Use this filter to control whether or not a protected file will check the referer on download.
Usage
add_filter( 'frm_check_file_referer', '__return_false' );
Parameters
- $check_referer
Examples
Turn off file referer check
Use this example to make a protected file URL work from an email for a user that isn't logged in.
add_filter( 'frm_check_file_referer', '__return_false' );
Turn off file referer check for Zapier
A protected file cannot be added to Google Drive because the request from Zapier fails the referer check. Use this example to turn off the referer check whenever Zapier is making a request.
add_filter( 'frm_check_file_referer', 'turnoff_file_referer_check_for_zapier' );
function turnoff_file_referer_check_for_zapier( $check_referer ) {
if ( ! $check_referer ) {
return false;
}
return FrmAppHelper::get_server_value( 'HTTP_USER_AGENT' ) !== 'Zapier';
}
