No recipient addresses found in header

[brady822]

Okay My Code works, but.... If nobody enters data into a required field it sends the form and on my HTML page... the PHP reply reads "No recipient addresses found in header"

Now I know this makes sense... Something has to be in the header info but what?

Also, why is it sending the form without the required fields filled.

Here is my CODE!

<?php
$firstName=trim($_POST['firstName']);
$address=trim($_POST['address']);
$city=trim($_POST['city']);
$zip=trim($_POST['zip']);
$phone=trim($_POST['phone']);
$cphone=trim($_POST['cphone']);
$email=trim($_POST['email']);
$contact=trim($_POST['contact']);
$priority=trim($_POST['priority']);
$within=trim($_POST['within']);
$when=trim($_POST['when']);
$source=trim($_POST['source']);
$comments=trim($_POST['comments']);

//---------VALIDATION-------->
if($firstName){//----> CHECK input
}
else{
$error.="Please, go back and fill input your full name<br>\n";//----> ERROR if no input
}
if($phone){//----> CHECK input
}
else{
$error.="Please, go back and input your home phone number, with area code<br>\n";//----> ERROR if no input
}
if($email){//----> CHECK input
}
else{
$error.="Please, go back and fill in you email address<br>\n";//----> ERROR if no input
}
if($comments){//----> CHECK input
}
else{
$error.="Please, go back and fill out the direct source if N/A, please enter N/A<br>\n";//----> ERROR if no input
}
//-------->ERROR FREE??
if($error=="Please Resubmit the form and please complete the whole form."){
echo "Thank you for inquiring about our FREE ESTIMATE! A receipt of your submission will be e-mailed to you almost immediately.";
}
//----------------------------------
$mailContent="--------CONTACT--------\n"
."Full Name: ".$firstName."\n"
."Address: ".$address."\n"
."City: ".$city."\n"
."State: ".$state."\n"
."Zipcode: ".$zip."\n"
."Home Phone: ".$phone."\n"
."Mobile Phone: ".$cphone."\n"
."E-mail: ".$email."\n"
."Contact via: ".$contact."\n"
."Interested in: ".$priority."\n"
."Starting the project: ".$within."\n"
."QRG can contact me: ".$when."\n"
."How did you hear about us: ".$source."\n"
."Comments: ".$comments."\n";
//----------------------------------
$toAddress="[e-mail]";
$subject="Long Form Free Estimate";
$recipientSubject="Free Estimate Contact Form";
$receiptMessage = "Thank you ".$firstName." for inquiring about QRG's FREE ESTIMATE!\n\n\nHere is what you submitted to us:\n\n"
."--------CONTACT--------\n"
."Full Name: ".$firstName."\n"
."Address: ".$address."\n"
."City: ".$city."\n"

."Interested in: ".$priority."\n"
."Starting the project: ".$within."\n"
."QRG can contact me: ".$when."\n"
."How did you hear about us: ".$source."\n"
."Comments: ".$comments."\n";
//----------------------------------
mail($email, $subject, $receiptMessage,"From:$toAddress");
//----------------------------------
mail($toAddress,$recipientSubject,$mailContent,"From:$email");
//--->echo $mailContent;
?>

Well, if $email is false you tack a string on the end of $error. When it comes to checking the recipient's address, that is the entire extent of your error handling. You only use the value of $error once, to output a message if $error happens to have a certain specific value.

Regardless of what $error may be, you then go on to compose and attempt to send email messages.

You really need to go back and think logically about what exactly you're trying to do.
