Hi Guys..

I'm having a bit of trouble getting the OR operator to work.
This is the code that I have:

global.php:
index.php:
I suspect, having played about with this code for quite a few hours, that it is:
if((getenv(REMOTE_ADDR) != $vars["admin ip"])||(getenv(REMOTE_ADDR) != $vars["admin ip2"]))that is causing the problem.
Can anybody advise me please.

What exactly do you expect and is not happening.

The code in the included file is executed every time you call index.php and $vars["admin link"] might be set to "".

Later you want to echo $vars["admin link"], but when of the conditions in the if statement in the include file is satisfied that won't happen.

try using and rather than or

Hi Guys...
Thanks for taking the time and trouble to help me.

This is what used to happen:

I have an ADMIN link at the bottom of the index.php page, which is only visible if the correct ip number is accessing the page.
This is the code that worked fine.
global.php
index.php
Then, if a visitor came to the index.php page the ADMIN link would not show.
If I came (my ip being xxx.xxx.xxx.xx1) to the index.php page, the ADMIN link would show at the bottom of the page.

Now I want either of TWO ip numbers to activate the ADMIN link (maybe 3 in the future), hence the code in my first post.
This is so that I can ADMIN the site, and so can my client.

And now, using the code in my first post, it doesn't work for either of the ip numbers, which leads me to believe that my coding in the global.php file is wrong.

Hope this gives a better explanation.

Regards,

Look at your statement:
if REMOTE_ADDR matches admin ip then you will get false with the first test followed by a true with the second test. A false OR true will give you a true
if REMOTE_ADDR matches admin ip2 then you will get true with the first test followed by a false with the second test. A true OR false will give you a true
if REMOTE_ADDR matches neither admin address then you will get true with the first test followed by a true with the second test. A true OR true will give you a true

So no mater what your input is you will get a true

Now try:
if REMOTE_ADDR matches admin ip then you will get false with the first test followed by a true with the second test. A false AND true will give you a false
if REMOTE_ADDR matches admin ip2 then you will get true with the first test followed by a false with the second test. A true AND false will give you a false
if REMOTE_ADDR matches neither admin address then you will get true with the first test followed by a true with the second test. A true AND true will give you a true

So if there is a match with either admin ip you will get a false, otherwise you will get a true.

Hi graemef..

Many thanks for taking the time and trouble to help me resolve my coding problem.

I did try && some time ago, but it didn't work.
I have now tried it again and it DOES work.

Obviously the first time there must have been an error in the index.php file.

However, my code is now:
global.php
index.php
Many thanks for your invaluable help.

Glad it worked. You might want to read up on DeMorgan's Law
