法不外乎插件和代码:插件我们可以使用Display Exif这款插件,安装启用后就可以,不需要任何复杂的程序,连CSS也自带了.代码 // grab exif data from wp attachment function grab_exif_data_from_wp($post_ID, $debug = FALSE) { global $id, $post; if ( !isset($post_ID) || '' == $post_ID ) return FALSE; $meta = wp_get_attachment_metadata($post_ID, FALSE); $return = ''; if ( $meta['image_meta']['created_timestamp'] ) $return .= date( "d-M-Y H:i:s", $meta['image_meta']['created_timestamp'] ); if ( $meta['image_meta']['copyright'] ) $return .= $meta['image_meta']['copyright']; if ( $meta['image_meta']['credit'] ) $return .= $meta['image_meta']['credit']; if ( $meta['image_meta']['title'] ) $return .= $meta['image_meta']['title']; if ( $meta['image_meta']['caption'] ) $return .= $meta['image_meta']['caption']; if ( $meta['image_meta']['camera'] ) $return .= $meta['image_meta']['camera']; if ( $meta['image_meta']['focal_length'] ) $return .= __( '· Brennweite:', FB_GREYFOTO_TEXTDOMAIN ) . ' ' . $meta['image_meta']['focal_length'] . __( 'mm', FB_GREYFOTO_TEXTDOMAIN ); if ( $meta['image_meta']['aperture'] ) $return .= $meta['image_meta']['aperture']; if ( $meta['image_meta']['iso'] ) $return .= $meta['image_meta']['iso']; if ( $meta['image_meta']['shutter_speed'] ) $return .= number_format($meta['image_meta']['shutter_speed'], 2) . ' ' . __( 'seconds', FB_GREYFOTO_TEXTDOMAIN ); if ($debug) { ob_start(); var_dump($meta); $return = ob_get_clean(); } return $return; } function fb_simple_exif($post_ID, $debug) { $echo = grab_exif_data_from_wp($post_ID, $debug); if ( $echo && '' != $echo ) echo $echo; }
