Mail
tab. InMessage Body
add generated code from [mfile]. ( Example Below )Message Body : [your-message]

- In order to attach files to email you will need to check and make sure „send as file(s) as links” option is unchecked.
- Go to WordPress admin menu „Contact -> Edit {specific_form}” click or hover the cf7 form you want to edit.
- In „Edit Contact Form” page click „Mail” tab and in the bottom you will see „File attachments” field, on this field add your upload field name (ie: [upload-file-xxx]), you will find the upload name in „Form” tab generated from
[mfile]
shortcode. - If attaching multiple files from a different file upload just add all the upload fields name. (see example below)
File attachments:[upload-file-111] [upload-file-222]
