Hi I have created a form that I want results sent to my email but i want it to have required fields and make the form secure from spam. My php looks like this: Can someone help me make the fields required and secure from spam please?

You can validate your form fields using JavaScript and PHP (the PHP part is optional) before sending the mail.

The following page will give you a step by step explanation about various mail sending methods in PHP using the normal mode:

PEAR PHP extension supports a mail class which contains various utilities and you can make use of that if you need that:

For me when I've used the mail function of PHP sometimes it acted as spams and when I used the PEAR it worked for me.

i think you mean the other way around. the javascript is optional. php is mandatory. people could bypass the javascript by disabling it.

Master Script Maker is right: if validation is necessary, use javascript to make it easier but do not rely on that javascript.

$sendit = mail("my@email.co.uk", "Website contact form", $result, $headers) or die("Something went wrong");

echo "<meta http-equiv='refresh' content='0; url=thank.htm'>";
die;

?>


get rid of the html redirect, instead use


if(mail("my@email.co.uk", "Website contact form", $result, $headers))
{
// sends the user to the good page
header('thank.htm');
}
else
{
// kills the processing and prints an error
die('Could not send email');
}
