在我的推荐信部分，没有显示标题和内容。功能图像显示时，每个图像都附加了额外的图像。我不熟悉php和word press。使用WP 4.9（以下是我的代码）

<div class="col-sm-8 col-sm-offset-2">
    <h2>What People Are Saying About Brad</h2>
    <?php $loop = new WP_Query( array( \'post_type\' => \'testimonials\', \'orderby\' => \'post_id\', \'order\' => \'ASC\' ) ); ?>  

    <?php while( $loop->have_posts() ) : $loop->the_post(); ?>

<div class="row testimonial">
    <div class="col-sm-4">

    <?php if ( has_post_thumbnail() ) { 
               the_post_thumbnail( array() );
           }    
        ?>

        <img src="<?php bloginfo(\'stylesheet_directory\'); ?>/assets/img/brennan.jpg" alt="Brennan">
    </div><!-- end col -->
    <div class="col-sm-8">                          

        <blockquote>
            <?php the_content; ?>
            <cite>&mdash;<?php the_title; ?></cite>
        </blockquote>

    </div><!-- end col -->

</div><!-- row -->                  
<?php endwhile; ?>
