need to know how to get parameters

starfox

I am a complete newbbie on PHP and i would like to know how could i pass parameters to a php variable, from a text box.

What i am trying to do is to get the user name and password that the user will type on different text boxes and then pass that data as parameters to two different variables.

I would also like to know if there is a way for me to see if the user is already logged on so that I can decide wether to send the user to the login page or straight into the members page.

Thanx for all your help

using

$var = $_POST['textareaname'];

on the page that iscalled by the form action

$POST['var'] works if you sent the data with post method, if you have something like this:
<form action="POST">
If you use
<form method="GET">
than you should use $GET['var']
Or you can simply use $_REQUEST['var']

In order to see if the user is logged on or not you should use PHP sessions.
Register a session for that user if he is registered (using $_SESSION) than check if you have that session.

Eddited because I wirte action instead method on this form🙂

Actually, what danyprundus was referring to is the method, not action.

The action attribute determines which script (i.e. PHP page) will process the form, while the method determines by what method the form data will be passed.

method="get" is default.
