[FX.php List] HTTPS Post

[Leo R. Lundgren]

POSTing form data to the server via HTTPS instead of the usual HTTP  
doesn't depend on PHP in any way.

What you need to do is to make sure that in your form, you have the  
action="" set to an url that is indeed a HTTPS url, such as  
action="https://example.com/formhandler.php" instead of  
action="http://example.com/formhandler.php".
If you are using relative urls such as action="formhandler.php", you  
will need to make sure that the user have already loaded the current  
page (the one with the form) from the server via HTTPS, for example  
so that their address bar says "https://example.com/myform.php"  
instead of "http://example.com/myform.php". If it does, then the  
relative action of the form will simply use HTTPS since this is the  
current "basis" for the page and nothing else is specified for the  
protocol.

Regarding the PHP side, there's nothing special to do if you just  
want to grab the input, you access the data via the usual $_POST  
variable (see the manual under "Variables" for more information).
However, if you first want to make sure that the user posted the  
stuff using HTTPS you can check the variable $_SERVER['HTTPS'] - if  
it is set (and I believe it also contains the value "on" if that is  
the case, at least in Apache environments) this should indicate that  
the protocol used for the connection is https.

Apart from the above, you/the administrator of the webserver need to  
configure it so that HTTPS is enabled for the domain/virtual host  
that your site resides in.

Hope this helps.
