How to make a private page for only specific member

[SNU]

I already make a new page named "service.php" to my oscommerce website.

I wanna only one member, who called "technician", can access that page (service.php).

Now, the "service.php" page can be accessed by all members in my website.

Where codes I must edit?

 <?php 
  require('includes/application_top.php');
  require('includes/metaqueries.php');

  if (!tep_session_is_registered('customer_id')) {
    $navigation->set_snapshot();
    tep_redirect(tep_href_link(FILENAME_LOGIN, '', 'SSL'));
  }

  require(DIR_WS_LANGUAGES . $language . '/' . FILENAME_SERVICE);
  $breadcrumb->add(NAVBAR_TITLE, tep_href_link(FILENAME_SERVICE));
?>  

In my database, table customers, the "technician" member has customer_id = 1
should I change 'customer_id' in the code above with 1 or ??

Any help would be greatly appreciated!
Thanks!

 if (!tep_session_is_registered('customer_id') && customer_id == '1') {

Why not simply use .htaccess to protect the file - you could even lock it down to only allow access from their IP address (assuming it is static).

@pgmarshall, thank you for your idea, but I don't understand how to do it

@ridexbuilder, thank you so much. I already use &&, but it doesn't work and when I try to use "||" it works!

 if ( (!tep_session_is_registered('customer_id')) || ($customer_id != '1') ) {
    tep_redirect( tep_href_link(FILENAME_DEFAULT) );
  }

You will need to amend slightly to use the && otherwise non-logged in users will be able to access.

It should be:

if ( (tep_session_is_registered('customer_id')) && ($customer_id != '1') ) {
tep_redirect( tep_href_link(FILENAME_DEFAULT) );
}

Note the removal of the ! which is short for NOT.
