在 php 中上传多个文件

我想上传多个文件，并存储在一个文件夹中，得到的路径，并存储在数据库中... 任何好的例子，你看做多个文件上传..。

注意: 文件可以是任何类型..。

这与上传一个文件没有什么不同—— $_FILES是一个包含所有上传文件的数组。

PHP 手册中有一章: 上传多个文件

如果您希望在用户端轻松地选择多个文件上传(一次选择多个文件而不是填写上传字段) ，请看一下 上传。它的工作方式不同于普通的文件上传表单，但是需要 Flash 才能工作。SWFUpload 与 Flash 一起被淘汰。检查其他更新的答案，找到现在正确的方法。

方法可以选择多个文件，然后上载
<input type='file' name='file[]' multiple>
执行上传的示例 php 脚本:

<html>
<title>Upload</title>
<?php
session_start();
$target=$_POST['directory'];
if($target[strlen($target)-1]!='/')
$target=$target.'/';
$count=0;
foreach ($_FILES['file']['name'] as $filename)
{
$temp=$target;
$tmp=$_FILES['file']['tmp_name'][$count];
$count=$count + 1;
$temp=$temp.basename($filename);
move_uploaded_file($tmp,$temp);
$temp='';
$tmp='';
}
header("location:../../views/upload.php");
?>
</html>

选定的文件作为数组接收

存储第一个文件名的 $_FILES['file']['name'][0]。
存储第二个文件名的 $_FILES['file']['name'][1]。
诸如此类。

我知道这是一篇老文章，但是一些进一步的解释可能会对那些试图上传多个文件的人有用... ... 以下是你需要做的:

  • 输入名称必须定义为数组，即。 name="inputName[]"
  • 输入元素必须有 multiple="multiple"或者只有 multiple
  • 在 PHP 文件中使用语法 "$_FILES['inputName']['param'][index]"
  • 确保寻找 < em > 空文件名和路径 ，数组可能包含 空字符串。在计数前使用 array_filter()。

下面是一个向下和肮脏的示例(仅显示相关代码)

HTML:

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

PHP:

//$files = array_filter($_FILES['upload']['name']); //something like that to be used before processing files.


// 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 file path
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


}
}
}

希望这个能帮上忙！

超文本标示语言

  1. 用 id='dvFile'创建 div;

  2. 创建一个 button;

  3. 该按钮的 onclick调用函数 add_more()

JavaScript

function  add_more() {
var txt = "<br><input type=\"file\" name=\"item_file[]\">";
document.getElementById("dvFile").innerHTML += txt;
}

PHP

if(count($_FILES["item_file"]['name'])>0)
{
//check if any file uploaded
$GLOBALS['msg'] = ""; //initiate the global message
for($j=0; $j < count($_FILES["item_file"]['name']); $j++)
{ //loop the uploaded file array
$filen = $_FILES["item_file"]['name']["$j"]; //file name
$path = 'uploads/'.$filen; //generate the destination path
if(move_uploaded_file($_FILES["item_file"]['tmp_name']["$j"],$path))
{
//upload the file
$GLOBALS['msg'] .= "File# ".($j+1)." ($filen) uploaded successfully<br>";
//Success message
}
}
}
else {
$GLOBALS['msg'] = "No files found to upload"; //No file upload message
}

通过这种方式，您可以添加文件/图像，需要多少就添加多少，并通过 php 脚本处理它们。

简单的是，只需要先计算文件数组，然后在 while 循环中，您可以很容易地这样做

$count = count($_FILES{'item_file']['name']);

现在你得到的文件总数是正确的。

在 while 循环中这样做:

$i = 0;
while($i<$count)
{
Upload one by one like we do normally
$i++;
}
小开

我使用错误元素运行 foreach 循环，如下所示

 foreach($_FILES['userfile']['error'] as $k=>$v)
{
$uploadfile = 'uploads/'. basename($_FILES['userfile']['name'][$k]);
if (move_uploaded_file($_FILES['userfile']['tmp_name'][$k], $uploadfile))
{
echo "File : ", $_FILES['userfile']['name'][$k] ," is valid, and was                      successfully uploaded.\n";
}


else
{
echo "Possible file : ", $_FILES['userfile']['name'][$k], " upload attack!\n";
}


}

下面是我写的一个函数，它返回一个更容易理解的 $_FILES数组。

function getMultiple_FILES() {
$_FILE = array();
foreach($_FILES as $name => $file) {
foreach($file as $property => $keys) {
foreach($keys as $key => $value) {
$_FILE[$name][$key][$property] = $value;
}
}
}
return $_FILE;
}

只是碰到了下面的解决方案:

Http://www.mydailyhacks.org/2014/11/05/php-multifile-uploader-for-php-5-4-5-5/

它是一个现成的 PHP 多文件上传脚本与一个表单，您可以添加多个输入和一个 AJAX 进度条。它应该在服务器上解包后直接工作..。

我们可以使用下面的脚本轻松地使用 php 上传多个文件。

下载完整源代码并预览

<?php
if (isset($_POST['submit'])) {
$j = 0; //Variable for indexing uploaded image


