    I am just curious here.

    For radio and check boxes, if you do not enter a value their corresponding varialbe does not appear in the $_GET url

    however with text boxes, it will appear at variable= why is this, if there is not value why not , not have it appear?

    A radio\checkbox are activated when they are checked, nothing to pass before that, those elements are assigned value when they are activated.

    A textbox always has a value, even if you don't type anything yourself.

    Hehe, I hope that makes some sense:)

    Textbox always has a value, with "" being the default unless you enter something else.

    Yes, think of a textbox as a string (a string can have 0 length), and checkboxes/radio buttons almost like booleans, returning the value or just null.
