I need some advice and guide line.
I am trying to upload image into a folder using link. And I am unable to upload an image.
I am trying this code. This shows error message :
[function.move-uploaded-file]: failed to open stream: HTTP wrapper does not support writeable connections
<?php
if ($_FILES["file"]["error"] > 0)
{
echo "Return Code: " . $_FILES["file"]["error"] . "<br />";
}
else
{
if (file_exists("http://localhost.myimage.com/uploads/" . $_FILES["file"]["name"]))
{
echo $_FILES["file"]["name"] . " already exists. ";
}
else
{
move_uploaded_file($_FILES["file"]["tmp_name"],
"http://localhost.myimage.com/uploads/" . $_FILES["file"]["name"]);
echo "Stored in: " . "upload/" . $_FILES["file"]["name"];
}
}
?>
<html>
<body>
<form action="" method="post"
enctype="multipart/form-data">
<label for="file">Filename:</label>
<input type="file" name="file" id="file" />
<br />
<input type="submit" name="submit" value="Submit" />
</form>
</body>
</html>
Is it possible ?
The destination of the moved file needs to be an absolute path to the server, i.e.
move_uploaded_file( $_FILES["file"]["tmp_name"], $_SERVER['DOCUMENT_ROOT'] ."/uploads/" . $_FILES["file"]["name"]);
You are supplying file_exists and move_uploaded_file with an URL. Try supplying a file on the hard drive instead. Change:
file_exists("http://localhost.myimage.com/uploads/" . $_FILES["file"]["name"])
to
file_exists($_SERVER['DOCUMENT_ROOT'] . "uploads/" . $_FILES["file"]["name"])
and similar to move_uploaded_file since that's where the error originated.
No it's not possible this way.
You try to store the uploaded file on a wrong destination.
I assume you own "http://localhost.myimage.com/uploads/" and wan't to store the file under '/uploads/' in your server.
If your project is installed e.g. under /var/www/my_prj/
And your upload is under /var/www/my_prj/uploads
then your code should look like:
move_uploaded_file($_FILES["file"]["tmp_name"],
"/uploads/" . $_FILES["file"]["name"]);
This only applies when '/var/www/my_prj/' is the DocumentRoot for your apache configured host.

I am new to PHP and am trying to create a page to upload a jpeg file. The webpage seems to run fine and it appears the file is uploading, however the file is not appearing on the server. Any help you can provide will be great.
The PHP code is:
<?php
$target_dir="/var/www/html/";
$fileName=$_FILES['file']['name'];
$target_file=$target_dir . basename($fileName);
$imageFileType=pathinfo($target_file,PATHINFO_EXTENSION);
$fileTempName=$_FILES["file"]["tmp_name"];
$fileType=$_FILES["file"]["type"];
$fileSize=$_FILES["file"]["size"];
$fileError=$_FILES["file"]["error"];
if(($fileType=="image/jpeg")&&($fileSize<100000)){
if($fileError>0){
echo "Return Code: " . $fileError . "<br />";
}
else{
echo "Upload: " .$fileName . "<br />";
echo "Type: " . $fileType . "<br />";
echo "Size: " . ($fileSize / 1024) . " kb<br />";
echo "Temp file: " . $fileTempName . "<br />";
if (file_exists($fileName)){
unlink($fileName);
}
move_uploaded_file($fileTempName,$target_file);
echo "<br><br>File Temp Name: " .$fileTempName."\r\n <br>";
echo "Uploaded file stored as : " .$target_file ."<br><br>";
}
}
else{
echo "File is not a JPEG or too big.";
}
?>
And the HTML code is as follows:
<html>
<body>
<form action="save2web.php" method="post" enctype="multipart/form-data">
<label for="file">Filename:</label>
<input type="file" name="file" id="file"/>
<br/>
<input type="submit" name="submit" value="Upload"/>
</form>
</body>
</html>
The problem is that, you don't check the returned value of move_uploaded_file() at all. But looks like, you're running your script on the host, and since most host disallow relative paths, you'd better provide an absolute.
So try, replacing:
$target_dir = "/var/www/html/"; // <- This is relative, which might be blocked due to security reasons
with
$target_dir = dirname(__FILE__) . "/var/www/html/"; // dirname(__FILE__) is a path to root
And then, make sure that the file was uploaded:
if (!move_uploaded_file(...)) {
// error
}
Presuming your server is linux from the path, you may need to change the permissions of the folder your trying to upload to, try changing the folder owner to www-data, this fixed the same issue for me.
Change your target directory like this. Add a .(dot) before the directory name.
$target_directory = './var/www/html';
I'm trying to upload and save file in dir called images through a form. Form looks like this:
<form name="spremi" action="spremaj.php" method="post" enctype="multipart/form-data">
<input type="file" id="file" name="image" />
<input type="submit" value="Send" name="send" />
</form>
And php script looks like this:
if (file_exists("images/" . $_FILES["file"]["name"]))
{
echo $_FILES["file"]["name"] . " already exists. ";
}
else
{
move_uploaded_file($_FILES["file"]["tmp_name"],"images/" . $_FILES["file"]["name"]);
echo "Stored in: " . "images/" . $_FILES["file"]["name"];
}
Script always prints message "already exists". I know that questions like this were already asked, but none of the answers helped me. This code didn't work either on localhost, or web server. Thank you.
