    Hi there guys,

    on the form page, I generated a random 4 digit number. I then appended that number to the beginning of my html form elements, so:

    using
    so output would be random 4 digit + testtext
    output: 1234testext

    I got that part figured out just fine. My problem is that when submitting the form it has to begin with letter because im trying to parse a textarea and limit it (long explanation), i want to add a letter im trying this
    which should output: x1234testext

    but it does not work i get this error

    so meaning the letter i put which is x doesnt show up, hope someone here get what i was trying to say. :( its hard for me to explain since im new to php.

    Pls help.

    Maybe try this
    $testtext = mysql_real_escape_string (strip_mq_gpc (substr ($_POST[$_SESSION['AS_seed'].'testtext'], 0, 2000)));

    Then append x to $testtext;

    $testtext = 'x'.$testtext;

    Since you've added 'x' to the form object, don't you think you should put the 'x' preceding the index in the $_POST variable?

    i.e: 
    $testtext = mysql_real_escape_string (strip_mq_gpc (substr ($_POST['x'.$_SESSION['AS_seed'].'testtext'], 0, 2000)));
