Feedback form in PHP

Feed back form is very important for any website point of view. Any website can have this feedback form to collect the messages from the visitors and post to any email address. Feedback form developed by HTML and then processing is done by using PHP. Any other CGI or scripting language can be used to post the message from the website to the webmaster. We will discuss PHP feedback form here. By using a feedback form or contact us form the email address need not be exposed to web robots who will pick up the email address for spamming. Visitors away from their home computer or using public computers may not able to post messages with a mailto link. This can be completely avoided by using feedback forms as all the details of the feedback form is posted to email address by using PHP. PHP email function is a built-in php function.

Let us first start with HTML to display the feedback form. You can see the contactus page of this site ( view source ) to get the html code. The detail country list is also available there.
<form method='post' action='contactusck.php'>
<table border="0" width="100%" cellspacing="0" cellpadding="0">
<tr>
<td width="50%" class='topsub' align = center COLSPAN=2>

This form is posting all the variable to another page contactusck.php and there the visitor entries are validated. You can see the only compulsory requirement for the visitor to fill the email address and other input boxes are optional. You can check the form validation page of this site to get details on how to validate a form.

Now we will process the contactusck.php page to post the details to webmaster's email address.

We will do the PHP email validation to check the user entered email address is in correct format or not

$status = "OK";
$msg="";
//error_reporting(E_ERROR | E_PARSE | E_CORE_ERROR);
if (!stristr($em,"@") OR !stristr($em,".")) {
$msg="Your email address is not correct<BR>";
$status= "NOTOK";}

We will check the flag $status to know the status of validation and if passed we will prepare the header of the email address. Then we will use the php email function to send the email. PHP email function takes four parameters.

mail("nobody@aol.com", "the subject", $message, "From: webmaster@$SERVER_NAME\nReply-To: webmaster@$SERVER_NAME\nXMailer: PHP/" . phpversion());

Here is the code we use in our site to send the details.

if($status=="OK"){// echo $query;
$headers="";
$headers4="webmaster@sitename.com"; ///// Change this address within quotes to your address ///
$headers.="Reply-to: $headers4\n";
$headers .= "From: $headers4\n";
$headers .= "Errors-to: $headers4\n";
$headers = "Content-Type: text/html; charset=iso-8859-1\n".$headers;
mail("wemaster@sitename.com,otheraddress@hotmail.com,onemore@yahoo.com","Feedback From plus2net.net","This is the feedback from plus2net.net <BR>
First Name :$fname
<BR>Last Name :$lname
<br>Email Addrss: $em<br>Phone no:$telephone<br>Address1:$ad1<br>Address2:$ad2<br>City:$city<br>
State:$state<br>Country:$country<br>Zip:$zip<BR><BR> <BR> Message Details : $dtl","$headers");
echo "<center>Thank you <br><br> We will contact you soon </center>";
}

Thats all. Our feedback form is ready.
