[chrisjunkie]

Hi there people,

As i am a n00b  ;D  I need to ask questions hehehe

What i want to do is have it so i can type index.php?page=1 and have page 1 show up. I know this can be done and I have looked at php code that does this but i cant quite nut it out. Any help greatly appreciated

if you enter in the url

test.php?category=test

this code in test.php file:
[code]<?php
if ($category == "test") {
    echo "<div id='test'>
  TEST!
</div>";
}
?>[/code]

will return:
TEST!

but register globals has to be on

do NOT expect to be able to use $category locally upon entering a URL like that.  register_globals has been turned off by default since PHP something.or.other.that's.fairly.old.

use superglobals like $_GET['category'].  read more about it in the manual, and/or here in the FAQ/code snippets forum because this is a very common question.

It depends on where you are going to be storing page 1.
Will it be pulled from a database or from a file?

[code]
<?php

if ($_GET["page"]) {
    require_once("/pages/". $_GET["page"] .".php");
}

?>
[/code]

or

[code]
<?php

if ($_GET["page"]) {
    // get page from database
    $sql = 'SELECT contents FROM pages WHERE id='. $_GET["page"];
    // use your database engine / class / generic to get the result
    // $db->getOne($sql);    <--- Pear DB Manager
    echo $result;
}

?>
[/code]

Just remember to untained $_GET["page"] to prevent SQL injections or file redirects.

Always valadate a $_GET ok.

I remember at least passing all your user-received values through something like this:

[code]
<?php
function removeBadWords($src) {
$filter = array("INSERT INTO ", "SELECT ", "UPDATE ", "JOIN ", "UNION ", "MODIFY TABLE ", ";", "DELETE ");
$replacements = array_fill(0, count($filter), "");
return addslashes(strip_tags(str_ireplace($filter, $replacements, $src)));
}
?>
[/code]
