I do have a folder named uploads in my root but still this wont work, i dont even get the error. Getting tired..Whats wrong?

You might be better off doing something like:
if (isset($_FILES['userfile'))
In your current code, do you know whether the lines within the "if (count($_POST))" block actually execute? The first thing I would've done is shoved a print_r call (or even just echoed some text) into both the if block and created an else block with an echo statement.
It just means you know what it's trying to do, and where it's failing, rather than trying to make guesses at it.

how to upload multiple images on a website using php

I am trying to upload multiple images on my website when user clicks on upload button. I was able to do that for one image, but I am not sure how to do for multiple images.
My code:
index.php
<html>
<head></head>
<body>
<form action="backend.php" method="POST" enctype="multipart/form-data">
<input type="file" name="file" >
<button type="submit" name="submit">button</button>
</form>
</body>
</html>
database.php
<?php
if (isset($_POST['submit'])) {
$file = $_FILES['file'];
$fileName = $_FILES['file']['name'];
$fileTmpName = $_FILES['file']['tmp_name'];
$fileSize = $_FILES['file']['size'];
$fileError = $_FILES['file']['error'];
$fileType = $_FILES['file']['type'];
$fileExt = explode('.', $fileName);
$fileActualExt = strtolower(end($fileExt));
$allowed = array('jpg', 'jpeg', 'png', 'pdf');
if (in_array($fileActualExt, $allowed)) {
if($fileError === 0) {
if ($fileSize < 10000000) {
$fileNameNew = uniqid('', true).".".$fileActualExt;
$fileDestination = 'uploads/'.$fileNameNew;
move_uploaded_file($fileTmpName, $fileDestination);
header("Location: index.php?uploadsuccess");
} else {
echo "Your file is too big!";
}
} else {
echo "There was an error uploading your file";
}
} else {
echo "You cannot upload files of this type!";
}
}
?>
I changed a bit in my code (index.html) so I can at least select multiple images: <input type="file" name="file[]" multiple>
but when I do that and click on upload it says:
Warning: explode() expects parameter 2 to be string, array given in /opt/lampp/htdocs/testing/backend.php on line 11
Warning: end() expects parameter 1 to be array, null given in /opt/lampp/htdocs/testing/backend.php on line 12
You cannot upload files of this type!
I assume cause it expects it to be string but I have an array now. How can I make my code work in database.php for multiple files? It works for single image, but not for multiple. If someone can reckon something?
Ok, let's say you have this HTML:
<form action="backend.php" method="POST" enctype="multipart/form-data">
<input type="file" name="file[]" multiple />
<button type="submit" name="submit">button</button>
</form>
Normally (without multiple and with name="file"), your PHP would receive something like this:
$_FILES['file']['name'] // contains the file name
However, sending multiple files, your PHP will receive these files as following:
$_FILES['file']['name'][0] // contains the first file name
$_FILES['file']['name'][1] // contains the second file name
// ...

if anyones curious heres my html for the upload page
<!DOCTYPE html>
<html>
<head>
<title>Upload a Book</title>
<link href = "style2.css" type = "text/css" rel = "stylesheet" />
</head>
<body>
<form action="upload.php" method="post" enctype="multipart/form-data">
Name: <input type="text" name="name" required/>
Type: <input type="text" name="type" required/>
File: <input type="file" name="file" required/>
<input type="submit" value="Upload" />
</form>
</body>
</html>
Firstly...
Don't upload files directly in your site! You should upload them with an API, outside, in a cloud storage. In this case, you can use Cloudinary . So, you don't need to think much about the files uploaded. Again, you can show them easily!
Don't store information like names and others(without the file) in a text file. Storing them in a MySQL database is the best way to do so.
Secondly...
Use different inputs for collecting book names and other information so that, you can display and modify them easily.
Thirdly...
Please give the code you are using for displaying data
I'm a Homo sapiens So I can write anything wrong. Please forgive me for that.

