私の最後の質問は私の問題が半分解決されたので閉じられたので、もう一度質問します。MySQL レコードを更新するためにフォームを送信すると、すべてのフィールドに入力しないと構文エラーが発生しました。すべてのフィールドに入力せずにフォームがレコードを更新できるようにする解決策が与えられましたが、フィールドに投稿されたデータを渡す代わりに、すべてのフォーム投稿がデータベースのすべてのフィールドで番号1です. これに対する解決策は何ですか?

コードの問題は、AND代わりに を使用していることです&&

ただし、isset()は冗長であるため、 への呼び出しを削除するときに && はまったく必要ありませんisset()。例:

// section 1 column 5 row 1 - 5 //
$part_price1=!empty($_POST['part_price1'])? $_POST['part_price1'] : '';
$part_price2=!empty($_POST['part_price2'])? $_POST['part_price2'] : '';
$part_price3=!empty($_POST['part_price3'])? $_POST['part_price3'] : '';
$part_price4=!empty($_POST['part_price4'])? $_POST['part_price4'] : '';
$part_price5=!empty($_POST['part_price5'])? $_POST['part_price5'] : '';

// section 1 column 6 row 1 - 5 //
$price_extension1=!empty($_POST['price_extension1'])? $_POST['price_extension1'] : '';
$price_extension2=!empty($_POST['price_extension2'])? $_POST['price_extension2'] : '';
$price_extension3=!empty($_POST['price_extension3'])? $_POST['price_extension3'] : '';
$price_extension4=!empty($_POST['price_extension4'])? $_POST['price_extension4'] : '';
$price_extension5=!empty($_POST['price_extension5'])? $_POST['price_extension5'] : '';

コメントで述べたように、isset()知りたいのが空でない値を持っているかどうかである場合、への呼び出しは必要ありません。
