[j4ymf]

hello all

 

im trying to get an array to work but i just cant do it.

my aim is, im running a fantasy football site and i don't want people to be able to add the same player in twice.

 

how would i go about doing it?

this is what i have and it dosen't work

 

many thanks j4ymf

 

 

function check_player_ids ($player_1, $player_2, $player_3, $player_4, $player_5, $player_6, $player_7, $player_8, $player_9, $player_10, $player_11) {

  //Put the players into an array
  $chosen_players = array($player_1, $player_2, $player_3, $player_4, $player_5, $player_6, $player_7, $player_8, $player_9, $player_10, $player_11);
    
  //Remove duplicates
  $unique_players = array_unique($chosen_players);
  
  //Compare the before and after to get any duplicates out
  $duplicate_players = array_diff($chosen_players, $unique_players);
  
  //Now check if there are any duplicates
  if (count($duplicate_players) > 0) {
global $bad_player;
$bad_player = $duplicate_players[0]; // only returns the first duplicate, but could be modified to return then all
return False;
  } else {
return True;
  }

}

Define what you mean by "it doesnt work". What is you function supposed to do? What are you trying to do?

Sorry i will try to explain

 

well im trying to check if the team has any duplicates,

 

so i have 11 players being entered,

but at the moment it lets the team through when you are entering it, even if i have two players the same.  so im trying to avoid terry being put in twice!!!

 

does that make sence

 

so im after the code to check if it has any duplicates in it,

 

thanks j4ymf
