php - 使用多文件 uploader 只上传一个文件

Question

下面的 PHP 文件脚本只上传一个文件，尽管它应该发送多个文件。看不懂哪里断了。尝试使用 foreach 但无济于事。

我做了一个var_dump，它们显示了正确的发送文件数。

HTML

<form id="fileupload" method="POST" enctype="multipart/form-data">
    <input type="file" name="uploadfile[]" multiple id="uploadfile" />
</form>

PHP

<?php

require_once 'config.php';

############ Edit settings ##############
$UploadDirectory    = './storage/';
#########################################


if(!isset($_FILES["uploadfile"])) {
    die('Something wrong with upload! Is "upload_max_filesize" set correctly?');
}

//check if this is an ajax request
if (!isset($_SERVER['HTTP_X_REQUESTED_WITH'])){
    die();
}


// Total number of files to be uploaded
$total_files = count($_FILES['uploadfile']['name']);

//check if there is at least 1 file
if($total_files < 1) {
    die();
}


for($i=0; $i<$total_files; $i++) {
    //Is file size is less than allowed size.
    if ($_FILES["uploadfile"]["size"][$i] > 29000000) {
        die("File size is too big!");
    }

    $allowedTypes = array('gif', 'png', 'jpeg', 'jpg', 'pdf', 'xls', 'xlsx', 'doc', 'docx', 'ppt', 'pptx', 'mp3', 'mp4', 'rar', 'zip', 'txt');

    $FileNameFull       = strtolower($_FILES['uploadfile']['name'][$i]);
    $FileNameShort      = pathinfo($FileNameFull, PATHINFO_FILENAME);
    $FileExt            = pathinfo($FileNameFull, PATHINFO_EXTENSION);

    if(!in_array($FileExt, $allowedTypes)) {
        die('Unsupported File format!');
    }

    $FileCode      = rand(0, 9999999999); //Random number to be used to rename actual filename
    $NewFileName        = $FileCode.'.'.$FileExt; //new file name

    if(move_uploaded_file($_FILES['uploadfile']['tmp_name'][$i], $UploadDirectory.$NewFileName )) {
        // Save the file details to database
        //$query = $dbh->prepare("INSERT INTO uploads(file_name, file_code, file_ext, timestamps) VALUES (:file_name, :file_code, :file_ext, :timestamps)");
        /*$query->execute(array(
            ":file_name" => $FileNameShort,
            ":file_code" => $FileCode,
            ":file_ext" => $FileExt,
            ":timestamps" => round(microtime(true) * 1000)
        ));*/

        die('Success! File Uploaded.');
    }
    else{
        die('error uploading File!');
    }

}

好吧，我给你举个小例子:

HTML:

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

PHP:

$totalImage = count($_FILES['uploadfile']['name']);

for($i=0; $i<$totalImage; $i++) {
  $temporaryPathOfImage = $_FILES['uploadfile']['tmp_name'][$i];

  if ($temporaryPathOfImage != ""){
    $dirPath = "./storage/" . $_FILES['uploadfile']['name'][$i];

    if(move_uploaded_file($temporaryPathOfImage, $dirPath)) {
      //Code Here
    }
  }
}

问题:

die('Success! File Uploaded.');

删除此行，以便您将获得该循环中的所有图像。
