While the code is running say something like a database error ocours. I'm handling these using the @ before the functiosn then checking if the result is false. But if it is false then I want to scrap all the output so far and send a new page. Do I have to use a buffer or can I get away doing it without? Thanx.
Yes - you'll need to turn on output buffering. In my applications I usually create a function similar to die() which clears all output buffers and then outputs the error:
Something like this:
PHP Code:<?php
function error ($msg)
{
$level = ob_get_level();
while ($level > 0) {
ob_end_clean();
--$level;
}
?>
<html>
<head>
<title>Photo Albums - Error</title>
</head>
<body>
<span class="error"><?php echo($msg) ?></span>
</body>
<?php
exit;
}
?>
