php and mysql web development book errata

[haans]

Hi,

I refer to the mentioned abook by Luke Willing, ISBN: 0672317842

I was trying to work on Chapter 24 about sessions authentication and cookies, I couldn't get the code work. I wonder if anyone face the similar problems?

1. The email I entered, it says invalid. (data_valid_fns.php)
   // check an email address is possibly valid
   if (eregi("^{[a-zA-Z0-9_.-]+@[a-zA-Z0-9-]+.[a-zA-Z0-9-.]+$",} $address))

Unless I changed to if (!eregi(.....)

2. The same goes to the password verification check.
   if (strlen($passwd)< 6 || strlen($passwd) >16)
   {
   do_html_header("Problem:");
   echo "Your password must be between 6 and 16 characters."
   ."Please go back and try again.";

3. After I finished registered and see the page confirm registration sucessful. I noticed there is a blank record in user table in "bookmarks" database in mysql.

I have turned on magic quotes for all the testing but still failed.

Thank you in advance for any help.

I am not sure if this will work... but try:

if (eregi("/^{[a-zA-Z0-9_.-]+@[a-zA-Z0-9-]+.[a-zA-Z0-9-.]+$/",} $address))

Hmm...doesn't seems to be working.

PHP 4.23
mysql 3.23
apache 1.3.22 windows nt 4.0 sp6

Here is an excerpt of the check email code:
function valid_email($address)
{
// check an email address is possibly valid
if (!eregi("^{[a-zA-Z0-9_.-]+@[a-zA-Z0-9-]+.[a-zA-Z0-9-.]+$",} $address))
return true;
else
return false;
}

This is working because I used !eregi, the moment I use "eregi" it fails. It seems unlogical.

Thanks anyway.
