Video: Adding footer information

Just like an artist usually signs her paintings and other works somewhere on the bottom to put her mark on them, so should you put your own information at the bottom of your new child theme so that others can see what you've done. When creating a child theme, I always encourage some coding courtesy. By that I mean you should always say that this is a child theme and reference the original. That way you're both giving props to the people who built the original theme and at the same time you're letting people compare the original to your new and improved child theme.

WordPress 3: Building Child Themes
3h 11m Intermediate Jun 23, 2011 Updated Nov 27, 2012

Viewers: in countries Watching now:

Create a child theme based on an existing parent theme in WordPress and change the functionality, presentation, or styling of your website. In this course, author Morten Rand-Hendriksen shows how to use the default WordPress theme, Twenty Twelve, as a basis for a new child theme and add custom menus; new headers, sidebars, and footers; and index pages with widgets and pagination to your site. The course also demonstrates how to add a responsive welcome message to your front page using PHP and jQuery, and how to edit the many templates found in a WordPress theme. Morten explains how to perform these changes using any code editor, the developer tools in the Chrome browser, and WordPress.

Topics include:
  • Picking a parent theme
  • Creating and activating a basic WordPress child theme
  • Using the developer tools
  • Changing the header image size
  • Using conditional statements for customized effects
  • Adding custom menus to the child theme and/or a template
  • Changing the default footer content
  • Adding featured images to posts
  • Changing the display of meta content (such as date, author, category, etc.)
  • Excluding categories from the front page with custom queries
  • Including functions from external files
  • Identifying and fixing common mistakes

Adding footer information

Just like an artist usually signs her paintings and other works somewhere on the bottom to put her mark on them, so should you put your own information at the bottom of your new child theme so that others can see what you've done. When creating a child theme, I always encourage some coding courtesy. By that I mean you should always say that this is a child theme and reference the original. That way you're both giving props to the people who built the original theme and at the same time you're letting people compare the original to your new and improved child theme.

The logical place to put this information as well as some other information is down here in the footer. In addition to adding information about your child theme, I also like to add a copyright notice with the current year and a link back to this site. That's not strictly necessary, but it's a good idea to just remind people that when they see things online someone actually owns to copyright to that content. So let's start by adding the copyright notice. I'll go to my child theme, open footer.php, and find where I want to put this information.

I'm going to put it after this action call here, and I'll start with a copyright notice. I wanted to say Copyright and then I want to put in that copyright symbol, the circle with the C inside it and then I want to put in the year. Here I'm going to use a PHP function to call up the year. I'll say echo date, capitalized Y. This will print out the current year and then I want to put in a link to the current site. So I'll say a href= and then I'm going to use a WordPress function that will return the URL to the main site's homepage.

So I'll say php echo and the function is called home_url and because it's a link I need to give it a title. The title should be the name of the site, so here I'm going to use another function from WordPress, this one called bloginfo ('name') and this will simply print out the name of the site as you've said it inside WordPress. And then I'm going to copy this, end my tag and paste it in again because I wanted the actual text of the link to say the name of the site.

And then I will end my anchor tag and put a punctuation mark at the end. I'm going to save this and test it in my browser just to say that everything works, and now we can see it says Copyright with a copyright symbol, Twenty Twelve Red 30 Blog. That's great. Now I need to add the information about the parent theme and the child theme. Back in footer.php, I'll say Twenty Twelve child theme by Morten Rand-Hendriksen.

And then I want to wrap Twenty Twelve in an anchor so that people can go and check out Twenty Twelve, a href= and then I made the URL to Twenty Twelve and I have it up here, this points directly to Twenty Twelve in the themes directory. So I'll copy that URL, paste it in, title="Twenty Twelve" and I'll also set a target so that it opens in a separate window, blank and then I'll end my anchor on the other end of Twenty Twelve.

I will save it again, reload my site, and now you see it says Copyright 2012, Red 30 Blog, and here there is a link to Twenty Twelve that says Twenty Twelve child theme by Morten Rand-Hendriksen, Proudly powered by WordPress. If I click Twenty Twelve, opens a new window and here's Twenty Twelve. With a favicon, a screen shot, and a custom footer, your child theme is complete. Congratulations.

Q: The 2010 version of this course no longer covers installing BitNami. Can you provide directions?
A: Instructions on how to install WordPress using BitNami can be found at
 http://bitnami.org/stack/wordpress. Use the "Installer" option. 
It is pretty straight forward and almost impossible to mess up.

lynda.com also has a dedicated course on WAMP and MAMP (Installing Apache, MySQL, and PHP) that is relevant and you might find helpful.
Q:When looking to download PHP development tool at www.eclipse.org/pdt/, as advised by Morten, but when accessing the site via this link, the screenshot in the movie is very different from what it takes you to on the website.
A: Eclipse has a very active developer cycle and updates quite frequently. The interface changes all the time. I recommend using Notepad++ (Windows) or TextWrangler (Mac) instead. They perform the same function but are far less cumbersome to deal with.
Q: This course was updated on 11/27/2012. What changed?
A: This course was heavily revised to reflect changes to the default WordPress parent theme, Twenty Twelve, and updates to WordPress's functionality. The entire course was re-recorded to reflect changes to the interface. Then we added new movies on text styling, the Related Posts feature, and the welcome message features. There are also two brand new chapters, "Modifying and Adding Functions" and "Working with Featured Images." We recommend that members who have seen the whole course start again from the beginning to get the most benefit from this update.
