Get author ID of a post in wordpress
提问by Zackskeeter
Im creating a loop where it pulls info about a users activity. the code is on the author page and what i want to to is get the current author ID, so based on what author page the user is on it will fetch the ID of that author.
我创建了一个循环，在其中提取有关用户活动的信息。代码在作者页面上，我想要的是获取当前作者 ID，因此根据用户所在的作者页面，它将获取该作者的 ID。
See below, i would want AUTHOR-ID to be the ID of the current author.
见下文，我希望 AUTHOR-ID 是当前作者的 ID。
<script type="text/javascript">
var pieData = [
<?php
$user_id = AUTHOR-ID;
/* Get all categories */
$rand = array('0', '1', '2', '3', '4', '5', '6', '7', '8', '9', 'a', 'b', 'c', 'd', 'e', 'f');
$categories = get_terms( 'category', 'orderby=count&hide_empty=0' );
/* Loop for each category to count the posts of the user */
foreach($categories as $category)
{
$color = '#'.$rand[rand(0,15)].$rand[rand(0,15)].$rand[rand(0,15)].$rand[rand(0,15)].$rand[rand(0,15)].$rand[rand(0,15)];
$cat_name = $category->name;
$cat_id = $category->term_id;
$post_count = count(get_posts("cat=$cat_id&post_author=$user_id"));
echo "
{
value: ".$post_count.",
color:'".$color."',
label: ".$user_id."
},";
}
?>
]
var myPie = new Chart(document.getElementById("piec").getContext("2d")).Pie(pieData);
</script>

On an author archive the following will get the author ID:
在作者档案中，以下内容将获得作者 ID：
$author_ID = get_query_var('author');
This will get you a lot more information:

$pageobj = get_queried_object();
