drupal中页面划分为区块和内容，在page.tpl.php或者page--slh-linghang--slh-linghang-list.tpl.php中的页面调用创建的区块 <div class='test'>
                <?php
               //调用相应的区块
                $block_slh_linghang = module_invoke('slh_linghang', 'block_view', 'slh_linghang_block');
                print render($block_slh_linghang['content']);

                ?>
            </div>
            //page--slh-linghang--slh-linghang-list.tpl.php页面的中间的内容

<?php print render($page['content']); ?>
