Recipe Details

3:16 with Alena Holligan

There's a lot more to a recipe then a title and source. In this video we'll be adding the rest of our property to the displayRecipe method, using a simple easy to read format.

Code Sample

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

    Currently our display recipe uses only the title and source properties and 0:00
    returns those to the function call as a single formatted string. 0:04
    The first thing we need to do is start an output variable instead of returning this 0:09
    line directly we're gonna add that to the output variable. 0:13
    We can then return our output variable. 0:25
    We'll keep the title and source as our first line. 0:32
    Then we'll add a new line. 0:35
    We'll use our concatenation and; we'll add a new line character. 0:40
    Our next line will be the tags. 0:44
    We're gonna want to use an implode. 0:57
    We'll separate these with a comma. 1:05
    Let's add another line break. 1:08
    Now we can add our ingredients. 1:13
    Formatting for our ingredients is a little more complicated. 1:17
    So let's loop through the ingredients and format each line. 1:20
    First we'll add the amount. 1:37
    And then we'll add our measure. 1:47
    And finally, our item. 1:55
    We also want to add a new line after each item. 2:01
    Let's add our instructions using implode again. 2:10
    This time we'll separate with a line break. 2:20
    Let's add another line break. 2:30
    And now our yield. 2:38
    Let's take a look at this by running our code. 2:47
    This looks pretty good let's add a couple more line breaks. 2:51
    I want an extra one before our ingredients and an extra line before our instructions. 2:57
    Pull this up and try again. 3:12
    Great. That looks much better. 3:14
