MySQL if exists insert id else insert into two tables - mysql

Question

I've made the following SQL statement and it does not work and cannot figure out how to create a functioning one. Here is what i am trying to do.
Check if a value exists in a players table
If the value exists, i want to insert ignore into a roster table
If the value doesnt exist, i want to insert it into the players table and insert it into the roster table
Here is what i have
IF EXISTS (SELECT id AS plyrId FROM players WHERE email = #(:e) LIMIT 1)
BEGIN
INSERT IGNORE INTO roster
(date, teamId, playerId)
VALUES
( (:d), (:t), plyrId )
END
ELSE
BEGIN
INSERT INTO players
(status, date, first_name, last_name, email)
VALUES
( (:s), (:d), (:f), (:l), (:e) )
INSERT IGNORE INTO roster
(date, teamId, playerId)
VALUES
( (:d), (:t), LAST_INSERT_ID() ) //LAST_INSERT_ID() -> I want it to be pulled from the last id inserted from the players table - not sure how to accomplish this
END
Any help is appreciated!
ive tried another attemp without any luck either
IF (SELECT COUNT(*) FROM players WHERE email = (:e) > 0)
INSERT IGNORE INTO roster
(date, teamId, playerId)
(:d), (:t), SELECT id FROM players WHERE email =(:e)
ELSE
BEGIN
.. // havent got to this part yet. it follows the same logic as the one before
END

Answer 1

You must use trigger on event before insert
CREATE TRIGGER test_trigger BEFORE INSERT ON `players table` FOR EACH ROW SET
-- checking value exist or not, for each case write corresponding insert or inserts

Answer 2

This part of the query is highly suspect:
IF EXISTS (SELECT id AS plyrId FROM players WHERE email = #(:e) LIMIT 1)
BEGIN
INSERT IGNORE INTO roster
(date, teamId, playerId)
VALUES
( (:d), (:t), plyrId )
----------------------^
END
Unless you have a variable named plyrId, this will fail. Assigning an alias in a subquery does not define a variable in the outer query.
You can replace it with:
INSERT IGNORE INTO roster(date, teamId, playerId)
SELECT (:d), (:t), id
FROM players
WHERE email = #(:e)
LIMIT 1;
Or, you can change the if to:
IF EXISTS (SELECT plyrdId := id FROM players WHERE email = #(:e) LIMIT 1)
