I am looking to integrate an email to sms option for a current wordpress plugin. Currently the plugin asks for users name and email address. Once this is done the user receives an email to download a file. I would like to be able to add receive sms as welll. So I am thinking this would need to now be a selection menu. if email is selected then everything works as is, if sms is selected I need to be able to have this number entered. Because this is email to sms I am thinking a selection box with carrier will also need to be added. Based on the selection the plugin will direct the sms to the appropriate carrier. My thought is because carriers change this often it would be best for the admin to be able to set this up in the backend themselves. Meaning if ATT is selected for instance then since the admin has configured the menus accordingly the plugin will automatically send the link to #@[url removed, login to view] or what ever it is. As I mentioned this need to be able to be added to an existing plugin. Doable?
