我已经环顾四周了,把这个功能放在一起.

它基本上接收所有相关信息,以便将来可以重新使用,它将返回一个数组的$pid和文件的URL,当它完成.

问题是ACF没有提供很多信息,如何使用update_field()http://www.advancedcustomfields.com/resources/functions/update_field/将图像添加到它的字段

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'] );
    }
  }
}

然后我使用以下代码：

>创建一个帖子然后
>上传然后使用my_update_attachment来处理图像
>并最终更新高级自定义字段

代码：

$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);

我失踪了什么任何帮助将不胜感激.
