{dede:sql sql="SELECT * FROM `dede_arctype` AS t1 JOIN (SELECT ROUND(RAND() * ((SELECT MAX(id) FROM `dede_arctype`)-(SELECT MIN(id) FROM `dede_arctype`))+(SELECT MIN(id) FROM `dede_arctype`)) AS id) AS t2 WHERE t1.id >= t2.id ORDER BY t1.id LIMIT 1"}

{/dede:sql}
最后limit 1 改成多條調(diào)用。
[field:typedir function='str_replace("{cmspath}","",@me)'/]
由于隨機調(diào)用非常占用CPU不建議大家使用
