PHP .doc 文件上傳不起作用

Question

我有一個頁面，我希望用戶能夠上傳 .pdf、.docx 和 .doc 文件。 PDF 和 DOCX 上傳工作正常，但不允許 DOC 文件。

這是我的表單和輸入按鈕：

<form action="?action=uploadForm" method="post" enctype="multipart/form-data" style="border:1px solid black;">
<input type="file" class="btn btn-md btn-primary btn-block" name="fileToUpload" id="fileToUpload" accept=".pdf,.docx,.doc" title="PDF and Word files only" />

對於 DOC 文件，該文件似乎永遠不會放入$_FILES 。

這是我所有的文件驗證/上傳邏輯：

if (isset($_GET['action']) == 'uploadForm') {
    // Get the option from the dropdown, so we can upload the form to the right directory
    $selectedTypeOfForm = $_POST['typeOfForm'];

    $target_dir = "files/" . $selectedTypeOfForm . "/";               // The directory for the upload to go to
    $target_file = $target_dir . basename($_FILES["fileToUpload"]["name"]);   // The name of the file being uploaded
    $fileName = basename($_FILES["fileToUpload"]["name"]);
    $uploadOk = 1;
    $fileType = pathinfo($target_file,PATHINFO_EXTENSION);

    dump($_FILES);

    $_SESSION['message'] .= "<br>";

    // Check if file already exists
    if (file_exists($target_file)) {
        $_SESSION['message'] .= "Sorry, the file <b>" . $fileName . "</b> already exists.<br>";
        $uploadOk = 0;
    }

    // Check file size
    if (($fileType == "pdf" && $_FILES["fileToUpload"]["size"] > MAXIMUM_PDF_SIZE) || ($fileType == "doc" && $_FILES["fileToUpload"]["size"] > MAXIMUM_WORD_SIZE) || ($fileType == "docx" && $_FILES["fileToUpload"]["size"] > MAXIMUM_WORD_SIZE)) {
        $_SESSION['message'] .= "Sorry, the file <b>" . $fileName . "</b> is too large. The file must be under ";

        if ($fileType == "pdf") {
            $_SESSION['message'] .= (MAXIMUM_PDF_SIZE / 1000000) . "MB for a PDF.<br>";
        } else {
            $_SESSION['message'] .= (MAXIMUM_WORD_SIZE / 1000000) . "MB for a Word document.<br>";
        }

        $uploadOk = 0;
    }

    // Allow certain file formats
    if($fileType != "pdf" && $fileType != "doc" && $fileType != "docx") {
        $_SESSION['message'] .= "Sorry, only PDF, DOC, and DOCX files are allowed. You tried to upload a <b>" . strtoupper($fileType) . "</b>.<br>";
        $uploadOk = 0;
    }

    // FINAL UPLOAD
    // Check if $uploadOk is set to 0 by an error
    if ($uploadOk == 0) {
        $_SESSION['message'] .= "<br>Sorry, your file <b>" . $fileName . "</b> was not uploaded.<br>";
    // if everything is ok, try to upload file
    } else {
        if (move_uploaded_file($_FILES["fileToUpload"]["tmp_name"], $target_file)) {
            $_SESSION['message'] .= "<br>The file <b>" . basename($_FILES["fileToUpload"]["name"]) . "</b> has been uploaded.<br>";
        } else {
            $_SESSION['message'] .= "<br>Sorry, there was an error uploading the file <b>" . $fileName . "</b>.<br>";
        }
    }

    // header('Location:/forms.php');
    echo "<a href='/forms.php'>FORMS</a>";
    exit;
}

上傳 .DOC 文件會顯示以下消息：

Sorry, the file already exists.
Sorry, only PDF, DOC, and DOCX files are allowed. You tried to upload a .

Sorry, your file was not uploaded.

問題在於 php.ini 中的upload_max_filesize和post_max_size 。 該文件在我的代碼觸及它之前就消失了，因為這些值被設置為低於我嘗試上傳的 .doc 文件的大小。
