You can always add a command to see if it can attach the vehicle. If your vehicles have any ID linked to them you can do it like;

• user uses a command with an ID
  
• check if the vehicle with the ID is close and the user is in a vehicle.
  
• attach them.

Why not but the player must do the command for attach the trailer, right ?

I have tried to make my own script for attach/detach trailer from a vehicle.

i can detach the trailer like that:

addEventHandler("[color=#BFBFFF]onPlayerLogin[/color]", root, 
   [color=#0000FF]function()[/color] 
       bindKey(source, "[color=#BFBFFF]o[/color]", "[color=#BFBFFF]up[/color]", unhookTrailer) 
    [color=#0000FF]end[/color] 
) 
  
addEventHandler("[color=#BFBFFF]onResourceStart[/color]", resourceRoot, 
   [color=#0000FF]function()[/color] 
       for _, v in ipairs(getElementsByType("[color=#BFBFFF]player[/color]")) do 
           bindKey(v, "[color=#BFBFFF]o[/color]", "[color=#BFBFFF]up[/color]", unhookTrailer) 
        [color=#0000FF]end[/color] 
    [color=#0000FF]end[/color] 
) 
  
[color=#0000FF]function[/color] unhookTrailer(thePlayer, commandName) 
   [color=#0000FF]if[/color] isPedInVehicle(thePlayer) [color=#0000FF]then[/color] 
      [color=#0000FF]local[/color] theVehicle = getPedOccupiedVehicle(thePlayer) 
      [color=#0000FF]local[/color] success = detachTrailerFromVehicle(theVehicle) 
      [color=#0000FF]local[/color] x, y, z = getElementPosition(theVehicle) 
      [color=#0000FF]if[/color] (success) [color=#0000FF]then[/color] 
          [color=#0000FF]if[/color] getElementType("[color=#BFBFFF]trailer[/color]") [color=#0000FF]then[/color] 
             setElementPosition(trailer, x+2, y, z) 
          [color=#0000FF]end[/color] 
             outputChatBox("[color=#BFBFFF]Trailer detached![/color]", thePlayer) 
      [color=#0000FF]else[/color] 
             outputChatBox("[color=#BFBFFF]Trailer not attatched[/color].", thePlayer) 
      [color=#0000FF]end[/color] 
    [color=#0000FF]end[/color] 
[color=#0000FF]end[/color] 
addCommandHandler("[color=#BFBFBF]unhook[/color]", unhookTrailer) 

is someone able to help me to make the attach function ?
