php lists and checkboxes

[HMC]

Thanks for all your previous replies to last posting - appreciated. However, just one thing. What do you do with lists and checkboxes? Can you use them at the beginning with like the following: What do you put in to make sure it returns all the options and shows which ones are checked/chosen?

$name=$_POST['name'];
checkOK($name);
$email=$_POST['email'];
checkOK($email);
$comments=$_POST['company'];
checkOK($company);

Regards

I'm not sure I understand what you're asking about with checkboxes? It looks like you're working with textboxes?

However if you want to see if a checkbox is checked you would use isset().

$checkbox = (isset($_POST['checkboxname']) ? "checked" : "not checked";

Also, what is in your checkOk() function?

Hi flann,
thanks for reply. So far I have the below
but then after this (on the html form) there are several items to choose which can be either chosen by a 'list' option or by 'checkboxes' and I am not sure where this should be on the php code. If it helps the html. form is separate to the php code page.

<?php
function checkOK($field)
{
if (eregi("\r",$field) || eregi("\n",$field)){
die("Invalid Input!");
}
}
$name=$_POST['name'];
checkOK($name);
$email=$_POST['email'];
checkOK($email);
$comments=$_POST['company'];
checkOK($company);
$comments=$_POST['address'];
checkOK($address);
$comments=$_POST['telno'];
checkOK($telno);
$comments=$_POST['message'];
checkOK($message);
$to="EMAIL REMOVED - Send PM to This User Instead";
$message="$name just filled in your comments form. They said:\n$message\n\nTheir e-mail address was: $email";
if(mail($to,"Comments From Your Site",$message,"From: $email\n")) {
echo "Thank you for your enquiry, we will contact you shortly.";
} else {
echo "There was a problem sending the mail. Please check that you filled in the form correctly.";
}
   if ($_SERVER['REQUEST_METHOD'] != 'POST'){
      $me = $_SERVER['PHP_SELF'];
} else {
      error_reporting(0);
   
   if(isset($_POST['submit'])) { 
   mail($to,$subject,$body,$headers);
   $to = ‘EMAIL REMOVED - Send PM to This User Instead';
      $address = stripslashes($_POST['address']);
   $subject = "contact message";
      $from = stripslashes($_POST['name']);
      $msg = "Message from: $from\n\n".stripslashes($_POST['message']);
     
     foreach($_POST ['check'] as $value){
     $check_msg = "Checked: $value\n";
     }
     $body = "From:$name_field\n Email:$email_field\n message:\n$check_msg";

What I need to know is where and how do I place the code for the lists/checkboxes that people choose within the form.
i.e., would it be

print_r ($_POST [checkbox']);
Array
(
[checkbox] = Array
        (
     (0)= > checkboxname
     (1)= > checkboxname2
     )
)

How are lists done? or is the above incorrect? Many thanks hope it makes sense.
