$_get is not retrieving my variable from the URL

[piscatorhominum]

my "$_get" function is not retrieving the "id" variable from the URL (".../index.php?id=1")

 

I have no clue why it isn't "getting" the variable. I don't get any error messages from the server and I've tried to echo the variable and it just won't read "id" from the URL

 

<?php
$article = $_GET['id'];
if ($article == 1) {
include 'article1.php';
}
elseif ($article == 2) {
include 'article2.php';
}
elseif ($article == 3) {
include 'article3.php';
}
elseif ($article == 4) {
include 'article4.php';
}
else {
include 'no_article.php';
}
?>

Put

<?php
echo '<pre>' . print_r($_GET,true) . '</pre>';
?>

at the start of your script and see what prints out.

or somewhat more simply

 

var_dump($_GET);

When it's done my way, the dump is formatted in a much more readable way. Try it on an array and see which produces a more readable display.

Are you testing this script off your harddrive or do you have it uploaded onto a server?

djfox: It's on my server 

 

kenrbnsn: I uploaded the code you gave me and then visited the page THAT INCLUDES THE SCRIPT and it had empty parentheses. I put those words in caps because the script is included on my website, not in the "index.php" file itself. I think this has something to do with it because when i point my browser to the actual script with the "id" variable in the URL it prints:

Array
(
    [id] => 7
)

script is included on my website

 

Maybe if you show your actual full code involved in the problem someone could directly solve this. xxxxx out any information you don't want to post, such as your domain name, but don't change any of the syntax (such as if you are using a URL to include the file http://xxxxx.com/file.php or using a file system path.)

[piscatorhominum]

You're right. I might as well. But I feel like it would be unnecessary since my "index.php" only contains:

<?php include 'http://xxx/article_fetch.php';?>

 

and I already posted the "article_fetch.php" script.

lol @PFMaBiSmAd have you seen what that links to! 

[kenrbnsn]

Don't use a URL in the include statement. Use a normal file name.

I knew using a URL was probably it.

 

When you post part of your code out of context of how it is actually being used and you tell us that 'this is my code and it is not working', but in reality that is not all your actual code that is involved in the problem, it takes a really long time to help you, in this case ~20hours.

 

When you use a URL in an include, it causes your web server to make a http request back to your web server. This invokes a separate instance/child process of your web server/php to parse the requested file. This causes several things to happen -

 

1) It takes a minimum of 100 times longer than if you used a directly file system path,

2) The included file does not inherit the variable scope of the main file (which is why you are getting the symptoms that you are),

3) You only get back the content that is output by that file, you don't get the php code and data from that file incorporated into the main file, and

4) The settings that allow this might not be enabled on any particular server configuration, so you might find your include statement not working at all (and not just the variables) if you move to a different server or someone updates/alters the configuration of your existing server.

That solved the problem. Thank you guys for the help. It is much appreciated.
