Question

有关验证消息的问题。用户提交表单后，我的表单验证消息（通过php）出现在标题中。

如何让消息显示在正文中（在表单下方）。代码如下。 Screen shot attached for clarification

<?
/* Check User Script */
session_start();  // Start Session

include 'db.php';
// Conver to simple variables
$username = $_POST['username'];
$password = $_POST['password'];

if((!$username) || (!$password)){
echo "Please enter ALL of the information! <br />";
include 'login_form.html';
exit();
}

// Convert password to md5 hash
$password = md5($password);

// check if the user info validates the db
$sql = mysql_query("SELECT
* 
FROM users u
WHERE 
username='$username' 
AND password='$password' 
AND activated='1'
AND u.email_address IN (SELECT email from authorized_doctors)
  ");
$login_check = mysql_num_rows($sql);

if($login_check > 0){
while($row = mysql_fetch_array($sql)){
foreach( $row AS $key => $val ){
    $$key = stripslashes( $val );
}
    // Register some session variables!
    session_start('first_name');
    $_SESSION['first_name'] = $first_name;
    session_start('last_name');
    $_SESSION['last_name'] = $last_name;
    session_start('email_address');
    $_SESSION['email_address'] = $email_address;
    session_start('special_user');
    $_SESSION['user_level'] = $user_level;

    mysql_query("UPDATE users SET last_login=now() WHERE
    userid='$userid'");

    header("Location: login_success.php");
    }
  } else {
echo "<br>You could not be logged in! Either the username and
password do not match or you have not validated your membership!
Please try again!<br />";
include 'login_form.html';
}
?>

Answer 1

只需在include之后输出您想要的数据：

...
} else {
    include 'login_form.html';
    echo "<br>You could not be logged in! Either the 
              username and password do not match or you have not validated your membership!
             Please try again!<br />";
}
?>

Answer 2

您可以将消息分配给变量，并将该变量输出到所需的位置。例如：

$message = '<br>You could not be logged in! Either the username and
password do not match or you have not validated your membership!
Please try again!<br />';

include 'login_form.php';

在login_form.php中的内容如下：

...
<a href="">Forgot password?</a>
<?php echo $message; ?>
...

PHP验证消息出现在标题中
