WordPress默認的頭像是讀取gravatar.com上的圖片的,對於國內用戶來說會使網頁打開速度變慢。所以我決定刪除掉這塊功能。
修改get_avatar函數,在wp-includes/pluggable.php內。修改後的函數如下:
代碼如下:
<?php
if (!function_exists('get_avatar')) :
/**
* Retrieve the avatar for a user who provided a user ID or email address.
*
* @since 2.5
* @param int|string|object $id_or_email A user ID, email address, or comment object
* @param int $size Size of the avatar image
* @param string $default URL to a default image to use if no avatar is available
* @param string $alt Alternate text to use in image tag. Defaults to blank
* @return string tag for the user's avatar
*/
function get_avatar($id_or_email, $size = '96', $default = '', $alt = false) {
if (!get_option('show_avatars'))
return false;
if (false === $alt)
$safe_alt = '';
else
$safe_alt = esc_attr($alt);
if (!is_numeric($size))
$size = '96';
$default = includes_url('images/blank.gif');
$avatar = "";
return apply_filters('get_avatar', $avatar, $id_or_email, $size, $default, $alt);
}
endif;
即使用該函數,僅可能返回一個默認頭像(位於wp-includes/images/blank.gif內),再配合simple local avatars或Add Local Avatar插件,就實現了預期的效果。
