要做到这一点，你可以采取很多行动，我认为最好的一次行动是wp 或template_redirect.

使用这些操作中的任何一个，代码如下所示，此代码进入functions.php

add_action(\'wp\', \'bt_update_user_homepage_meta\');
function bt_update_user_homepage_meta () {
    // get user id, if user is not logged in then it will be 0
    $user_id = get_current_user_id();

    // now we check if we are in front page or not and we update the user meta accordingly
    // if user is not logged in this code will try to update the meta for user 0,
    // because this user doesn\'t exist, nothing will happen
    if (is_front_page()) update_user_meta($user_id, \'pagehome\', \'1\');
    else update_user_meta($user_id, \'pagehome\', \'0\');
}
