I can't upload pdf files in php - php

Question

Now i am trying to upload pdf files by the form in php but when i upload it, it doesn't work because function is_uploaded_file($_FILES['file']['tmp_name']) return false
How can i solve it please ??
I am using localhost and I verify php.ini
; Whether to allow HTTP file uploads.
; http://php.net/file-uploads
file_uploads = On
; Temporary directory for HTTP uploaded files (will use system default if not
; specified).
; http://php.net/upload-tmp-dir
upload_tmp_dir = "E:/wamp/tmp"
; Maximum allowed size for uploaded files.
; http://php.net/upload-max-filesize
upload_max_filesize = 50M
This is my code :
Class
<?php
require '../includes/master.inc.php';
// Kick-out users who aren't logged in as an admin
$auth->requireAdmin('../login_admin_cp.php');
if (isset($_POST['btnsubmit'])) {
$error->blank($_POST['field_name'], "field_name");
if ($error->ok()) {
$field_name = $_POST['field_name'];
if (is_uploaded_file($_FILES['file']['tmp_name'])) {
// exit;
$mypath = "upload/";
$file_name = $_FILES['file']['name'];
$tmp = $_FILES['file']['tmp_name'];
$n = $mypath . $file_name;
$t = $_FILES['file']['size'];
$filesize = round($t / 1024) . " KB";
$extintion = strchr($n, ".");
$extintion = strtolower($extintion);
$file_extintion_allow = array(".pdf");
if ($n == "") {
echo "Error in upload";
} elseif (!in_array($extintion, $file_extintion_allow)) {
echo "من فضلك ادخل المادة بطريقة صحيحة";
exit;
} else {
//rename the file when upload by query name
$quaryname = rand(11111, 99999);
$rename = "../" . $mypath . $quaryname . $extintion;
$URL = substr($rename, 10, strlen($rename));
move_uploaded_file($tmp, $rename);
if (!empty($_POST['hide'])) {
$hide = $_POST['hide'];
$db->query("insert into field (field_name,url,hide)values('$field_name','$URL','$hide')");
$sess->set_flashdata('success_msg', 'تم حفظ المادة بنجاح');
redirect("field_new.php");
} else {
$db->query("insert into field (field_name,url,hide)values('$field_name','$URL','0')");
$sess->set_flashdata('success_msg', 'تم حفظ المادة بنجاح');
redirect("field_new.php");
}
}
} else {
exit;
}
} else {
$sess->set_flashdata('error_msg', 'حقل المادة فارغ');
}
}
// View
include('views/header.php');
include('views/field_form_new.php');
include('views/footer.php');
?>

Maybe the file is to big or the destination directory is not writeable for php/apache.
Check the folder permission "E:/wamp/tmp" and try to upload a smaller file.
If a smaller file works, check these values in the php.ini file:
post_max_size
max_input_time
memory_limit
