Do not be afraid to read the error description. It doesn't bite;)
In this case problem is next:
*PHP Fatal error: Uncaught Error: Call to undefined method Recipe::getTitle() *
You are trying to invoke method getTitle() from the array element. Which is not correct. if you want to get object then you need to have array of objects that can invoke such method. Another small thing concerns property _title
public function getTitle() { return $this->title; }
should be rewritten to this(you've forgot about underscore)
public function getTitle() { return $this->_title; }
But, if you want to invoke method from foreach loop, you need to redo your code a little.
public function addRecipe($recipe) { $this->_recipes[] = $this; }
public function getRecipeTitles() {
$titles = array();
foreach ($this->_recipes as $_recipe) {
$titles[] = $_recipe->getTitle();
}
return $titles;
}
Above is working version of your code. But it is a mistery to me what are you trying to achieve =)
class RecipeCollection {
private $_title;
private $_recipes = array();
public function __construct($title = null) { $this->setTitle($title); }
public function setTitle($title) {
if(empty($title)) { $this->title = null; }
else
{ $this->_title = ucwords($title);}
}
public function getTitle() { return $this->title; }
public function addRecipe($recipe) { $this->_recipes[] = $recipe; }
public function getRecipes() { return $this->_recipes; }
public function getRecipeTitles() {
$titles = array();
foreach ($this->_recipes as $_recipe) {
$titles[] = $_recipe;
}
return $titles;
}
}
$recipe = new RecipeCollection('One');
$recipe->addRecipe('some desΡription');
print_r($recipe->getRecipeTitles());
Hope that this will explain few things.
Best regards.
