Question

我在Ubuntu上。我正在尝试上传小图像的用户文件。我检查了$ _FILES，它充满了数据。我尝试调试move命令，但它没有回应任何东西。

if ($_SERVER['REQUEST_METHOD'] == 'POST' ){
    //Now handle everything
    if(isset($_POST["submit"])) {
        print_r($_FILES);
        //Store the image
        if(!empty($_FILES['uploaded_file']))
        {
          $path = "/neel/public/img/";
          $path = $path.basename($_FILES['uploaded_file']['name']);
          if(move_uploaded_file($_FILES['uploaded_file']['tmp_name'], $path)) {

            echo 'Its working';
          } else{
              echo 'I am done!!!';
              die();
          }
        } 
    createnewEvent($conn);
    header('Location:/neel/index.php');
    }
}

Answer 1

您可以通过检查文件的名称来检查文件是否存在。

if(!empty($_FILES['file']['name']))

其中file是文件输入字段的名称。

Answer 2

如果$ _SERVER ['REQUEST_METHOD']不是“POST”，那么您显示的脚本只会“不回显任何内容”。假设您对事件的描述是准确的，那么问题的形式是@halojoy要求您在此处显示。

我希望你不要将脚本重定向回自身。此外，您不应该在回声后尝试重定向。

Answer 3

P上。上面的G是正确的。
而不是检查，如果$ _POST ['submit']
你应该检查一下：
if(isset($_FILES['uploaded_file']['name']))
