php中向多张表安插数据

Jun 13, 2016 pm 12:58 PM
deal nbsp order rem table

php中向多张表插入数据
表:order_table
    字段:order_id、(表:)rem_table.rem_id(主键)、order_number
表:deal_table
    字段:deal_id、order_id、deal_date、deal_information、deal_man

就向这两张表中插入数据,插入的数据有:order_number、deal_date、deal_information、deal_man

请问该咋办呀!其中在插入数据的时候,字段rem_table.rem_id不能为空,因为在以后查询数据时,要用的,(rem_table与order_table的查询)

------解决方案--------------------
先用If判断,然后再插入。

If()

   insert into () ;
   mysql->query();
   inser into ();
   mysql->query();

else
{
}
------解决方案--------------------
order表是deal表的"父亲"(根据你表的设计)
所以都是先有(插入)order再有(插入)deal
两种方案可选
1.都用数据库自增 ①插入order ②查询order_id ③插入deal
2.ID用PHP生成    ①插入order(把生成的ID直接写入) ②插入deal

用方法2的话 注意ID要有一定的复杂性,就像我们生成图片名一样 不能重复

From px to rem: The evolution and application of CSS layout units Introduction: In front-end development, we often need to use CSS to implement page layout. Over the past few years, CSS layout units have evolved and developed. Initially we used pixels (px) as the unit to set the size and position of elements.
