Introducing the default_hidden_columns Hook in WordPress
WordPress is one of the most popular content management systems, providing high flexibility. One of its outstanding features is Hooks that allow developers to modify the default behavior of WordPress or add to it. Hooks are divided into two types: Action and Filter. In this discussion, we will explore the default_hidden_columns hook and how to use it.
The default_hidden_columns hook gives you the ability to specify which default columns on the WordPress management pages should be hidden. For example, you might want to hide some of the default columns to present a simpler view of the data. This feature is very useful for developers who work with management panels.
To use this hook, you first need to define a function that contains the names of the columns you want to hide. Then, you can connect this function with the default_hidden_columns hook. Next, we will discuss how to implement this functionality in detail.
Let's take a look at the code itself and see how you can use this hook to manage the default columns.
add_filter('default_hidden_columns', 'my_hidden_columns', 10, 1);
function my_hidden_columns($hidden) {
$hidden[] = 'column_slug'; // The name of the column you want to hide
return $hidden;
}
Code Explanation
add_filter('default_hidden_columns', 'my_hidden_columns', 10, 1);This line of code tells WordPress to call the
my_hidden_columns function whenever the default_hidden_columns hook is executed.function my_hidden_columns($hidden) {Here, a new function named
my_hidden_columns is defined, which takes an argument called $hidden. This argument includes the default hidden columns.$hidden[] = 'column_slug';In this segment, the name of the column you want to hide is added to the
$hidden array. You must replace column_slug with the actual name of the column you want to hide.return $hidden;This line returns the updated hidden array back to WordPress. Now this column will be hidden by default.
