Display all posts in category wordpress

Question

I am trying to display all posts in the category on the category archive page.
I have used the following code, but it displays all posts from all categories.

Can someone help me please?

<?php 
// the query
$wpb_all_query = new WP_Query(array('post_type'=>'post', 'post_status'=>'publish', 'posts_per_page'=>-1)); ?>

<?php if ( $wpb_all_query->have_posts() ) : ?>

<ul>

    <!-- the loop -->
    <?php while ( $wpb_all_query->have_posts() ) : $wpb_all_query->the_post(); ?>
        <li><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></li>
    <?php endwhile; ?>
    <!-- end of the loop -->

</ul>

    <?php wp_reset_postdata(); ?>

<?php else : ?>
    <p><?php _e( 'Sorry, no posts matched your criteria.' ); ?></p>
<?php endif; ?>

Thanks

You need to add a category parameter to the WP_Query array. Check this reference in the "Category Parameters" section: https://codex.wordpress.org/Class_Reference/WP_Query

Something like this should work:

$wpb_all_query = new WP_Query(array(
    'post_type' => 'post',
    'post_status' => 'publish',
    'posts_per_page' => -1,
    'category_name' => 'your_category_slug'
));