$target_path = "uploads/"; //Declaring Path for uploaded images
for ($i = 0; $i < count($_FILES['file']['name']); $i++) {//loop to get individual element from the array


$validextensions = array("jpeg", "jpg", "png");  //Extensions which are allowed
$ext = explode('.', basename($_FILES['file']['name'][$i]));//explode file name from dot(.)
$file_extension = end($ext); //store extensions in the variable


$target_path = $target_path . md5(uniqid()) . "." . $ext[count($ext) - 1];//set the target path with a new name of image
$j = $j + 1;//increment the number of uploaded images according to the files in array


if (($_FILES["file"]["size"][$i] < 100000) //Approx. 100kb files can be uploaded.
&& in_array($file_extension, $validextensions)) {
if (move_uploaded_file($_FILES['file']['tmp_name'][$i], $target_path)) {//if file moved to uploads folder
echo $j. ').<span id="noerror">Image uploaded successfully!.</span><br/><br/>';
} else {//if file was not moved.
echo $j. ').<span id="error">please try again!.</span><br/><br/>';
}
} else {//if file size and file type was incorrect.
echo $j. ').<span id="error">***Invalid file Size or Type***</span><br/><br/>';
}
}

$property_images = $_FILES['property_images']['name'];
if(!empty($property_images))
{
for($up=0;$up<count($property_images);$up++)

}

extract($_POST);
$error=array();
$extension=array("jpeg","jpg","png","gif");
foreach($_FILES["files"]["tmp_name"] as $key=>$tmp_name)
{
$file_name=$_FILES["files"]["name"][$key];
$file_tmp=$_FILES["files"]["tmp_name"][$key];
$ext=pathinfo($file_name,PATHINFO_EXTENSION);
if(in_array($ext,$extension))
{
if(!file_exists("photo_gallery/".$txtGalleryName."/".$file_name))

move_uploaded_file($file_tmp=$_FILES["files"]["tmp_name"][$key],"photo_gallery/".$txtGalleryName."/".$file_name);

}
}
else
{
array_push($error,"$file_name, ");
}
}

你必须检查你的 HTML 代码

<form action="create_photo_gallery.php" method="post" enctype="multipart/form-data">
<table width="100%">
<tr>
<td>Select Photo (one or multiple):</td>
<td><input type="file" name="files[]" multiple/></td>
</tr>
<tr>
<td colspan="2" align="center">Note: Supported image format: .jpeg, .jpg, .png, .gif</td>
</tr>
<tr>
<td colspan="2" align="center"><input type="submit" value="Create Gallery" id="selectedButton"/></td>
</tr>
</table>
</form>

这个简单的剧本对我很有用。

<?php


foreach($_FILES as $file){
//echo $file['name'];
echo $file['tmp_name'].'</br>';
move_uploaded_file($file['tmp_name'], "./uploads/".$file["name"]);
}


?>

我就是这么做的。我必须上传文件，存储文件名，我有额外的信息从输入字段存储以及一个记录每多个文件名。 然后我在主 sql 查询中添加了 seralize ()。

  class addReminder extends dbconn {
public function addNewReminder(){


$this->exdate = $_POST['exdate'];
$this->name = $_POST['name'];
$this->category = $_POST['category'];
$this->location = $_POST['location'];
$this->notes = $_POST['notes'];






try {


if(isset($_POST['submit'])){
$total = count($_FILES['fileUpload']['tmp_name']);
for($i=0;$i<$total;$i++){
$fileName = $_FILES['fileUpload']['name'][$i];
$ext = pathinfo($fileName, PATHINFO_EXTENSION);
$newFileName = md5(uniqid());
$fileDest = 'filesUploaded/'.$newFileName.'.'.$ext;
$justFileName = $newFileName.'.'.$ext;
if($ext === 'pdf' || 'jpeg' || 'JPG'){
move_uploaded_file($_FILES['fileUpload']['tmp_name'][$i], $fileDest);
$this->fileName = array($justFileName);
$this->encodedFileNames = serialize($this->fileName);
var_dump($this->encodedFileNames);
}else{
echo $fileName . ' Could not be uploaded. Pdfs and jpegs only please';
}
}


$sql = "INSERT INTO reminders (exdate, name, category, location, fileUpload, notes) VALUES (:exdate,:name,:category,:location,:fileName,:notes)";
$stmt = $this->connect()->prepare($sql);
$stmt->bindParam(':exdate', $this->exdate);
$stmt->bindParam(':name', $this->name);
$stmt->bindParam(':category', $this->category);
$stmt->bindParam(':location', $this->location);
$stmt->bindParam(':fileName', $this->encodedFileNames);
$stmt->bindParam(':notes', $this->notes);
$stmt->execute();
}


}catch(PDOException $e){
echo $e->getMessage();
}
}
}
