Title: Store image caption Last modified: November 12, 2020 --- # Store image caption * Resolved [justmigrating](https://wordpress.org/support/users/justmigrating/) * (@justmigrating) * [5 years, 6 months ago](https://wordpress.org/support/topic/store-image-caption/) * Hi Nickolas- * I have been using code you provided to another user a couple years ago ([https://wordpress.org/support/topic/how-to-provide-post_title-post_content-post_excerpt/](https://wordpress.org/support/topic/how-to-provide-post_title-post_content-post_excerpt/)), and recently, the code stopped adding the caption to the uploaded image post. I have only one field with my upload form (Caption). In the plugin settings, I have specified to add images to the Media Library and to show Custom Fields in Media Library. I checked the WP database and the caption is stored in the postmeta table meta_key => _wp_attachment_metadata in a serialized array; however, the caption had been also added to the post table as post_title. This is no longer happening. The code I’m using is below. * Jennifer * ` if ( isset($GLOBALS["WFU_GLOBALS"]["WFU_DEBUG"]) ) $GLOBALS["WFU_GLOBALS"][" WFU_DEBUG"][3] = "ON"; if (!function_exists('wfu_debug_wfu_process_media_insert_function_handler')){ function wfu_debug_wfu_process_media_insert_function_handler($res, $file_path, $userdata_fields, $page_id) { $wp_upload_dir = wp_upload_dir(); $filetype = wp_check_filetype( wfu_basename( $file_path ), null ); $caption = ( isset($userdata_fields[0]) ? $userdata_fields[0]["value"] : "" ); $attachment = array( 'guid' => $wp_upload_dir[' url'] . '/' . wfu_basename( $file_path ), 'post_mime_type' => $filetype['type'],' post_title' => $caption, 'post_excerpt' => $caption, 'post_status' => 'inherit'); $attach_id = wp_insert_attachment( $attachment, $file_path, $page_id ); require_once( ABSPATH . 'wp-admin/includes/image.php'); $attach_data = wp_generate_attachment_metadata( $attach_id, $file_path ); $attach_data["WFU User Data"]["Created"] = $created; $update_attach = wp_update_attachment_metadata( $attach_id, $attach_data ); $ filedata = wfu_get_filedata($file_path, true); if ( $filedata != null ) { $filedata[" media"] = array( "type" => "data", "attach_id" => $attach_id ); wfu_save_filedata_from_id( $filedata["general"]["idlog"], $filedata); } $res["result"] = 'R'; $res["output"] = $attach_id; return $res; } add_filter('wfu_debug-wfu_process_media_insert',' wfu_debug_wfu_process_media_insert_function_handler', 10, 4); $GLOBALS['wfu_debug- wfu_process_media_insert'] = "1"; } Viewing 4 replies - 1 through 4 (of 4 total) * Plugin Author [nickboss](https://wordpress.org/support/users/nickboss/) * (@nickboss) * [5 years, 6 months ago](https://wordpress.org/support/topic/store-image-caption/#post-13671960) * Hi, this is strange, I see that post_title property is set while creating the attachment. * Is there any other plugin changing Media Items properties? * Regards * Nickolas * Thread Starter [justmigrating](https://wordpress.org/support/users/justmigrating/) * (@justmigrating) * [5 years, 6 months ago](https://wordpress.org/support/topic/store-image-caption/#post-13773949) * Nickolas – * No other plugins are installed that I think could be interfering with the code you provided to store the Caption upon image upload. When I look in the WordPress postmeta table, I can see the Caption there in a serialized array in the _wp_attachment_metadata key, but I can’t figure out how to retrieve the value. The value of the key is below, Caption is at the end of the serialized array. I have tried the following code to retrieve the value of the Caption, but it does not return anything. Any advice? * $my_data = wp_get_attachment_metadata( get_post_thumbnail_id( $postid ) ); $my_data = $my_data[‘WFU User Data’][‘Caption’]; echo $my_data; * a:6:{s:5:”width”;i:1200;s:6:”height”;i:1200;s:4:”file”;s:27:”2020/12/EnterpriseTheme. jpg”;s:5:”sizes”;a:3:{s:6:”medium”;a:4:{s:4:”file”;s:27:”EnterpriseTheme-400× 400.jpg”;s:5:”width”;i:400;s:6:”height”;i:400;s:9:”mime-type”;s:10:”image/jpeg”;} s:9:”thumbnail”;a:4:{s:4:”file”;s:27:”EnterpriseTheme-150×150.jpg”;s:5:”width”; i:150;s:6:”height”;i:150;s:9:”mime-type”;s:10:”image/jpeg”;}s:12:”medium_large”; a:4:{s:4:”file”;s:27:”EnterpriseTheme-768×768.jpg”;s:5:”width”;i:768;s:6:”height”; i:768;s:9:”mime-type”;s:10:”image/jpeg”;}}s:10:”image_meta”;a:12:{s:8:”aperture”; s:1:”0″;s:6:”credit”;s:0:””;s:6:”camera”;s:0:””;s:7:”caption”;s:0:””;s:17:”created_timestamp”; s:1:”0″;s:9:”copyright”;s:0:””;s:12:”focal_length”;s:1:”0″;s:3:”iso”;s:1:”0″; s:13:”shutter_speed”;s:1:”0″;s:5:”title”;s:0:””;s:11:”orientation”;s:1:”0″;s: 8:”keywords”;a:0:{}}s:13:”WFU User Data”;a:1:{s:7:”Caption”;s:26:”Enterprise WordPress Theme”;}} * Thread Starter [justmigrating](https://wordpress.org/support/users/justmigrating/) * (@justmigrating) * [5 years, 6 months ago](https://wordpress.org/support/topic/store-image-caption/#post-13774065) * Nickolas – turns out I still couldn’t get your code to work anymore, but I got what I needed with this code (in case anyone else sees this post). * $the_query = new WP_Query( array( ‘author’ => $user_id, ‘post_status’ => ‘inherit’,‘ post_type’ => ‘attachment’ ) )); if ( $the_query->have_posts() ) { while ( $the_query- >have_posts() ) { $the_query->the_post(); $imagelink = get_the_guid(); $postid = get_the_ID(); $metadata = wp_get_attachment_metadata($postid); $caption = $ metadata[‘WFU User Data’][‘Caption’]; } } wp_reset_postdata(); * Plugin Author [nickboss](https://wordpress.org/support/users/nickboss/) * (@nickboss) * [5 years, 6 months ago](https://wordpress.org/support/topic/store-image-caption/#post-13777289) * ok thanks * Regards * Nickolas Viewing 4 replies - 1 through 4 (of 4 total) The topic ‘Store image caption’ is closed to new replies. * ![](https://ps.w.org/wp-file-upload/assets/icon-256x256.png?rev=3252590) * [Iptanus File Upload](https://wordpress.org/plugins/wp-file-upload/) * [Frequently Asked Questions](https://wordpress.org/plugins/wp-file-upload/#faq) * [Support Threads](https://wordpress.org/support/plugin/wp-file-upload/) * [Active Topics](https://wordpress.org/support/plugin/wp-file-upload/active/) * [Unresolved Topics](https://wordpress.org/support/plugin/wp-file-upload/unresolved/) * [Reviews](https://wordpress.org/support/plugin/wp-file-upload/reviews/) ## Tags * [caption](https://wordpress.org/support/topic-tag/caption/) * 4 replies * 2 participants * Last reply from: [nickboss](https://wordpress.org/support/users/nickboss/) * Last activity: [5 years, 6 months ago](https://wordpress.org/support/topic/store-image-caption/#post-13777289) * Status: resolved
