Fatal error: Class 'Swift_smtpTransport' n

问题:

I am trying to add the functionality to send my customers emails from my website backend and am attempting to use swiftmailer to do this. I unfortunately keep getting an error message

Fatal error: Class 'Swift_smtpTransport' not found in /home/u312041955/public_html/cust/modules/customer/email.php on line 94

Although it seem to me like the swiftmailer class is not being included properly it must be as otherwise the page does not display any information at all. The code from the page I am using swiftmailer from is as follows.

<?php require_once("include.php");
    //Required for swift mailer
    require_once (INCLUDE_URL.'/swift/lib/swift_required.php');
    if(!xml2php("customer")) {
    $smarty->assign('error_msg',"Error in language file");
    }
    // Lets grab some variables we need
    $email_username = $VAR['email_username'];
    $email_password = $VAR['email_password'];
    $email_server = $VAR['email_server2'];
    $email_server_port = $VAR['email_server_port2'];
    $customer_id = $VAR['customer_id'];
    $c2 = $VAR['c2'];
    $download_id = $VAR['download_id'];

I have been struggling with this now or some time and could use a shove in the right direction.

Update 1: I have been continuing to play around with this and when i change the line

$transport = Swift_smtpTransport::newInstance( "mx1.hostinger.co.uk" , 2525 )
->setUsername('[e-mail]')
->setPassword('******');

To simply

$transport = Swift_MailTransport::newInstance()

so it isn't using SMTP anymore i get a message sent successfully notification but for some reason it sends it to the from email address and also gets marked as spam because it may not have originated from the account hence why I want to use smtp. Update 2: after reading other threads I found that

$transport = Swift_smtpTransport::newInstance( "mx1.hostinger.co.uk" , 2525 );

Should in fact be

$transport = Swift_SmtpTransport::newyInstance( "mx1.hostinger.co.uk" , 2525 )
;

This gets rid of the class not found error but I now get a timeout error. I am certain I am using the correct mail server detail as I got them from my host. Any help very much appreciated.

回答1:

Eventually worked out that

$transport = Swift_smtpTransport::newInstance( "mx1.hostinger.co.uk" , 2525 );

Should in fact be

$transport = Swift_SmtpTransport::newyInstance( "mx1.hostinger.co.uk" , 2525 );

and then afterwards that my hosting provider does not allow mail to be sent by SMTP on my plan.
