Custom PHP file that can be executed before file download, to prepare or change file content #

Custom PHP – PHP file/function that will process file content before being downloaded by the user. This only works with private file link, see security parameter above.

File must be located at “/components/com_customtables/customphp”.

Function name must be like this CTProcessFile_filename($original_file_content,&$row)

Lets call the file “privatefile.php”

defined('_JEXEC') or die('Restricted access');

function CTProcessFile_privatefile($original_file_content,&$row){
    return str_replace('*activation_key*','23098ueu028',$original_file_content);
}
