你看一下这个把,是数据库触发器,不是php触发器

用php的话可以这样

PHP code
class A{

  public function insertA(){
    //插入A表的代码
     
    [color=#FF0000]$this->insertB($a_id)[/color];
  }

  public function insertB($a_id){
    //插入B表的代码
  }
}
<br><font color="#e78608">------解决方案--------------------</font><br>用mysql 触发器<br>http://blog.csdn.net/mengxiangbaidu/article/details/7345108

php触发器这个不行,我是在学习,我想知道的是sql如何实现,3楼给我看的我找了一会儿好像找不到我想要的那个,也没有说明哦

------解决方案--------------------
mysql_query("insert into jf(id,name) values(null,'$name')",$conn) or die(mysql_error());
if($f){
$jf_id = mysql_insert_id();
mysql_query("INSERT INTO user (id,jf_id) VALUES (null,'$jf_id')",$conn) or die(mysql_error());
}

这样试试。
