in thread How to check value of checkbox on form submit?

However, just setting a value of on in the html and then checking for that value in the script should always work. Whether undefined or null, it definately won't equal the string "on" so...

    You're right! I thought that sounded a little odd so I ran the following test:
    <html><body> <form action="http://johnny.warp.psi.br/cgi-bin/test.pl"> <input type="text" name="field1"> <input type="checkbox" name="field2" value="on"> <input type="submit"> </form> </body> </html>
    If this form is submitted with everything blank, curiously the text input gets carried as null, but the checkbox is undef! QUERY_STRING : field1=

    I don't see where the consistency is here, but that was something I had never really noticed.
