<?php
hook_file_transfer_alter($file_user, $ip, $fid, $file)
?>Description:
Stores, either for customization, copy protection or other reasons, might want to send customized downloads to customers. This hook will allow this to happen. Before a file is opened to be transfered to a customer, this hook will be called to make any altercations to the file that will be used to transfer the download to the customer. This, in effect, will allow a developer to create a new, personalized, file that will get transfered to a customer.
Parameters:
- $file_user - the file_user object (i.e. an object containing a row from the uc_file_users table) that corresponds with the user download being accessed.
- $ip - the IP address from which the customer is downloading the file
- $fid - the file id of the file being transfered
- $file - the file path of the file to be transfered
Return value:
The path of the new file to transfer to customer.
Example:
<?php
/* Inside personal_text module - will place personalized text at the end of a file */
function personal_text_file_transfer_alter($file_user, $ip, $fid, $file) {
$file_data = file_get_contents($file)." [insert personalized data]"; //for large files this might be too memory intensive
$new_file = tempnam(file_directory_temp(),'tmp');
file_put_contents($new_file,$file_data);
return $new_file;
}
