コードの解決策を見つけようとしています。ユーザーが index.php からテキスト ボックスに特定の数量を入力すると、その入力数量が Invoice.php に転送されるようにするにはどうすればよいですか。post メソッドを実行してみましたが、うまくいかないようです :/ いつものように、どんな助けや提案も大歓迎です! 私はそれが単純なものであることを願っています:(これが私のコードです:
このコードは製品配列を保持し、テキスト ボックスも含みます。
//The following arrays contain our products and their information, one product per array.
$hulkhamburger = array('Product' => 'Hulk Hamburger', 'Description' => '...', 'Price' => '$1.00', 'Quantity' => "<input type='text' name='quantity1'>");
$atomichotdog = array('Product' => 'Atomic Hot Dog', 'Description' => '...', 'Price' => '$2.00', 'Quantity' => "<input type='text' name='quantity2'>");
$friedchicken = array('Product' => 'Fantastic 4 Fried Chicken', 'Description' => '...', 'Price' => '$3.00', 'Quantity' => "<input type='text' name='quantity3'>");
$psyonicpizza = array('Product' => 'Psyonic Pizza', 'Description' => '...', 'Price' => '$4.00', 'Quantity' => "<input type='text' name='quantity4'>");
$marvelmeatloaf = array('Product' => 'Marvel Meatloaf', 'Description' => '...', 'Price' => '$5.00', 'Quantity' => "<input type='text' name='quantity5'>");
//The following array takes our previous five arrays and puts them into one array for easier coding and reading.
$allfood = array ($hulkhamburger, $atomichotdog, $friedchicken, $psyonicpizza, $marvelmeatloaf);
