I'm having a problem with a php form. The problem is when I submit the form, I would like for it to clear the data entered after it sends the email, and go to another page that says, "Information Received" and then automatically go back to the form page. When it goes back to the form page, if somebody refreshes the page, it wont submit the data again. Can this be done? If so, how because I've tried everything? Thanks
Here's my code -
<html>
<head>
<script language="JavaScript">
function checkForm()
{
var cname, cemail, cphone, ccomments;
with(window.document.msgform)
{
cname = sname;
cemail = email;
cphone = phone;
ccomments = comments;
}
if(trim(cname.value) == '')
{
alert('Please enter your name');
cname.focus();
return false;
}
else if(trim(cemail.value) == '')
{
alert('Please enter your email');
cemail.focus();
return false;
}
else if(!isEmail(trim(cemail.value)))
{
alert('Email address is not valid');
cemail.focus();
return false;
}
else if(trim(cphone.value) == '')
{
alert('Please enter message subject');
cphone.focus();
return false;
}
else if(trim(ccomments.value) == '')
{
alert('Please enter your message');
ccomments.focus();
return false;
}
else
{
cname.value = trim(cname.value);
cemail.value = trim(cemail.value);
cphone.value = trim(cphone.value);
ccomments.value = trim(ccomments.value);
return true;
}
}
/*

function trim(str)
{
return str.replace(/^\s+|\s+$/g,'');
}
/*

function isEmail(str)
