Question

我有一个HTML表单+ PHP脚本来上传保留原始名称的单个图像。我想将此脚本从单个图像转换为多个图像，并保留每个图像的原始名称。

这是我的HTML代码：

    <form action="upload.php" method="post" enctype="multipart/form-data">
    <input type="file" name="userfile"/>
    <input type="text" name="imgdec">
    <button name="upload" type="submit" value="Submit">
</form>

这是我的PHP代码：

    <?php


if(isset($_POST['upload'])) {

$allowed_filetypes = array('.jpg','.jpeg','.png','.gif');
$max_filesize = 10485760;
$upload_path = 'uploads/';
$description = $_POST['imgdesc'];

$filename = $_FILES['userfile']['name'];
$ext = substr($filename, strpos($filename,'.'), strlen($filename)-1);

if(!in_array($ext,$allowed_filetypes))
  die('The file you attempted to upload is not allowed.');

if(filesize($_FILES['userfile']['tmp_name']) > $max_filesize)
  die('The file you attempted to upload is too large.');

if(!is_writable($upload_path))
  die('You cannot upload to the specified directory, please CHMOD it to 777.');

if(move_uploaded_file($_FILES['userfile']['tmp_name'],$upload_path . $filename)) {
   $query = "INSERT INTO uploads (name, description) VALUES ($filename, $description)"; 
   mysql_query($query);

echo 'Your file upload was successful!';


} else {
     echo 'There was an error during the file upload.  Please try again.';
}
}


?>

我知道这是一篇旧帖子，但对于试图上传多个文件的人来说，一些进一步的解释可能会有用......这就是你需要做的事情：

输入名称必须定义为数组，即name =“inputName []”
输入元素必须具有多个=“多个”或多个
在PHP文件中使用语法 “$ _FILES [ 'inputName'] [ 'PARAM'] [指数]”
确保查找空文件名和路径，数组可能为包含空字符串

这是一个肮脏的例子（仅显示相关代码）

HTML：

<input name="upload[]" type="file" multiple="multiple" />

PHP：

// Count # of uploaded files in array
$total = count($_FILES['upload']['name']);

// Loop through each file
for($i=0; $i<$total; $i++) {
  //Get the temp file path
  $tmpFilePath = $_FILES['upload']['tmp_name'][$i];

  //Make sure we have a filepath
  if ($tmpFilePath != ""){
    //Setup our new file path
    $newFilePath = "./uploadFiles/" . $_FILES['upload']['name'][$i];

    //Upload the file into the temp dir
    if(move_uploaded_file($tmpFilePath, $newFilePath)) {

      //Handle other code here

    }
  }
}

希望这会有所帮助！
