Adding String Attachments (AddStringAttachment) with wp_mail (part 2)
<?php
add_action( 'phpmailer_init', '_add_string_attachments' );
function _add_string_attachments( $phpmailer ) {
// the previous attachment will fail since it's not an actual file
// we will use the error to attach it as a string
if ( '' !== $phpmailer->ErrorInfo ) {
// error info
$error_info = $phpmailer->ErrorInfo;
$translations = $phpmailer->getTranslations();
// See if there was an error attaching something to the email
if ( false !== stripos( $error_info, $translations['file_access'] ) ) {
// remove the messaging
$attachment_string = str_replace( $translations['file_access'], '', $error_info );
// the result will be the json encoded string that was attempted to be attached by default
$attachment = json_decode( $attachment_string );
// sanity check to see if there is an actual id that we're looking for
if ( isset( $attachment->pdf_doc_attachment_id ) ) {
// get the doc id so that you can create the content string for the attachment
$doc_id = $attachment->pdf_doc_attachment_id;
// do something to create the string attachment
$file_name = 'stuff.pdf';
$pdf_string = 'stuff';
try {
$phpmailer->AddStringAttachment( $pdf_string, $file_name, 'base64', 'application/pdf' );
} catch ( phpmailerException $e ) {
continue;
}
}
}
