Using querystrings

[moonbather]

Hello,

I modified an example (called demoquery.php) at a French language site

[asp-php.net...]

which I think is designed to deliver different webpage content from within one file (depending on the value of the querystring). I couldn't get the example to work, so I tried changing it a little, eg using

<?php

[2]<?[/2]

<A href="?page=1">Page 1</A> - 
<A href="?page=2">Page 2</A> -
<A href="?page=3">Page 3</A>
</div><hr>
<?php 
$page=$_GET['page'];
switch($page) {
     case "1" :?>
page 1
<?php break; case "2" :?>
page 2
<?php break; case "3" :?>
page 3
<?php break; default:?>
default page
<?php }?>

but still no luck. So I wondered if anyone had any ideas? Thank you.

hi moonbather,

the examply you posted worked perfectly on my machine, running win2k/apache 2/php 4.2/mysql 4

so the code is correct.

you might have an older version of php, so try $HTTP_GET_VARS['page'] instead of $_GET['page']

you might like to read the manual on superglobals [es.php.net]

the user comments are useful

good luck

Thanks for the information, jamie. I'm going to have to study this globals palaver.

as above, but also note you should not just put?page=X in the href destination - it is essential to use $PHP_SELF

<A href="<?php echo $PHP_SELF;?>?page=1">Page?</A>?
