In WordPress, you can customize what categories of posts appear on your homepage by utilizing custom functions. The following is a detailed guide, including steps and examples for hiding multiple categories or displaying only a specific category.
Step 1: Find the Category ID
To begin, navigate to the WordPress dashboard and go to Posts → Categories. Hover your cursor over the category you want to hide, and look at the bottom left corner of your browser. You will see a URL that shows the category ID, for example, tag_ID=1 (in this case, the ID is 1).
Step 2: Detailed Explanation for Hiding Specific Categories
1. Hiding Posts from Specific Categories
To hide posts from specific categories on the homepage, you can add the following code to your theme’s functions.php file:
function exclude_categories_from_home($query) {
if ($query->is_home() && $query->is_main_query()) {
$query->set('cat', '-CategoryID1,-CategoryID2'); // Replace with the IDs of the categories to hide
}
}
add_action('pre_get_posts', 'exclude_categories_from_home');
Explanations:
is_home(): Checks if the query is for the homepage.is_main_query(): Ensures that only the main query is modified.set('cat', '-CategoryID1,-CategoryID2'): Excludes multiple categories by prefixing the IDs with a negative sign (-), separated by commas.
2. Showing Only Specific Category Posts
If you want the homepage to display posts from only a specific category, you can use the following code:
function include_specific_category_on_home($query) {
if ($query->is_home() && $query->is_main_query()) {
$query->set('cat', 'CategoryID'); // Replace with the ID of the category to show
}
}
add_action('pre_get_posts', 'include_specific_category_on_home');
Explanations:
- This code utilizes
set('cat', 'CategoryID')to display only the posts from the specified category.
3. Comprehensive Example: Hiding Multiple Categories and Showing One
If you need to hide multiple categories and display a specific one simultaneously, you can combine the two methods as follows:
function websager_customize_home_page($query) {
if ($query->is_home() && $query->is_main_query()) {
$query->set('cat', '-CategoryID1,-CategoryID2,CategoryID3'); // Hide Category 1 and Category 2, show Category 3
}
}
add_action('pre_get_posts', 'websager_customize_home_page');
Note:
Replace “CategoryID1,” “CategoryID2,” and “CategoryID3” with your specific IDs. Always back up the functions.php file before making any changes to prevent potential website issues.
