PHP URL variables and if statement

http://somedomain.com/index.php?page=download

index.php:

<?php

if (!isset($_GET['page']) {
  $page = "about"; // Default page
} else {
  $page = $_GET['page'];
}

include ("/content/".$page.".php");

?>

Cheers buddy, looks good, am about to go out so will test as soon as i get back in.

Cheers, ILMV

You should put:

<?php

if (!isset($_GET['page']) {
  $page = "about"; // Default page
} else {
  $page = $_GET['page'];
}

include ("content/".$page.".php");

?>

remove the slash '/' before content!!!

val542 is correct in that most likely, your webroot is not the root of the server, so in the example code I posted, I should have left the beginning slash off. However, the code I posted is not inaccurate--it is legal code. That is, you could make the root of your server be your DocumentRoot--in which case "/content/" may be a valid path.

val542, a little more thorough reply would be more helpful.

Um, error....

Parse error: parse error, unexpected '{' in e:\domains\m\meltdownsoftware.co.uk\user\htdocs\test web\about\index.php on line 63

Line 63 of my code is arrowed below

<?php 

if (!isset($_GET['page']) {  <--------------- 
  $page = "download"; // Default page 
} else { 
  $page = $_GET['page']; 
} 

include ("content/".$page.".php"); 

?>

Any ideas?

If the error in that line is not obvious to you, I have to ask how long you've been programming. I'm not trying to be rude, but seriously, it's simply a case of unbalanced parenthesis. Change the line to this:

if (!isset($_GET['page'])) {

Sorry I posted code that was not error-free, though. :)

i need help in php
<?php
$num=2;
?>
<a href="action.php?id='.$num.'">Text to be displayed</a>

Here i m not getting $num value when i print echo $_GET;

Please help me

Here is a tiny bit of PHP that will better demonstrate the logic. Instead of a link, I used a textbox in a form so you could actually change the ID to see that the code works. Create a page named test.php like this:

<?php
$id = (isset($_GET['id']) ? $_GET['id'] : 2);
?>

ID: <?= $id ?>
<br />
<form method="GET" action="test.php">
<input type="text" name="id" size="3" value="<?= $id ?>" />
<input type="submit" />

For a short time, you can see this code in action here:

sample.php

<?php
header('location:login.php?id='.$username.'');
?>

login.php

<?php
$user=htmlspecialchars($_GET["id"]);

echo $user;
?>
