The only way to accomplish what you seem to be trying to do is have a Javascript run onChange in the input box which changes any lowercase characters to uppercase ones. But Pozor has a better idea - just change the case at the point you insert the text into the database.
Yeah, text-transform only affects how the user input is displayed, not how it is sent to the server. Use the strtoupper() PHP function once you're about to insert the input into the database.
