私が抱えている問題は、フォームが送信されたときにフィールドが欠落しているときに、「必要なフィールドのすべてを完了していません」と言ってから、フォームに戻るリンクを持っていることです。ただし、リンクはフォームに戻りますが、アドレスバーに参照が入力されていないため、フィールドが入力されていません

例: 最初のフォームのアドレス -

http://'192.168.1.251'/update.php?Reference=654321

フィールドが完成していない後に更新をクリックした後 -

http://'192.168.1.251'/update.php?Reference=.

以下に問題があるページのコードを次に示します: (update_ac.php)

SQL 更新は、クエリから true または false を返します。変更された行は返されません。更新後、変更された行を取得する必要があります。

$result=mysql_query("SELECT * FROM Triage WHERE Reference='$Reference'");
// and display result 
if($result){
    while($rows=mysql_fetch_array($result)){
        echo '<a href="update.php?Reference='.$rows['Reference'].' ">update test</a>';
    }
}

UPDATE ステートメントを使用して mysql からデータを取得しようとしています。UPDATE は 1 または 0 のみを返します。

引数、セッション、または Cookie を介して参照をスクリプトに渡す必要があります。データベースから取得することもできますが、SELECT ステートメントを使用する必要があります。

echo "<a href='update.php?Reference={$Reference}.'>update</a>\n";
