getting a returned value from a function

[jrough]

I have this addAddress function call (see function below). The address value gets passed in, but I need to get the $htmlmessage out from the function which isn't currently being returned because I need to check for a 620 error code.

$map->addAddress($value);

How do I get the $htmlmessage parameter from the addAddress function? There is an $htmlmessage for invalid points and well as validpoints?
Would it be:
$htmlMsg-> invalidpoints[$htmlmessage]

Or do I need to add a return $htmlmessage from the function before the last parenthesis? In that case, since I am already calling the $map ->addAddress($value) to input the address, how can I call it the second time to get the returned value? I think I should check the invalidpoints and the validpoints $htmlmessage.

thanks,

function addAddress($address,$htmlMessage=null){
if (!is_string($address)){
die("All Addresses must be passed as a string");
}

$addressData = file_get_contents($apiURL.urlencode($address));

$results = $this->xml2array($addressData);

if (empty($results['ResultSet']['Result']['Address'])){
$pointer = count($this->invalidPoints);
$this->invalidPoints[$pointer]['lat']= $results['ResultSet']['Result']['Latitude'];
$this->invalidPoints[$pointer]['long']= $results['ResultSet']['Result']['Longitude'];
$this->invalidPoints[$pointer]['passedAddress'] = $address;
$this->invalidPoints[$pointer]['htmlMessage'] = $htmlMessage;
}else{
$pointer = count($this->validPoints);
$this->validPoints[$pointer]['lat']= $results['ResultSet']['Result']['Latitude'];
$this->validPoints[$pointer]['long']= $results['ResultSet']['Result']['Longitude'];
$this->validPoints[$pointer]['passedAddress'] = $address;
$this->validPoints[$pointer]['htmlMessage'] = $htmlMessage;
}

}

At first glance I would say either just add a return $htmlMessage; to the end of the function, or else return something to indicate that it was "valid" or "invalid" (boolean true/false?) and then let the client code grab it from the object's $validPoints or $invalidPoints array variable as applicable.

Okay, I'm learning oo programming. Would I define the boolean at the beginning see below $valid_flat?Then set that flag in the if/then? Is this what you mean by call it from the client?
thanks,

if (this-> $valid_flag = 1){
$htmlmessage = $this->invalidPoints['htmlmessage'];
}else{
$htmlmessage = $this->validPoints['htmlmessage'];
}

----addAddress function-----------
function addAddress($address,$htmlMessage=null){
if (!is_string($address)){
die("All Addresses must be passed as a string");
}

$valid_flag;

$addressData = file_get_contents($apiURL.urlencode($address));

                                                                                                      $results = $this->xml2array($addressData);

if (empty($results['ResultSet']['Result']['Address'])){
    $pointer = count($this->invalidPoints);
    $this->invalidPoints[$pointer]['lat']= $results['ResultSet']['Result']['Latitude'];
    $this->invalidPoints[$pointer]['long']= $results['ResultSet']['Result']['Longitude'];
    $this->invalidPoints[$pointer]['passedAddress'] = $address;
    $this->invalidPoints[$pointer]['htmlMessage'] = $htmlMessage;
    $this->$valid_flag = 1;
  }else{
    $pointer = count($this->validPoints);
    $this->validPoints[$pointer]['lat']= $results['ResultSet']['Result']['Latitude'];
    $this->validPoints[$pointer]['long']= $results['ResultSet']['Result']['Longitude'];
    $this->validPoints[$pointer]['passedAddress'] = $address;
    $this->validPoints[$pointer]['htmlMessage'] = $htmlMessage;
    $this->valid_flag = 0;
}

}

By "client" in this case I meant whatever application code is using this object (as opposed to "client" meaning the web browser).

I see that you have a valid_flag variable, so if you have the function return the value of $pointer, then you could get the data via something like:

class YourClass
{
   // . . .

   function addAddress($address,$htmlMessage=null) {
      // blah blah blah...
      return $pointer;
   }
}

// client code:

$test = new YourClass();
$ptr = $test->addAddress($foo, $bar);
if($test->valid_flag) {
   $html = $test->validPoints[$ptr]['htmlMessage'];
}
else {
   $html = $test->invalidPoints[$ptr]['htmlMessage'];
}

This assumes that the $validPoints, $invalidPoints, and $valid_flag class variables are public (or else otherwise accessible via "getter" methods of one sort or another).
