    Yet another $_POST Problem

    PHP version 5.1.1
    Apache 2.0.55.

    code;
    index.html

    <html>
    <head>
    <title>Untitl ed Document</title>
    <meta http-equiv="Content-Type" content="text/html;
    charset=iso-8859-1">
    </head>
    <body>
    <form action="foo.php " method="post" name="form">
    <input name='username' type="text" value="colin">
    <input name="email" type="text" value="crona... @email.com">
    <input name="submit" type="submit" value="submit me!">
    </form>
    </body>
    </html>

    foo.php

    <?php
    echo "We are on foo.php";
    echo "<br>";
    $username = isset($_POST['username']) ? $_POST['username'] :
    NULL;
    $email = isset($_POST['email']) ? $_POST['email'] : NULL;
    echo $username;
    echo $email;
    ?>

    Output;
    We are on foo.php

    So simple. So easy. Yet $username and $email will not get printed.

    All my forms worked perfectly last week (boo-hoo, I know), but now only
    GET will work on even the simplest of forms. And I would rather not go
    through every form and change them to get.

    Cause it's past midnight on my second day of trying to fix this I have
    to ask.......
    Any ideas?
    Did I change a php.ini setting in my sleep?

    /* It can take hours to find the problem and a second to fix it. */

      Try a

      print_r($_POST) ;

      and see what you get. If nothing, then NULLs will be assigned as per
      your code. This also probably points to a php.ini or other PHP or
      Apache setting that is preventing POST variables, because AFAICT, you
      code appears to be correct.

          cheers Mark.

          I have tried that allright. For GET it populates the Array but for
          POST the array is empty.
          Once I got all my text forms working correctly I moved onto file
          upload. The only thing I can remember changing is the maximum file
          size allowed in php.ini. But the fact that it worked and now doesn't
          means I changed something else. But I can't for the life of me figure
          out what it is. Anything specific I should look for? php.ini and
          apache config looks fine. But I could be looking through rose tinted
          glasses.

          Thanks again mate.

              Well, I answered my own question.
              By changing
              post_max_size = 1000000000M to
              post_max_size = 100000000M
              all post data was sent.

              The reason I changed it was that I thought it worked in conjunction
              with
              upload_max_file size

              but this doesn't seem to be the case. File upload will still upload
              files of a gig.

              Cool.

              Thanks Mark.

                  Don't you think that 100,000 GIGABYTES is a little excessive for
                  POST data? Besides, it's apparently taking it as a signed 32-bit
                  number anyway, and if it's negative, it won't allow any.

                      isset is not the function you want to use. Try empty().
