Laravel add function to join - php

Question

I have 2 tables, a product table and a user table.
In my users table, there's a last_login column, which returns a datetime.
In this query, I'd like to be able to create a function that would allow me to only get products if the user hasn't been online for a certain amount of time.
I was thinking of using joins for this but I'm not overly familiar with them.
Something like...
$products = Product::where("price", "<=", $maxBudget)
->where('active', 1)
...
->join('users', function ($join) {
$join->on('products.created_by', '=', 'users.id')
->where('last_login', '>', 2592000);
})
->get()
except this wouldn't work because last_login is a datetime so I'd need to put in a function in there like:
if ($user->last_login->diffInSeconds(Carbon::now() > 2592000) {
do the thing
}
How could I do this?

If you're trying to join the tables then you should be able to do something like:
// min seconds
$threshold = 123456;
Product::query()
->join('users', 'products.created_by', '=', 'users.id')
->where('products.active', 1)
->where('users.last_login', '<=', now()->subSeconds($threshold)->toDateTimeString())
->select(['products.*', 'users.last_login'])
->get();
Otherwise if it's based on the logged in user's last_login:
// Get the user's last login attribute.
$lastLogin = auth()->user()->last_login;
// whatever the minimum time since their last login should be.
$threshold = 12345;
$exceeded = now()->diffInSeconds(Carbon::parse($lastLogin))->gte($threshold);
if ($exceeded) {
Product::where(...)->get();
}
