A simple question

Anon

Hello All!

A simple question to a simple script i'm working on (Im kinda new to all this :-)

I have two PHP files, index.php and main.php. I make user forms in main.php which passes arguments over to index.php. That works fine, but when the user clicks "submit" and is beeing transferred to a new page, the old page with the old HTML shows up in the bottom.

To boil it down, how do i clear the screen so the old HTML dont show up?

Regards

Hi,

That sounds quite strange and should not be happening! Can you provide the group with the code in your two pages??

Thanks

Louis

Yes ofcourse 🙂

Index.php (Contains a Switch statement that evaluates the Params):

<?PHP

include ("mainfile.php");
$this_url = $SERVER_NAME . "/" . $PHP_SELF;
$url = parse_url($this_url);
parse_str($url[query]);

switch($action)
{
case "do_authenticate_login":
$success = validateUser($Username,$Password);

            if ($success == "TrueLevel1" || $success == "TrueLevel2") {
             setcookie("ChValKake",$success,time()+3600);
             printHeader();
             printMainPage();
             printFooter();
            }

            elseif ($success == "Supa") {
             setcookie("ChValKake",$success,time()+3600);
             printHeader();
             printMainPage();
             printFooter();
            }

            else {
             printHeader();
             printFLogin();
             printFooter();
            }

    default:
            printHeader();
            printIndex();
            printLogin();
            printFooter();

}

?>

Mainfile.php is rather messy, so i'll just include the relevant functions:

function printHeader()
{

$Header[] = "<!doctype PUBLIC \"-//W3C//DTD HTML 4.01 Transitional//EN\">";

if(isset($clear)){
exit();
}
$Header[] = "";
$Header[] = " ";
$Header[] = " ";
$Header[] = "";
$Header[] = " <HEAD>";
$Header[] = loc_h_print($html,$location="header");
$Header[] = " </HEAD>";
$Header[] = " <BODY BGCOLOR=\"#FFFFFF\" LEFTMARGIN=\"0\" TOPMARGIN=\"0\" MARGINWIDTH=\"0\" MARGINHEIGHT=\"0\">";

$indexLimit = count($Header);

for ($index=0;$index < $indexLimit; $index++)
{
print("$Header[$index]\n");
}
}

function printFooter()
{
$Header[] = "<BR>";
$Header[] = "<BR>";
$Header[] = "<BR>";
$Header[] = loc_h_print($html,$location="footer");
$Header[] = " </BODY>";
$Header[] = "";
$indexLimit = count($Header);

for ($index=0;$index < $indexLimit; $index++)
{
print("$Header[$index]\n");
}
}

function printLogin()
{

Off the top of my head...

You're missing a 'break;' command in your switch statement....

Should be...

switch($action)
{
case "do_authenticate_login":
$success = validateUser($Username,$Password);
if ($success == "TrueLevel1" || $success == "TrueLevel2") {
setcookie("ChValKake",$success,time()+3600);
printHeader();
printMainPage();
printFooter();
}
elseif ($success == "Supa") {
setcookie("ChValKake",$success,time()+3600);
printHeader();
printMainPage();
printFooter();
}
else {
printHeader();
printFLogin();
printFooter();
}

break;

default:
printHeader();
printIndex();
printLogin();
printFooter();
}

Might fix it... 🙂

Thnx 😉

My book that i bought to learn PHP doesnt say anything including a 'break'. Perhaps becouse the book learns PHP3?

Well, I'm fairly new to PHP, and haven't used PHP3...

But 'break' is a standard command within a 'switch' structure, so I'm pretty sure that it would've been part of PHP3....
