index.php?page=1

[gamehead200]

Hey everyone!

Is there a way to make it so that when you click on a link, it will send you to whatever page name is in the link?

What I mean is, how do people make pages like index.php?page=1 ? I've been wondering for such a long time!

[sde]

well a variable in the url is just that, a variable. what you do with that information is up to you. here is a little example of how you can changed content based on the querystring page=1

PHP Code:

<?
if($page == 1){
  echo "this is page 1";
}elseif($page == 2){
  echo "this is page 2";
}else{
  echo "invalid page";
}
?>

if you have more specific questions, feel free to ask.

Something like this?

PHP Code:

<?php

$p = $_GET['p'];
$p = "css/$p.txt";

if( file_exists($p) )
{
    include($p);
}
else
{
    echo('AN ERROR HAS OCCURRED!');
}

?>

Something like that, but I'd run the var through basename() first for paranoia.

i thought about the include thing too, .. but it seemed silly to put the filename in the query string instead of just calling that file itself.

also, great point idx.

Wait, how can I put in a default file to open when I open index.php with no variable in the URL?

[sde]

in my example, the default would be the 'else' area.

OK, this code is really starting to piss me off:

PHP Code:

<?php

$p = $_GET['p'];
$page = "pages/$p.txt";

if( !isset($page) )
    $page = "pages/Home.txt";

if( file_exists($page) )
    include "$page";
else
    print("<tr><td class=\"base\" colspan=\"2\">AN ERROR HAS OCCURRED!</td></tr>");

?>

Everytime I run index.php without a variable, the default page outputs the error message in there... Shouldn't this work? :/

[sde]

well with that code, $page will always have a value because you are assigning it "pages/.txt" even if there is no $_GET['p'] variable defined.

try this:

PHP Code:

<?php

$p = $_GET['p'];


if( !isset($p) ){
  $page = "pages/Home.txt";
}else{
  $page = "pages/$p.txt";
}

if( file_exists($page) ){
  include($page);
}else{
  print("<tr><td class=\"base\" colspan=\"2\">AN ERROR HAS OCCURRED!</td></tr>");
}

?>

Yeah, I figured that out just before you replied... This also works:

PHP Code:

<?php

$p = $_GET['p'];
$page = "pages/$p.txt";

if( !$p) )
  $page = "pages/Home.txt";

if( file_exists($page) ){
  include "$page";
}else{
  print("<tr><td class=\"base\" colspan=\"2\">AN ERROR HAS OCCURRED!</td></tr>");
}

?>

[sde]

if you really wanna have fun, use the ternary operator

PHP Code:

<?
$page = "pages/".(($_GET['p'])?$_GET['p']:"Home").".txt";
if( file_exists($page) ){
  include "$page";
}else{
  print("<tr><td class=\"base\" colspan=\"2\">AN ERROR HAS OCCURRED!</td></tr>");
}
?>

Here's the final product... Let me know what you think:
