# onPlayerCommand (Server)

> Fired when a player sends a command to the server, before it runs. Cancelling the event stops the command.

- **Platform**: MY Multiplayer (MYMP)
- **Kind**: Lua Event
- **Side**: Server
- **Category**: Keyboard
- **Cancellable**: `cancelEvent`
- **URL**: https://wiki.mymp.gg/en/onPlayerCommand

## Syntax

```lua
addEventHandler("onPlayerCommand", root, function(string command) ... end)
```

## Handler parameters

| Name | Type | Description |
| --- | --- | --- |
| `command` | `string` | The command's name, without its arguments. |

## Source

The player who sent the command.

The client sends the server the commands no client script handled and the ones only the server runs, such as the resource commands. `executeCommandHandler` does not fire this event.

## Example

```lua
local lastCommand = {}

addEventHandler("onPlayerCommand", root, function(command)
    local now = getTickCount()
    if lastCommand[source] and now - lastCommand[source] < 500 then
        cancelEvent()
        return
    end
    lastCommand[source] = now
end)
```
