How do I know if parameter exists? I mean, I have some url, it can be with / without parameter.
...mypage.php?param=1
...mypage.php
So I need to know if url consists "param" itself (not value  )

Try this:
$query = CCGetQueryString("QueryString","");
$found = strpos(strtoupper($query),strtoupper("param"));
if ($found) {
echo "Hey! I see it!";
}
else {
echo "Nope. Not found.";
}

HI;
You should use the functions provided to you by CSS4.
1. CCGetFromGet(ParameterName, DefaultValue)
or
2. CCGetFromPost(ParameterName, DefaultValue)
e.g.
$value = CCGetFromGet("param",0);
if ($value == 0){
echo "Param Does not exist";
}
else {
echo "Param Exists, and the value is " . $value ;
}

Hi Manuel,
thank you for your replay, but it is not what I need. If you read my first post, I need to know if url consists "param" itself (not value ;) ) but CCGetFromGet or CCGetParam returns Value but not parameter itself.

Hi Gina
Try This
Let me know if it works for you.
function selfURL() {
$s = empty($_SERVER["HTTPS"]) ? ''
: ($_SERVER["HTTPS"] == "on") ? "s"
: "";
$protocol = strleft(strtolower($_SERVER["SERVER_PROTOCOL"]), "/").$s;
$port = ($_SERVER["SERVER_PORT"] == "80") ? ""
: (":".$_SERVER["SERVER_PORT"]);
return $protocol."://".$_SERVER['SERVER_NAME'].$port.$_SERVER['REQUEST_URI'];
}
function strleft($s1, $s2) {
return substr($s1, 0, strpos($s1, $s2));
}
$URL=selfURL();echo $URL;

Sorry Gena
The code I sent for you retrieves the entire URL including parmeters into a string
eg: $URL=selfURL();
now you have the complete URL in a string and can do anthing with it. Try echoing the string $URL, I'm sure that will help you.
If you know the name of the parameter just search the string
if(strpos($URL,"param"){DO HERE IT IS:} (Note probably good to use strtoupper like shown above)
If you do not know the names of the parameters you can scan thru the string
parsing between the ? and = chars or the & and = chars and you will get all the parameter names.
Sorry I thought there were plenty of string checking examples alredy posted here only the issue of getting the parameter names was missing.
Does that help?

John, thank you. This is also good idea.
but don't you think that using of CCGetQueryString is much more easy? and this is build-in function too.

My dear Gena
I my experience there are always more than one way to do anything in code. It all depends on what you are trying to do.
CCGetQueryString Certainly might work just fine in your application. I do not know. If you think it fills your needs then by all means it is better.
Take Care
