[RESOLVED] $_REQUEST

gotornot

Justa quicky about the $_REQUEST

I am collecting data either posted or egt to my script i have variables that are predefined ie name, address etc.
The data is being passed via another web server (another company) they send unique replies to questions that i ask of them for example

http://www.mysite.com/myscrip.php?name=bob&surname=Bits&1=yesplease&3=nothanks

The 1 and 3 are 2 questions asked however how owuld i collect them as theyy are not predfined?

can i do this:

$var = $_REQUEST['WHAT GOES HERE????'];

How would i solve this problem?

Many Thanks

Andy

First, I never use $REQUEST.
I use specifically $POST and $_GET, because I have learnt this is good standard.

It is possible to loop through array $REQUEST or $POST or $_GET using a foreach loop.
[man]foreach[/man]

How you will do depends on what you want to do with values:
- save them in database
- write them into a file
- just display echo values

if(isset($_GET)){
    foreach($_GET as $key=>$value){
        echo $key.' = '.$value. '<br />';
    }
}

if (isset($_GET)) {
	foreach($_GET as $key=>$value)

isset() check is $GET is set at all, and if it is set, it will be an array. At least as far as PHP's automatic handling of $GET goes, and the same applies to $_POST.

foreach goes through the entire array, and on the form as $key => $value, you always have both the key and the value. $value could be of course be an empty string. If you want to assign a default value instead of an empty string, you could

if ($value == '')
	$value = 'default value';

But if you by missing value rather mean that you always need some elements in the array but have no guarantee that they are there, you could

$always = array('key1' = 'value1', 'key2', 'value2');
foreach ($always as $k => $v) {
	if (empty($_GET[$k]))
		$_GET[$k] = $v;
}
# deal with $_GET as shown before
foreach ($_GET as $k => $v)

As for overwriting data in the DB or not, that depends entirely on the query you execute and what the table looks like.
