[RESOLVED] Don't validate if field is empty

NevadaSam

On an Email form I am learning to program I don't want the script to run the a function if the the CC or BCC fields are empty. I tried both isset($GET) and empty($GET) and it still runs through the function. When it does not find an "@" or a "." it returns false, does the echo and halts.

The problem must be in the else if statement, because if the 'cc' field on the html form is null it should never go to the function.

I have only posted part of my code below. If you need to see the complete HTML code and all of the PHP file I can post them. The function also validates other addresses.

function validateRecipients($Addresses) { 
   $Address = explode(",", $Addresses); 
      $RetValue = true; 
      foreach ($Address as $Email) { 
      if (strpos($Email, '@') !== FALSE && strpos($Email, '.') !== FALSE) 
         $RetValue = true; 
      else { 
         $RetValue = false; 
         break; 
      } 
   } 
   return $RetValue; 
}

else if (isset($_GET['cc']) && validateRecipients($CC) == false) 
   echo "something";

isset() still returns true, if it is passed through.. but empty (as you might want it to be empty, but specified empty)

So instead, maybe..

if( $_GET['cc'] != null ) {

}

// or a length count, such as..

if( strlen($_GET['cc']) > 0 ) {

}

benbox

also, maybe you need the $_GET on this..

if( validateRecipients($_GET['CC']) == false) ) {

}

After working on this for a couple of days I have came up with:

else if (!empty($_GET['cc']) && validateRecipients($CC) == false)
	echo "stuff";

which seems to work. I will study this more as I get farther into php. What the script is suppose to do is: Not validateRecipents if 'cc' has no data, and if there is somethng in the text field then it checks for an @ and a . which ever email address must have.

I know this is very basic to all of you, but I am very, very new at this. I look forward to helping others someday.

Problem Solved!
