solved it with this:

PHP код:

SetTimerEx("AttachTrailer", 1000, 0, "i", playerid); 


PHP код:

function AttachTrailer(playerid)
 {
     new Float:pX, Float:pY, Float:pZ;
    GetPlayerPos(playerid,pX,pY,pZ);
    new Float:vX, Float:vY, Float:vZ;
    GetVehiclePos(TrailerID[playerid],vX,vY,vZ);
    if((floatabs(pX-vX)<100.0)&&(floatabs(pY-vY)<100.0)&&(floatabs(pZ-vZ)<100.0)&&(TrailerID[playerid]!=GetPlayerVehicleID(playerid)))  AttachTrailerToVehicle(TrailerID[playerid],GetPlayerVehicleID(playerid));
    return 1;
}
