[Moodle] Dynamically changing wwwroot

[Michael Greenhill]

Try changing it to this - note the extra equals sign in the third line.

$PVGCip = $_SERVER['REMOTE_ADDR'];
$PVGCparts = explode('.',$PVGCip);

if ($PVGCparts[0] == '10') {
  $CFG->wwwroot = "http://10.x.y.z";
} else {
  $CFG->wwwroot = "http://moodle.pvgc.vic.edu.au";
}

Also note that I've put the quotes in the third line. This is because you're
comparing a string ($PVGCparts[0], explode splits one string into an array
of strings), so the value you're comparing it against should be a string
too.

Subject: [Moodle] Dynamically changing wwwroot

Hi Moodlers and PHP coders,

I have a problem which I thought I'd solved but, alas, only made worse.
I'd be grateful for your suggestions.

Here goes:

Our college's moodle is located on a box 10.x.y.z within our intranet which
is visible to the Internet as  http://moodle.pvgc.vic.edu.au. Its wwwroot in
config.php is "http://moodle.pvgc.vic.edu.au" and users use this address
whether they are at school (intranet access) or at home. All machines on our
local network are prefixed with "10." and our border IP identifies as
210.a.b.c.

When users access the site using the intranet and the moodle.pvgc.vic.edu.au
URL they get a lot of 403 errors and my logs report a lot of header
problems. A bit of research suggested DNS issues.

I thought I would fix this by having my intRAnet users use an alias
"http://moodle/" which points to 10.x.y.z and modifying config.php to test
whether the user's IP starts with 10. The result was access through the
intRAnet was greatly improved but the site was unusable over the intERnet
- the document root is identified as 10.x.y.z instead of
moodle.pvgc.vic.edu.au. Here is the modification:

$PVGCip = $_SERVER['REMOTE_ADDR'];
$PVGCparts = explode('.',$PVGCip);

if ($PVGCparts[0] = 10)
  {$CFG->wwwroot = "http://10.x.y.z";}
else
  {$CFG->wwwroot = "http://moodle.pvgc.vic.edu.au";}

(The logic in my script's first two lines works - try it in a little script
to display and reformat the contents of $parts[n])