In your html form you do not have a file parameter so your php needs to accept image so change
if (file_exists("images/" . $_FILES["image"]["name"]))
{
echo $_FILES["image"]["name"] . " already exists. ";
}else
move_uploaded_file($_FILES["file"]["tmp_name"],"images/" . $_FILES["file"]["name"]);
to
if (file_exists("images/" . $_FILES["image"]["name"]))
{
echo $_FILES["image"]["name"] . " already exists. ";
}else
move_uploaded_file($_FILES["image"]["tmp_name"],"images/" . $_FILES["image"]["name"]);
I'm trying to debug an issue with a WordPress 3.5.1 where I cannot upload media via HTTP at all; the media uploader simply says "HTTP error" and fails. To diagnose what's going on, I decided to write (i.e. copy from w3schools) a really basic PHP file uploader to see if there's something weird going on behind the scenes. But for some reason, the $_FILE structure doesn't contain any information at all, even in the most basic of examples:
file.php :
<html>
<body>
<form action="upload.php" method="post" enctype="multipart/form-data">
<label for="file">Filename:</label>
<input type="file" name="file" id="file"><br>
<input type="submit" name="submit" value="Submit">
</form>
</body>
</html>
upload.php :
<?php
if ($_FILES["file"]["error"] > 0)
{
echo "Error: " . $_FILES["file"]["error"] . "<br>";
}
else
{
echo "Upload: " . $_FILES["file"]["name"] . "<br>";
echo "Type: " . $_FILES["file"]["type"] . "<br>";
echo "Size: " . ($_FILES["file"]["size"] / 1024) . " kB<br>";
echo "Stored in: " . $_FILES["file"]["tmp_name"];
}
?>
In every browser I've tried, with every file I've tried, this just outputs:
Upload:
Type:
Size: 0 kB
Stored in:
and printing $_FILES shows that it is just an empty array.
I'm using PHP-5 on shared hosting (lunarpages), but the php.ini file has file_uploads on and the size of the files I tried is nowhere even close to the upload_max_filesize. I am ready to throw my laptop against a wall, so any help would save me a couple thousand dollars.
<html>
<body>
<form action="upload.php" method="post" enctype="multipart/form-data">
<label for="file">Filename:</label>
<input type="file" name="file" id="file"><br>
<input type="submit" name="submit" value="Submit">
</form>
<?php
phpinfo();
?>
</body>
</html>
This worked for me, $_FILES was not empty, using a common Debian installation, PHP 5.2; try to adjust the permissions of your files and direcotires to 777
I had a similar issue once with a shared host. Turned out that I had no tmp directory set, therefore nothing was being uploaded. Check with your host that your php.ini is set up correctly and that a tmp directory exists for uploads and that you have write permissions for it.
$target="Your Path";
if(move_uploaded_file($_FILES['file']['tmp_name'], $target))
{
echo "Upload: " . $_FILES["file"]["name"] . "<br>";
echo "Type: " . $_FILES["file"]["type"] . "<br>";
echo "Size: " . ($_FILES["file"]["size"] / 1024) . " kB<br>";
echo "Stored in: " . $_FILES["file"]["tmp_name"];
}
else
{
echo "Unable to move temp file to target.";
}
If it is not yet too late, you should check your apache logs. The most probable cause is that the apache - and so your php interpreter - has no permission to your predefined upload directory.
I have an image id='canvasImg' and I can not figure out how to take this image and save it to the server.
I tried saving the contents to a form and then putting the contents in a png file after decode but it didn't work.
You will need to use a simple file form upload
HTML
<form action="upload_file.php" method="post" enctype="multipart/form-data">
<input type="file" name="file" id="file" />
<input type="submit" name="submit" value="Submit" />
</form>
PHP (upload_file.php)
if (file_exists("upload/" . $_FILES["file"]["name"])) {
echo $_FILES["file"]["name"] . " already exists. ";
} else {
move_uploaded_file($_FILES["file"]["tmp_name"],
"upload/" . $_FILES["file"]["name"]);
echo "Stored in: " . "upload/" . $_FILES["file"]["name"];
}
Does anyone know any good tutorial on how to upload a file with php and save the files path to a sql server?
To upload a file you need at least a HTML POST form with multipart/form-data encoding. Therein you put an input type="file" field to browse the file and a submit button to submit the form.
<form action="upload.php" method="post" enctype="multipart/form-data">
<input type="file" name="file">
<input type="submit">
</form>
In the upload.php the uploaded file is accesible by $_FILES with the field name as key.
$file = $_FILES['file'];
You can get its name as follows:
$name = $file['name'];
You need to move it to a permanent location using move_uploaded_file(), else it will get lost:
$path = "/uploads/" . basename($name);
if (move_uploaded_file($file['tmp_name'], $path)) {
// Move succeed.
} else {
// Move failed. Possible duplicate?
}
You can store the path in database the usual way:
$sql = "INSERT INTO file (path) VALUES ('" . mysqli_real_escape_string($path) . "')";
// ...

HTML
<html>
<body>
<form action="upload_file.php" method="post"
enctype="multipart/form-data">
<label for="file">Filename:</label>
<input type="file" name="file" id="file" />
<br />
<input type="submit" name="submit" value="Submit" />
</form>
</body>
</html>
PHP
<?php
if ($_FILES["file"]["error"] > 0)
{
echo "Return Code: " . $_FILES["file"]["error"] . "<br />";
}
else
{
if (file_exists("upload/" . $_FILES["file"]["name"]))
{
echo $_FILES["file"]["name"] . " already exists. ";
}
else
{
move_uploaded_file($_FILES["file"]["tmp_name"],
"upload/" . $_FILES["file"]["name"]);
echo "Stored in: " . "upload/" . $_FILES["file"]["name"]; //<- This is it
}
}
?>
Note that to upload the file you need to specify the path to save the file. If you save the file you already know it path.
