代码如下:

{php $LETTER = array(‘a’, ‘b’, ‘c’, ‘d’, ‘e’, ‘f’, ‘g’, ‘h’, ‘i’, ‘j’, ‘k’, ‘l’, ‘m’, ‘n’, ‘o’, ‘p’, ‘q’, ‘r’, ‘s’, ‘t’, ‘u’, ‘v’, ‘w’, ‘x’, ‘y’, ‘z’);}
{loop $LETTER $l}
<a href=”?letter={$l}” target=”_self” id=”letter_{$l}”>{$l}</a>
{/loop}

查询:

{php $lt = $_GET['letter'];}
{if empty($lt)}
<!–{tag(“moduleid=$moduleid&table=category&condition=moduleid=$moduleid and level=1&order=item desc&showpage=1&areaid=$cityid&page=$page&pagesize=”.$MOD[pagesize].”&template=xxx-list&dtpre=$DT_PRE”)}–>
{else}
<!–{tag(“moduleid=$moduleid&table=category&condition=moduleid=$moduleid and level=1 and letter=’”.$lt.”‘&order=item desc&showpage=1&areaid=$cityid&page=$page&pagesize=”.$MOD[pagesize].”&template=xxx-list&dtpre=$DT_PRE”)}–>
{/if}
