Re: Pass vars in URL

There are two ways to do this. The easy way is to simply load any vars passed via the URL or from a form as local vars in each script. So, I have the following at the beginning of every script: extract($_GET); // load vars passed via URL into local vars. extract($_POST); // load vars passed via Forms into local vars. If I pass ...?param=1 via the URL, then the extract($_GET) function will automatically create a local var of the same name: $param Or, you can access each variable directly. Say you pass the following via the url: www.site.com/page.html?param=1 In your script you can access the "param" var this way: $_GET('param') It's a pain to rejig all your scripts to work this new way, but, the security benefits are worth it. Have a look here for more details... http://www.php.net/manual/en/language.variables.predefined.php http://www.php.net/manual/en/function.extract.php Monty > From: garyb10@earthlink.net (Gary) > Newsgroups: php.general > Date: Mon, 14 Oct 2002 15:07:21 -0400 > To: php-general@lists.php.net > Subject: Pass vars in URL > > Hello, > My host has upgraded to 4.2 but still uses the old ini setting.
