excluding empty fields

[cherubrock74]

I have searched the forum and cannot find anything similar so hope someone can help me solve this
I have a flash form mailing data using php and it is working great except I would like to exclude from the email all the form fields that were left empty.
here is part of the php code I am using...

<?  

$adminaddress = "[e-mail]"; 
$siteaddress ="http://www.mydomain.com"; 
$sitename = "My company name"; 
$date = date("m/d/Y H:i:s");

if ($REMOTE_ADDR == "") $ip = "no ip";
else $ip = getHostByAddr($REMOTE_ADDR);

if ($action != ""): 
mail("$adminaddress","Order", 
"Message details:\n
Name: $fname 
Date: $party_date
Delivery Date: $delivery_date
Delivery Time: $delivery_time
Number of Guests: $guests

Special Instructions:
------------------------------
$special_instructions

mail("$email","Thank you from $sitename", 
"This message is to confirm we have received the order information for: $pname\n

Best Regards,

$sitename
$siteaddress","FROM:$adminaddress");

$sendresult = "Thank you for visiting <a href = \"$siteaddress\" target = \"_blank\"><u>$sitename</u></a>. You will receive a confirmation email shortly. ";
$send_answer = "answer=";
$send_answer .= rawurlencode($sendresult);
echo "$send_answer";
endif;
?>

Of course the values are coming from the flash side but I was hoping to solve this with some code on the php to exclude the empty fields values...

Do you mean something like this?:

$body = "Message details:\n";

if ($fname!="") { $body .= "Name: $fname\n"; }
if ($party_date!="") { $body .= "Date: $fname\n"; }
if ($delivery_date!="") { $body .= "Delivery Date: $fname\n"; }
if ($delivery_time!="") { $body .= "Delivery Time: $fname\n"; }
if ($guests!="") { $body .= "Number of Guests:$fname\n"; }

$body .= "\nSpecial Instructions:\n";
$body .= "------------------------------\n";
$body .= "$special_instructions";

mail("$adminaddress","Order", "$body");

This hasn't been tested so might not be perfect but I hope it gets across the general idea 🙂 It basically builds the email body based on the fields that contain data.

Hope that helps,

empty()

Thank you for your quick replies guys. 🙂
I would like to understand more about that empty() tag suggested by Dagon.
Can you provide me an example based on the php code I posted? I would like to see it applied to one of my variables...example fname...is it possible to see it?

Your code assumes that you have register globals directive ON, which is an out-dated way to pass variables values from your form.

if you have a form with POST method, you reach the entered values based on their name="XYZ" tag in $_POST array.

Hi djjjozsi thanks for the reply...
My form is flash based and the values come from there...dont know if it makes a difference...I am willing to re-write the whole php if it will be safer and better but I need some help on where to start...
I was considering also BIOSTALL solution, seems pretty clever...
I will let you know how I solved this...maybe will help others with the same problem too

here you can see a way to check required fields, and make an error message:
