I can't upload pdf files in 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');
?>

Form

• Ramesh: What is the size of the file you are uploading?

Answer 1

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

• Rukmal Dias: thanks for the answer. i had only changed the upload_max_filesize = 50M entry in php.ini file. after setting post_max_size = 50M it works..
