Question

我需要将图像上传到服务器并使用当前时间戳存储到PHP创建的目录中。下面是代码的相关部分，但没有按预期工作，它也没有创建文件夹，也没有打印到控制台。可能是什么问题？

修改

基于以下评论修改了php

upload.php的

  <?php 
//get unique id
$up_id = uniqid(); 
?>

<?php

//process the forms and upload the files
if ($_POST) {

//specify folder for file upload

$user = "user";


//console.log("debug.......");
 echo "debug.......";

if (!file_exists("/var/www/Scan")) {
    mkdir("/var/www/Scan", 0777, true);
}

$folderName = date("Y-m-d") . "_" . date("h_i_sa") . "_" . $user;
if (!file_exists("/var/www/Scan/$folderName")) {
    mkdir("/var/www/Scan/$folderName", 0777, true);
}

$folder = "/var/www/Scan/$folderName"; 

//specify redirect URL
$redirect = "upload.php?success";

//upload the file
move_uploaded_file($_FILES["file"]["tmp_name"], "$folder" . $_FILES["file"]["name"]);

//do whatever else needs to be done (insert information into database, etc...)

//redirect user
header('Location: '.$redirect); die;
}
//

?>

Answer 1

尝试一个简单的例子来理解：

<?php

//php content
if ($_POST) {   //here we are checking $_POST values that $_POST has some values. 

  //specify folder for file upload
  $tempDir = __DIR__ . DIRECTORY_SEPARATOR . 'upload'; //it means make a directory uploads where this php file is kept.
  if (!file_exists($tempDir)) { // if $tempDir is not there, so it will create that directory.
      mkdir($tempDir);
  }

  if(!empty($_FILES))//now checking your uploaded file is not empty
  {
      $nm=$_FILES['file']['name']; //here $nm get the name of the file 
      $tmp=$_FILES['file']['tmp_name'];//$tmp get the temporary file stored path 
      $mDir = __DIR__ . DIRECTORY_SEPARATOR . 'uploads'. DIRECTORY_SEPARATOR .time().$nm; //this your destination path with time+nameof file as a name of file.
      if(move_uploaded_file($tmp,$mDir)) //uploading file to your destination path, if uploaded then it will go in the if scope and echo.
      {
          echo "file uploaded with timestamp in uploads folder";
          //now redirect from here any where
      }
      else
      {
          echo "fail to upload a file";
      }
  }

}
?>

PHP里面创建文件夹（$ _POST）
