What am I doing wrong here? - Object Oriented PHP - Building the recipe - Controlling the Class code challenge

This is what I have, and it seems like it should work, but it keeps telling me that task one no longer passes.

<?php class Fish { public $common_name; public $flavor; public $record_weight;

public function getInfo() {
  return "A {$this->common_name} is an {$this->flavor} flavored fish. The world record weight is {$this->record_weight}.";
public function __construct($name, $flavor, $record) {
  $this->common_name = $name;
  $this->flavor = $flavor;
  $this->record_weight = $record;
$bass = new Fish();
$bass->name = "Largemouth Bass";
$bass->flavor = "Excellent";
$bass->record = "22 pounds 5 ounces";

The problem is that you are trying to reference the parameters ($name, $flavor, $record) in the constructor-function, "through the object itself".

This technique is doable, however you have to point to the public properties ($common_name, $flavor $record_weight), instead of the constructor-parameters ($name, $flavor, $record)

The answer should then look something like this

$bass = new Fish();
$bass->common_name = "Largemouth Bass"; // Notice I'm not pointing to $name, but $common_name
$bass->flavor = "Excellent";
$bass->record_weight = "22 pounds 5 ounces";

Although the Treehouse task would accept this answer, I strongly recommend you instead place the values into the Fish-object when you instantiate it. This is faster and much more secure.

$bass = new Fish("Largemouth Bass", "Excellent", "22 pounds 5 ounces"); 

Hope this answers your question :)
