[Wordpress widget - How to display one post category rather than all]

Hi All,

I'm currently trying to find a solution to a problem within a wordpress template I am using. On the homepage, Im using a widget to display recent posts. However, the widget displays all posts, whereas I want it to only display posts from a particular category. What do I need to edit within the php to make this happen?

 

Heres the widget php:

 

 

 

<?php
/**
 * List Blog Posts
 *
 * @since Jobify 1.0
 */
class Jobify_Widget_Blog_Posts extends Jobify_Widget {


/**
* Constructor
*/
public function __construct() {
$this->widget_cssclass    = 'jobify_widget_blog_posts';
$this->widget_description = __( 'Jobify - Display recent blog posts.', 'jobify' );
$this->widget_id          = 'jobify_widget_blog_posts';
$this->widget_name        = __( 'Jobify - Home: Blog Posts', 'jobify' );
$this->settings           = array(
'title' => array(
'type'  => 'text',
'std'   => __( 'Recent News Article', 'jobify' ),
'label' => __( 'Title:', 'jobify' )
),
'description' => array(
'type'  => 'textarea',
'rows'  => 4,
'std'   => '',
'label' => __( 'Description:', 'jobify' ),
)
);
parent::__construct();
}


/**
* widget function.
*
* @see WP_Widget
* @access public
* @param array $args
* @param array $instance
* @return void
*/
function widget( $args, $instance ) {
if ( $this->get_cached_widget( $args ) )
return;


ob_start();


extract( $args );


$title       = apply_filters( 'widget_title', $instance['title'], $instance, $this->id_base );
$description = $instance[ 'description' ];
$posts       = new WP_Query( apply_filters( 'widget_jobify_blog_posts', array( 'posts_per_page' => 3, 'ignore_sticky_posts' => true ) ) );


echo $before_widget;
?>


<div class="container">


<?php if ( $title ) echo $before_title . $title . $after_title; ?>


<?php if ( $description ) : ?>
<p class="homepage-widget-description"><?php echo $description; ?></p>
<?php endif; ?>


<div class="content-grid row">
<?php if ( $posts->have_posts() ) : ?>
<?php while ( $posts->have_posts() ) : $posts->the_post(); ?>
<?php get_template_part( 'content', 'grid' ); ?>
<?php endwhile; ?>
<?php endif; ?>
                        </div>


</div>
                <?php
echo $after_widget;


$content = apply_filters( 'jobify_widget_blog_posts', ob_get_clean(), $instance, $args );


echo $content;


$this->cache_widget( $args, $content );
}
}