Warning: Invalid argument supplied for foreach() - uploading photos form

Hi I'm new to php and keep getting this error: "Warning: Invalid argument supplied for foreach() in /home/site/folder/upload.php on line 61."
I'm trying to build a form in which users can upload one or more photos automatically to a directory to then be displayed else where.
Whenever I use this form I created it functions properly on my website but unfortunately it keeps printing that error out and would like it to go away. Here is my code I'm working with:
<div>
<form action="upload.php" enctype="multipart/form-data" method="POST">
<input type="file" name="images[]" multiple="multiple"/>
<input type="submit" name="submit" value="upload images"/>
<form/>
<?php
// check if uploads directory exists
$dir = "images/";
if(!is_dir($dir))
{
echo "Directory not found, let's create the folder.";
mkdir($dir,"0777", true);
}
$countimg = 0;
$allimg = 0;
foreach($_FILES["images"]["name"] as $k=>$name)
{
$allimg++;
$imgname = $_FILES["images"]["name"][$k];
$sizeimg = $_FILES["images"]["size"][$k];
$tmpname = $_FILES["images"]["tmp_name"][$k];
//2.
$extension = strtolower(pathinfo($dir.$imgname, PATHINFO_EXTENSION));
if($extension=='png' || $extension=='jpg' ||$extension=='jpeg' ||$extension=='gif')
{
if($sizeimg < 2097152){
if(!file_exists($dir.$imgname)){
//1.
if(move_uploaded_file($tmpname,$dir.$imgname))
{
$countimg++;
}
}
}
}
}
echo "You are trying to upload $allimg images".'<br>';
echo "From $allimg image(s) - $countimg was/were uploaded with success".'<br>';
$z = $allimg - $countimg;
echo "$z image(s) were not uploaded: Not an image, over 2MB, or already uploaded.";
?>
</div>
Try
if (count($_FILES)) {
foreach($_FILES["images"]["name"] as $k=>$name) {
....
}
}
I tested your script, it works fine. The error message appears because you are not checking that a file got uploaded before starting the foreach. If I land on the page, the PHP code will still be triggered. To fix this, you may use the below:
<div>
<form action="upload.php" enctype="multipart/form-data" method="POST">
<input type="file" name="images[]" multiple="multiple"/>
<input type="submit" name="submit" value="upload images"/>
<form/>
<?php
if( $_POST['submit'] ) {
$dir = "images/";
if(!is_dir($dir))
{
echo "Directory not found, let's create the folder.";
mkdir($dir,"0777", true);
}
$countimg = 0;
$allimg = 0;
foreach($_FILES["images"]["name"] as $k=>$name)
{
$allimg++;
$imgname = $_FILES["images"]["name"][$k];
$sizeimg = $_FILES["images"]["size"][$k];
$tmpname = $_FILES["images"]["tmp_name"][$k];
//2.
$extension = strtolower(pathinfo($dir.$imgname, PATHINFO_EXTENSION));
if($extension=='png' || $extension=='jpg' ||$extension=='jpeg' ||$extension=='gif')
{
if($sizeimg < 2097152){
if(!file_exists($dir.$imgname)){
//1.
if(move_uploaded_file($tmpname,$dir.$imgname))
{
$countimg++;
}
}
}
}
}
echo "You are trying to upload $allimg images".'<br>';
echo "From $allimg image(s) - $countimg was/were uploaded with success".'<br>';
$z = $allimg - $countimg;
echo "$z image(s) were not uploaded: Not an image, over 2MB, or already uploaded.";
}
?>
</div>
if( $_POST['submit'] ) will ensure that the form is submitted prior to running the rest of the PHP code.

Simple File upload code in PHP

This issue might have been discussed multiple times but I wanted a simple PHP script to upload a file, without any separate action file and without any checks. Below is my written code:-
<html>
<head>
<title>PHP Test</title>
<form action="" method="post" enctype="multipart/form-data">
<input type="file" name="fileToUpload" id="fileToUpload">
<input type="submit" value="upload file" name="submit">
</form>
</head>
<body>
<?php echo '<p>FILE UPLOAD</p><br>';
$tgt_dir = "uploads/";
$tgt_file = $tgt_dir.basename($_FILES['fileToUpload']['name']);
echo "<br>TARGET FILE= ".$tgt_file;
//$filename = $_FILES['fileToUpload']['name'];
echo "<br>FILE NAME FROM VARIABLE:- ".$_FILES["fileToUpload"]["name"];
if(isset($_POST['submit']))
{
if(file_exists("uploads/".$_FILES["fileToUpload"]["name"]))
{ echo "<br>file exists, try with another name"; }
else {
echo "<br>STARTING UPLOAD PROCESS<br>";
if (move_uploaded_file($_FILES["fileToUpload"]["tmp_name"], $tgt_file))
{ echo "<br>File UPLOADED:- ".$tgt_file; }
else { echo "<br>ERROR WHILE UPLOADING FILE<br>"; }
}
}
?>
</body>
</html>
I saved it in /var/www/html/phps/ location. But everytime I try to upload the file, I get ERROR WHILE UPLOADING FILE error. What am I doing wrong here. P.S. I have no previous experience of PHP, I just started with bits & pieces from internet.
Thanks

