Hi,

My website has a bunch of pages where it looks VERY similar save for some text.
What I want to do is build my site around index.php

So a file named "lol" would show up as

index.php?p=lol

How would I do this?

Thanks. 🙂

    $p = $_GET['p'];
echo($p);

    Would display "lol" in this case.

    If you want more the one value use index.php?p=lol&q=lawl

      Um, I kinda meant that a file named "lol.php" would be included into the page.

        $page = null;
if (isset ($_GET['p']) ){
 $page = $_GET['p'];
//make sure he is not trying to hack your page
 if (!preg_match('@[a-z0-9][a-z0-9\.]*@i',$page) ) $page = null;
}

if (isset ($page) ) include $page.'.php';
else {
//code for when the "p" paramater is not found or invalid
}

          Another thing you could do to have one page is this.

          <?php
$page = $_GET['page'];

$myPages = array("page1", "page2", "page3"); // list of pages.
if(!$page) {
	echo "You're on the home page!!!";
}else {
if(in_array($page, $myPages)) {

include $page . ".php";

}else {
echo "The page your looking for cannot be found!";
} 
}

echo "<br>";
echo "<a href=\"" . $_SERVER['PHP_SELF'] . "\">Home</a> ";
foreach($myPages AS $allPages) {
	echo "<a href=\"" . $_SERVER['PHP_SELF'] . "?page=" . $allPages . "\">" . $allPages . "</a> ";
}

?>

            ScoobyDooobyD00's example is that it lacks correct checking for the existence of $_GET['page'] before its use. This is well hanlded in Jack McSlay's example, but that example does not account for an invalid/missing include file (i.e., the filename passes the validity check, but the file does not exist).

            Jack McSlay's example can be fixed with [man]file_exists/man, possibly including a check that the file to be included is not index.php, and ScoobyDooobyD00's example can be fixed by properly using [man]isset[/man]. I suspect ScoobyDooobyD00's example is better since it can be more directly transformed to use a database later on. On the other hand, Jack McSlay's example could be a more long term solution, but at the risk of the user being able to arbitrarily include any file in the current directory.
