Add Snippet To Project
If your website has been running for more than a year, your archives widget can start to look quite crowded. With every passing month, the list becomes lengthier, ultimately appearing cluttered and overwhelming to visitors. Perhaps you’ve been searching for a way to limit the number of months displayed in the WordPress archives widget. Look no further. In this article, we will guide you through a step-by-step process to limit your archives widget to display only the last 12 months, keeping your website clean and user-friendly.
function wpturbo_limit_archives_widget($args) {
$args['limit'] = 12;
return $args;
}
add_filter('widget_archives_args', 'wpturbo_limit_archives_widget');
The main function that accomplishes our goal here is wpturbo_limit_archives_widget($args). This function is used to alter the arguments for the archives widget in WordPress.
The $args argument represents an array of all the different parameters that can be used to customize the widget. By modifying these values, you can change the behavior of the widget.
Inside our function, we are setting $args['limit'] = 12;. This operation is the key to achieving our desired functionality: what this does is it limits the number of archive links displayed by the widget to the last 12 months only.
What the widget does, in general, is that it collects all your posts, groups them by their publication date, and displays a list of these groups (links to each group) for your visitors to click and access. If you don’t limit the number of archive lists, you could end up with a very long list that may make your website look cluttered, especially if you have been posting for several years.
The number 12 can be replaced with any number you prefer if you want to display more or fewer months.
Next, return $args; is used to pass the modified arguments back to WordPress, which applies these changes to the archive widget. If you forget to return the $args, the modifications you made would not take affect and the widget will operate as per the default settings.
Finally, we have add_filter('widget_archives_args', 'wpturbo_limit_archives_widget');. This line of code is what connects our function to the WordPress system. This is known as "hooking" in WordPress parlance.
In WordPress, hooks are provided to allow your plugin to ‘hook into’ the rest of WordPress; that is, to call functions in your plugin at specific times, and thereby set your plugin in motion. See the Hooks Article for more details.
There are two types of hooks: actions and filters.
- Actions: Actions are the hooks that the WordPress core launches at specific points during execution, or when specific events occur. Your plugin can specify that one or more of its PHP functions are executed at these points, using the Action API.
- Filters: Filters are the hooks that WordPress launches to modify text of various types before adding it to the database or sending it to the browser screen. Your plugin can specify that one or more of its PHP functions is executed to modify specific types of text at these times, using the Filter API.
In this particular example, we used add_filter to hook into widget_archives_args which represents the arguments of the archives widget. So, whenever the archive widget is about to display, it will first pass its default arguments through our function for any potential modifications which in this case limits the archive display to just last 12 months.
