我有2个嵌套表。父表行包含子表。如果需要，两个表都可以通过添加按钮添加行。父表值插入数据库中的product_size表，子表值插入product_color表中。父表包含大小，子表包含该大小的项目的颜色和数量。我想在父表行中插入子表值（颜色和数量）。表示父第一行子表值应仅插入父第一行，而父表第二行中的子表值应插入父第二行。目前，我的代码获取父表的所有行中的所有子表值，并在第一行中插入数据库中，然后再次从父表的所有行中获取所有子表值，并在数据库的第二行中插入父表。请检查我的代码，并帮助我指出代码中的问题所在。 / PHP CODE /

答案 0 :(得分：0)
好的，这只是一个仅针对颜色的子表进行更改的示例：
注意 - 我在jsbin中测试了javascript和html但没有确认/测试php
希望这有帮助！
