Multiple file upload in php
I want to upload multiple files and store them in a folder a开发者_JS百科nd get the path and store it in the database... Any good example you looked for doing multiple file upload...
Note: Files can be of any type...
Some further explanation might be useful for someone trying to upload multiple files. Here is what you need to do:
- Input name must be be defined as an array i.e.
name="inputName[]" - Input element must have
multiple="multiple"or justmultiple - In your PHP file use the syntax
"$_FILES['inputName']['param'][index]" - Make sure to look for empty file names and paths, the array might contain empty strings. Use
array_filter()before count.
Here is a down and dirty example (showing just relevant code)
HTML:
<input name="upload[]" type="file" multiple="multiple" />
PHP:
//$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
}
}
}
Multiple files can be selected and then uploaded using the
<input type='file' name='file[]' multiple>
The sample php script that does the uploading:
<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>
The selected files are received as an array with
$_FILES['file']['name'][0] storing the name of first file.
$_FILES['file']['name'][1] storing the name of second file.
and so on.
this simple script worked for me.
<?php
foreach($_FILES as $file){
//echo $file['name'];
echo $file['tmp_name'].'</br>';
move_uploaded_file($file['tmp_name'], "./uploads/".$file["name"]);
}
?>
HTML
create div with
id='dvFile';create a
button;onclickof that button calling functionadd_more()
JavaScript
function add_more() {
var txt = "<br><input type=\"file\" name=\"item_file[]\">";
document.getElementById("dvFile").innerHTML += txt;
}
PHP
if(count($_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
}
In this way you can add file/images, as many as required, and handle them through php script.
It's not that different from uploading one file - $_FILES is an array containing any and all uploaded files.
There's a chapter in the PHP manual: Uploading multiple files
If you want to enable multiple file uploads with easy selection on the user's end (selecting multiple files at once instead of filling in upload fields) take a look at SWFUpload. It works differently from a normal file upload form and requires Flash to work, though. SWFUpload was obsoleted along with Flash. Check the other, newer answers for the now-correct approach.

Simple is that, just count the files array first, then in while loop you can easily do this like
$count = count($_FILES{'item_file']['name']);
now you got total number of files right.
In while loop do like this:
$i = 0;
while($i<$count)
{
Upload one by one like we do normally
$i++;
}
Here is a function I wrote which returns a more understandable $_FILES array.
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 $_FILE;
}
I run foreach loop with error element, look like
foreach($_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";
}
}
Just came across the following solution:
http://www.mydailyhacks.org/2014/11/05/php-multifile-uploader-for-php-5-4-5-5/
it is a ready PHP Multi File Upload Script with an form where you can add multiple inputs and an AJAX progress bar. It should work directly after unpacking on the server...
We can easy to upload multiple files using php by using the below script.

<?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++)
{
move_uploaded_file($_FILES['property_images']['tmp_name'][$up],'../images/property_images/'.$_FILES['property_images']['name'][$up]);
}
}
This is what worked for me. I had to upload files, store filenames and I had additional inof from input fields to store as well and one record per multiple file names. I used serialize() then added that to the main sql query.
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 $e->getMessage();
}
}
}
extract($_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
{
$filename=basename($file_name,$ext);
$newFileName=$filename.time().".".$ext;
move_uploaded_file($file_tmp=$_FILES["files"]["tmp_name"][$key],"photo_gallery/".$txtGalleryName."/".$newFileName);
}
}
else
{
array_push($error,"$file_name, ");
}
}
and you must check your HTML code
<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>
