$_GET isn't passing in URL

godzilla74

Hi all,

Paint me confused here. I was under the impression that variables passed in an HTML <a href...> would be passed in the URL to the next page. Am I wrong?

For example, I have two pages, the first is an HTML page with 3 simple links in it:

<a href="category.php?sku=11111">By SKU#1</a>
<a href="category.php?sku=12345">By SKU#2</a>
<a href="category.php?sku=12222">By SKU#3</a>

Then, on category.php, where the posting is taking place, I have this:

<?
$sku = $_GET["sku"];
?>

<html>
<head>
<title>BLAH</title>
</head>

<body>
<p>You are Looking For SKU #: [code=php]<? echo "$sku"; ?>

</p>
</body>
</html>
[/code]

Now, everything works correctly. The SKU from the associated <A HREF> tag are placed correctly in $sku on this page. The confusing thing to me though is that they URL remains the same even after I am transferred to the .php page, which is "http://localhost/cattest.html" !!

Help me out here, but my understanding of $_GET tells me the URL should be something like "http://localhost/category.php?sku=11111",not the plain-jane URL that I am getting even after clicking the hyperlink.

Any idea why this is happening?

Thanks,
Justin

perhaps your url is being rewritten by means of mod_rewrite?

godzilla74

Good Idea, however I checked and that doesn't seem to be the issue (unless I just have no clue what I am doing ~which is always a possibility 🙂 ).

I have a .htaccess file in my web server directory that simply says:
'RewriteEngine off'. I rebooted my server and still have the same results.

Any other ideas out there?

Thx!

It could have to do with register_globals being turned off in php.ini. Note that it is turned off for a reason.

godzilla74

Man, I am seriously stumped here! That didn't work either. I am using php4.4.7, which has register_globals off by default, I turned it on for the heck of it and restarted the server. Still get nothing!

Well, make sure you turn it back off and restart.

Also, put this in your script and paste the output:

print_r($_SERVER);
print_r($_GET);

godzilla74

Ok, here is my output:

You are Looking For SKU #:

12345 

What exactly am I looking for here?  Pretty much just looks like a combination of my httpd.conf file and php.ini....?

Thanks,
Justin

The Array ( [sku] => 12345 ) would seem to indicate that the $_GET['sku'] value is set. So here's a silly question for you: are you sure short_open_tags is enabled on your host? If not, you need to use "<?php" instead of just "<?". (This will also make your code more portable.)

godzilla74

Hi NogDog, thanks for the input!

Not a silly question at all, however short_open_tag is 'on' when i check my php.ini file. The $sku variable is passing in the URL though, because going from cattest.html --> cattest.php does in fact post the $sku variable according with the hyperlink that was clicked.

It's not that I am complaining, I mean, everything seems to work fine (variable is passed in URL, it is posted correctly to the next page, etc.). It's just that I was wondering why the URL isn't changing as it should.

Thanks,
Justin

Well it looks like you need Miss. Cleo on this one! but why don't you try to use a fully qualified url in your links and see if that has any effect?

NogDog

Sorry, guess I misunderstood the question. Unfortunately, I think I'm still confused.

Your links in your original post point to cateogry.php, but then you are later talking about the URL not being what you expected at cattest.php. Is that a typo somewhere, or is there some sort of redirection going on?

godzilla74

Hey guys, thanks for the ideas. I did try to put the full URL in as the hyperlink and still got the same results.

NogDog...You are correct, the 'cattest.php' I put was a typo! I did mean category.php. Sorry!

This whole thing is just odd! Like I said, oh well, it works the way it is, I was just curious why i dont get to see the cool ?blah=blah after the link :mad: ...... user experience wise, they wont even notice the difference.

If there are any other ideas out there, I am pretty open to try anything!

Thanks All,
Justin
