在WordPress中的MySQL查詢中獲取作者的頭像

Question

我使用WordPress網站中的以下代碼從wp_cp表中提取作者ID，點數，並且完美地工作。我現在正在嘗試的是在用戶ID旁邊獲取用戶頭像。我如何在代碼中獲得用戶頭像？

<?php 

    global $wpdb; 
    /* wpdb class should not be called directly.global $wpdb variable is an instantiation of the class already set up to talk to the WordPress database */ 

    $result = $wpdb->get_results("SELECT uid,sum(points) as pt FROM wp_cp where timestamp between '2015-12-12' and '2015-12-31' group by uid "); /*mulitple row results can be pulled from the database with get_results function and outputs an object which is stored in $result */ 

    //echo "<pre>"; print_r($result); echo "</pre>"; 
    /* If you require you may print and view the contents of $result object */ 

    echo "uid"." "."pt"."<br><br>"; 



    foreach($result as $row) 
    { 

    echo $row->uid." ".$row->pt."<br>"; 

    } 
    /* Print the contents of $result looping through each row returned in the result */ 

?> 

Answer 1

添加以下代碼來獲取的foreach內用戶頭像循環。

echo get_avatar($row->uid); 

由於您要求的尺寸，您可以添加一個參數到這個功能。

echo get_avatar($row->uid, 64); // So the avatar size will be 64px X 64 px.

如果使用uid字段（匹配用戶在wp_users ID），它傳遞到get_avatar功能：
