Issue with Updating Database After Uploading a File

I am trying to upload the file and then insert the file name into the database.

Below is my code:

<?php
//connecting to database
session_start();
include('/applications/MAMP/htdocs/connect.php');
$u = $_SESSION['username'];


if (!empty($_FILES)) {
$file = $_FILES['Filedata'];

    $tempFile = $_FILES['Filedata']['tmp_name'];
    $targetPath = $_SERVER['DOCUMENT_ROOT'] . $_REQUEST['folder'] . '/';
    $targetFile =  str_replace('//','/',$targetPath) . $_FILES['Filedata']['name'];

    // $fileTypes  = str_replace('*.','',$_REQUEST['fileext']);
    // $fileTypes  = str_replace(';','|',$fileTypes);
    // $typesArray = split('\|',$fileTypes);
    // $fileParts  =开发者_如何学Python pathinfo($_FILES['Filedata']['name']);

    // if (in_array($fileParts['extension'],$typesArray)) {
        // Uncomment the following line if you want to make the directory if it doesn't exist
        // mkdir(str_replace('//','/',$targetPath), 0755, true);
        $n = $file['name'];
        move_uploaded_file($tempFile,$targetFile);
        echo str_replace($_SERVER['DOCUMENT_ROOT'],'',$targetFile);
        mysqli_select_db($connect,"people");
$i = "update users set filelocation = '$n' where sessionusername = '$u'";
$q = mysqli_query($connect,$i);
    // } else {
    //  echo 'Invalid file type.';
    // }
}


?>

The file is being uploaded successfully, but the name is not getting updated in the database.

Please help me.

$n = $file['name']; will return nothing since $file is not declared anywhere. You probably want to use:

$n = $_FILES['Filedata']['name'];

or anything else declared you really want to put in your DB ;-)

you have $n = $file['name'];

it should be $n = $targetFile

But first of all - clean your code ;)

I cleaned up it for you. Check if this work.

<?php
session_start();
include('/applications/MAMP/htdocs/connect.php');
mysqli_select_db("people");

if (!isset($_REQUEST['folder'])) $_REQUEST['folder'] = "";

if (!empty($_FILES)) {
    $tempFile = $_FILES['Filedata']['tmp_name'];
    $targetPath = $_SERVER['DOCUMENT_ROOT'] . $_REQUEST['folder'] . '/';
    $targetFile =  str_replace('//','/',$targetPath) . $_FILES['Filedata']['name'];

    move_uploaded_file($tempFile,$targetFile);
    $i = "UPDATE users SET filelocation = '$targetFile' WHERE sessionusername = '{$_SESSION['username']}'";
    $q = mysqli_query($i);

    //debug
    echo "$targetFile<br/>
        $tempFile<br/>
        $i<br/>";
    echo mysqli_error();
}
else {
    echo "No file";
}
?>
