Add Instagram Info to Recipe Card

functions.php

<?php
//* Do NOT include the opening php tag

add_action( 'cookbook_recipe_after', 'cookbook_recipe_instagram', 10 );
/**
 * Display the Instagram Information.
 */
function cookbook_recipe_instagram() {
	echo '<div ' . cookbook_get_attr( $recipe, 'instagram' ) . '>';
		echo '<i class="fa fa-instagram fa-5x fa-pull-left"></i>';
		echo '<h4>Did you make a recipe?</h4>';
		echo '<p>Tag <a href="http://instagram.com/cookbookplugin" target="_blank">@cookbookplugin</a> on Instagram and hashtag it <strong>#cookwithcookbook</strong>.</p>';
	echo '</div>';
}

style.css

.cookbook-instagram {
	background: #333;
	color: #fff;
	margin: -20px auto 0;
	padding: 20px;
}

.cookbook-instagram h4 {
	color: #fff;
	margin: 3px 0 5px;
}

.cookbook-instagram a {
	color: #fff;
	text-decoration: underline;
}

.cookbook-instagram a:focus,
.cookbook-instagram a:hover {
	color: #55585a;
}

.cookbook-instagram p {
	margin-bottom: 0;
}

@media screen and (min-width: 500px) {
	.cookbook-instagram {
		margin: -20 auto 0;
		padding: 30px;
    }
}

I was getting an error with the cookbook_recipe_instagram function, it looks like it's missing the $recipe parameter:

function cookbook_recipe_instagram( $recipe ) {
	echo '<div ' . cookbook_get_attr( $recipe, 'instagram' ) . '>';
		echo '<i class="fa fa-instagram fa-5x fa-pull-left"></i>';
		echo '<h4>Did you make a recipe?</h4>';
		echo '<p>Tag <a href="http://instagram.com/cookbookplugin" target="_blank">@cookbookplugin</a> on Instagram and hashtag it <strong>#cookwithcookbook</strong>.</p>';
	echo '</div>';
}
