thinkphp模板使用if判断

  <if condition="$vo['user_group']['user_group_id'] eq 2">
                            <img src="/addons/theme/stv1/_static/image/usergroup/v_07.png" style="width:22px;padding-top:5px;" alt="{:L($vo['user_group']['user_group_title'])}">
                            <elseif condition="$vo['user_group']['user_group_id'] eq 5" />
                            <img src="/addons/theme/stv1/_static/image/usergroup/v_06.png" style="width:22px;padding-top:5px;" alt="{:L($vo['user_group']['user_group_title'])}">
                       <else />
                        </if>
