Save full URL link in database when image upload - php

Question

My upload form for images is working good. Save name and path to database. I want to save full url to image along whit name instead just a name. What I mean is now in DB is saved file_name.jpg I want to save http://example.com/images/file_name.jpg. Here is the upload.php
define('MAX_FILE_SIZE', 20000000430);
$uploadDir = "../../img/";
$permitted = array('image/jpeg', 'image/jpeg', 'image/png', 'image/gif');
$fileName = $_FILES['image']['name'];
$tmpName = $_FILES['image']['tmp_name'];
$fileSize = $_FILES['image']['size'];
$fileType = $_FILES['image']['type'];
// make a new image name
$ext = substr(strrchr($fileName, "."), 1);
// generate the random file name
$randName = md5(rand() * time());
// image name with extension
$myFile = $randName . '.' . $ext;
// save image path
$path = $uploadDir . $myFile;
if (in_array($fileType, $permitted))
{
$result = move_uploaded_file($tmpName, $path);
if (!$result)
{
echo "Error uploading image file";
exit;
}
else
{
// keep track post values
$name = $_POST['name'];
$description = $_POST['description'];
// update data
$pdo = Database::connect();
$pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
$sql = "UPDATE food set name = ?, image = ?, path = ?, description = ?
WHERE id = ?";
$q = $pdo->prepare($sql);
$q->execute(array($name,$myFile,$path,$description,$id));
Database::disconnect();
echo "<code>Information updated!!</code>";
}
}
What I try is to put the URL in $uploadDir.
$uploadDir = "http://example.com/img/";
But I get this error.
Warning: move_uploaded_file(http://example.com/img/75a13564a8f3305fb0a30ab95487b8de.jpg): failed to open stream: HTTP wrapper does not support writeable connections
Also tried something like this and got same error
define('domainURL', 'http://'.$_SERVER['HTTP_HOST']);
$path = domainURL . $uploadDir . $myFile;

Answer 1

The move_uploaded_file function does not accept file url.
It accepts image actual path.
Because, your file is getting moved physically.
e.g. $path = $_SERVER['DOCUMENT_ROOT'] . 'img/'

Answer 2

You may use relative or absolute path.
Relative path is "../../img/";
Absolute path should be like "/www/htdocs/img/"; (you can see absolute path in FTP client)
And you cannot use URL.
For store in DB use another one variable with URL

Answer 3

assign the upload path in a php variable and use $path to store it in database..
$path = "www.sitename.com/uploads/".$filename ;
