我想将图像与firstname,lastname相关联…如何检索最后一行并使用它来插入到其他表？我试过$image = $
mysqli-> insert_id;然后绑定,但它不工作.有人可以帮我吗？
$image = $MysqLi->insert_id;//this should come from table2 $stmt = $MysqLi->prepare(" insert into table1 (username,firstname,lastname,image) select ?,?,image from table2 t2 where username = ? and t2.id = ? "); $stmt->bind_param('sssss',$username,$fname,$lname,$image); $stmt->execute();
MysqLi :: $insert_id – MysqLi_insert_id – 返回上次查询中使用的自动生成的ID,示例：
$MysqLi = new MysqLi("localhost","my_user","my_password","world"); /* check connection */ if (MysqLi_connect_errno()) { printf("Connect Failed: %s\n",MysqLi_connect_error()); exit(); } $MysqLi->query("CREATE TABLE myCity LIKE City"); $query = "INSERT INTO myCity VALUES (NULL,'Stuttgart','DEU',617000)"; $MysqLi->query($query); printf ("New Record has id %d.\n",$MysqLi->insert_id); /* drop table */ $MysqLi->query("DROP TABLE myCity"); /* close connection */ $MysqLi->close();
产量
New Record has id 1.
