Laravel has in-built increment() and decrement() functions to increase or decrease a value of the column, by 1 or with the given number. Below are the examples:
|
1 |
User::find($user_id)->increment('post_count'); |
That’s it – it will actually run update column + 1 under the hood.
You can specify a second parameter to this function, the amount of incrementing. The default is 1, but it can be any other number:
|
1 |
User::find($user_id)->increment('post_count', 50); |
The same way, we can use decrement() function:
|
1 |
User::find($user_id)->decrement('post_count', 50); |
