Add attachment wordpress mail

To add an attachment to a WordPress email using the wp_mail function, you can use the wp_mail function with the attachments parameter.

Here is an example:

$to = '[email protected]';
$subject = 'Test Email with Attachment';
$message = 'This is a test email with an attachment.';

$attachments = array('path/to/attachment.pdf');

wp_mail($to, $subject, $message, '', $attachments);

In this example, the attachments parameter is an array of file paths. You can add multiple attachments by adding more elements to the array.

You can also use the wp_mail function with the wp_upload_dir function to get the upload directory and then use that to construct the attachment path.

$to = '[email protected]';
$subject = 'Test Email with Attachment';
$message = 'This is a test email with an attachment.';

$upload_dir = wp_upload_dir();
$attachment_path = $upload_dir['path']. '/attachment.pdf';
$attachments = array($attachment_path);

wp_mail($to, $subject, $message, '', $attachments);

You can also use the media_sideload_image function to upload the attachment to the media library and then get the attachment ID and use it to send the email.

$to = '[email protected]';
$subject = 'Test Email with Attachment';
$message = 'This is a test email with an attachment.';

$attachment_path = 'path/to/attachment.pdf';
$attachment_id = media_sideload_image($attachment_path, 0, 'attachment', 'id');

$attachments = array($attachment_id);

wp_mail($to, $subject, $message, '', $attachments);

Note that the wp_mail function will automatically add the attachment to the email and set the Content-Type header to application/octet-stream. You can also use the wp_mail function with the wp_mail_charset filter to set the character set of the email.
