update two tables with one query in mysql PHPMyadmin? - php

Question

I have two tables, user_info and Friend_info. I want to do that when user update his record in user_info then it should also b update in friend_info where friend_id=user_id. I have tried this
UPDATE user_info (name, user_email, Gender, DOB, contact, address) WHERE user_id='$user_id',
friends_info(name, user_email, Gender, DOB, contact, address) WHERE friend_id='$user_id'
values('$name', '$user_email', '$Gender', '$DOB', '$contact', '$address');
But its not working . Any other solution please. It'll be appreciated.
I know this question is too late to ask now a days but its my problem because i am confused after doing so many search and no query is working in my case.

Answer 1

Your question is not clear. So are you testing something like you want query in phpmyadmin. if not then you might need to do in as a transaction. but if its a test or such try this:
UPDATE user_info (name, user_email, Gender, DOB, contact, address)
values('$name', '$user_email', '$Gender', '$DOB', '$contact', '$address')
WHERE user_id='$user_id';
UPDATE friends_info(name, user_email, Gender, DOB, contact, address)
values('$name', '$user_email', '$Gender', '$DOB', '$contact', '$address')
WHERE friend_id='$user_id';
So this is two query which then they are gonna execute together. But now in PHP

You can join the two tables in your statement using user_id as the joining key.
UPDATE user_info ui
INNER JOIN friends_info fi
ON ui.user_id = fi.user_id
SET ui.name = $name,
SET ui.user_email = $email,
SET ui.Gender = $Gender,
SET ui.DOB = $DOB,
SET ui.contact = $contact,
SET ui.address = $address,
-- set friends_info
SET fi.name = $name,
SET fi.user_email = $email,
SET fi.Gender = $Gender,
SET fi.DOB = $DOB,
SET fi.contact = $contact,
SET fi.address = $address
WHERE ui.user_id = $user_id;
