PHP Operational Database Issues
Problem:
There are two tables: Table1,table2
The fields in the Table1 are:
ID Title Content

The fields in the table2 are:
ID CID User

Where CID is the ID in table1

Table1 When you generate a data by insert into and write the ID in table1 to table2, how do you do that?

As follows:
Table1:
ID Title Content
1 Test Content
2 Test2 Content 2

Table2:
ID CID User
1 1 Users
2 2 users 2


Thank you ~



------Solution--------------------
MYSQL_INSERT_ID ();
Get the ID from the previous insert operation and insert the Table2
