I have a form, which has an upload ($_FILES['watch_photo']
) field.
I have looked around and came to put this function together.
It basically takes all relevant information so it is re-usable in the future, it will return an array of the $pid, and URL of the file, when it is done.
The problem is that ACF has not provided much information how to add images to it’s fields using update_field()
http://www.advancedcustomfields.com/resources/functions/update_field/
function my_update_attachment($f,$pid,$t='',$c='') { wp_update_attachment_metadata( $pid, $f ); if( !empty( $_FILES[$f]['name'] )) { //New upload require_once( ABSPATH . 'wp-admin/includes/file.php' ); $override['action'] = 'editpost'; $file = wp_handle_upload( $_FILES[$f], $override ); if ( isset( $file['error'] )) { return new WP_Error( 'upload_error', $file['error'] ); } $file_type = wp_check_filetype($_FILES[$f]['name'], array( 'jpg|jpeg' => 'image/jpeg', 'gif' => 'image/gif', 'png' => 'image/png', )); if ($file_type['type']) { $name_parts = pathinfo( $file['file'] ); $name = $file['filename']; $type = $file['type']; $title = $t ? $t : $name; $content = $c; $attachment = array( 'post_title' => $title, 'post_type' => 'attachment', 'post_content' => $content, 'post_parent' => $pid, 'post_mime_type' => $type, 'guid' => $file['url'], ); foreach( get_intermediate_image_sizes() as $s ) { $sizes[$s] = array( 'width' => '', 'height' => '', 'crop' => true ); $sizes[$s]['width'] = get_option( "{$s}_size_w" ); // For default sizes set in options $sizes[$s]['height'] = get_option( "{$s}_size_h" ); // For default sizes set in options $sizes[$s]['crop'] = get_option( "{$s}_crop" ); // For default sizes set in options } $sizes = apply_filters( 'intermediate_image_sizes_advanced', $sizes ); foreach( $sizes as $size => $size_data ) { $resized = image_make_intermediate_size( $file['file'], $size_data['width'], $size_data['height'], $size_data['crop'] ); if ( $resized ) $metadata['sizes'][$size] = $resized; } $attach_id = wp_insert_attachment( $attachment, $file['file'] /*, $pid - for post_thumbnails*/); if ( !is_wp_error( $id )) { $attach_meta = wp_generate_attachment_metadata( $attach_id, $file['file'] ); wp_update_attachment_metadata( $attach_id, $attach_meta ); } return array( 'pid' =>$pid, 'url' =>$file['url'] ); // update_post_meta( $pid, 'a_image', $file['url'] ); } } }
and then I used the following code:
- to create a post and then
- upload then use
my_update_attachment
to process the image - and finally update the advanced custom field
The code:
$args= array( 'post_type' => 'watches', 'post_status' => 'publish' ); $watch = wp_insert_post($args); $att = my_update_attachment('watch_image',$watch); update_field('field_512e085a9372a',$att['url'],$watch);
What am I missing? any help would be greatly appreciated.

Answer
I had the same problem, you almost had it right, which helped me as well.
looked at ACF and the update_field
accepts attachment ID as oppose to the the, pid
or url
You can replace the return array:
return array( 'pid' =>$pid, 'url' =>$file['url'] );
With the following array:
return array( 'pid' =>$pid, 'url' =>$file['url'], 'file'=>$file, 'attach_id'=>$attach_id );
and then change
update_field('field_512e085a9372a',$att['url'],$watch);
with the following
update_field('field_512e085a9372a',$att['attach_id'],$watch);
