pass values in URL?

[Anon]

Hi
general question folks
If I am using a template to output HTML and I want the links to query the DataBase and then output the results how do I do it?

I'm thinking maybe using the URL to pass the variables needed like
<a href="page.php?content=a_value">follow this!</a>

Is this the right way to go?

Suggestions comments and advice needed please!

Nick,

I found this gem while doing research on the exact same question :

There are generally 3 ways to pass variables from page to page (file to file)

1.) URL (query string).
example:

bob.php?key=value

You an retrieve key by using

$HTTP_GET_VARS['key']

2.) Form
using the <form action='post'>
any form elements will be in the
$HTTP_POST_VARS['key']

3.) Cookie
$HTTP_COOKIE_VARS['key']

Hope this helps!

Just make sure you urlencode and urldecode the variables if any of the values have spaces. For example:

from the starting page:

$value1=urlencode($value1);
$value2=urlencode($value2);

and on the destination page:

$value1=urldecode($value1);
$value2=urldecode($value2);

I hope that helps too!
