вы можете использовать continue; для управления циклом foreach:
foreach($_POST['tr_name'] as $tr_name) {
if(empty($tr_name)) { continue; }
$sql3 = "INSERT INTO trophies (game_name, tr_name, tr_description, tr_color, tr_ach_value) VALUES ('".$_POST['game_name']."', '".$tr_name['tr_name']."', '".$tr_name['tr_desc']."', '".$tr_name['tr_color']."', '".$tr_name['tr_ach_value']."')";
mysql_query($sql3);
}

Ваша форма будет генерировать 4 автономных массива, каждый из которых будет содержать 4 элемента, таких как имя, описание, цвет и т. Д. Это будет выглядеть так:
tr_name[0]
tr_desc[0]
tr_name[1]
tr_name[2]
...
Что вам, вероятно, нужно, так это один массив, содержащий 4 внутренних массива с 4 элементами в нем, например:
tr[0][name]
tr[0][desc]
tr[1][name]
tr[1][desc]
...

Ваш код PHP теперь должен выглядеть следующим образом:
// $_POST['tr'] holds an array with trophies and the trophies' attributes
foreach($_POST['tr'] as $tr) {
/*
$tr is now a hash like:
array(
"name" => "a name you entered",
"desc" => "the description",
"color" => "black",
"ach_value" => "a value you entered"
)
*/
if(empty($tr['name'])) { continue; }
$sql3 = "INSERT INTO trophies (game_name, tr_name, tr_description, tr_color, tr_ach_value) VALUES ('".$_POST['game_name']."', '".$tr['name']."', '".$tr['desc']."', '".$tr['color']."', '".$tr['ach_value']."')";
mysql_query($sql3);
}
