POKER GAME: Process a Checkbox array?

POKER GAME: Process a Checkbox array?

Hello!

I'm norwegian, sorry about my english

My dillemma is that I have a 5 card poker game where I want to check the cards I want to keep. And then submit it and get some new cards.

$("img#card").toggle(function () {
       $(this).addClass("show");
       $('input[name=card[]]').attr('checked', true);

     },function () {
       $(this).removeClass("show");
       $('input[name=card[]]').attr('checked', false);

     });

This code is my jquery.
<input type="checkbox" name="card[]" value="a" id="card1" class="checkbox" />
   <img src="Kort/10-s.png" alt="Spar 2-er" id="card" title="Spar 2-er" />
      
   <input type="checkbox" name="kort[]" value="c" id="card2" class="checkbox" />
   <img src="Kort/10-s.png" alt="Spar 2-er" id="card" title="Spar 2-er" />

This is the HTML

<?php

if (isset($_POST['submit'])){
   echo $_POST['card'][0];
}

?>

This is the PHP

Now my problem: I can't use the card[] array in the jquery code.
How can I fix this?

Thanks for answers!
