Limit the number of post

Hi there,

you can use a PHP snippet like this to change the posts per page for a specific category:

add_action('pre_get_posts', 'custom_posts_per_page');
function custom_posts_per_page($query) {
    if (is_category( 'category-slug' );) {
        $query->set('posts_per_page', 10);
    }
}

But, I would like use in home page, the homepage use all categories and all cateogries. How can I add this code? With hook of elements?

On the home page, you could do this:

add_action( 'pre_get_posts', function( $query ) {
    if ( is_admin() || ! $query->is_main_query() ) {
        return;
    }

    if ( is_home() ) {
        $query->set( 'posts_per_page', 9 );
    }
} );

The code can be added like this: https://docs.generatepress.com/article/adding-php/

Now perfect, thanks!!

You're welcome :)

A last question, how can I change the number of the posts in a category? The before code and the plugin code snippet don't run.

Hi there,

you can use the is_category() conditional tag:

https://developer.wordpress.org/reference/functions/is_category/

add_action( 'pre_get_posts', function( $query ) {
    if ( is_admin() || ! $query->is_main_query() ) {
        return;
    }

    if ( is_home() ) {
        $query->set( 'posts_per_page', 9 );
    }
    if ( is_category('your-category-slug') ) {
        $query->set( 'posts_per_page', 9 );
    }
} );

yes, ok, but how I do add this code? so that remove when update the theme, can I use any plugin? or in the elements, hook?

Try one of these methods:

Thanks, it's worked!

add_action( 'pre_get_posts', function( $query ) {
    if ( is_admin() || ! $query->is_main_query() ) {
        return;
    }

    if ( is_category() ) {
        $query->set( 'posts_per_page', 9 );
    }
} );

Glad to hear :)

Thanks ;)

No problem :)

Hello, which PHP needs to be described here? The Archive.php in the theme?
