[Theme: DW Focus]

Hi, I’m using a newspaper theme called DW FOCUS by DesignWall. The theme features a “lastest news” widget that retrieves the last published news and displays them as a vertical list. The appearence is ok and it works for my purposes: problem is I don’t want to show the LATEST news BUT the news from a precise category.

I don’t know exactly what to alter but I think the involved files are the following:

<?php
class dw_focus_lastest_news extends WP_Widget {

    /**
     * Register widget with WordPress.
     */
    function __construct() {
        parent::__construct(
            'dw_focus_lastest_news', // Base ID
            __('DW Focus: Lastest news', 'dw_focus'), // Name
            array( 'description' => __( 'Display latest news', 'dw_focus' ), ) // Args
        );
    }

    /**
     * Front-end display of widget.
     *
     * @see WP_Widget::widget()
     *
     * @param array $args     Widget arguments.
     * @param array $instance Saved values from database.
     */
    public function widget( $args, $instance ) {
        $title = apply_filters( 'widget_title', $instance['title'] );

        echo $args['before_widget'];
        if ( ! empty( $title ) )
            echo $args['before_title'] . $title . $args['after_title'];
            ?>
            <?php if ( have_posts() ) : ?>
                <div class="content-inner">
                    <?php while ( have_posts() ) : the_post(); ?>
                        <?php get_template_part( 'content', 'archive' ); ?>
                    <?php endwhile; ?>
                </div>
                <?php dw_focus_pagenavi(); ?>
            <?php else : ?>

                <?php get_template_part( 'no-results', 'archive' ); ?>

            <?php endif; ?>

            <?php
        echo $args['after_widget'];
    }

    /**
     * Back-end widget form.
     *
     * @see WP_Widget::form()
     *
     * @param array $instance Previously saved values from database.
     */
    public function form( $instance ) {
        if ( isset( $instance[ 'title' ] ) ) {
            $title = $instance[ 'title' ];
        }
        else {
            $title = __( 'Lastest News', 'dw_focus' );
        }
        ?>
        <p>
        <label for="<?php echo $this->get_field_id( 'title' ); ?>"><?php _e( 'Title:' ); ?></label>
        <input class="widefat" id="<?php echo $this->get_field_id( 'title' ); ?>" name="<?php echo $this->get_field_name( 'title' ); ?>" type="text" value="<?php echo esc_attr( $title ); ?>">
        </p>
        <?php
    }

    /**
     * Sanitize widget form values as they are saved.
     *
     * @see WP_Widget::update()
     *
     * @param array $new_instance Values just sent to be saved.
     * @param array $old_instance Previously saved values from database.
     *
     * @return array Updated safe values to be saved.
     */
    public function update( $new_instance, $old_instance ) {
        $instance = array();
        $instance['title'] = ( ! empty( $new_instance['title'] ) ) ? strip_tags( $new_instance['title'] ) : '';

        return $instance;
    }

}

// register dw_focus_lastest_news widget
function register_dw_focus_lastest_news() {
    register_widget( 'dw_focus_lastest_news' );
}
add_action( 'widgets_init', 'register_dw_focus_lastest_news' );

As far as I understand this file calls content-archive.php, but I really can’t understand how the template uses it and what to alter to have my news coming from only one hard-coded categpry:

<?php
/*
 * The template for displaying content on the archive page.
 */
?>

    <?php
        global $archive_i; $class = '';
        if( isset($archive_i) && $archive_i % 3 == 0 ) {
            $class = 'first';
        }
        if( has_post_thumbnail( get_the_ID() ) ) {
            $class .= ' has-thumbnail';
        }
    ?>
    <article id="post-<?php the_ID(); ?>" <?php post_class($class); ?> >
        <?php if( has_post_thumbnail() ) : ?>
        <div class="entry-thumbnail">
            <a href="<?php the_permalink(); ?>" title="<?php echo esc_attr( sprintf( __( 'Permalink to %s', 'dw_focus' ), the_title_attribute( 'echo=0' ) ) ); ?>" rel="bookmark">

                <?php if ( has_post_format('Video') || has_post_format('Audio') || has_post_format('Gallery')) : ?>
                    <?php echo dw_focus_post_format_icons(); ?>
                <?php endif ?>

                <?php if( $archive_i == 1 ): ?>
                    <?php the_post_thumbnail('large'); ?>
                <?php else: ?>
                    <?php the_post_thumbnail('medium'); ?>
                <?php endif; ?>
