可以php / laravel批量更新（）

Question

Supposed I'm creating a bank management system. I want to make some of users' account activated. So I can...

$ids = [1, 2, 3];
User::where(function($enq) use($ids) {
    foreach ($ids as $id)
        $enq->orwhere('id', $id);
})->update(['activated'=>true]);

But how about making their money autoincrese $10 ?

    $ids = [1, 2, 3];
User::where(function($enq) use($ids) {
    foreach ($ids as $id)
        $enq->orwhere('id', $id);
})->update(function(){
    //what should I write here??? maybe I can write
    //$this_obj->money+=10;
});

The biggest problem is that, I can't get the "current object" inside the update(). My English is not very well, I hope my description won't confused anyone. And I hope to get a good solution. Thanks!

Answer 1

The query builder includes an increment method that could handle this:

User::whereIn('id', $ids)->increment('money', 10);

Note that I also used the whereIn method as a simple replacement of your loop of orwhere calls.

Answer 2

Laravel Eloquent Model provides increment method for incrementing a column's value by a given amount: https://github.com/laravel/framework/blob/5.4/src/Illuminate/Database/Eloquent/Model.php#L389 `

What you can do:

$ids = [1, 2, 3];
User::where(function($enq) use($ids) {
    foreach ($ids as $id)
        $enq->orwhere('id', $id);
})->increment('money', 10);

Or even better:

$ids = [1, 2, 3];
User::whereIn('id', $ids)
    ->increment('money', 10);
