No, you just need to have wpMandrill activated.
Where and when are you calling it?
There are some scenarios where the plugin might not be loaded. Be sure it is.
I see. I already have it activated and I know it definitely works as a test email always is sent out properly.
I was testing the function call with a plugin called ‘Product Enquiry for Woocommerce’ which is available for download on this site (link here: Product Enquiry).
I replaced line 212 which says:
@mail($to, $subject, $body, $headers) or
die("Unfortunately, a server issue prevented delivery of your message.");
…with this….
wpMandrill::mail($to, $subject, $body, $headers) or
die("Unfortunately, a server issue prevented delivery of your message.");
PHP mail() function returns false on error. wpMandrill::mail() returns WP_Error on error. You can’t just swap the functions.
I see. OK. What is your suggestion then?
You shouldn’t use php mail() in a WordPress plugin. You don’t need to hard code mandrill into a plugin either. Well… not ideally. There are potential situations maybe…
But you can just use wp_mail(). Which is the desired way to send emails in WordPress 99% of the time. Mandrill replaces that to send through their smtp.
