[英]PHP/MYSQL/Keys: Inserting Table into Two Tables Consistently
I have created these tables in phpmyadmin我在 phpmyadmin 中创建了这些表
food -->(id, user_id, name, price, description)
ingredient-->(id, name)
food_ingredient--> (id, food_id, ingredient_name)
I want food_id
to match with food.id same with ingredient_name
and ingredient.name
我希望food_id
与 food.id 匹配,与ingredient_name
名称和ingredient.name
名称相同
Anyways I want to insert data into food
and food_ingredient
at the same time when a user provides food.name
, food.price
, food.description
information.无论如何,当用户提供food.name
、 food.price
、 food.description
信息时,我想同时将数据插入到food
和food_ingredient
中。
So I have (after doing some stripping and trimming of user input):所以我有(在对用户输入进行了一些剥离和修剪之后):
INSERT INTO food
(id, user_id, name, price, description)
VALUES
(NULL,\"$user_id\", \"$name\",\"$price\",\"$food_desc\")"
The question is how do I get food_id
so that I can run something like:问题是我如何获得food_id
以便我可以运行类似的东西:
INSERT INTO food_ingredient
(id, food_id, ingredient_name)
VALUES
(NULL,\"$food_id\", \"$ingredient_name\")
Use the mysql_insert_id
function after the the first INSERT
and store the value in a variable that you can use in the related inserts.在第一个INSERT
之后使用mysql_insert_id
function 并将值存储在可以在相关插入中使用的变量中。
