How can I require that a user be logged in, in order to submit an input?
This input will be posted to a MySQL database.
This is the input code as it stands in my plugin:
<input type="text" maxlength="4" name="' . $quanid . '" value="" class="input" />
As of right now, anyone can submit this, regardless of login status.
