Grabbing the URL

zalealb

I've created a pdf form that post its values to a php page. The php grabs those values using <?php echo $HTTP_POST_VARS['Variable']; ?>. I use the second page as a verification page. When the client checks all the fields they click on a process button which then inserts all that data in a mySQL table. There is a retarded bug in Adobe's Acrobat Reader. When the client click submit within the pdf, the mac client will redirect and post correctly to the specified page, but on the windows side it will create a temp file in client cache. Adobe refuses to help he since they feel its a bug in my php code. I tried to tell them that no php is even introduced within the pdf docuemtn. But i guess they don't make mistakes. so i solved this issue by using <base href="URL">. the problem is that this webpage is visible both in intranet and internet form. so the servers address is different. Which means i can't get specific within the URL. So the question is how do i read the address. ie http://wwww.server.com/pdfs/processpdf.php. this was i can use a varaible as the adddress to conform to both outside and inside clients. ie http://192.160.10.1/pdfs/processpdf.php.
Does anybody know of a good way to do this?

You could set up an internal DNS etry to point to the same as the extenal IP. for example I have an internal ip of 192.168.10.6 and an external ip of 195.224.249.178 however both of these are known as secure.tlg.co.uk and because internally windows looks for our own DNS servers first it finds the internal address. And an external user would find the external address first. so I can safely use secure.tlg.co.uk to find the correct address inside or out.

i used:

<?php echo $HTTP_SERVER_VARS['HTTP_HOST']; ?>

to grab the servers address as its seen by the client. this solved my problem and works great. i will be doing the dns changes, thanks for the help

That variable only contains the hostname such as www.this.com. It doesn't contain the path to the script that's running however. You would have to combine several environmental vars to get a url.

$page_url =  $protocol_type . $HTTP_SERVER_VARS['HTTP_HOST'] . $HTTP_SERVER_VARS['PHP_SELF'];

Determining $protocol_type in that statement can be done through a ternary operator to detect whether SSL is on or not and determine whether [url]http://[/url] or [url]https://[/url] should be used.

i might be using that later, but since the page will always be the same.

<?php echo $HTTP_SERVER_VARS['HTTP_HOST']; ?>

works fine for me so this is basicaly what i did.

<base href="http://<?php echo $HTTP_SERVER_VARS['HTTP_HOST']; ?>/ggiconcept/rfqs/processdrfq.php">

and that works great. but i like your suggestion i can definetly see were that would help alot.
i really wish though that adobe would acknowledge that there might be something wrong with acrobat reader. oh well.
