v9如何在首頁顯示或排除某些欄目subcat(0,0,0,$siteid)

通過以下紅色部分的欄目id來控制顯示哪些欄目,id根據實際情況後台查詢，subcat函數看最後附件解釋，以下修改代碼：

V9顯示哪些欄目的方法

{loop subcat(0,0,0,$siteid) $r}
{if $r['catid']==1||$r['catid']==2 } //顯示哪些欄目
{php $num++}

{pc:content action="lists" catid="$r" order="updatetime DESC" thumb="1" num="1" return="info"}
{loop $info $v}

target="_blank" title="{$v["title']}"{title_style($v)}>{str_cut($v['title'],28)}
{str_cut($v['description'],100)}

{/loop}
{/pc}

{pc:content action="lists" catid="$r" num="5" order="id DESC" return="info"}

{loop $info $v}

• ·{str_cut($v['title'],40)}

{/loop}

{/pc}


{if $num%2==0}{/if}
{/if}
{/loop}

V9排除某個欄目的方法

{loop subcat(0,0,0,$siteid) $r}
{if $r['catid']==3 }{/if} //排除某個欄目
{php $num++}

{pc:content action="lists" catid="$r" order="updatetime DESC" thumb="1" num="1" return="info"}
{loop $info $v}

target="_blank" title="{$v["title']}"{title_style($v)}>{str_cut($v['title'],28)}
{str_cut($v['description'],100)}

{/loop}
{/pc}

{pc:content action="lists" catid="$r" num="5" order="id DESC" return="info"}

{loop $info $v}

• ·{str_cut($v['title'],40)}

{/loop}

{/pc}


{if $num%2==0}{/if}
{/loop}

=====================================================

{loop subcat(0,0,0,$siteid) $r}{/loop}函數解釋：

{loop subcat(0,0,0,$siteid) $r}{/loop}

/**

* 擷取子欄目
* @param $parentid 父級id
* @param $type 欄目類型 1為單網頁類型，0為欄目類型；（查看phpcms的mysql資料庫可以看到）
* @param $self 是否包含本身 0為不包含
* @param $siteid 網站id
*/
function subcat($parentid = NULL, $type = NULL,$self = '0', $siteid = '') {
if (empty($siteid)) $siteid = get_siteid();
$category = getcache('category_content_'.$siteid,'commons');
foreach($category as $id=>$cat) {
if($cat['siteid'] == $siteid && ($parentid === NULL || $cat['parentid'] == $parentid) && ($type === NULL || $cat['type'] == $type)) $subcat[$id] = $cat;
if($self == 1 && $cat['catid'] == $parentid && !$cat['child']) $subcat[$id] = $cat;
}
return $subcat;
}
