如何在wordpress上使用update_field在ACF上传图像

我有一个表单,其中包含上传($_FILES['watch_photo'])字段。

我环顾四周,开始把这个功能放在一起。

它基本上会获取所有相关信息,以便将来可以重复使用,它会在完成后返回$ pid和文件的URL数组。

问题是ACF没有提供太多信息,如何使用update_field() http://www.advancedcustomfields.com/resources/functions/update_field/

将图像添加到其字段中
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'] );
    }
  }
}

然后我使用了以下代码:

  • 创建帖子然后
  • 上传然后使用my_update_attachment处理图片
  • 最后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);

我错过了什么?任何帮助将不胜感激。

我遇到了同样的问题,你几乎把它弄好了,这对我有帮助。

查看了ACF,update_field接受了附件ID,与pidurl

相对

您可以替换返回数组:

return array(
    'pid' =>$pid,
    'url' =>$file['url']
);

使用以下数组:

return array(
  'pid' =>$pid,
  'url' =>$file['url'],
  'file'=>$file,
  'attach_id'=>$attach_id
);

然后更改

update_field('field_512e085a9372a',$att['url'],$watch);

以下

update_field('field_512e085a9372a',$att['attach_id'],$watch);

应该是这条线
if ( !is_wp_error( $attach_id )) {
成为
body { background-color: gery; } .cards { margin: 0 auto; max-width: 1000px; display: grid; grid-template-columns: repeat(auto-fill, minmax(225px, 1fr)); grid-auto-rows: auto; gap: 20px; padding-top: 30px; } .card { background-color: #fff; line-height: 1.5; font-size: 1.1em; padding: 15px; background: #fafafa; } .card__image { width: 100% !important; height: 150px; object-fit: cover; display: block; }

检查此插件:

  1. 使用frontendUploader字段创建ACF表单(插件扩展名)
  2. 将您的ACF表单添加到帖子中,并使用后管理面板使用复选框在前面查看
