You’re assigning a value to $dish
, but then not using it…
Try the following. It takes advantage of the fact that your image for “gluten” is named gluten.png
, etc. You’ll be able to add more tags by just adding to the $images
array.
$images = array(
"gluten" => "Gluten Free",
"vegan" => "Vegan Friendly",
"vegetarian" => "Vegetarian"
);
$dish_tags = (array) get_field('diet_friendly');
foreach ($images as $image_name => $alt) {
if (in_array($image_name, $dish_tags)) {
echo '<img src="' . get_template_directory_uri() . '/images/' .
$image_name . '.png" alt="' . $alt . '" />';
}
}
