Pages parsed twice?

[nervino]

Hi All,
I'm facing a strange issue calling a php page by an ajax call.

I have a module with 2 pages:
1) action.schedule.php
2) action.ajax_send.php

Page 1 (action.schedule.php) has a form, displayed by a file template.tpl. In this file template there is an ajax call to page 2, which sends an email message using Swiftmailer library.

The issue: page 2 (action.ajax_send.php) seems to be parsed twice. There is any kind of loop in it, but it always sends the mail twice (I receive two identical mails).
If I directly call action.ajax_send.php, in this way:

Code: Select all

http://www.site.com/modules/MyModule/action.ajax_send.php

it correctly sends only one mail.



This is my code:

Page 1: action.schedule.php:

Code: Select all

<?php
if (!isset($gCms)) exit;

$this->smarty->assign('name_input', $this->CreateInputText($id, 'name', $name, 25, 128));
$this->smarty->assign('email_input', $this->CreateInputText($id, 'email', $email, 25, 128));
$this->smarty->assign('phone_input', $this->CreateInputText($id, 'phone', $phone, 25, 30));
$this->smarty->assign('message_input', $this->CreateTextArea(false,$id,$message, 'message','','message','','', 50,10));

$txt_sa = $this->CreateFrontEndFormStart($id,$returnid,'');
$smarty->assign('formstart_contact',$txt_sa);
$smarty->assign('submit_contact', $this->CreateInputSubmit($id,'submit_contact', $this->Lang('submit')));
$smarty->assign('formend_contact',$this->CreateFormEnd());

$smarty->assign('url_ajax', $this->create_url($id, 'ajax_send', $returnid ));

// PASS FORM ID FOR JQUERY...
$form_id=array('id'=>$id);
$form_id = $form_id["id"];
$this->smarty->assign('form_id', $form_id);

echo $this->ProcessTemplate('template.tpl');
?>

Template.tpl:

Code: Select all

{$formstart_contact}
<ul>
<li>
<label for="{$form_id}name">name</label></li>
<li>{$name_input}</li>
<li><label for="{$form_id}email">eMail</label></li>
<li>{$email_input}</li>         		
<li><label for="{$form_id}phone">phone</label></li>
<li>{$phone_input}</li>         		
<li><label for="message">message</label></li>
<li>{$message_input}</li>
<li>{$submit_contact}</li>
</ul>

{$formend_contact}
{literal}
<__script__ type='text/javascript'>
$("form").submit(function(e) {

e.preventDefault();

var name = $("#{/literal}{$form_id}{literal}name").val();
var email = $("#{/literal}{$form_id}{literal}email").val();
var phone = $("#{/literal}{$form_id}{literal}phone").val();
var message = $("#message").val();
  
$.ajax({
type: "POST",
url: "{/literal}{$url_ajax}{literal}+'&showtemplate=false",
dataType : 'json',
data: {
name: name,
email: email,
phone: phone,
message: message
}						  
});// END AJAX POST
});
</__script>
{/literal}

Page 2: action.ajax_send.php (in this test I'm not retrieving form variables, setting them statically in the email):

Code: Select all

<?php
    require_once(dirname(__FILE__)."/lib/Swift-4.2.2/lib/swift_required.php" );
    
    // Create the Transport
    $transport = Swift_SmtpTransport::newInstance('mail.mysite.com', 25);
    $transport->setUsername('info@mysite.com');
    $transport->setPassword('p4ssw0rd');
    
    $email_visitor = 'usermail@domain.net';
    $name_visitor = 'John';
    $message_visitor='Hello!';
    
    // Create the Mailer
    $mailer = Swift_Mailer::newInstance($transport);
    
    
    $message = Swift_Message::newInstance()
    ->setSubject('Message from web site')
    ->setFrom(array($email_visitor => $name_visitor))
    ->setTo(array('my@mail.com' => 'Kit'))
    ->setBody($message_visitor, 'text/html')
    ;

    // Send the message
    $numSent = $mailer->send($message);
?>

I saw a similar behaviour with another action page from inside a fancybox iframe: the queries were executed two times.

I guess this is due to the way cmsms parses pages and templates, that I do not completely understand, and I can't find a solution

Does anyone have faced the same issue and can point me into the right direction to solve it?

Thanks a lot

I bet you have more than one 'form' on the rendered page.

[nervino]

And you lose the bet
I've also tried to fire the form with its cmsms generated name:

Code: Select all

$("#cntnt01moduleform_1").submit(function(e) {
  	e.preventDefault();............

Same result: two emails received.

thanks Robert

Well, I made several other tests:
1) using a static url in the ajax, instead of the cmsms generated one:
$.ajax({
type: "POST",
url: "http://www.site.com/modules/MyModule/ac ... x_send.php",

sends 1 mail


2) By Removing "showtemplate=false" from the ajax url:
$.ajax({
type: "POST",
url: "{/literal}{$url_ajax}{literal}",

output "SyntaxError: JSON.parse: unexpected character" and so sends 1 mail

I also made a fresh install (cmsms 1.11.3), deleting everything from the template but the form that sends the emails: same result, 2 emails sent.

I really have no idea how to fix this unwanted behaviour...

I have the same issue ever since 1.11.

I'm using ajax with a simple 'contact-me' form.

In 1.10 I would receive one e-mail. Ever since 1.10 (up to current version of 1.13) I am getting 2 e-mails. I think it has something to do with the "&showtemplate=false" as part of the form action. I definitely concur with you nervino, there is a bug somewhere.

I don't think it has anything to do with form builder either... something in the cmsms core but I'm not sure what.
