dedeCMS常用功能板块记忆
1、自动调到栏目第一个子栏目
<script> {dede:channel type='son' row='1'} window.location.href='[field:typelink /]'; {/dede:channel} </script>
2、三级栏目判断示例
{dede:php}
$parentId = $refObj->Fields["topid"];
//判断是否是三级栏目
$row = $dsql->GetOne("select * from dede_arctype where id=".$parentId);
if($row['topid'] != 0){
//有三级栏目
$topid = $row['topid'];
}else{
$topid = $parentId;
}
$dsql->SetQuery('select * from dede_arctype where topid='.$topid);
$dsql->Execute();
$rowNum = $dsql->GetTotalRow();
//var_dump($rowNum);
if($rowNum > 1){
echo '<div class="h_sgbk">';
}else{
echo '<div class="h_sgbk" style="display: none;">';
}
{/dede:php}
3、首页判断
<a {dede:field name=typeid runphp="yes"}(@me=="")? @me=" class='hover'":@me="";{/dede:field} href="/">网站首页</a>
4、判断是否是文章页面
if(isset($refObj->Fields['litpic'])) //有很多属性,随便判断一个
5、调用自定义banner图
{dede:php}
$id = 9;
$sql = "select imgstring from dede_banner where id = ".$id;
$imgString = $dsql->GetOne("$sql");
$imgArr = json_decode($imgString['imgstring']);
$result = "";
foreach($imgArr as $key=>$value){
$result .= '<div class="swiper-slide"><img src="'.$cfg_custom_banner_upload_dir.'/'.$value.'"></div>';
}
echo $result;
{/dede:php}
