$file = fread($fp, $upload_size);
$file = chunk_split(base64_encode($file));
$num = md5(time());
//Normal headers
$headers = "From: Info Mail<Info#example.com>\r\n";
$headers .= "MIME-Version: 1.0\r\n";
$headers .= "Content-Type: multipart/mixed; ";
$headers .= "boundary=".$num."\r\n";
$headers .= "--$num\r\n";
// This two steps to help avoid spam
$headers .= "Message-ID: <".gettimeofday()." TheSystem#".$_SERVER['SERVER_NAME'].">\r\n";
$headers .= "X-Mailer: PHP v".phpversion()."\r\n";
// With message

$headers .= "Content-Transfer-Encoding: 8bit\r\n";
$headers .= "".$message."\n";
$headers .= "--".$num."\n";
// Attachment headers
$headers .= "Content-Type:".$upload_type." ";
$headers .= "name=\"".$upload_name."\"r\n";
$headers .= "Content-Transfer-Encoding: base64\r\n";
$headers .= "Content-Disposition: attachment; ";
$headers .= "filename=\"".$upload_name."\"\r\n\n";

$headers .= "--".$num."--";
// SEND MAIL
mail($to, $subject, $message, $headers);
fclose($fp);
echo '<font style="color:#333333">Mail sent please check inbox and spam both <br /></font>';
}
}
?>
//HTML code for form details and adding attachment..
<form id="attach" name="attach" method="post" action="<?php echo $_SERVER["PHP_SELF"]; ?>" enctype="multipart/form-data">
//Html code for mail details
</form>
I am getting "Warning: mail() [function.mail]: Bad parameters to mail() function, mail not sent...." and also it is showing the "Mail sent please check inbox and spam both ".. what's the problem ?
Help me to fix this problem...

Answer 1

You're passing bad data to the mail function. Head over to http://php.net/manual/en/function.mail.php and read the documentation that tells you how to use it.
Also note that it returns a boolean value that tells you whether your attempt to mail was successful so at the very least:
....
$success = mail(...);
if ($success) {
echo "<p>mail sent</p>";
} else {
echo "<p>error: mail was not sent.</p>";
}
so that your code isn't lying about whether it sent the mail or not.
As for your massive amount of data: comment it all off. Then progressive uncomment bits until it breaks. You have now found the problem and can solve it by looking at what you're giving the mail() function that it doesn't like.
