I am creating wordpress plugin that has some custom tables with it. Using plugin admin menu it should be able to upload and download data to the custom table. I can upload data into table without problem, but download has problems. Tried few methods but none of its working( with using headers).
Found some samples with editing functions.php in wordpress but I can't edit the wordpress funciton.php. code must be in the plugin itself. Any idea how to resolve download customer table from wordpress plugin admin menu.
