I'm not even sure if this is possible, but here goes.
I have a form (http://www.digameloya.com/enviar_sms.php excuse the crappy layout, I'm just working on getting the damn thing working) which loads the users from a database and gives each user a checkbox which can be selected to send the email to them.
Unfortunately the only select/unselect all option I could find, required all of my checkboxes to be given the same name (stupid I know) so when i select multiple checkboxes, it only passes one value through $_POST. Is there an easy way to make it pass all checkboxes without renaming the checkbox?
