 $username=$_SESSION['username'];
 $checkinfo = mysql_query("SELECT * FROM profile WHERE username=".'"$username"');
//$result=mysql_fetch_array($checkinfo);
while($result = mysql_fetch_array($checkinfo,MYSQL_ASSOC)){

我希望已经存储在数据库中的值应该在会话中的特定用户的文本框中获取，而不是在文本框中获取值。

Answer 1

$checkinfo = mysql_query("SELECT * FROM profile WHERE username=".'"$username"');

应该是

$checkinfo = mysql_query("SELECT * FROM profile WHERE username='$username'");

您的UPDATE语法也不正确

Answer 2

SQL UPDATE语句：

 UPDATE table_name
SET column1=value, column2=value2,...
WHERE some_column=some_value

PHP中的数据库中没有从文本框中获取的值
