它显示用户名很好，我在数据库中有正确的表和列，但是当你点击上传它什么也没做？

您可以通过以用户名登录来自行查看：test password：test url：learning.iamdanbarrett.com

Answer 1

我认为您的查询存在问题

$query = mysql_query("UPDATE members SET imagelocation='$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 ='';

Answer 2

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

Answer 3

替换

if ($_POST['submit'])

与

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

努力将其上传到我的数据库中
