How to detect when get_template_part() WordPress function fails

Nowadays, in most of modern WordPress themes, the function get_template_part() is one of their essential elements. It just takes review the structure of, for example the last official themes (…, Fourteen, Fifteen, Sixteen), to realize that WordPress themes have evolved, from a structure quite monolitic to a structure driven by content and formats. And one of the keys to this evolution is the get_template_part () function.

get_template_part() it’s actually an invaluable element of any modern WordPress theme that through its two parameters allows us to select dynamically what .php file (what part) is going to be loaded for displaying the current page (see the official documentation for further information) however, one of its characteristics is that Continue reading…

Using Post Formats with your custom WordPress Post Types

Since versión 3.1, WordPress introduced a new theme feature called Post Formats that, basically, allows us to divide a regular WordPress Post Type in subsets based on the nature of the information that a post includes, ie, you can have regular posts, but you can also have posts that specifically contain a video, or an image, etc. In case of the Post Type post, most of the popular WP themes already includes support for styling its Post Formats but, what can we do for using Post Formats in case of our custom Post Types?

The proposed method is quite easy and it simply extends the habitually used technic for dealing with Post Formats inside WordPress templates, in other words, we’ll create a refined system for loading the content-{$post_format_slug}.php subtemplates. Continue reading…

How to change the WordPress post updated messages of the edit screen

WordPress posts edit interface has got a good information messages system for all user actions. It doesn’t matter what is the done action, WordPress talks to us: draft saved, post updated, published… Actually, it’s a perfect information system if regulary you only publish posts or sometimes a new page, ie, if you have just got a blog but, when your website has other kinds of information (films, cats, recipies, products…) WordPress keeps saying “post updated” and in fact, you are editing an actor’s profile, or a recipe, or whatever, but not a post… Would not it be awesome that WordPress says “Actor profile updated”, or “Recipe improved” or any message more like the natural language? So, if you don’t want that WordPress talks like a machine, you need use post_updated_messages.

Some examples of WordPress post updated messages on the edit screen

I’m sure that if your website talks about recipes, or actor profiles (whatever that is not a post), you are used to use the WP function register_post_type but probably you don’t know that there is another option that works together with register_post_type that allows us also to change the information messages related with these new kinds of information Continue reading…

Constructing WP themes or plugins that take into account future gender translations (2)

Few days ago I began a serie of articles about how to design a WordPress Theme that facilitates that in the future it is possible to make a translation that takes into account the gender. In the first article I suggested a little technique to mark the Post Type (and for extension Taxonomy) objects including a new property that keeps the gender of the object and that depends on the translation today I’m going to extend this technique also for the labels of the Post type inside the Admin interface.

As we saw, the core of the first proposal consists in adding one more line inside the array that is used to register any post type Continue reading…

Using the Post Type description in WordPress Themes

Sometimes, especially in the case of an items list, apart from the header/title of the list, we would want to add some text as an introduction for these items: a global suggestion, perhaps a couple of interesting links, a descriptive or in detail approach about the items, a definition, etc. When the items to list are inside a Category or a Tag, to add a header with description is obvious because, simply taking a look to the screen for editing terms, all of us know that they have a description but, do you know that post types have also got a description, and that you can use it in your themes?

An example of using the Post Type description in WordPress Themes

Yes, in the same way that with the terms of a taxonomy, WordPress Post Types have also got a field to add a description thus, you can use this property of the Post Type object to introduce any text that you want and Continue reading…

Checkbox fields in WordPress Metaboxes a solution for NULL values

Talking about forms, one of the most common issues is that checkbox fields don’t return any value when they are not checked. We just receive their values -usually TRUE- when they are checked but if they are unchecked they ‘say’ nothing. What can we do?

Checkbox fields in WordPress Metaboxes a solution for NULL values

This behavior of checkboxes fields is not an error, long time ago they was designed in that way (they are silent) however, in most cases,  this behaviour is a problem because the lacking of value doesn’t allow developers to know whether there is not actually a value, or if the value is actually FALSE. There is not difference between NOTHING and FALSE so Continue reading…

How to add a Metabox. A step by step approach. add_meta_box

The WordPress posts edit Tool is not an unique compact module that shows all the boxes that appear on the screen but it’s a set of different little modules –called metaboxes– working together. A little module controls the title, another one controls the visual editor, another one defines the publishing options and actions, another one is for the Post Format… the Categories, the Author’s post, etc. The reason of this modular design is to allow developers to introduce easily new boxes (or remove some ones) in the Edit Screen.

So thanks to this modular design, we can create our metaboxes for adding new functionalities or data to the WordPress Posts Continue reading…

How to show all post types in Front Page results

Every day more websites use the Post Types extension of WordPress. They are not publishing just (simple) posts but they publish recipes, people profiles, city reviews, testimonials, or whatever you could imagine. It’s fantastic to be able to works easily with all these kinks of different information both in Front End and Back End however, when you access to your Front Page these Post Types aren’t shown in the results list of the main query. Are they shy? What can we do?

Constructing WP themes or plugins that take into account future gender translations

Actually, there is not a simple solution for avoid the gender issue if you are translating a WP theme or plugin to languages that take into account the gender for selecting the words of a sentence. Simple, try to substitute the gendered words or expression for others that feet into the sentence without too many problems… But if you are not translating but creating a new theme or plugin you can use a simple set of techniques –better maybe suggestions–, that will allow future translators for dealing to this kind of problems with better results. Let’s go to see three simple proposals.

But, before to go to the solution, let me show you a tiny example of this kind of gender issues. Continue reading…
