Question

I am trying to create a custom class and have an array of those objects and I can’t seem to get it to work. Here is my code:

class NavigationItem
{


private $_filename;
private $_linkname;

public function __construct($filename, $linkname)
{
    parent::__construct();

    $this->_filename = $filename;
    $this->_linkname = $linkname;
}

public function getFilename()
{
    return $_filename;  
}

public function getLinkname()
{
    return $_linkname;  
}
}

$navInfo = array();

$size = array_push($navInfo, new NavigationItem("index.php","HOME"),
                                  new NavigationItem("about.php","ABOUT"),
                                  new NavigationItem("coaches.php","STAFF"),
                                  new NavigationItem("summer.php","SUMMER 2011"),
                                  new NavigationItem("fall.php","FALL 2011"),
                                  new NavigationItem("history.php","HISTORY"),
                                  new NavigationItem("contact.php","CONTACT"));

echo "<table>";
echo "<tr>";
echo "<td colspan=\"7\" height=\"125px\"><img src=\"images/banner_blue_skinny.jpg\" alt=\"\" /></td>";
echo "</tr>";
echo "<tr>";

for($i=0; $i<$size; $i++)
{
echo "<td class=\"linkCell\"><a class=\"navigation\" href=\"" . $navInfo[$i]->getFilename() . "\">" . $navInfo[$i]->getLinkname() . "</a></td>";
}

echo "</tr>";

echo "<tr>";
echo "<td colspan=\"7\" class=\"gapCell\"></td>";
echo "</tr>";

echo “”;
echo “”;

Any ideas?

Answer 1

$this is used to denote object of class inside the method of class and should be used to access the properties and to call methods inside other method of same class.

public function getFilename()
{
    return $this->_filename;  
}

Remove the call of parent construct from constructor of your class since it is not inheriting from any other class

//parent::__construct();
