Get uploaded file name? - php

Question

I am trying PHP Script in which users can upload files.
I am Using Script from php.net.
It ran successfully on my localhost. But the problem is how can i Get Uploaded file name for save image path it into my database?
Code -
<?php
header('Content-Type: text/plain; charset=utf-8');
try {
// Undefined | Multiple Files | $_FILES Corruption Attack
// If this request falls under any of them, treat it invalid.
if (
!isset($_FILES['upfile']['error']) ||
is_array($_FILES['upfile']['error'])
) {
throw new RuntimeException('Invalid parameters.');
}
// Check $_FILES['upfile']['error'] value.
switch ($_FILES['upfile']['error']) {
case UPLOAD_ERR_OK:
break;
case UPLOAD_ERR_NO_FILE:
throw new RuntimeException('No file sent.');
case UPLOAD_ERR_INI_SIZE:
case UPLOAD_ERR_FORM_SIZE:
throw new RuntimeException('Exceeded filesize limit.');
default:
throw new RuntimeException('Unknown errors.');
}
// You should also check filesize here.
if ($_FILES['upfile']['size'] > 1000000) {
throw new RuntimeException('Exceeded filesize limit.');
}
// DO NOT TRUST $_FILES['upfile']['mime'] VALUE !!
// Check MIME Type by yourself.
$finfo = new finfo(FILEINFO_MIME_TYPE);
if (false === $ext = array_search(
$finfo->file($_FILES['upfile']['tmp_name']),
array(
'jpg' => 'image/jpeg',
'png' => 'image/png',
'gif' => 'image/gif',
),
true
)) {
throw new RuntimeException('Invalid file format.');
}
// You should name it uniquely.
// DO NOT USE $_FILES['upfile']['name'] WITHOUT ANY VALIDATION !!
// On this example, obtain safe unique name from its binary data.
if (!move_uploaded_file(
$_FILES['upfile']['tmp_name'],
sprintf('./uploads/%s.%s',
sha1_file($_FILES['upfile']['tmp_name']),
$ext
)
)) {
throw new RuntimeException('Failed to move uploaded file.');
}
echo 'File is uploaded successfully.';
} catch (RuntimeException $e) {
echo $e->getMessage();
}
?>
I am confused how can i pass uploaded image name into variable and then store it into my database?
I have tried
$path = $_FILES['upfile']['tmp_name'];
echo $path;
but no luck. anyone here can help me out?

To get the information of uploaded file use $_FILES['upfile']['tmp_name'] for temp name and for real name $_FILES['upfile']['name']
$tmp_file = $_FILES['upfile']['tmp_name']; // store temporary file name
$real_file_name = $_FILES['upfile']['name']; // store the name of the file like upload.png
For example the uploaded file is ccd37b2ce541f407cabfc58be4e4af952fce7bde.jpg
$tmp_file = $_FILES['upfile']['tmp_name']; // this is a random generated temp image name like /var/www/html/php‌​yCWSRd.jpg
$real_file_name = $_FILES['upfile']['name']; // which is ccd37b2ce541f407cabfc58be4e4af952fce7bde.jpg
To move this file to uploads directory
$path = 'uploads/' . $real_file_name; // this will be uploads/ccd37b2ce541f407cabfc58be4e4af952fce7bde.jpg
if (!move_uploaded_file($_FILES['upfile']['tmp_name'], $path)) {
throw new RuntimeException('Failed to move uploaded file.');
}
