Requirements

  1. Make sure you download the files from this library
  2. Have a place for you to the load the functions needed (plugin or theme files)
  3. A HTML template. I provide a basic one, but if you have one styled already. Please use that, mine is pretty basic.
  4. Your server needs to be able to send mail obviously. I can recommend SMTP post plugin to handle that.
require get_template_directory() . \'/inc/lib/WP_Mail.php\';

function send_email($email_type, $to, $subject, $data){


    $paths = array(
        // your HTML template is stored here
        \'contact_form\' => get_template_directory() . \'/inc/email-templates/contact_form.html\',
        
    );

    $WPMAIL = (new WP_Mail)
        ->to($to)
        ->subject($subject)
        ->template($paths[$email_type], $data)
        ->headers([
            \"From: testdomain.com <info@testdomain.com>\",
            \"Content-type: text/html; charset=utf-8\",
        ])
        ->send();


    return $WPMAIL;

}

// Now we can call it anywhere. Pass all the data that you need to call it.
send_email($email_type, $to, $subject, $data) 

This can very well be combined with the other post on a custom contact form, then you can receive directly an email when a user submits a form.

Below is my example of the contact form HTML template. The little library that we included allows us to pass variables to the template and use {{variable_name}} inside the HTML templates. This makes it significantly easier to write simple HTML emails.
