我认为您的查询有问题

$query = mysql_query("UPDATE members SET imagelocation='$location' WHERE username='$username'");

因为您没有在脚本中的任何位置定义 $username 变量，因此您的查询正在检查

UPDATE members SET imagelocation='$location' WHERE username ='';

if ($_POST['submit'])应该是if ($_POST['Submit'])因为您的提交按钮名称以大写S开头而不是小 s

代替

if ($_POST['submit'])

和

if (isset($_POST['submit']))
