HTML - Online Forms

Can someone please explain how forms work please.

I know how to set them up and send them to another file to be processed. How do i set up the file to process it?

Example:
My form:
Quote:
<form action="http://www.music-web.org/webmail2.php" method="post" name="webMailLogin">

<input type="hidden" name="submitted" value="y" />
<table border="0" cellpadding="0" cellspacing="0" width="100%" bgcolor="#FFFFFF">
<tr>
<td colspan="2"><img src="http://music-web.org/images/clearpixel.gif" width="1" height="12"></td>
</tr>
<tr>
<td class="black12" align="right"><b>Login:&nbsp;</b></td>
<td class="QuickDomainCheck"><input type="text" tabIndex="1" name=" login_name " size="20" value=""></td>
</tr>
<tr>
<td colspan="2"><img src="http://music-web.org/images/clearpixel.gif" width="1" height="12"></td>
</tr>
<tr>
<td class="black12" align="right"><b>Password:&nbsp;</b></td>
<td class="QuickDomainCheck"><input type="Password" tabIndex="2" name=" passwd " size="20" value=""> <input type="image" src="http://www.music-web.org/images/webmail/login.gif" align="absbottom" value=" Login " tabIndex="3" ></td>

</tr>
<tr>
<td colspan="2" align="left">
<BR><BR><div class="text" style=" color:000000; font-family:arial; font-size:10px; padding-left:124; padding-top:5">Login using your email address and password.</div>
</td>
<td class="black10"><br><br></td>
</tr>

</table>
</form>
It gets sent to:
Quote:
<script language="JavaScript" TYPE="text/javascript">
function submitMe()
{

loginName = ' I need the value of the form in here ';


//find @
atPos = loginName.indexOf("@");

//check >=1
if (atPos >= 1 )
{

//get the domain name length
domainLength = (loginName.length +1)

//get the domain name
domain = loginName.substring(atPos +1, domainLength );

//get the username
user = loginName.substring(0,atPos);

//set up the username to post to the mail form
document.implogin.loginuser.value = loginName;
document.implogin.imapuser.value = user;
document.implogin.pass.value = 'I need the value of the form in here ';
document.implogin.maildomain.value = domain ;
document.implogin.maildomain.realm = domain;
document.implogin.url.value = 'http://webmail.'+ domain + '/horde/login.php';document.implogin.action = 'http://webmail.'+ domain + '/horde/OWH_Logout.php';
document.implogin.submit();

}
else
{
alert('Please enter in your full email ie. someone@yourdomain.com');
}


}

I hope this isn't too confusing and someone can help.

I am a beginner! (I thought I would warn you.) Can someone here please tell me how to do the code for being able to see how many viewers are online at a particular site. For instance so all shoppers can see how many people are shopping in that store at the same time? I hope that makes sense. Many thanks in advance!!

A client needs to edit one page of their site remotely using a browser. I'm not sure how to proceed. Do they need a page with form fields that are password protected so only they can provide content? Is there another way to edit wysiwyg text online without using a separate application? Any help would be appreciated.

Ok so I am trying to create an online registry where people with rare diseases can register their name what disease they have where they live and it will email them of those around them with the same thing. Can someone please tell me how to do this or where i can go to learn how to do this.

Thanks
