Only send email with conditions

[kml2katz]

I have a section of code in a php page that I need help with. Basically, what I want to do is to only send an email if a certain value(s) are in a field.

// send the email
$to = $CompUserName; 
$from = "[e-mail]"; 
$subject = "confirmation"; 
$headers  = "From: $from\r\n"; 
$headers .= "Content-type: text/html\r\n"; 
mail($to, $subject, $message, $headers); 

The field that it needs to check is $transaction_subject. It should send the email if the value of that field is one, two or three. The field is in the same program as the sending of the email. This is how it is written in the program:

$order_data['transaction_subject'] = $transaction_subject;

Can someone show me how to do this?

Pseudocode 101,

if (condition) {
 //do somthing
}

so in your case,

if (in_array($transaction_subject, array(1,2,3))) {
  mail(...); //if transaction_subject does equal 1,2 or 3, send email. 
} else {
  die(); //or whatever method you want to handle the error
}

edit: that's not how I would do it, I would define a var like $error to = 0, then proceed to do these if statment checking fields aren't empty or invalid char's etc, if they are, make $error 1 or a message, than at the bottom have it only send the email if $error = 0 or else show an error message about what the user messed up on

I don't know if I put your code in the right place or not. Also, do I need to name the array. The array that the $transaction_subject is in is $order_data. Can you take a look at my code and see if it is correct?

// send the email
$to = $CompUserName; 
$from = "[e-mail]"; 
$subject = "confirmation"; 
$headers  = "From: $from\r\n"; 
$headers .= "Content-type: text/html\r\n"; 

//if (in_array($transaction_subject, array(1,2,3))) { 
//  mail(...); //if transaction_subject does equal 1,2 or 3, send email. 
if (in_array ($transaction_subject, array("Split Specimen Test","Drug Test","Employee")))
mail($to, $subject, $message, $headers); 

} else { 
  die(); //or whatever method you want to handle the error 
}
