電子郵件不會根據變量名發送

Question

只有輸入實際地址而不是使用$ usr_email時，我的電子郵件纔會發送，儘管它表示「發送了消息」。電子郵件地址來自users表中的user_email字段。 這是用 定義的$ id = intval（$ _ SESSION ['user_id']）;

if (isset($_POST['doSend'])) { 


function getTwo($query){ 
    $res = mysql_query($query); 
    if (!$res) { 
     trigger_error("db: ".mysql_error()." in ".$query); 
     return FALSE; 
    } 
    if ($row = mysql_fetch_row($res)) { 
     return $row[0]; 
    } 
} 

$getuserinfo_q = "SELECT user_email AND user_name FROM users WHERE 
id='$_SESSION[user_id]'"; 

$getuserinfo_e=mysql_query($getuserinfo_q); 

if(mysql_num_rows($getuserinfo_e) < 1){ 

    echo "User details not found - User_id is not in DB"; 

    exit(); 

} 

$user_info_val=mysql_fetch_assoc($getuserinfo_e); 

if(empty($user_info_val['user_email'])){ 

    echo "there is no such column name as 'user_email'"; //tell the user about column 

    exit(); //shut off the script 

} 


$usr_email=$user_info_val['user_email']; 
    $user_name=$user_info_val['user_name']; 



$sqltest = "SELECT completed_status From users where id = 
'$_SESSION[user_id]'"; 
$isSending = getTwo($sqltest); 
$isSending === false; 
if($isSending >= 6){ 
    require_once "Mail.php"; 
    require_once "Mail.php"; 



    $from = "<xxx>"; 
    $to = "$usr_email"; 
    $subject = "hi"; 
$body ="Chi "; 

$host = "ssl://smtp.gmail.com"; 
$port = "465"; 
    $username = "xxx"; 
    $password = "xxxx"; 

$headers = array ('From' => $from, 
'To' => $to, 
'Subject' => $subject); 
$smtp = Mail::factory('smtp', 
array ('host' => $host, 
    'port' => $port, 
    'auth' => true, 
    'username' => $username, 
    'password' => $password)); 

$mail = $smtp->send($to, $headers, $body); 

    if (PEAR::isError($mail)) { 
     echo("<p>" . $mail->getMessage() . "</p>"); 
    } else { 
     echo("<p>Message successfully sent!</p>"); 
    } 
} 
else 
    header ("Location: error.php"); 



}

好吧，讓希望這個作品-_-

$getuserinfo_q = "SELECT user_email AND user_name FROM users WHERE id =' 
".intval($_SESSION['user_id'])."'"; 

$getuserinfo_e=mysql_query($getuserinfo_q); 

if(mysql_numb_rows($getuserinfo_e) < 1){ 

echo "User details not found - User_id is not in DB"; 

exit(); 

} 

$user_info_val=mysql_fetch_assoc($getuserinfo_e); 

if(empty($user_info_val['user_email'])){ 

echo "there is no such column name as 'user_email'"; //tell the user about column 

exit(); //shut off the script 

} 


$usr_email=$user_info_val['user_email']; 


$sqltest = "SELECT completed_status FROM users WHERE id =' 
".intval($_SESSION['user_id'])."'"; 
$isSending = getTwo($sqltest); 
$isSending === false; 
if($isSending >= 6){ 
    require_once "Mail.php"; 

// Start NEW CLASS (for your weird Mail function) 

$m_class=new Mail; 


    $from = "<xxx>"; 
    $to = "$usr_email"; 
    $subject = "hi"; 
$body ="Chi "; 

$host = "ssl://smtp.gmail.com"; 
$port = "465"; 
    $username = "xxx"; 
    $password = "xxxx"; 

$headers = array ('From' => $from, 
'To' => $to, 
'Subject' => $subject); 


$smtp = $m_class->factory('smtp', 
array ('host' => $host, 
    'port' => $port, 
    'auth' => true, 
    'username' => $username, 
    'password' => $password)); 

$mail = $m_class->send($to, $headers, $body); 

} 
else 
    header ("Location: error.php"); 

正如你可能已經注意到，我刪除了錯誤檢查（在PEER::isError()東西），只是因爲我我不知道該如何調用這個函數（不是靜態的）。但是，除此之外，上面的代碼應該做的伎倆（希望）。

給它一個去，讓我知道它是如何工作的。
