Creating an error message page?

[ahealy]

The code below creates an error message and then displays it if needed. When the messge is displayed though, its diplayed along with all the other stuff on the screen at the time. Is there a way to blank the page first, before displaying the message.

<?
//If session expires say something
if ($surname == ""){
makeform("Your session has expired. Please re-login.");
}

//this function shows the form.
function makeform($errormessage){

//print the error message
echo "<font color=\"#FF0000\"><strong>$errormessage</strong></font><br>";
?>

Greatful for any help, cheers.

could you get it to go to the logon page, or a blank.php and just get it to show the message?

Just an idea.

alternatively can you prevent session timeouts?

Best have the session timeouts for security reasons I think.

I could have a seperate blank page with the message on but would rather do it the other way. I have a login script here that does it but for the life of me I don't know how. I'm sure it's only a simple command, it only has to clear the page.

fair enough, to tell the truth they were just rough guesses anyways, hope you find out.

just put your alert in a java script.
Even makes a sound on the client side 😃

if (!ValidSession())
{ header ('Location: index.php?Error=1')}

Then in index.php

<SCRIPT language='javascript'>
<?PHP
switch ($Error)
{
case 1:echo "alert('Session timed out!')";
break;
case 2: echo "alert('invalid username')";
}
?>
</script>

Something like that...

function makeform($errormessage){ 

//print the error message 
die(echo "<font color=\"#FF0000\"><strong>$errormessage</strong></font><br>"); 
?> 

maybe using die() ? would that work

Will give it a go ThaSpY. Cheers.
