Question

我有一个带有先前代码和函数的html / php页面changepassword()但是有一个函数会提示用户在密码过期时更改密码。

我希望当用户点击更改密码按钮时，它会调用change password功能（所有代码都位于同一页面上）。我遇到的问题是，当用户点击action="index.php"按钮时，它会默认返回登录屏幕。我猜测它是action="index.php"属性的结果。

如何让按钮直接调用该函数而不执行$oldpassword = $_POST["oldpassword"]; $newpassword = $_POST["newpassword"]; $confirmpassword = $_POST["confirmpassword"]; $passwordResult = ''; if($_POST["update"] == "user") { $passwordResult = ChangePassword($db_connection, $userid, $_POST["oldpassword"], $_POST["newpassword"], $_POST["confirmpassword"]); } echo' <div class="dataform"> <form method="post" action="index.php"> <table> <tr><td> Old Password: </td><td> <input type="password" name="oldpassword" value=""/><br/> </td></tr><tr><td> New Password: </td><td> <input type="password" name="newpassword" value=""/><br/> </td></tr><tr><td> Confirm Password: </td><td> <input type="password" name="confirmpassword" value=""/><br/> </td></tr><tr><td> <input type="submit" value="Change Password"/> </td></tr> </table> <input type="hidden" name="update" value="user"/> </form> '.$passwordResult.' </div>'; }，它将始终默认返回登录页面？这是代码的突触

function ChangePassword($db_connection, $userid, $old, $new, $confirm)
    {

        if($confirm != $new)
        {
            echo '<font color="red">The confirmation password does not match the new password.</font>';
            return;
        }   

        $qrystring = 'UPDATE user
                    SET password = SHA1(?)
                    WHERE userid = ?
                    AND password = SHA1(?)';

        if ($statement = $db_connection->prepare($qrystring)) 
        {
            $statement->bind_param('sss', $new, $userid, $old);

            $statement->execute();

            $reportid = $db_connection->insert_id;

            if($statement->affected_rows != 0)
            {

                $db_connection->commit();
                echo $header_string.'
                            <font color="green"><b>Your password was successfully updated.</b></font><br/>';
            }
            else
            {
                $db_connection->rollback();
                echo $header_string.'
                <font color="red">We were unable to update your password. Please verify that the old password is correct.<i>(u3)</i></font><br/>';
            }

            $statement->close();
        }
        else
        {
            $db_connection->rollback();
            echo $header_string.'
            <font color="red">We were unable to update your password at this time.<i>(u4)</i></font><br/>';
        }

    }
