MySql split rows

Dear community,
I have to split string in table and list all values. I'll skip the code and jump directly to mysql query.

This is the table:
Code:
category     title
=======     =======
7,3         title 1
1,3         title 2
1,2,3       title 3

Now, what I need is split category into single value like:
Code:
category     title
=======     =======
7           title 1
3           title 1
1           title 2
3           title 2
1           title 3
2           title 3
3           title 3

I tried with the "classic" function SPLIT_STR:
Code:
CREATE FUNCTION SPLIT_STR(
  x VARCHAR(255),
  delim VARCHAR(12),
  pos INT
)
RETURNS VARCHAR(255)
RETURN REPLACE(SUBSTRING(SUBSTRING_INDEX(x, delim, pos),
       LENGTH(SUBSTRING_INDEX(x, delim, pos -1)) + 1),
       delim, '');

And then the query:
Code:
SELECT SPLIT_STR(category, ',', 1), title
FROM `post`

But in this case I got only the first value of each row.

Could someone advise?

Thanks
Lucas
