我創建了一些代碼，允許用戶在 MySQL 數據庫中上傳一些圖像。這是我的兩個問題：當發生錯誤時，例如因為文件不是圖像，有問題的文件不會被加載，但其他文件會加載。相反，我希望即使只是發生錯誤，也不會上傳任何文件。示例：如果我上傳 3 個文件，其中 1 個不是圖片：我現在不想要的輸出：File 1 uploaded
File 2 uploaded
Just JPG and PNG images are allowed // file 3 not uploaded我期望擁有：No files uploaded // Even if a single file is not good, nobody gets uploaded如果我上傳n 個文件，將打印n 條消息。例如，如果我上傳 3 個文件，輸出將是：File 1.png upload correctly
File 2.png upload correctly
File 3.png upload correctlyBut what I hope to have only one sentence, like 3 files uploaded.這是我的代碼：$timestamp = time();$total = count($_FILES[ 'upload' ][ 'name' ]); if ($total==0) { echo "Please upload at least one file"; $uploadOk = 0; } else { $tmpFilePath = $_FILES['upload']['tmp_name'][$i]; for($i = 0; $i < $total; $i++) { if ($tmpFilePath != '') { $newFilePath = "./uploadFiles/" . $_FILES['upload']['name'][$i]; $completeFileName = basename($_FILES["upload"]["name"][$i]); $target_file = "uploads/$completeFileName"; $uploadOk = 1; $estensione = strtolower(pathinfo($target_file, PATHINFO_EXTENSION)); $Name = basename($_FILES["upload"]["name"][$i]); if($extension != 'jpg' && $extension != 'png') { echo "Only JPG and PNG files are allowed"; $uploadOk = 0; }
