How are parameters passsed to HTML pages?

How is it done?

[lucifer]

quick answer - it isn't :p

you need to use CGI (eg Perl), PHP, JSP, ASP, servlets etc

I'd recommend PHP it's the easiest IMO :)

[LastActionHero]

but i have seen webpages where it says somedomain/page.html?something

and how is this done?

http://in.yahoo.com/homemap/?http://edit.india.yahoo.com/config/mail?.intl=in

[lucifer]

probably some url rewriting going on but it won't be a html page as they can't do jack ----

[LastActionHero]

and how is that yahoo thing done a question mark after the back slash?

Anything after ? is picked up as a QUERY_STRING variable. http://in.yahoo.com/homemap/ has an index file, index.cgi or something that gets called. For .html, I guess you can pick it up with JavaScript and by looking at the document url (if QUERY_STRING isn't available).

Thank you. :) Can you post a code snippet here to show us how it works?

[lucifer]

var url=window.location.href;

gets the full url then do what you like with it

Thank you Lucifer. I'm guessing this will work in al browsers?

Here's a bouncing sample... Seems to work on both IE5.5 and NN4.7 at least.



<script language="javascript">
url = window.location + "";
if (((i = url.indexOf("?")) >= 0) && ((query_string = url.substring(i + 1)) != "")) {
alert("Bouncing you to " + query_string);
window.location = query_string;
}
</script>


In PHP:



<? header("Location: $QUERY_STRING"); ?>

You can see the dif. in complexity, if you have access to PHP its far the best way.

You can also print out text using php
ie.

http://www.somesite.ext/?var=this is a test


<?echo('$var');?>

[lucifer]

surely


<?=$var?>

[gyrbo]

Bad PHP:
<? header("Location: $QUERY_STRING"); ?> (makes the browser go to $Query-string)
<?echo('$var');?> (Will print $var instead of the value of $var, should be <?php echo($var);?> or <?php echo $var; ?>)

it's perfect possible in Javascript ... and way more easy !
And you don't need PHP support or anything ...

The code is very easy ...


var Param = location.search.substr(1);


Just look at http://users.belgacom.net/gc230251/test.html
and http://users.belgacom.net/gc230251/test.html?blablabla


You can split it with anyting (in the example with a "+" sign)



bv http://www.url.com/bla.html?para1+para2+para3

Parameter = location.search.substr(1).split("+");
document.write('The first Param was' + Parameter[0]);
document.write('The second Param was' + Parameter[1]);
....
