Description
By default the real location of an uploaded file is hidden. The download URL will be generated with a security token to prevent guessing or enumeration attacks to discover the location of other files. The gform_require_login_pre_download filter can be used to require the user be logged in before the download URL will allow access to the file.
Usage
The following would apply to all forms.
add_filter( 'gform_require_login_pre_download', 'your_function_name', 10, 3 );
Parameters
$require_login bool
Does the user need to be logged in to access the file? Default false.
$form_id int
The ID of the form used to upload the requested file.
$field_id int
The ID of the field used to upload the requested file.
Examples
1. Require login for all forms
add_filter( 'gform_require_login_pre_download', '__return_true' );
2. Require login for specific form and field
add_filter( 'gform_require_login_pre_download', 'require_login_for_downloads', 10, 3 );
function require_login_for_downloads( $require_login, $form_id, $field_id ){
// Update values below to match your form and field id's
if ( $form_id == '97' && $field_id == '2' ) {
$require_login = true;
}
return $require_login;
}
3. Require login for all forms and redirect to login page
add_filter( 'gform_require_login_pre_download', function( $require_login ) {
$require_login = true;
if ( ! is_user_logged_in() ) {
auth_redirect();
}
return $require_login;
} );
