Issue
I'm trying to upload a file in a server with PHP, but i have some problems. I have found this guide: http://www.sumedh.info/articles/store-upload-image-postgres-php-2.html. My html is:
<form action="img_user.php" method="POST" enctype="multipart/form-data" >
<button id="buttonImgProf" class="btn" type="button" onclick="caricaImgProf()">Inserisci un immagine</button>
<div id="imgProfLoader" class="postContent" style="display:none;">
Name : <input type="text" name="name" size="25" length="25" value="">
<input type="file" name="userfile"></input>
<button class="btn" type="submit">Carica immagine</button>
</div>
</form>
(parts are not displays because i use javascript). The php code is:
$uploaddir = 'localhost'; //i have try lots of dir, maybe the error is here?
$uploadfile = $uploaddir . basename($_FILES['userfile']['name']);
$name = $_POST['name'];
echo $_FILES['userfile']['tmp_name'];
if (move_uploaded_file($_FILES['userfile']['tmp_name'], $uploadfile))
{ echo "File is valid, and was successfully uploaded.\n";
}
else { echo "File not uploaded"; }
the output is File not uploaded
Solution
your upload path($uploaddir = 'localhost'; ) should be physical path not should be url so change localhost to any path like ($uploaddir = "uploads/")
full demo code :
First, ensure that PHP is configured to allow file uploads.
In your "php.ini" file, search for the file_uploads directive, and set it to On: file_uploads = On
then your form page
<!DOCTYPE html>
<html>
<body>
<form action="upload.php" method="post" enctype="multipart/form-data">
Select image to upload:
<input type="file" name="fileToUpload" id="fileToUpload">
<input type="submit" value="Upload Image" name="submit">
</form>
</body>
</html>
Make sure that the form uses method="post"
The form also needs the following attribute: enctype="multipart/form-data". It specifies which content-type to use when submitting the form
The "upload.php" file contains the code for uploading a file:(it is action page for file upload form)
<?php
$target_dir = "uploads/";
if (is_dir($upload_dir) && is_writable($upload_dir)) {
// you can write anything in this folder
} else {
die('Upload directory is not writable, or does not exist.');
}
$target_file = $target_dir . basename($_FILES["fileToUpload"]["name"]);
$uploadOk = 1;
$imageFileType = pathinfo($target_file,PATHINFO_EXTENSION);
// Check if image file is a actual image or fake image
if(isset($_POST["submit"])) {
$check = getimagesize($_FILES["fileToUpload"]["tmp_name"]);
if($check !== false) {
echo "File is an image - " . $check["mime"] . ".";
$uploadOk = 1;
} else {
echo "File is not an image.";
$uploadOk = 0;
}
// Check if $uploadOk is set to 0 by an error
if ($uploadOk == 0) {
echo "Sorry, your file was not uploaded.";
// if everything is ok, try to upload file
} else {
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.";
}
}
}
?>
PHP script explained:
$target_dir = "uploads/" - specifies the directory where the file is going to be placed
$target_file specifies the path of the file to be uploaded
$uploadOk=1 is not used yet (will be used later)
$imageFileType holds the file extension of the file
Next, check if the image file is an actual image or a fake image
Note: You will need to create a new directory called "uploads" in the directory where "upload.php" file resides. The uploaded files will be saved there.
