    Why is PHP substituting an underscore in my form?

    Hi,

    I'm using PHP 4.4.4. I notice for form elements that contain spaces,
    PHP substitutes an underscore for the element name when the form is
    submitted. For example, if I have this page (test.php)

    <html>
    <body onload="documen t.forms[0].submit();">

    <form name="f" action="test_re sponse.php" method="post">
    <input type="hidden" name="Hi There" value="2">
    </form>

    </body>
    </html>

    and then test_response.p hp

    <?php
    foreach (array_keys($_R EQUEST) as $k) {
    $val = $_REQUEST[$k];
    print "key: $k val:$val<BR>\n" ;
    } // foread
    ?>

    the output is

    key: Hi_There val:2
    key: __utma val:171843875.2 38415504.116025 2422.1161727205 .1161788841.6
    key: __utmz
    val:171843875.1 160252422.1.1.u tmccn=(direct)| utmcsr=(direct) |utmcmd=(none)
    key: PHPSESSID val:f8cc02f8aa6 3d9cd7a50e6a1d3 40b1b8

    How do I preserve the space in the element name?

    Thanks, - Dave

      Short answer, you can't; longer answer:

              Ah, this one again. The name attribute of <inputelement s et. al. are NOT of
              the datatype NAME, they are CDATA, and not subject to these rules.

              If they were, you would not be able to legally use the square bracket suffixes
              that PHP uses when you want the post/get data to come out as an array.

              The restrictions are added by PHP, as historically the register_global s
              behaviour meant that the data was mapped into PHP variables, so the names must
              follow the PHP variable naming scheme, and are mangled by PHP to force them to
              be so if they're not.

              Some previous discussions:

              The only places that NAME is actually used in HTML 4.01 (Transitional) is in
              META for the http-equiv and name attributes, and the lang or hreflang
              attributes on a few other elements.

                  Oh my, I was way wrong then. Thank you for correcting me. :)