<?php
$target_dir = "uploads/";
$target_file = $target_dir .
basename($_FILES["fileToUpload"]["name"]);
if(move_uploaded_file($_FILES["fileToUpload"]["tmp_name"], $target_file)) {
echo "The file ".basename( $_FILES["fileToUpload"]["name"]). " has been uploaded.";
} 
else {
echo "Sorry, there was an error uploading your file.";
}
?>
I hope that this thing will work and this is what you are in need of.
<?php
$name = $_POST['name'];
$image = $_FILES['fileToUpload']['name'];
$tempname = $_FILES['fileToUpload']['tmp_name'];
move_uploaded_file($tempname, "foldername/$image");?>

Uploading files with PHP

I am using a form for users to upload files to my website. I want to allow them to upload multiple photos at once, so I am using the HTML5 "multiple" attribute.
My HTML:
<form method="post" action="save.php">
<input type="file" name="uploads[]" multiple="multiple" />
<input type="submit" name="submit" value="submit"/>
</form>
save.php:
<?php
foreach ($_FILES['uploads']['name'] as $file) {
echo $file . "<br/>";
$file= time() . $_FILES['uploads']['name'];
$target= UPLOADPATH . $file;
move_uploaded_file($_FILES['uploads']['tmp_name'], $target)
or die('error with query 2');
}
But, for some reason when I run the script, I get an error saying undefined index: uploads. And an error saying that I have an invalid argument supplied for foreach(). What could I be dong wrong?
Thanks
UPDATE
Okay, setting the enctype="mulitpart/form-data" worked. Now, I am having trouble with moving the file. I am getting the error move_uploaded_file() expects parameter 1 to be string, array given. What am I doing wrong here?
Thanks again
You need the proper enctype to be able to upload files.
<form method="post" enctype="multipart/form-data" action="save.php">
try this html code: <form method="post" action="save.php" enctype="multipart/form-data">
Then in PHP:
if(isset($_FILES['uploads'])){
foreach ($_FILES['uploads']['name'] as $file) {
echo $file . "<br/>";
$file= time() . $_FILES['uploads']['name'];
$target= UPLOADPATH . $file;
move_uploaded_file($_FILES['uploads']['tmp_name'], $target)
or die('error with query 2');
}
} else {
echo 'some error message!';
}
In order to upload files in the first place, you need enctype="multipart/form-data" on your <form> tag.
But, when you upload multiple files, every key in $_FILES['uploads'] is an array (just like $_FILES['uploads']['name']).
You need to get the array key when looping, so you can process each file. See the docs for move_uploaded_file for more deatils.
<?php
foreach ($_FILES['uploads']['name'] as $key=>$file) {
echo $file."<br/>";
$file = time().$file;
$target = UPLOADPATH.$file;
move_uploaded_file($_FILES['uploads']['tmp_name'][$key], $target)
or die('error with query 2');
}
index.html
<form method="post" action="save.php" enctype="multipart/form-data">
<input type="file" name="uploads[]" multiple="multiple" />
<input type="submit" name="submit" value="Upload Image"/>
</form>
save.php
<?php
$file_dir = "uploads";
if (isset($_POST["submit"])) {
for ($x = 0; $x < count($_FILES['uploads']['name']); $x++) {
$file_name = time() . $_FILES['uploads']['name'][$x];
$file_tmp = $_FILES['uploads']['tmp_name'][$x];
/* location file save */
$file_target = $file_dir . DIRECTORY_SEPARATOR . $file_name;
if (move_uploaded_file($file_tmp, $file_target)) {
echo "{$file_name} has been uploaded. <br />";
} else {
echo "Sorry, there was an error uploading {$file_name}.";
}
}
}
?>
