Problems with global variables ...

Selinaar

Hi everyone,

I am working currently on a new Website with frames, the layout is done and everything works perfect.

I plan to offer my visitors to select which language they want to use, for now I have english and german, of course. I keep the translations in 2 files, like lang.eng.php and lang.deu.php, inside I have the data like :

// german text in lang.deu.php
$msg_welcome = 'Willkommen auf meiner Homepage';

// english text in lang.eng.php
$msg_welcome = 'Welcome to my Homepage';

This is how I include the files :

function language_file(){

global $language;

  if (!is_file("/path/to/my/server/lang/lang.$language.php")) {
    return "/path/to/my/server/lang/lang.deu.php";
  }

return "/path/to/my/server/lang/lang.$language.php";

}

And each page in my frameset loads the language file with :

require ("/path/to/my/server/includes/config.inc.php");
include(language_file());

Okay... so far, this works, I have three pages in my frameset, a page for the menu with the links, a page for displaying the main content, and a page for a banner on top with some text.

Each page has it's content, of course, and general things like Headers or Definitions, example ... to "say hello", i do ...

echo $msg_welcome;

... and of course it echos the text in the language of the included language file.

So if I access index.php?language=eng, it loads my Website with english text, no problem.

But if I click on a link so that it loads that page in the main content frame, it appears in german again with is the default language file - it seems to have 'forgotten' about the variable already set.

I am aware that my global variable would only be available for the funtion itself. So I checked Google and several Forums for an idea how to solve this problem, I heard of Superglobals already.

Is there a workaround for this, that does not need passing the $language value with link1.php?language=eng, for example or to have to create a session and register the variable language ?

If anyone has an idea, I would be all thankful. Thank you for reading my post already, if I have forgotten important informations here, please let me know.

Look into sessions and transparent session ids. (or cookies, but I prefer transparent ids.)

Tried what you suggested, it does not work. When the frame has completed loading, it is in the language that was choosen in $language.

However if I click a link to display a new page in my frame, then THAT new loaded page is in default language again, e.g. 'deu' (german)

you either have to keep passing it in the url, et a cookie, or save the value of language in a session.

That's the only way to keep a user selected preference across multiple pages.

show use the code of the page where the problem is occurring.

I've used the solution I suggested, and it did work. I would suggest there's something wrong in your implementation. Like keith73 said, we'd need to see some code.
