现在，当我使用post格式时，我的摘录翻了一番。我希望在未选择帖子格式时有一个默认摘录。签出示例：http://themeforward.com/demo2/

对于我的摘录，要调用post格式，我使用以下代码：

<?php
if ( has_post_format( \'aside\' )) {
    ?>
    <span class="icon-aside"></span>
    <a href="<?php the_permalink() ?>">
    <?php if ( has_post_thumbnail() ) { the_post_thumbnail( \'thmb-index\' ); } ?>
    </a>
    <span class="sub-title">Posted <?php the_time("F j, Y"); ?> by <?php the_author_posts_link(); ?> in <?php the_category(\', \') ?></span>
    <span class="index_title"><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></span>
    <?php the_excerpt();
}
if ( has_post_format( \'chat\' )) {
    ?>
    <span class="icon-chat"></span>
    <a href="<?php the_permalink() ?>">
    <?php if ( has_post_thumbnail() ) { the_post_thumbnail( \'thmb-index\' ); } ?>
    </a>
    <span class="sub-title"><?php the_time("F j, Y"); ?> &nbsp;/&nbsp; <?php the_author_posts_link(); ?> &nbsp;/&nbsp; <?php the_category(\', \') ?></span>
    <span class="index_title"><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></span>
    <?php the_excerpt();
}
if ( has_post_format( \'gallery\' )) {
    ?>
    <span class="icon-gallery"></span>
    <a href="<?php the_permalink() ?>">
