How to send e-mails

Using the Mail::send() method

The Mail core class extends ObjectModel
This example is assuming you are using in a controller named mycontroller of a module named mymodule
<?php
class mymodulemycontrollerModuleFrontController extends ModuleFrontController
{

    public function initContent()
    {
        parent::initContent();
        Mail::Send(
            (int)(Configuration::get('PS_LANG_DEFAULT')), // defaut language id
            'contact', // email template file to be use
            ' Module Installation', // email subject
            array(
                '{email}' => Configuration::get('PS_SHOP_EMAIL'), // sender email address
                '{message}' => 'Hello world' // email content
            ),
            Configuration::get('PS_SHOP_EMAIL'), // receiver email address
            NULL, //receiver name
            NULL, //from email address
            NULL  //from name
        );
    }
}
Prestashop will use the Shop Configuration to decide if use smtp connection or php mail function so check it out on backoffice or in app/config/parameter.php

Add custom template

Mail::send has some parameters. You can specify your emails templates path of your module in parameter templatePath.

In your module you must create the subfolder mails and then a sub folder with languages. Example: modules\yourmodulename\mails\en for english.

In this folder you do create 2 files: one with extension .html and one with extension .txt.

The name of the template files is in second parameter. In the under example the template name is contact. So you do create 2 files in mails subfolders of your module: modules\yourmodulename\mails\en\contact.html and modules\yourmodulename\mails\en\contact.txt.

After installation, the templates email files are moved under the active folder theme: theme\classic\modules\yourmodulename\mails\en\.....

<?php
class mymodulemycontrollerModuleFrontController extends ModuleFrontController
{

    public function initContent()
    {
        parent::initContent();
        Mail::Send(
            (int)(Configuration::get('PS_LANG_DEFAULT')), // defaut language id
            'contact', // email template file to be use
            ' Module Installation', // email subject
            array(
                '{email}' => Configuration::get('PS_SHOP_EMAIL'), // sender email address
                '{message}' => 'Hello world' // email content
            ),
            Configuration::get('PS_SHOP_EMAIL'), // receiver email address
            NULL, //receiver name
            NULL, //from email address
            NULL,  //from name
            NULL, //file attachment
            NULL, //mode smtp
            '/modules/yourmodulename/mails' //custom template path
        );
    }
}
