phpmailer_init WordPress Action Hook
The phpmailer_init hook allows you to modify the PHPMailer class before it is used by WordPress. This can be useful if you need to add extra headers, or change the way that email is sent.
do_action_ref_array( 'phpmailer_init', PHPMailer $phpmailer ) #
Fires after PHPMailer is initialized.
Parameters
- $phpmailer
(PHPMailer)The PHPMailer instance (passed by reference).
More Information
The wp_mail() function relies on the PHPMailer class to send email through PHP’s mail function. The phpmailer_init action hook allows you to hook to the phpmailer object and pass in your own arguments.
This action is initiated with `do_action_ref_array` rather than `do_action`. You still hook to it with `do_action`. However, there are some notable differences:
- If you pass an array to `do_action_ref_array()`, each element’s value of that array is passed as a separate parameter to the callback.
- If you pass an array to `do_action()`, the complete array is passed as a single argument including any keys.
