"?value" instead of "?variable=valu

Anon

Ok,
Usually a variable is sent through a URL like this:
script.php?variable=value

I have seen scripts on the net that only need to send one variable and just send the value:
script.php?value

How do we receive this value? Is it put into a variable?

I am told in a previous message that we use isset() but i dont know what i am looking for. Which variable is set? Have i got it wrong above? Is it that when you do:
script.php?value
you actually just set the variable to "" like this
script.php?variable
?
I dont know. Could someone see if they can help me out. Give me example code of how to get this variable?

Thanks in advance

file.php?value

$allTheVars = array_keys($_GET);

$myVar = $allTheVars[0];

so, $myVar is going to be your set variable in the URL.

Never used it this way. I always do script.php?var1=1&var2=2&var3=3

And then, on the next page, check for:

$var1,$var2 and $var3,

$GET["var1"],$GET["var2"] and $_GET["var3"]

$HTTP_GET_VARS["var1"], $HTTP_GET_VARS["var2"] and $HTTP_GET_VARS["var3"]

If you're afraid that someone can enter the value in the URL, you can always set a FORM and use POST instead. Then, on the next page, use this:

if($REQUEST_METHOD != "POST"){
you_think_you_are_clever_huh();
}else{
you_are_a_good_guy();
}

Of course these functions do not exist.
Hope it helps

Thanks.
Its not that i dont want people to send variables, i just think it looks tidier.

I like your idea as well fLIPIS! Looks like i got a bonus.

Many thanks to the both of you.

:-) You're very welcome, mate. With POST, it looks even tidier, because nothing more than the script filename appears in the URL box.

I have done this small script...

<?
$var = array_keys($_GET);
$action = $var[0];
echo"Action = ${action}";
?>

But it doesnt find the value.
You can get the script in action at..

just add a value to the end.

$_GET is only available to PHP 4.1.2. Sorry i didn't say it. Use $HTTP_GET_VARS instead.

Sorry, mate

This is my new script...

<?
$var = array_keys($HTTP_GET_VARS);
$action = $var[0];
echo"Action = ${action}";
?>

Again viewable at...

Thanks

Try $action instead of ${action}

This is WEIRD

Kepp trying.

I'm puzzled as hell, mate. No idea why this doesn't work. My only advice is to use $variable, but that's not clean or secure.

Hi Skripty,

I have another method of making clean looking URL's that has the added benefit of making them search engine friendly:

<?php
$url_array = explode("/",$REQUEST_URI);
$variable1 = $url_array[2];
$variable2 = $url_array[3];
?>

Include this script at the top of all pages

Then instead of:

www.yourdomain.com/page1.php?variable1=1&variable2=2

you can call it as:

www.yourdomain.com/page1/1/2

Give it a go, it works for me

Cool that is good!
You could also make it compatible no matter how many slashes there are before you get to the values.
At the moment you have to set at what stage of the array it is but if you do the following it will avoid that...

<?php
$url_array = explode("?",$REQUEST_URI);
$value_array = explode("/",$url_array[1]);
$variable1 = $value_array[0];
$variable2 = $url_array[1];
?>

Is that any good?
You could use it as a PHP include file. Save you putting all that at the top of each script.
Thanks
