Accessing Variables in Included File

nomz

can we declare a variable in main file and use them in an included file in the same page?

MAIN FILE

if ($referer[0]=="iftikhar.comsats.net.pk")
{
$style= "pesstyle.css";
echo $style;
global $chgpwdlink="iffichange.htm";
}

<? include 'http://some/other/server/main1.php'; ?>

Included FILE

<a href="<? echo $chgpwdlink; ?>" class="main">Change Password</a>,

i could not use the chgpwdlink in the included file. it gives the error that variable not declared.

try this:


MAIN FILE 
------------ 

<?php

if (ereg('iftikhar.comsats.net.pk',$_SERVER['HTTP_REFERER']))
{ 
   $style= "pesstyle.css"; 
   echo $style; 
   $chgpwdlink="iffichange.htm"; 
}
else
{
   $chgpwdlink = '';
}

?>

<? include 'http://some/other/server/main1.php'; ?> 

Included FILE 
--------------- 
<a href="<? echo $chgpwdlink; ?>" class="main">Change Password</a>,

Yesm you can create variables outside include files and access them from within. You dont have to put that global infront of the variable, infact i would remove it all together. I dont see any problem with the script. But you should have an else statement there with the variable declaration in that also !!! - if your IF statement returns false the variable will not be set !!!

infact the problem is still there.. i tried every thing.. but could not.... solve it

<?
$referer = str_replace ("http://", "", @$_SERVER['HTTP_REFERER']);
$referer = explode ("/", $referer);
print $referer[0];

if ($referer[0]=="iftikhar.comsats.net.pk")
{
	$style= "pesstyle.css";
$chgpwdlink="http://iftikhar.comsats.net.pk/chgpwd.htm";
}

else if ($referer[0]=="atk.comsats.net.pk")
{		
	$style="atkstyle.css";
$chgpwdlink="http://atk.comsats.net.pk/chgpwd.htm";
}

?>
<body>
<?
include 'http://server/styles/main1.php';
?>
</body>
This was all in the main file....

Included FILE

<a href="<? echo $chgpwdlink; ?>" class="main">Change Password</a>,

it makes the link as.....

http://server/styles/<br%20/>Notice:%20%20Undefined%20variable:%20%20chgpwdlink%20in%20E:/Sites/Style%20Sheets/main1.php%20on%20line%2072<br%20/>

which is... the Variabe not Defined.....

you still don NOT have a else() statement !!!!!

if ( ... ) {
  // set var
} elseif ( ... ) {
 // set var
} else {
 // set var
 // you NEED this if the IF and ELSEIF fail
}

nomz

it never fails as i directly access the

http://iftikhar.comsats.net.pk

can you please check it...

http://iftikhar.comsats.net.pk/test

and check the notice

Hi,

it is a difference whether you include a file locally or via url.
In the first case, it is as if you'd paste the content of the include file in your main scripts, but in the second, the include file is parsed first (and wouldn't know any variable from the main script) and the result is included.

Hope this helps,
xblue

im getting:

iftikhar.comsats.net.pkpesstyle.css 

TEST [url]http://210.56.14.182/iffichange.htm[/url] 
Notice: Undefined variable: chgpwdlink in E:\Sites\Style Sheets\main1.php on line 23

You should try a simple test like this on your Server:

page1.php:

$myvar = "this is my value";
include 'page2.php';

page2.php:

if(isset($myvar)) {
 echo "the value of \$myvar is $myvar.";
} else {
 echo "the variable is not set anymore !!!.";
}

if the above works, then its you code somewhere !!!
