Question

是否可以通过编程方式更改WordPress中的用户头像？我问，因为我现在在WordPress多站点中显示用户头像时遇到问题：头像没有显示。

Answer 1

最有可能在某个地方调用get_avatar过滤器并执行某些操作。我建议您搜索get_avatar的插件和主题，并查看类似的内容：add_filter ('get_avatar', .....

否则，您可以使用以下代码编写自己的行为。

<?php // in a plugin file or in a theme functions.php
function SO13911452_override_avatar ($avatar_html, $id_or_email, $size, $default, $alt) {
    // check all values

    return $avatar_html
}
add_filter ('get_avatar', 'SO13911452_override_avatar', 10, 5);

Answer 2

我必须做三件事才能以编程方式将用户头像插入我的WordPress，从一个托管在远程URL的头像开始。

安装WP User Avatar插件。
借用WooCommerce的上传功能。见下文。
调整类似support post

假设您的用户的头像为public class QuestionsAdapter extends RecyclerView.Adapter<QuestionsAdapter.QuestionsViewHolder> { List<QuestionModel> Questions; public Context context; public QuestionsAdapter(Context context, List<QuestionModel> questions) { this.Questions = questions; this.context = context; } @Override public QuestionsViewHolder onCreateViewHolder(ViewGroup parent, int viewType) { View v = LayoutInflater.from(parent.getContext()).inflate(R.layout.questions_card_view, parent, false); return new QuestionsViewHolder(v); } @Override public void onBindViewHolder(QuestionsViewHolder holder, final int position) { holder.txtQuestionText.setText(Questions.get(position).QuestionText); } @Override public int getItemCount() { return Questions.size(); } @Override public void onAttachedToRecyclerView(RecyclerView recyclerView) { super.onAttachedToRecyclerView(recyclerView); } public class QuestionsViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener { public RadioButton rbLike; public RadioButton rbdisLike; public RadioButton rbnoComment; public TextView txtQuestionText; public QuestionsViewHolder(View itemView) { super(itemView); rbLike = (RadioButton) itemView.findViewById(R.id.like); rbdisLike = (RadioButton) itemView.findViewById(R.id.Dislike); txtQuestionText = (TextView) itemView.findViewById(R.id.txtCardQuestion); rbnoComment = (RadioButton) itemView.findViewById(R.id.NoComment); rbnoComment.setOnClickListener(this); rbdisLike.setOnClickListener(this); rbLike.setOnClickListener(this); } @Override public void onClick(View v) { switch (v.getId()) { case R.id.like: rbLike.setChecked(true); rbnoComment.setChecked(false); rbdisLike.setChecked(false); break; case R.id.Dislike: rbdisLike.setChecked(true); rbnoComment.setChecked(false); rbLike.setChecked(false); break; case R.id.NoComment: rbnoComment.setChecked(true); rbLike.setChecked(false); rbdisLike.setChecked(false); //do something break; default: } } }

我使用WooCommerce的$avatar_url = 'http://cdn.sstatic.net/stackoverflow/img/apple-touch-icon@2.png?v=73d79a89bded&a';中的upload_product_image()将头像带入我的本地服务器。

然后，使用此support post中的部分代码创建附件。然后将附件与用户关联。

这仅适用于WP用户头像插件。

class-wc-api-products.php

来自WooCommerce's class-wc-api-products.php

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);
    }

Answer 3

这将起作用：

add_filter('get_avatar_data', 'ht1_change_avatar', 100, 2);

function ht1_change_avatar($args, $id_or_email) {
    if($id_or_email == 1) {
        $args['url'] = 'https://uinames.com/api/photos/female/1.jpg';
    }

    if($id_or_email == 2) {
        $args['url'] = 'https://uinames.com/api/photos/male/19.jpg';
    }

    return $args;
} // end of function

如果您具有用户的头像目录位置元数据，则将其用于所有用户：

add_filter('get_avatar_data', 'ht1_change_avatar', 100, 2);

function ht1_change_avatar($args, $id_or_email) {
    $avatar_url = get_user_meta($id_or_email, 'avatar', true);

    $args['url'] = $avatar_url;

    return $args;
} // end of function

希望您明白这一点。
