织梦判断栏目是否有栏目图片,如果没有的话就显示栏目名称


用以下代码实现:

{dede:field.typeid runphp='yes'} 
$ID = @me; 
$sql = "SELECT * FROM `dede_arctype` WHERE id=$ID"; 
$query = mysql_query($sql); 
$row=mysql_fetch_array($query); 
$arcpic = "$row[arcpic]"; 
$typename = "$row[typename]"; 
if($arcpic == null) 
@me = '<div><h1>'.$typename.'</h1></div>'; 
 else @me = '<img src="'.$arcpic.'" width="100%" border="0" />';  
{/dede:field.typeid}
