I’m doing a plugin that accesses remote data to change a specific token at the email sending . The function is onEmailGenerate , but in this role I noticed that the mautic calls again for a different lead without even finished making the sending of the first email . Aparentente is a competition problem someone went through it ?  
  
  
  
Here is my source code:

Code:

\<?php namespace MauticPluginVestconBundleEventListener;

use MauticEmailBundleEmailEvents;  
use MauticEmailBundleEventEmailBuilderEvent;  
use MauticEmailBundleEventEmailSendEvent;

/_\*

\*/  
public function onEmailGenerate(EmailSendEvent $event)  
{

$stringHtmlEmail = $this-\>getEmailDynamic($event);

// Set updated content  
$event-\>setContent($stringHtmlEmail);  
}

private function getEmailDynamic($event)  
{

$html = $content;

try {

```
$content = $event->getContent();

if (strpos($content, '{cart.model1}') == true) {
    $html = $this->getHtmlCart($event, '{cart.model1}');
}
else if(strpos($content, '{cart.model2}') == true) {
    $html = $this->getHtmlCart($event, '{cart.model2}');
}

```

}  
catch (Exception $ex ){ }

return $html;  
}

private function getHtmlCart($event, $token)  
{

// Get content  
$content = $event-\>getContent();

$lead = $event-\>getLead();  
$cartId = $lead[‘cart\_id’];

$urlServico = ‘[http://xxxxxx](http://xxxxxx)’;  
$json\_object = $this-\>getJson($urlServico, $cartId);

ob\_start();  
include (dirname( **DIR** ).’\Views\TemplateEmails\Cart’.str\_replace(array("{", “}”), “”, $token).’.html.php’);  
$stingEmail = ob\_get\_clean();

return str\_replace($token, $stingEmail, $content);  
}

private function getJson($url, $id)  
{  
$username = ‘xxxxxx’;  
$password = ‘xxxxxx’;

$postdata = http\_build\_query( array(‘cestaid’ =\> $id ) );

$opts = array(‘http’ =\>  
array(  
‘method’ =\> ‘POST’,  
‘header’ =\> “Content-Type: application/x-www-form-urlencodedrn”.  
“Authorization: Basic “.base64\_encode(”$username:$password”).“rn”,  
‘content’ =\> $postdata,  
‘timeout’ =\> 60  
)  
);

$context = stream\_context\_create($opts);

$unparsed\_json = file\_get\_contents($url, false, $context);

$unparsed\_json = mb\_convert\_encoding($unparsed\_json, ‘HTML-ENTITIES’, “UTF-8”);

$json\_object = json\_decode($unparsed\_json);

return $json\_object;  
}  
}

I’m reading your code, but it is hard to comment on the lines since here are no line numbers. For example I don’t understand why you have `$html = $content;` before the $content var is created. Could you link to the GitHub repo with your plugin so we could comment on each line?
