Please drag a Custom Code action before the Email action and add code like this:
<?php $path = JPATH_SITE.'/components/com_chronoforms5/uploads/folder_name/'; $form->files['field_name']['path'] = $path.'file_name.jpg'; ?>
Change the folder path, the file name and the 'field_name' to suit your needs.
Now, in your Email action "Attachments fields names" setting, just enter field_name (with no quotes or brackets).
Adding multiple files
If you have a list of files to add you can extend the code like this
<?php $files = array( 'file_name_a.png', 'file_name_b.png' ); $path = JPATH_SITE.'/components/com_chronoforms5/uploads/folder_name/'; foreach ( $files as $k => $f ) { $form->files['files_to_send'][$k]['path'] = $path.$f; } ?>
Then add files_to send in the Email action Attachements box.
You can modify this example to create the files array based on user inputs - for example to match a set of checkboxes that have been submitted.
