Question

When i add a new from my custom CMS, i need to add some diferent info about this post at 2 different tables.

So the first table is DATA and the Second is SEO.

I have looked around but i haven't found what i wanted.

Answer 1

It's tricky without any more information but I'd guess you're looking for mysql_insert_id()

$sql = 'INSERT INTO table (col) VALUES (1)';
mysql_query($sql);

$inserted_id = mysql_insert_id();

// Run your next query

Answer 2

assuming you are using msysql and the first table has autoincrement id, then you can use

$id = mysql_insert_id() 

to get the id after the first insert, then use that id in the 2nd insert
