Stuck on the 6th OOP Basics Challenge!

Hi,

Once again, I can't figure out what I am missing! Challenge Task 6 of 7 asks me to:

Add a getInfo method to your Trout class that returns a string containing the common_name, flavor, record_weight, and species properties. For example, on our brook trout it might return "Brook Trout tastes Delicious. The record Brook Trout weighed 14 pounds 8 ounces."

Bummer! Try again!

fish.php 
<?php

class Fish
{
    public $common_name;
    public $flavor;
    public $record_weight;

    function __construct($name, $flavor, $record)
    {
        $this->common_name = $name;
        $this->flavor = $flavor;
        $this->record_weight = $record;
    }

    public function getInfo() 
    {
        $output  = "The {$this->common_name} is an awesome fish. ";
        $output .= "It is very {$this->flavor} when eaten. ";
        $output .= "Currently the world record {$this->common_name} weighed {$this->record_weight}.";
        return $output;
    }
}

class Trout extends Fish
{
  public $species;

    function __construct($name, $flavor, $record, $species)
    {
        parent::__construct($name, $flavor, $record);
          $this->species = $species;
    }

    public function getInfo()
    {
        return  $this->species . " " . $this->name . "tastes " . $this->flavor . "." . "The record " . $this->species . " " . $this->name . "weighed " . $this->weight . ".";               
    }

}

 $brook_trout = new Trout("Trout", "Delicious", "14 pounds 8 ounces", "Brook")

 echo $trout->getInfo();
?>

What am I doing wrong? Can someone please help?

So two things.

**I did not check you concatenation real well. Assuming that's okay.

  1. Remember that $name is part of the __construct function, but in the Trout class $name is set to $common_name. So in your getInfo() you can't ask for it's $name, you have to get it's $common_name. Does that make sense?

  2. Earlier you correctly created a variable name $brook_trout and make it a new Trout class. The question specifically asks for information on the Brook Trout, where we added as species, so you would run your getInfo() on the $brook_trout variable, not the $trout variable of the class.

You're welcome. Funny part is I did this lesson myself just a hour or two before you posted questions on the forum, so this stuff was super fresh in my head.

Your concat is good. You just have a couple of small errors

<?php

//you are missing semicolon at end of next line
 $brook_trout = new Trout("Trout", "Delicious", "14 pounds 8 ounces", "Brook")

//as Kevin was suggesting above you want to use $brook_trout below
 echo $trout->getInfo();

?>
