文件上傳功能

-1

你好，我試圖與PHP文件上傳，所以我拷入它這個工作，但後來我wan't把這個在這樣的函數：文件上傳功能

function upload($file) { 
    $target_dir = "www/"; 
     $target_file = $target_dir . date("Y-m-d") . "_" . basename($file["name"]); 
     $uploadOk = 1; 
     $imageFileType = pathinfo($target_file, PATHINFO_EXTENSION); 

     $check = getimagesize($file["tmp_name"]); 
     if ($check !== false) { 
      echo "File is an image - " . $check["mime"] . "."; 
      $uploadOk = 1; 
     } else { 
      echo "File is not an image."; 
      $uploadOk = 0; 
     } 

    // Check if file already exists 
     if (file_exists($target_file)) { 
      echo "Sorry, file $target_file already exists."; 
      $uploadOk = 0; 
     } 
    // Check file size 
     if ($file["size"] > 500000) { 
      echo "Sorry, your file is too large."; 
      $uploadOk = 0; 
     } 
    // Allow certain file formats 
     if ($imageFileType != "jpg" && $imageFileType != "png" && $imageFileType != "jpeg" && $imageFileType != "gif") { 
      echo "Sorry, only JPG, JPEG, PNG & GIF files are allowed."; 
      $uploadOk = 0; 
     } 
    // Check if $uploadOk is set to 0 by an error 
     if ($uploadOk == 0) { 
      echo "Sorry, your file was not uploaded."; 
    // if everything is ok, try to upload file 
     } else { 
      if (move_uploaded_file($file["tmp_name"], $target_file)) { 
       echo "The file " . basename($file["name"]) . " has been uploaded."; 
      } else { 
       echo "Sorry, there was an error uploading your file."; 
      } 
     } 
     return $target_file; 
    }

，所以我可以這樣稱呼：

include 'upload.php'; 



    if(isset($_POST["send2"])) { 
     $p1=""; 
     $p2=""; 
     $p3=""; 
     $p4=""; 
     $p5=""; 

    if(isset($_FILES["p1"])){ 
     $p1= upload($_FILES["p1"]); 
    } 
     if(isset($_FILES["p2"])){ 
     $p2= upload($_FILES["p2"]); 
    } 
     if(isset($_FILES["p3"])){ 
     $p3=upload($_FILES["p3"]); 
    } 
     if(isset($_FILES["p4"])){ 
     $p4 = upload($_FILES["p4"]); 
    } 
     if(isset($_FILES["p5"])){ 
     $p5= upload($_FILES["p5"]); 
    } 

     $pcrud->create($_POST['titel'], $_POST['input'], "" . getdate() . "", $target_file, $_POST['p2'], $_POST['p3'], $_POST['p4'], $_POST['p5'], $_SESSION['user'], $ccrud->getidbytitle($_POST['cat'])); 
    }

但這不起作用的消息「文件名不能爲空」來了。我該如何解決這個問題有什麼問題？

「沒有工作」是一個廣泛的問題。究竟會發生什麼？ –

您嘗試上傳的文件夾是否具有寫入權限？ –

是的，它有。它工作時，我使用$ _Files ['nameoffile'] –

，我發現我不能，如果文件isset檢查問題，我必須檢查品牌的價值是這樣的：

這是我如何調用該函數：

if(isset($_POST["send2"])) { 
    $p1=""; 
     $p2=""; 
      $p3=""; 
      $p4=""; 
       $p5=""; 

if($_FILES["p1"]["name"]!=""){ 
    $p1= upload($_FILES["p1"]["name"],$_FILES["p1"]["tmp_name"],$_FILES["p1"]["size"]); 
} 
    if($_FILES["p2"]["name"]!=""){ 
    $p2= upload($_FILES["p2"]["name"],$_FILES["p2"]["tmp_name"],$_FILES["p2"]["size"]); 
} 
    if($_FILES["p3"]["name"]!=""){ 
    $p3=upload($_FILES["p3"]["name"],$_FILES["p3"]["tmp_name"],$_FILES["p3"]["size"]); 
} 
    if($_FILES["p4"]["name"]!=""){ 
    $p4 = upload($_FILES["p4"]["name"],$_FILES["p4"]["tmp_name"],$_FILES["p4"]["size"]); 
} 
    if($_FILES["p5"]["name"]!=""){ 
    $p5= upload($_FILES["p5"]["name"],$_FILES["p5"]["tmp_name"],$_FILES["p5"]["size"]); 
} 

    $pcrud->create($_POST['titel'], $_POST['input'], "" . getdate() . "", $p1, $p2, $p3, $p4, $p5, $_SESSION['user'], $ccrud->getidbytitle($_POST['cat'])); 
}

這是功能：

function upload($filename,$filetmpname,$size) { 
     $target_dir = "www/"; 
     $target_file = $target_dir . date("Y-m-d") . "_" . basename($filename); 
     $uploadOk = 1; 
     $imageFileType = pathinfo($target_file, PATHINFO_EXTENSION); 

     $check = getimagesize($filetmpname); 
     if ($check !== false) { 
      echo "File is an image - " . $check["mime"] . "."; 
      $uploadOk = 1; 
     } else { 
      echo "File is not an image."; 
      $uploadOk = 0; 
     } 

    // Check if file already exists 
     if (file_exists($target_file)) { 
      echo "Sorry, file $target_file already exists."; 
      $uploadOk = 0; 
     } 
    // Check file size 
     if ($size > 500000) { 
      echo "Sorry, your file is too large."; 
      $uploadOk = 0; 
     } 
    // Allow certain file formats 
     if ($imageFileType != "jpg" && $imageFileType != "png" && $imageFileType != "jpeg" && $imageFileType != "gif") { 
      echo "Sorry, only JPG, JPEG, PNG & GIF files are allowed."; 
      $uploadOk = 0; 
     } 
    // Check if $uploadOk is set to 0 by an error 
     if ($uploadOk == 0) { 
      echo "Sorry, your file was not uploaded."; 
    // if everything is ok, try to upload file 
     } else { 
      if (move_uploaded_file($filetmpname, $target_file)) { 
       echo "The file " . basename($filename) . " has been uploaded."; 
      } else { 
       echo "Sorry, there was an error uploading your file."; 
      } 
     } 
     return $target_file; 
    }
