How to upload a file in PHP

Question

I am having an issue while uploading a file, my code is here:

if (isset($_POST['name']) && isset($_POST['email']) && isset($_POST['DOB']) && isset($_POST['address']) && isset($_POST['phone']) && isset($_FILES['file'])) {
    # code...
$n=mysql_real_escape_string(htmlspecialchars($_POST['name']));
$e=mysql_real_escape_string(htmlspecialchars($_POST['email']));
$dob=mysql_real_escape_string(htmlspecialchars($_POST['DOB']));
$a=mysql_real_escape_string(htmlspecialchars($_POST['address']));
$p=mysql_real_escape_string(htmlspecialchars($_POST['phone']));
$t=time();
$d_of_reg=date('D M Y @ H.i.s', $t);

$cv=$_FILES['file']['name'];



// connect to the db here

mysql_connect('localhost','root','') or die('Please we could not connect.. Try-again!!!');
mysql_select_db('joblessmen')or die('Please we could not connect to our database... Try-again!!!');

$sql="INSERT INTO `users`(`name`, `email`, `DOB`, `address`, `phone number`, `id`, `date_of_reg`) VALUES ('$n','$e','$dob','$a','$p','','$d_of_reg')";

if($sql_run=mysql_query($sql))
{
    echo "Thank you for registering. Joblessmen";
}



}

So I want to get the files to the server and it's telling me nothing when I echo $_FILE['file']['name'] Please what I have to do? My wamp settings in php_fileinfo are on, any help would be appreciated.

please this is the other part for uploading the file which is not working i want it to upload a jpg and doc,docx,pdf file only this is my php code

if ( isset($_FILES['file']['name']) && isset($_POST['name']) && isset($_POST['email']) && isset($_POST['DOB']) && isset($_POST['address']) && isset($_POST['phone'])) {
        # code...
    $n=mysql_real_escape_string(htmlspecialchars($_POST['name']));
    $e=mysql_real_escape_string(htmlspecialchars($_POST['email']));
    $dob=mysql_real_escape_string(htmlspecialchars($_POST['DOB']));
    $a=mysql_real_escape_string(htmlspecialchars($_POST['address']));
    $p=mysql_real_escape_string(htmlspecialchars($_POST['phone']));
    $t=time();
    $d_of_reg=date('D M Y @ H.i.s', $t);


    //$cv=$_FILES['file']['name'];

/*

        echo "Thank you for registering. Joblessmen";
        //echo $cv=$_FILES['file']['name'];
    }



    }

so i want it to upload a file from either of the extensions but it not working it is tell undefined index please what can i do

Answer 1

1) Make sure you have mentioned enctype="multipart/form-data" parameter

2) You can access the file by

$file=$_FILES['file']['name'];

$_FILES['name']['tmp_name'] will give you the temporary path of the file.

Then you can use the below function to move the file from temporary path to your file system.

move_uploaded_file($_FILES['name']['tmp_name'],"Your filesystem path");

Answer 2

move_uploaded_file($_FILES['file']['tmp_name'] ,"upload/".$_FILES['file']['name']); $file= $_FILES['file']['name'];

Answer 3

Here is a code with multiple tests to do what you want :

// Define some variables
$max_size = 200000;
$files_directory = $_SERVER['DOCUMENT_ROOT'].'/my_files_directory/';
$file_name = basename($_FILES['my_image']['name']);
$file_size = filesize($_FILES['my_image']['tmp_name']);
$file_extension = strrchr($_FILES['my_image']['name'], '.'); 

// Available extensions
$extensions = array('.png', '.gif', '.jpg');

// Return false if extension is not allowed
if(!in_array($file_extension, $extensions))
    return false;

// Return false if file size is over limit
if($file_size > $max_size)
    return false;

// Fast way to rewrite file name, do your own
$final_file_name = strtr($file_name, 'ÀÁÂÃÄÅÇÈÉÊËÌÍÎÏÒÓÔÕÖÙÚÛÜÝàáâãäåçèéêëìíîïðòóôõöùúûüýÿ', 'AAAAAACEEEEIIIIOOOOOUUUUYaaaaaaceeeeiiiioooooouuuuyy');
$final_file_name = preg_replace('/([^.a-z0-9]+)/i', '-', $final_file_name);

// Move the file to your server
move_uploaded_file($_FILES['my_image']['tmp_name'], $files_directory.$final_file_name);

// Here is the link to your file, adapt it
$file = 'http://'.$_SERVER['HTTP_HOST'].'/my_files_directory/'.$final_file_name;

Moreover, you need to have this line when opening your form :

<form method="your_method" action="your_action" enctype="multipart/form-data">
