帖子类型显示帖子而不是页面

Question

我正在使用名为 Spacious 的主题在wordpress网站上工作。该主题支持小部件将某些页面显示为最近的作品。小部件名称为 TG：精选小工具。这是我从主题核心文件中获得的代码。

/**
 * Featured recent work widget to show pages.
 */
class spacious_recent_work_widget extends WP_Widget {
function spacious_recent_work_widget() {
    $widget_ops = array( 'classname' => 'widget_recent_work', 'description' => __( 'Show your some pages as recent work. Best for Business Top or Bottom sidebar.', 'spacious' ) );
    $control_ops = array( 'width' => 200, 'height' =>250 ); 
    parent::WP_Widget( false, $name = __( 'TG: Featured Widget', 'spacious' ), $widget_ops, $control_ops);
}

function form( $instance ) {
    for ( $i=0; $i<3; $i++ ) {
        $var = 'page_id'.$i;
        $defaults[$var] = '';
    }
    $att_defaults = $defaults;
    $att_defaults['title'] = '';
    $att_defaults['text'] = '';
    $instance = wp_parse_args( (array) $instance, $att_defaults );
    for ( $i=0; $i<3; $i++ ) {
        $var = 'page_id'.$i;
        $var = absint( $instance[ $var ] );
    }
    $title = esc_attr( $instance[ 'title' ] );
    $text = esc_textarea($instance['text']);
    ?>

    <p>
        <label for="<?php echo $this->get_field_id('title'); ?>"><?php _e( 'Title:', 'spacious' ); ?></label> 
        <input id="<?php echo $this->get_field_id('title'); ?>" name="<?php echo $this->get_field_name('title'); ?>" type="text" value="<?php echo $title; ?>" />
    </p>

            <?php wp_dropdown_pages( array( 'show_option_none' =>' ','name' => $this->get_field_name( key($defaults) ), 'selected' => $instance[key($defaults)] ) ); ?>
        </p>
    <?php
    next( $defaults );// forwards the key of $defaults array
    }
}

function update( $new_instance, $old_instance ) {
    $instance = $old_instance;
    $instance[ 'title' ] = strip_tags( $new_instance[ 'title' ] );
    for( $i=0; $i<3; $i++ ) {
        $var = 'page_id'.$i;
        $instance[ $var] = absint( $new_instance[ $var ] );
    }
    if ( current_user_can('unfiltered_html') )
        $instance['text'] =  $new_instance['text'];
    else
        $instance['text'] = stripslashes( wp_filter_post_kses( addslashes($new_instance['text']) ) ); // wp_filter_post_kses() expects slashed
    $instance['filter'] = isset($new_instance['filter']);

    return $instance;
}

function widget( $args, $instance ) {
    extract( $args );
    extract( $instance );

    global $post;
    $title = isset( $instance[ 'title' ] ) ? $instance[ 'title' ] : '';
    $text = apply_filters( 'widget_text', empty( $instance['text'] ) ? '' : $instance['text'], $instance );
    $page_array = array();
    for( $i=0; $i<3; $i++ ) {
        $var = 'page_id'.$i;
        $page_id = isset( $instance[ $var ] ) ? $instance[ $var ] : '';

        if( !empty( $page_id ) )
            array_push( $page_array, $page_id );// Push the page id in the array
    }
    $get_featured_pages = new WP_Query( array(
        'posts_per_page'            => -1,
        'post_type'                 =>  array( 'page' ),

            <p><?php echo esc_textarea( $text ); ?></p>
        </div>
            <?php
            $i=2;
            while( $get_featured_pages->have_posts() ):$get_featured_pages->the_post();
                if ( $i % 4 == 0 ) { $class = 'tg-one-fourth tg-one-fourth-last'.' tg-column-'.$i; }
                elseif( $i % 3 == 0 ) { $class= 'tg-one-fourth tg-after-two-blocks-clearfix'.' tg-column-'.$i; }
                else { $class = 'tg-one-fourth'.' tg-column-'.$i; }
                $page_title = get_the_title();
                ?>  
                <div class="<?php echo $class; ?>">
                    <?php 
                    if ( has_post_thumbnail( ) ) {
                        echo '<div class="service-image"><a title="'.get_the_title().'" href="'.get_permalink().'">'.get_the_post_thumbnail( $post->ID,'featured-blog-medium').'</a></div>';                
                    }
                    ?>
                </div>          
            <?php 
                $i++;
            endwhile;
            // Reset Post Data
            wp_reset_query(); 
            ?>
    <?php echo $after_widget;
    }
}

上面的代码部分有下面的spinet，要求发布帖子类型。已经给出了页面。我将其更改为＆＃39; post＆＃39;

$get_featured_pages = new WP_Query( array(
        'posts_per_page'            => -1,
        'post_type'                 =>  array( 'page' ),
        'post__in'                  => $page_array,
        'orderby'                   => 'post__in'
    ) );

仍然无法正常工作，有人可以帮忙吗？
