上傳的文件沒有保存在 php 的服務器中

Question

我正在嘗試上傳文件並將文件保存在服務器中，並通過 email 附加和發送文件。通過 email 附加和發送文件可以正常工作，文件沒有保存在服務器的上傳文件夾中。如何將文件保存在服務器中已經通過 email 作為附件發送.. 這是代碼

<form method="post" action="email-script.php" enctype="multipart/form-data" id="emailForm">
    <div class="form-group">
        <input type="text" name="name" id="name" class="form-control" placeholder="Name" >
       
    </div>
    <div class="form-group">
        <input type="email" name="email" id="email" class="form-control" placeholder="Email address" >
        
    </div>
    <div class="form-group">
        <input type="text" name="subject" id="subject" class="form-control"  placeholder="Subject" >
       
    </div>
    <div class="form-group">
        <textarea name="message" id="message" class="form-control" placeholder="Write your message here"></textarea>
      
    </div>
    <div class="form-group">
        <input type="file" name="attachment" id="attachment" class="form-control">
        <div id="attachmentError" style="color: red;font-size: 14px;display: none">attachmentError</div>
    </div>
    <div class="submit">
        <input type="submit" name="submit" onclick="return validateEmailSendForm();" class="btn btn-success" value="SUBMIT">
    </div>
</form>

Answer 1

上傳附件時是否收到任何錯誤/警告？

請嘗試在此語句之后調試代碼： if(!empty($_FILES["attachment"]["name"])){ ，就像天氣一樣，您正在 $_FILES 中獲取附件數據。

檢查上傳目錄是否為777（讀、寫、可執行）的權限，如果不是，則應授予該目錄的權限。

要檢查的另一件事是：php.ini 文件中的max_execution_time和upload_max_filesize ，增加它的值

取消鏈接 function 用於刪除服務器上的文件，您可以很好地刪除或注釋掉該部分。
