You're probably better doing this kind of think in the .htacess file.

 

htaccess Redirect

hi there

what it is that we have drop down menus with hyperlinks, but rather then have loads one for external and one for internal everything, we wanted to replace them with a single one for each link.

 

and use the power or php/html to check which url the user is on and there direct them accordly.

 

any ideas?

[danbuntu]

are the internal and external links linking to the same things? ie are you using something like moodle.college.ac.uk for one and moodle.local for the other?

 

or are they going to completely separate sites? ie moodle.college.ac.uk for one and google.co.uk for the other?

[tri_94]

they are separte sites.

Think i've got it sorted now. using the following php code.

Could not use a DNS record to redirect the users internally instead of them going out and then back in?

$CFG->wwwroot is the moodle url as set in your config file, so that code will always return true.

 

you want to use the global $_SERVER variable: PHP: $_SERVER - Manual ; something like

 

if ($_SERVER['SERVER_NAME'] == 'mydomian.co.uk') {

echo 'url1';

} else {

echo 'url2';

}

Have a look at the tag HTML base tag

 

You can use the PHP $_SERVER to check the server that a user is accessing from and then set the default base path accordingly.

This will then affect all relative links on the page.

 

if ($_SERVER['SERVER_NAME'] == 'mydomain.co.uk') {
echo "";
} else {
echo "";
}

 

This should be in the

section of the page.

Install Net_IPv4 via Pear (Net_IPv4), then whack the following somewhere before where you want the link... (eg: in Moodle's config.php)

 

require 'Net/IPv4.php';
$ip   = $_SERVER['REMOTE_ADDR'];   // Get user's IPv4

// Define all LAN/LOCAL IP ranges...
$net1 = '172.16.96.0/21';   // Curriculum Range
$net2 = '10.113.140.0/24';  // Admin Range

$CFG->localuser=4;

if ((Net_IPv4::ipInNetwork($ip, $net1)=='1') || (Net_IPv4::ipInNetwork($ip, $net2)=='1')){
   $CFG->localuser=1;
}

 

then, for the link...

 

echo 'Linky Text';

 

 

(I think)
