How to create a feedback form in my website?

[Binod Rai]

<?php
    $yourname = $_REQUEST['yourname'];
    $youremail = $_REQUEST['email'];
    $yourorg = $_REQUEST['yourorg'];
    $yourcomment = $_REQUEST['yourcomment'];
    $submit = $_REQUEST['submit'];
 
    if(isset($submit)) 
    {
        if($yourname ==""){
        $error = "Please fill in your name.."; }
        elseif($youremail =""){
        $error = "Invalid email address"; }
        elseif($yourcomment == ""){
        $error = "Please fill in your comment"; }
    }
    else
    {
            mail("[e-mail]","$yourname<$youremail>",$yourcomment);
            print "<link href='feedback.php'>";
    }
?>

I get the following Error. How can I overcome the following error? Please help me.

Warning: mail() [function.mail]: "sendmail_from" not set in php.ini or custom "From:" header missing in C:\xampp\htdocs\feedbackfrm.php on line 19

Your PHP installation (most likely) doesn't have a default sendmail_from (originating email address) specified in its configuration and no originating email address has been specified in the headers of your call to mail (function).

Also, if the "$yourname<$youremail>" part of your call is the intended originating email address, then the syntax of your call isn't entirely accurate, as the second (2nd) variable of a mail call should be the subject.

The correct syntax for mail is ( string $to , string $subject , string $message [, string $additional_headers [, string $additional_parameters ]] ).

Instead of:

mail("[e-mail]","$yourname<$youremai l>",$yourcomment);

Try:

mail("[e-mail]",$subject,$yourcommen t,"From: ".$yourname." <".$youremail.">");

(Where $subject represents the intended subject header of the email to be sent).

To give you an idea, for comparative purposes, this is what the call to mail() looks like as it is in the email management component of my CMS:

mail($msgto,"[".global_sitename."] ".$msgsubject,$content,"MIME-Version: 1.0\r\nContent-type: text/plain; charset=iso-8859-1\r\nFrom: ".global_mail_blackhole);

I hope this helps. :)
