Here’s a fairly basic example of how you could achieve that through a shortcode:
add_shortcode( 'email_button', function () {
if ( isset( $_REQUEST['send-email-shortcode'] ) ) {
wp_mail( '[email protected]', 'Email subject', 'Email message' );
return 'Email sent!';
}
$form = '
<form action="" method="post">
<button type="submit" name="send-email-shortcode">Send Email</button>
</form>';
return $form;
} );
Once added as a snippet, you can add the [email_button] shortcode to a post or page. It will display a button, and when clicked will send an email and show a message saying it has done so.
