Knowing the form action

Hi!

Is there a way to know if the page is:
- directly called from the browser
- called by the submit button pressed in POST mode
- called by the submit button pressed in GET mode

?

Thanks

Re: Knowing the form action

If you had a button like



You could check:

if (isset($_POST['btn'])) {
echo 'Button post.';
} elseif (isset($_GET['btn'])) {
echo 'Button get.';
} else {
echo 'Page view.';
}

mmm... I'm doing something like

if (count($_POST)> 0) {
echo 'Button post.';
} elseif (count($_GET)> 0) {
echo 'Button get.';
} else {
echo 'Page view.';
}

but if I visit

http://www.mysite.com/?submitted=false

I get "Button get." also if I didn't pressed nothing :(

Because that is how get data is sent to the server. Sever side you simply
can not tell. Why do you need to?

Re: Knowing the form action

$_SERVER['REQUEST_METHOD']

Contains which method you used to access the page

elseif (count($_GET)> 0) {
echo 'Button get.';}

if you access the url http://www.mysite.com/?submitted=false, then you
have something in your $_GET variable, that's why it displays button
get ^^

Directly meaning by typing the URL into the browser's address bar?
Yes, but it's not 100% reliable; $_SERVER['HTTP_REFERER'] should be
empty.

You can use $_SERVER['REQUEST_METHOD'], but you would do well to
remember that almost anything a browser does to access content can be
emulated by other programs.
