One of my getters won't print when I return this method:

I am working on Object-Oriented PHP Basics and I don't know why one of my getters is not printing when I return the method, because the other ones work fine.

<?php

class Render
{
   public static function displayRecipe($recipe)
  {
     $output = "";
     $output .= $recipe->getTitle() . " by " . $recipe->getSource();
     $output .= "\n";
     $output .= implode(", ",$recipe->getTags());
     $output .= "\n";
     foreach ($recipe->getIngredients() as $ing){
        $output .= $ing["amount"] . " " . $ing["measure"] . " " . $ing["item"];
        $output .= "\n";     

}
     $output .= "\n";
     $output .= implode("\n", $recipe->getInstructions());
     $output .= $recipe->getYield();

     return $output;
  } 
}

I don't think there's a problem with the code shown above, but luckily everything is in the snapshot.

You forgot to mention which "one of" you were having trouble with, but on first glance it looks like on line 57 of recipes.php, addInstruction loads a string into "instruction" (singular), but on line 64 getInstructions returns "instructions" (plural).

Does fixing that clear up the issue?

I thought that might be the issue at first, but the addIngredient method is formatted that same way and works fine. And that is the way it is done in the video as well.

You didn't link this question to the course page, so I couldn't check the video. But in your snapshot, the getter/setter for ingredients both use the same variable name spelling. Lines 42 and 51 both have $this->ingredients (plural).

To make instructions work the same, line 57 needs the letter "s" added to the variable name to make it match line 51.

That worked, thank you!
