onClick

this is just the form part of it.it checks all the boxes.
is document.checkfiles.checkbox[] right?
can it have the brackets in checkbox[] or the coding wrong?

echo '<form name="checkfiles" action="broken_files.php" method="POST" >';
$query = mysql_query("select id, title, thumbnail, file from games") or die(mysql_error());
while($row = mysql_fetch_array($query)) {
	if (!file_exists('../' . $row['thumbnail'])) {
		
	    echo $row['id'] . '';
	echo '
    <a href="manage_game.php?edit=' . $row['id'] . '">Edit</a>
	<input type="checkbox" name="checkbox[]" value="'.$row['id'].'">
<br />';

 
 }
	}
	 echo' 
	 <input type="submit" value="delete" />
	 <input type="button" name="CheckAll" value="Check All" onClick="checkAll(document.checkfiles.checkbox[])">
		
</form>';
