刚创建了一个&change; changedetails.php'用户可以更改其详细信息的页面,例如密码'和'电子邮件'。它们都运作成功,但我试图允许用户更改他们的电子邮件,而不必更改他们的密码。
所以基本上,如果用户只想更改他们的电子邮件,它将在数据库中更新,而无需更改他们的密码。

谢谢!
更新2:
if ($newpassword != "") {
//check passwords
if ($oldpassword==$oldpassworddb)
{
//check two new passwords
if ($newpassword==$repeatnewpassword)
{
//successs
//change password in db
$querychange = mysql_query("UPDATE login SET password='$newpassword' WHERE username='$username'");
}
else
die("<div class='results'>New password doesn't match!</div>");
}else
die("<div class='results'>Old password doesn't match!</div>");
}
}
if ($email != "") {
$querychange = mysql_query("UPDATE login SET email='$email' WHERE username='$username'");
die("<div class='successmate'>Your password has been changed. <a href='index2.php'><br><br> Return</a></div>");
}
}
else
{
echo"
<form class='search1' action='changepassword.php' method='POST'>
<label>Current Password:</label> <input type='password' id='password' name='oldpassword'><p>
<label>New Password:</label> <input type='password' id='password' name='newpassword'><p>
<label>Repeat New Password:</label> <input type='password' name='repeatnewpassword'><p>

</form>
";
}
{else
die ("You must be logged in to change your password");
?>
答案 0 :(得分:0)
问题是你正在紧接着运行2个查询,你需要添加一个检查以查看密码是否为空,然后跳过密码查询,如果电子邮件是空白则跳过电子邮件查询
修改强>
if ($newpassword != "") {
//check passwords
if ($oldpassword==$oldpassworddb)
{
//check two new passwords
if ($newpassword==$repeatnewpassword)
{
//successs
//change password in db
$querychange = mysql_query("UPDATE login SET password='$newpassword' WHERE username='$username'");
else
die("<div class='results'>New password doesn't match!</div>");
}else
die("<div class='results'>Old password doesn't match!</div>");
}
}
if ($email != "") {
$querychange = mysql_query("UPDATE login SET email='$email' WHERE username='$username'");
die("<div class='successmate'>Your password has been changed. <a href='index2.php'><br><br> Return</a></div>");
