retrieving variables from forms

michaewlewis

How can I retrieve all of the variables from a form at once? And then after that, remove the slashes?

Currently I have a long list of each variable name, such as:
$var1 = $REQUEST["var1"];
$var2 = $REQUEST["var2"];
et. al.

What do you mean by that?

Why do you need to remove slashes? The old magic_quotes_gpc setting in php.ini should be set to Off.

What do you mean by that?

I've got about a dozen things that I'm passing from a form in file.html to file.php.
Rather than makeing a $_REQUEST for each variable, I'd like to know if I can just do one thing so that if I end up expanding the program in the future, I don't have to write a bunch more requests.

it's not turned off. I'll turn it off. it's off. thanks. why would it be turned on by default in xampp?

so you just want to move the $request['vars'] into $vars?

	foreach($_REQUEST as $key =>$value){
		$$key=$value;
	}

I think this should do the trick

So does [man]extract/man, except with extract() you can add a prefix to the incomming variables... that way you can at least avoid variable collsion.

Then again, does it matter? If you add another field to your form, don't you have to add a bit more code to your PHP script to handle this new field? I know this depends on the application, but I just thought I'd ask...

maxpup979's example could be modified to do that as well, and even to perform some input validation.

That is what I find so strange about "retrieve all of the variables from a form at once". In the end, you have to handle the incoming data, and different data have different requirements.

I'm just trying to avoid one big list of variables are the beginning of my code. That's all. It's not really critical that I find anything, just thought it would be easier. thanks
