Why is WP_Query not working with category_name?

1 Views

Why on earth is this piece of code not working? 

    $my_query = new WP_Query('category_name=feature');
    while ($my_query->have_posts()) : $my_query->the_post();
        echo 'test';
    endwhile;

I’ve tried with Feature and feature, no difference.
I need to get post by category name.

Any help appreciated.

update

This is not working either: $my_query = new WP_Query('cat=3');

code 

// index.php

<?php
    include_once('header.php');
?>

<div id="fp-slider-container" class="blue-gradient">
    <div class="main-content-container">
        <?php
        query_posts( 'cat=3&posts_per_page=5' );

        while ( have_posts() ) : the_post();
            echo 'test';
        endwhile;


        ?>
    </div>
</div>

<?php
    include_once('footer.php');
?>

  2. instead of hacking index.php why not use the pre_get_posts filter?

    add_filter('pre_get_posts', 'filter_homepage_posts');
function filter_homepage_posts($query) {
    $limit_number_of_posts = 5;
    $featured_category_id = get_cat_id('Reviews'); // by cat name...
    if ($query->is_home) {
        $query->set('cat', $featured_category_id);
        $query->set('showposts', $limit_number_of_posts);
    }
  return $query;
}

    should also work like this since technically the query passes by reference

    add_action('pre_get_posts', 'filter_homepage_posts');
function filter_homepage_posts( $query) {
    $limit_number_of_posts = 5;
    $featured_category = 'bacon-category'; // by cat slug...
    if ($query->is_home) {
        $query->set('category_name', $featured_category);
        $query->set('showposts', $limit_number_of_posts);
    }
  return $query;
}

  3. As Hexodus mentioned, category_name actually requires a category slug.

    If you’re determined to use the actual category name as an input, then you can do something like this:

    $args['category_id'] = get_cat_ID('Category Name');

    or this:

    $args['category_name'] = (get_category(get_cat_ID('Category Name'))) -> slug;
