get current parameters in link

cohq82

Hi all, I have this question and I may use the wrong language. So i am sorry about that. Basically, I have this website which I am building a mod to show in English and AnotherLanguage. There will be a button to change the language. When visitors click the button, it will refresh the page and change the language.

The implementation method I tried to follow was: create that new button and add a parameter in the link such as lang=en or lang=other. However, the page could have many other parameters. The questions are:

How to get all the parameters in the current page?
If exist lang=xxx, how to get the value and remove it from the current page?

The purpose is to add <A href="www.website.com/index.php?para1=xxx&para2=yyy&lang=en>Language Button</A> in the new page as the hack!

Please let me know how to do this.

Otherwise, I am open to other alternatives.

Thanks again!!

1. How to get all the parameters in the current page?

$SERVER['QUERY_STRING'] or $GET

2. If exist lang=xxx, how to get the value and remove it from the current page?

Check if isset($GET['lang']) && $GET['lang'] == 'xxx'. If so [man]unset[/man] it and then construct the new query string to be added to your link URLs with [man]http_build_query/man.

This is a great tip. However, I have trouble in one part. What if the current link is something like http://localhost/myapp/ where there is no index.php or a file. The $_SERVER["SERVER_NAME"] didn't return me the file name if missing. How to fix this problem so I can add the full query string to the http://localhost/myapp/index.php?aaa=yyy

Thanks

You can still use it, e.g., http://localhost/myapp/?aaa=yyy
