Code snippet: Show all category information for example on the front page

This is a code snippet that shows all the category information for example on the front page.

It uses get_categories(). It will display the get_categories() array, as well as echo a ‘test’ value, and the value you wish to have shown. The code as shown should be used outside the loop.

It can be handy when for example you are designing a theme, and you want to build a dynamic code part.

Do not paste the code snippet below in a live website.

<?php 

     $categories = get_categories(); 

    	 	print_r($categories);

     foreach ($categories as $category) {

    		echo 'test<br />';

     		echo $category->category_parent . '<br />';

     }

    ?>

The example shows the ids’ of all of the parent categories.

You can substitute this with any other array field available in the get_categories() function.

For example:

echo $category->category_parent

to:

echo $category->cat_name

Which will then display all the category names.

Depending on your needs you can choose to build from there.
