handling error codes

chris_s_22

when been doing the coding i notice that when ive tested each function to make sure everything working that when a error is displayed it goes to a blank page and displays it, what i want is one page that i can customise and disaplays the error on that page, here are all my errors

else
	{ echo "Wrong Confirmation code";}

die ('Could not connect to the database.');

can i replace the above errors with the following code without a problem?

// show error page with the error
          $reg_error = description of the error here';
          include 'error.php';
          exit;

then on the error page have something like

<?php if (isset($login_error)) { ?>
There was an error: <?php echo $login_error; ?>, please try again.
<?php } ?>

is there any reason why this wouldnt work or is there a simpler way

There is a big difference between validating a confirmation code from your users and a syntax error in your code. I think you may be confusing the these two very different problems as one.

Your database connection failing fits into the syntax error or exception category. Here is a good article to show the ins and outs of handling errors (or exceptions) for PHP.

As for your user-generated errors (or form validation), you need a different approach.

Your approach is similar to mine. I put error messages in an array called $err and I have a function that prints each one out.

$err[] = "You messed up, horribly, try again this time with your eyes open!";
include 'error.php';
exit();

Where error.php is a template that prints the errors. I put the whole error message in $err, so error.php template is "dumb" (has no logic) and just spits out the messages, maybe as simple as this:

<?php
foreach($err as $v) {
    print "$v<br />";
}
?>

Specifically, one that allows the user to correct their mistake - and how you and they do that depends on the nature of their error.
