Question

我有一个有用户的网站。每个用户帐户在mysql表subscription_expires中都有一个到期日期。

有没有办法将用户重定向到dashboard.php以外的其他网页（如果他们的个人资料或subscription_expires为=到今天登录后的日期，其中说明他们的个人资料已过期。

我尝试过使用sub_expires等等，但如果他们的个人资料已过期，它仍然会记录用户。

这是我的登录脚本：

<?php

    if (logged_in()) {
        redirect_to("dashboard.php");
    }

    include_once("includes/form_functions.php");

    // START FORM PROCESSING
    if (isset($_POST['submit'])) { // Form has been submitted.
        $errors = array();

        // perform validations on the form data
        $required_fields = array('email', 'password');
        $errors = array_merge($errors, check_required_fields($required_fields, $_POST));

        $fields_with_lengths = array('email' => 30, 'password' => 30);
        $errors = array_merge($errors, check_max_field_lengths($fields_with_lengths, $_POST));

        $email = trim(mysql_prep($_POST['email']));
        $password = trim(mysql_prep($_POST['password']));
        $hashed_password = md5($password);

        if ( empty($errors) ) {
            // Check database to see if email and the hashed password exist there.
            $query = "SELECT id, email, close_account ";
            $query .= "FROM ptb_users ";
            $query .= "WHERE email = '{$email}' ";
            $query .= "AND password = '{$hashed_password}' ";
            $query .= "AND close_account = '0' ";
            $query .= "LIMIT 1";
            $result_set = mysql_query($query);
            confirm_query($result_set);
            if (mysql_num_rows($result_set) == 1) {
                // email/password authenticated
                // and only 1 match
                $found_user = mysql_fetch_array($result_set);
                $_SESSION['user_id'] = $found_user['id'];
                $_SESSION['email'] = $found_user['email'];
                $_SESSION['sub_expires'] = $found_user['subscription_expires'];

                $result = mysql_query("UPDATE ptb_users SET user_online='Online' WHERE id=".$_SESSION['user_id']."") 
or die(mysql_error());


                redirect_to("dashboard.php");
            } else {
                // email/password combo was not found in the database
                $message = "<div class=\"infobox\"><strong>Email/Password combination incorrect.</strong><br />
                    Please make sure your caps lock key is off and try again.</div>";
            }

                } else {
            if (count($errors) == 1) {
                $message = "<div class=\"infobox\">There was 1 error in the form.<div>";


            } else {
                $message = "<div class=\"infobox\">There were " . count($errors) . " errors in the form.<div>";
            }
        }


    } else { // Form has not been submitted.
        if (isset($_GET['logout']) && $_GET['logout'] == 1) {
            $message = "<div class=\"infobox\">You are now logged out.</div>";
        } 
        $email = "";
        $password = "";
    }
?>
            <?php if (!empty($message)) {echo "<p class=\"message\">" . $message . "</p>";} ?>
            <?php if (!empty($errors)) { display_errors($errors); } ?>
            <form action="login.php" method="post">

Email<br />
<input name="email" type="text" value="<?php echo htmlentities($email); ?>" size="40" maxlength="50" />

  <br />
  <br />
  Password<br />
  <input name="password" type="password" value="<?php echo htmlentities($password); ?>" size="40" maxlength="30" />

  <br />
  <br />
<input type="submit" name="submit" value="Login" />


            </form>

Answer 1

您未在选择查询中添加“subscription_expires”字段。所以你将为$ _SESSION ['sub_expires']获取null。此外，我没有在您的逻辑中看到您尝试使用$ _SESSION ['sub_expires']值来执行任何有意义的操作，例如阻止用户登录。您只是自动更新ptb_users表以将其显示为在您对该值进行任何检查之前在线。

Answer 2

您也在使用'{$hashed_password}'参数，而不进行设置（您设置了trim(mysql_prep($_POST['password']))。该查询几乎肯定不会返回值...

如果到期日期=今天的日期，则重定向到页面？
