まとめているサイトに問題があります。
問題が何であるかは理解していますが、修正方法がわかりません。
私が持っているのはプロフィールサイトで、サイトに写真を追加しています。
ここで、プロファイルの編集に入るときに、プロファイルの画像を指定しない場合、$ FILE []配列は空であるため、データベースに空白の値が入力され、基本的に写真が削除されます。
私は次のようなことをしたい：
if $uploadfile = " " DO NOT WRITE ANYTHING TO THE DB.
ご存知のとおり、$ uploadfile = $ _FILES ['upload'] ['tmp_name'];
私のコードは次のようになります：
if (isset($_POST['action']) and $_POST['action'] == 'upload')
{
$uploadfile = $_FILES['upload']['tmp_name'];
$uploadname = $_FILES['upload']['name'];
$uploadtype = $_FILES['upload']['type'];
$uploaddata = file_get_contents($uploadfile);
}
そして編集コードはこのように見えます
// EDIT A PLAYER PROFILE
if (isset($_POST['action']) and $_POST['action'] == 'Edit' )
{
include $_SERVER['DOCUMENT_ROOT'] . '/includes/db.inc.php';
try
{
// $sql = 'SELECT id, name, age, position, height, weight, satscore, gpa FROM player WHERE id = :id';
