Question

I’m using PHP, AJAX with jQuery so when this if statment process it will show all the players that have been selected along with placing a remove button and a onclick="removeplayer(test);". But when I click the “Remove player” button I will either get a null or undefined.

PHP

   if(count($_SESSION['players'],COUNT_RECURSIVE) == $_SESSION['savedPlayers'] )
{

    foreach($_SESSION['players'] as $key => $value){
    echo "Player #:  . $key . ; Player Name: . $value . \n";
    echo "<input type=\"button\" name=\"" . $key . " \" id=\"" .  $value . "  \" value=\"Remove\" onclick=\"removePlayer(" . $value . ");\"> <br />";
    }

    echo "Max number of Players";
}

And my JavaScript is basic now because I’m just trying to make sure I’m getting the id passed correctly. I eventually will add jQuery that will remove the player from the list.

Here is my JavaScript:

function removePlayer(test){    

    alert(test);
    };

Its because that you have not enclosed the $value within quotes try this

echo "<input type=\"button\" name=\"" . $key . " \" id=\"" .  $value . "  \" value=\"Remove\" onclick=\"removePlayer('" . $value . "');\"> <br />";
