我必须做三件事才能以编程方式将用户头像插入到我的 WordPress 中,从托管在远程 URL 的头像开始。
- 安装WP User Avatar 插件。
- 从 WooCommerce 借用上传功能。见下文。
- 改编一些类似support post的代码
假设你有一个头像是$avatar_url = 'http://cdn.sstatic.net/stackoverflow/img/apple-touch-icon@2.png?v=73d79a89bded&a';的用户
我使用 WooCommerce 的 class-wc-api-products.php 中的 upload_product_image() 将头像导入我的本地服务器。
然后,使用此support post 中的一些代码,创建一个附件。
然后将附件与用户关联。
这仅适用于 WP User Avatar 插件。
function se13911452_set_avatar_url($avatar_url, $user_id) {
global $wpdb;
$file = upload_product_image($avatar_url);
$wp_filetype = wp_check_filetype($file['file']);
$attachment = array(
'guid' => $file['url'],
'post_mime_type' => $wp_filetype['type'],
'post_title' => preg_replace('/\.[^.]+$/', '', basename($file['file'])),
'post_content' => '',
'post_status' => 'inherit'
);
$attach_id = wp_insert_attachment($attachment, $file['file']);
$attach_data = wp_generate_attachment_metadata($attach_id, $file['file']);
wp_update_attachment_metadata($attach_id, $attach_data);
update_user_meta($user_id, $wpdb->get_blog_prefix() . 'user_avatar', $attach_id);
}
