I've been banging on the following error for awhile and I cannot tell what is wrong, please help:
Catchable fatal error: Argument 2 passed to ShapeFactory::Create() must be an array, string given, called in /home/content/14/11625314/html/AdvPHPwOOP/factory.php on line 22 and defined in /home/content/14/11625314/html/AdvPHPwOOP/ShapeFactory.php on line 11
I'm using PHP 5.3 thru goDaddy
Here's the code:
<!doctype html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>Factory</title>
<link rel="stylesheet" href="style.css">
</head>
<body>
<?php # Script 7.4 - factory.php
// This page uses the ShapeFactory class (Script 7.2).
// Load the class definitions:
require('ShapeFactory.php');
require('Shape.php');
require('Triangle.php');
require('Rectangle.php');
// Minimal validation:
if (isset($_GET['shape'], $_GET['dimensions'])) {
// Create the new object:
$obj=ShapeFactory::Create($_GET['shape'],$_GET['dimensions']);
// Print a little introduction:
echo "<h2>Creating a {$_GET['shape']}...</h2>";
// Print the area:
echo '<p>The area is ' . $obj->getArea() . '</p>';
// Print the perimeter:
echo '<p>The perimeter is ' . $obj->getPerimeter() . '</p>';
} else {
echo '<p class="error">Please provide a shape type and size.</p>';
}
// Delete the object:
unset($obj);
?>
</body>
