[berkamp]

Hi all , I use the code below but I get 2 error ...

1 * Notice: Use of undefined constant num - assumed 'num' in D:\wamp\www\fbelgesel\hadi.php on line 20

2 * Notice: Undefined index: page in D:\wamp\www\fbelgesel\hadi.php on line 25

Do you have any idea , how can I solve this ... ?

1 * Notice: Use of undefined constant num - assumed 'num' in D:\wamp\www\fbelgesel\hadi.php on line 20

2 * Notice: Undefined index: page in D:\wamp\www\fbelgesel\hadi.php on line 25

First up, those two aren't errors, but they're just notices to you that you're doing something different.

The first one says that you're using an undefined constant. By the looks of it, you're trying to use an array element and all array elements with a key must be called like this within single quotes

$arr['key']

You can fix the first error by changing line 20 to

$total_pages = $total_pages['num'];

The second error happens because you're using the $_GET array element, but it's not initiated or declared anywhere before it's usage. So you have to either make sure you get the variable from the browser or at least set an initial sanity value so that your pagination code works properly. Something like say a

if ($_GET['page'] != "" and is_num($_GET['page']))
{
  $page = $_GET['page'];
}
else
{
  $page = 1; //or any other sane default.
}

This following is a bad practice and should not done on a production server!

Alternatively you could suppress these notices, by setting a error_reporting directive at the top of the file.

error_reporting(E_ALL ^ E_NOTICE)
