在 Wordpress 中以编程方式更改用户头像 [英] Change User Avatar Programmatically in Wordpress

问题描述

是否可以通过编程方式更改 WordPress 中的用户头像?我这么问是因为我现在在 WordPress 多站点中显示用户头像时遇到问题:头像未显示.

Is it possible to change the user avatar in WordPress programmatically? I'm asking because I'm facing a problem right now in displaying the user avatar in WordPress multisite: the Avatar is not displaying.

推荐答案

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，并从托管在远程 URL 的头像开始.

I had to do three things to be able to programmatically insert user avatars into my WordPress starting with an avatar that is hosted at a remote URL.

1. 安装 WP 用户头像插件.
2. 借用 WooCommerce 的上传功能.见下文.
3. 改编来自类似支持帖子
的一些代码

1. Install the WP User Avatar plugin.
2. Borrow an upload function from WooCommerce. See below.
3. Adapt some code from a similar support post

假设您有一个用户，其头像是 $avatar_url = 'http://cdn.sstatic.net/stackoverflow/img/[e-mail]?v=73d79a89bded&a';

Suppose you have a user whose avatar is $avatar_url = 'http://cdn.sstatic.net/stackoverflow/img/[e-mail]?v=73d79a89bded&a';

我使用 WooCommerce 的 class-wc-api-products.php 中的 upload_product_image() 将头像放入我的本地服务器.

I use the upload_product_image() from WooCommerce's class-wc-api-products.php to get the avatar into my local server.

然后，使用此支持帖子中的一些代码，创建附件.然后将附件与用户关联起来.

Then, using some of the code from this support post, create an attachment. Then associate the attachment with the user.

这仅适用于 WP User Avatar 插件.

This works only with the WP User Avatar plugin.

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);
    }

来自 WooCommerce 的 class-wc-api-products.php

/**
 * WooCommerce class-wc-api-products.php
 * See https://github.com/justinshreve/woocommerce/blob/master/includes/api/class-wc-api-products.php
 * Upload image from URL
 *
 * @since 2.2
 * @param string $image_url
 * @return int|WP_Error attachment id
 */
function upload_product_image($image_url) {
    $file_name = basename(current(explode('?', $image_url)));
    $wp_filetype = wp_check_filetype($file_name, null);
    $parsed_url = @parse_url($image_url);

    // Check parsed URL
    if(!$parsed_url || !is_array($parsed_url)) {
        throw new WC_API_Exception('woocommerce_api_invalid_product_image', sprintf(__('Invalid URL %s', 'woocommerce'), $image_url), 400);
    }

    // Ensure url is valid
    $image_url = str_replace(' ', '%20', $image_url);

    // Get the file
    $response = wp_safe_remote_get($image_url, array(
        'timeout' => 10
    ));

    if(is_wp_error($response) || 200 !== wp_remote_retrieve_response_code($response)) {
        throw new WC_API_Exception('woocommerce_api_invalid_remote_product_image', sprintf(__('Error getting remote image %s', 'woocommerce'), $image_url), 400);
    }

    // Ensure we have a file name and type
    if(!$wp_filetype['type']) {
        $headers = wp_remote_retrieve_headers($response);
        if(isset($headers['content-disposition']) && strstr($headers['content-disposition'], 'filename=')) {
            $disposition = end(explode('filename=', $headers['content-disposition']));
            $disposition = sanitize_file_name($disposition);
            $file_name = $disposition;
        }
        elseif(isset($headers['content-type']) && strstr($headers['content-type'], 'image/')) {
            $file_name = 'image.' . str_replace('image/', '', $headers['content-type']);
        }
        unset($headers);
    }

    // Upload the file
    $upload = wp_upload_bits($file_name, '', wp_remote_retrieve_body($response));

    if($upload['error']) {
        throw new WC_API_Exception('woocommerce_api_product_image_upload_error', $upload['error'], 400);
    }

    // Get filesize
    $filesize = filesize($upload['file']);

    if(0 == $filesize) {
        @unlink($upload['file']);
        unset($upload);
        throw new WC_API_Exception('woocommerce_api_product_image_upload_file_error', __('Zero size file downloaded', 'woocommerce'), 400);
    }

    unset($response);

    return $upload;
}
