    Customizing the WordPress Admin: The Login ScreenCustomize wordpress admin rachel 400
    The WordPress login screen is well designed - it's clean and simple to interact with and it works well on all screen sizes. But what if you're building a site for a client who wants to display their own logo to users logging in? Or if you have a MultiSite installation and want your users to see your branding when they log in? Luckily, you can customise the way the login screen looks quite easily. For this tutorial I've created a plugin to do this; the advantage of using a plugin is that you can drop it into any WordPress sites you develop and instantly give them some branding.Read More…

    Applying Categories, Tags and Custom Taxonomies to Media AttachmentsAttachment taxonomies image 400
    Have you ever been frustrated by the fact that WordPress doesn't let you assign categories or tags to your images or uploaded media? Imagine how useful it could be: you could create dynamic galleries of images from specific places or of specific types (landscapes, abstracts etc.), or you could create listings pages for sites with a large number of PDF attachments. The great news is that this is surprisingly easy to achieve. You can add categories and tags to your attachments with the addition of some simple code to your theme functions file or to a plugin, and you can also create a custom taxonomy that applies to attachments. In this tutorial I'll show you how to do this, and, even better, in 10 minutes or less!Read More…

    Create a Shortcode to List Posts With Multiple ParametersPost listing shortcode main image400
    On many of the client sites I build, I find there are times when I need to include a post listing on a page. I'm not talking about archive pages here, but adding a custom listing to an existing static page. For example, I might want to list some posts on the 'About' page, or the site may require an in-depth page for a topic, with a list of posts and custom post types related to that topic. One way to do this is by creating a custom page template to include the current page content plus the results of a second custom query, but if you want more flexibility over how you list posts, or just want to do it a few times, a shortcode will be a simpler solution. In this tutorial, I'll show you how to create a simple shortcode to list all posts of a custom post type, and then I'll expand on that to create a shortcode with various parameters that users can specify to list posts however they want.Read More…

    How to Create a Homepage With Multiple Listings Using Custom QueriesFrontpage custom queries preview 400
    WordPress gives you a couple of built-in options for your website's front page: a display of your most recent blog posts or a static page of your choice. But what if you want to create something a bit more interesting than that? If your site has a lot of data using categories, taxonomies or custom post types to organize it, you might want to display data of more than one kind on your homepage. The good news is that you can do this using a custom template for the homepage. In this template you write a number of custom queries to list the data in the way you want to. In this tutorial you'll learn how to do the following: Create a custom homepage template for use by your theme Include four queries in that template to display different kinds of data, including three custom queries The queries will list standard posts plus one custom post type registered for this project, called 'animal'. You can find the template file with the four queries in the code bundle.Read More…

    In Part 1 of this tutorial you learned how to create a template file for a custom post type in order to display featured images and titles for each post.
