Error in posting variables through variables

sciwaysoft

I have just installed my Apache and PHP 4 with MySQL on my local computer to check my code while I am not connected to the internet. When connected to internet I reach my pages by posting variables through URL like

http://www.mydomain.com/index.php?cat=5&id=2

this page open the index.php page and includes page "mypage52.php" in the content place. It is done well on my Host. But when trying to check on my local server. It fails to post variables. First hope was to turn Register_global to on. But after turning it on the problem persist. Any help.. I am using the latest versions of PHP Apache and MySQL....

Any sample code?
Are you using the $_GET array?

Does your include use a path or a URL to include the file. If it's a path I'm no help without some code to look at. If it's a URL, it's not going to work because you're not online and can't access the URL on your own machine. Make sense? Good luck.

When I enter the url

http://localhost/content.php?cat=5&id=7

I want to access the page

http://localhost/contant.php

which has a code snippet in it..


<?php

   $cat=$HTTP_POST_VARS['cat'];
   $id=$HTTP_POST_VARS['id'];
   if (!$cat){
   $pagename="error404.php";
   $pagetitle="Page Not Found";   

   }else{
   include("dbconnect.php");
   include ("mypage" . $cat . $id");
   }
?>

The page is there. And it works fine when online. But on Local host it doestn works and display and error page which I have set to error404.php.

If i dont use a custom error page this error is obtained

Warning: main(): Failed opening '' for inclusion (include_path='.;c:\php4\pear') in F:\Projects\myprojects\site\content.php[/url] on line 51

If Instead of posting variables cat and id through url , i define then within code the page works fine. It means some thing is wrong with posting of variables...

Code with which page works fine

<?php
   //$cat=$HTTP_POST_VARS['cat'];
   //$id=$HTTP_POST_VARS['id'];
   $cat='5';
   $id='7';
   if (!$cat){
   $pagename="error404.php";
   $pagetitle="Page Not Found";   

   }else{
   include ("dbconnect.php");
   include ("mypage" . $cat . $id");
   }
?>

Looks like it could by your last line. It has an extra " in it at the end there.

include ("mypage" . $cat . $id");
// needs to be //
include ("mypage" . $cat . $id);

Give that a shot. I don't know why that would work on one server and not the other but I would see that causing an error.

csousley

Well that may be it but your also calling to the wrong method. If the variable is being passed in the URL then you need to call 'get' and not 'post'.

$cat = $GET['cat'];
$id = $GET['id'];

Thanks for your help... That works. I was using $HTTP_POST. As soon as i changed them to $HTTP_GET it started working... thanks again. What is the difference between

$HTTP_GET and $_GET

csousley

To be honest I've never used $HTTP_GET but based on how you are using it, I would guess there's no difference.

I believe there is a difference, in the amount of data that can be sent.
The GET method supposedly has a lower cap than POST.

I would advise you to use the $_GET array instead of $HTTP_GET_VARS to access name/value pairs in the query string, i.e. passed by the GET method.
For the reason, look into this forum's FAQ.

One last thing: try to post the actual code you used, e.g. by copy and paste.
This avoids distracting people (in this case csousley) with new typos.
If the code you sent was indeed the code you used, then there should be a parse error.
