Question

I am trying to create a simple property in a php file that displays information about a dog. I can get the base code to work, but when I implement a new property It wont update. I've been staring at my code for hours now and can't figure out what i've done wrong. Again, the only function that I can't get working is the Gender Property

File Dog:

class Dog
{
// ----------------------------------------- Properties -----------------------------------------
private $dog_weight = 0;
private $dog_breed = "no breed";
private $dog_color = "no color";
private $dog_name = "no name";
private $dog_gender = "none";

// ---------------------------------- Set Methods ----------------------------------------------
function set_dog_name($value)
{
   $error_message = TRUE;
   (ctype_alpha($value) && strlen($value) <= 20) ? $this->dog_name = $value : $error_message = FALSE;
   return $error_message;
}

function set_dog_weight($value)
{
   $error_message = TRUE;
   (ctype_digit($value) && ($value > 0 && $value <= 120)) ? $this->dog_weight = $value : $error_message = FALSE;
   return $error_message;
}

function set_dog_breed($value)
{
   $error_message = TRUE;
   (ctype_alpha($value) && strlen($value) <= 35) ? $this->dog_breed = $value : $error_message = FALSE;
   return $error_message;
}

function set_dog_color($value)
{
   $error_message = TRUE;
   (ctype_alpha($value) && strlen($value) <= 15) ? $this->dog_color = $value : $error_message = FALSE;
   return $error_message;
}
function set_dog_gender($value)
{
   $error_message = TRUE;
   (ctype_alpha($value) && strlen($value >= 4 && $value <=6)) ? $this->dog_gender = $value : $error_message = FALSE;
   return $error_message;
}

function get_properties()
{
   return "$this->dog_weight,$this->dog_breed,$this->dog_color,$this->dog_gender";
}
}
?>

File Lab:

require_once("dog.php");
$lab = new Dog;
// ------------------------------Set Properties--------------------------
   $dog_error_message = $lab->set_dog_name('Fred');
       print $dog_error_message == TRUE ? 'Name update successful
': 'Name update not successful
';
   $dog_error_message = $lab->set_dog_weight(50);
       print $dog_error_message == TRUE ? 'Weight update successful
' : 'Weight update not successful
';
   $dog_error_message = $lab->set_dog_breed('Lab');
       print $dog_error_message == TRUE ? 'Breed update successful
' : 'Breed update not successful
';
   $dog_error_message = $lab->set_dog_color('Yellow');
       print $dog_error_message == TRUE ? 'Color update successful
' : 'Color update not successful
';
   $dog_error_message = $lab->set_dog_gender('Male');
       print $dog_error_message == TRUE ? 'Gender update successful
' : 'Gender update not successful
';
//-----------------------------Get Properties---------------------------
   $dog_properties = $lab->get_properties();
       list($dog_weight, $dog_breed, $dog_color, $dog_gender) = explode(',', $dog_properties);
       print "Dog weight is $dog_weight. Dog breed is $dog_breed. Dog color is $dog_color. Dog Gender is $dog_gender";
?>

I have rectified the problem and highlighted

<?php
class Dog
{
// ----------------------------------------- Properties -----------------------------------------
private $dog_weight = 0;
private $dog_breed = "no breed";
private $dog_color = "no color";
private $dog_name = "no name";
private $dog_gender = "none";
// ---------------------------------- Set Methods ----------------------------------------------
function set_dog_name($value)
{
$error_message = TRUE;
(ctype_alpha($value) && strlen($value) <= 20) ? $this->dog_name = $value : $error_message = FALSE;
return $error_message;
}
function set_dog_weight($value)
{
$error_message = TRUE;
(ctype_digit($value) && ($value > 0 && $value <= 120)) ? $this->dog_weight = $value : $error_message = FALSE;
return $error_message;
}
function set_dog_breed($value)
{
$error_message = TRUE;
(ctype_alpha($value) && strlen($value) <= 35) ? $this->dog_breed = $value : $error_message = FALSE;
return $error_message;
}
function set_dog_color($value)
{
$error_message = TRUE;
(ctype_alpha($value) && strlen($value) <= 15) ? $this->dog_color = $value : $error_message = FALSE;
return $error_message;
}
function set_dog_gender($value)
{
$error_message = TRUE;
(ctype_alpha($value) && strlen($value) >= 4 && strlen($value) <=6) ? $this->dog_gender = $value : $error_message = FALSE;
return $error_message;
}
function get_properties()
{
return "$this->dog_weight,$this->dog_breed,$this->dog_color,$this->dog_gender";
}
}
?>
Output
