How to add variables to email template

[Max Clee]

Hello I use Prestashop 1.7.6 

I would like extend variables in e-mail templates

• gender
• invoice number 

because exist global variable  for 

• {$customer.gender.name[$customer.gender.id]} Client Gender (example: Ms, Mr, etc.)

I trying to add gender to file to classes/PaymentModule.php and email template   in diverse form but without success (code below ) 

but what is with Invoice Number ? 

i look forward to your help  

// Send an e-mail to customer (one order = one email)

if ($id_order_state != Configuration::get('PS_OS_ERROR') && $id_order_state != Configuration::get('PS_OS_CANCELED') && $this->context->customer->id) {

$invoice = new Address((int) $order->id_address_invoice);

$delivery = new Address((int) $order->id_address_delivery);

$delivery_state = $delivery->id_state ? new State((int) $delivery->id_state) : false;

$invoice_state = $invoice->id_state ? new State((int) $invoice->id_state) : false;



$data = array(

'{gender}' => $this->context->customer->gender,

'{firstname}' => $this->context->customer->firstname,

'{lastname}' => $this->context->customer->lastname,

Think you should dig in to the email template file.

Have a look at

root(public_html?)/mails/en/  

where /en can differ as be your selected language

Create a Module and add the Hook "sendMailAlterTemplateVars":
Here you can add variables to all E-Mail-Templates like this:

 

/*
*  $this->registerHook('sendMailAlterTemplateVars');
*/

/**
     * @param $param
     * @return string
     */
    public function hooksendMailAlterTemplateVars($params)
    {
		$context = Context::getContext();
	  
		if ($params['template'] == 'order_conf') {
			
			$reference = $params['template_vars']['{order_name}'];
			
			$sql = 'SELECT * FROM '._DB_PREFIX_.'orders WHERE reference = "'.$reference.'" Limit 1 ';
                 $orderRow = Db::getInstance()->executeS($sql);
			
			if (!empty($orderRow)) { 
			
				$id_order = reset($orderRow)['id_order'];
				$order = new Order ($id_order );
			
				$params['template_vars']['{firstmessage}'] = "<strong>Nachricht</strong><br>".trim($order->getFirstMessage())?:'';
				$params['template_vars']['{id_order}'] = $id_order ;
								
				$id_customer = reset($orderRow)['id_customer'];
				$customer = new Customer ($id_customer );
				$gender = new Gender ($customer->id_gender );
				
				$params['template_vars']['{genderByLang}'] = $gender->name[$context->language->id]?:"";
				
				/*
				* Custom Text only on specific paymenttype
				* $order->module == "stripe_official"
				**/
				
				if($order->module == "ps_wirepayment") {
					$params['template_vars']['{wirepaymentSpecialText}'] = "<p>Some Information about payment...</p>";
				}
				
			}
	  
		}
		
		if ($params['template'] == 'bankwire') {
			// do something...
		}
					
    }

 

 

In your Mail-Template:

{id_order}<br>
{genderByLang}<br>

<div>
	{firstmessage}
</div>
  
{wirepaymentSpecialText}
