upload files
Ciao a tutti. Sto elaborando un form per la registrazione ad un sito. Oltre a nome, mail e password vorrei permettere l'upload di una foto come profilo. Ho scritto questo codice anche grazie a diversi tutorial sul web ma mostra un errore "Notice: Undefined index: image". Sapreste aiutarmi? Grazie mille :)
Codice PHP:
<?php
session_start();
if(isset($_SESSION['userSession'])!="")
{
header("Location: home.php");
}
include_once 'dbconnect.php';
if(isset($_POST['btn-signup']))
{
$uname = $MySQLi_CON->real_escape_string(trim($_POST['user_name']));
$email = $MySQLi_CON->real_escape_string(trim($_POST['user_email']));
$upass = $MySQLi_CON->real_escape_string(trim($_POST['password']));
$new_password = md5($upass);
$file = rand(1000,100000)."-".$_FILES['image']['name'];
$file_loc = $_FILES['image']['tmp_name'];
$folder="myupload";
move_uploaded_file($file_loc, $folder.$file);
$check_email = $MySQLi_CON->query("SELECT user_email FROM users WHERE user_email='$email'");
$count=$check_email->num_rows;
if($count==0){
$query = "INSERT INTO users(user_name,user_email,user_pass, user_image) VALUES('$uname','$email','$new_password','$folder/$file')";
if($MySQLi_CON->query($query))
{
$msg = "<div class='alert alert-success'>
<span class='glyphicon glyphicon-info-sign'></span> successfully registered !
</div>";
}
else
{
$msg = "<div class='alert alert-danger'>
<span class='glyphicon glyphicon-info-sign'></span> error while registering !
</div>";
}
}
else {
$msg = "<div class='alert alert-danger'>
<span class='glyphicon glyphicon-info-sign'></span> sorry email already taken !
</div>";
}
$MySQLi_CON->close();
}
?>

Correggi il tag form aggiungendo l'enctype:
Codice HTML:
<form class="form-signin" method="post" enctype="multipart/form-data" id="register-form">

Perfetto, grazie dell'aiuto. Questo è il codice con l'implementazione dell'uploading, anche se non ho controllato se funziona anche il multiple upload..
Codice PHP:
<?php
//inizializzo sessione.
session_start();
if(isset($_SESSION['userSession'])!="")
{
header("Location: home.php");
}
include_once 'dbconnect.php';
if(isset($_POST['btn-signup']))
{
$uname = $MySQLi_CON->real_escape_string(trim($_POST['user_name']));
$email = $MySQLi_CON->real_escape_string(trim($_POST['user_email']));
$upass = $MySQLi_CON->real_escape_string(trim($_POST['password']));
//password criptata
$new_password = md5($upass);
//parametri della foto da caricare
$target_dir = "myupload/";
$target_file = $target_dir . basename($_FILES["image"]["name"]);
$uploadOk = 1;
$imageFileType = pathinfo($target_file,PATHINFO_EXTENSION);
// Check if image file is a actual image or fake image
$check = getimagesize($_FILES["image"]["tmp_name"]);
if($check !== false) {
echo "File is an image - " . $check["mime"] . ".";
$uploadOk = 1;
} else {
$msg = "<div class='alert alert-danger'>
<span class='glyphicon glyphicon-info-sign'></span> Sorry, this file is not an image.
</div>";
$uploadOk = 0;
}
// Allow certain file formats
if($imageFileType != "jpg" && $imageFileType != "png" && $imageFileType != "jpeg"
&& $imageFileType != "gif" ) {
$msg = "<div class='alert alert-danger'>
<span class='glyphicon glyphicon-info-sign'></span> Sorry, only JPG, JPEG, PNG & GIF files are allowed.
</div>";
$uploadOk = 0;
}
// Check if $uploadOk is set to 0 by an error
if ($uploadOk == 0) {
echo "Sorry, your file was not uploaded.";
// if everything is ok, try to upload file
} else {
if (move_uploaded_file($_FILES["image"]["tmp_name"], $target_file)) {
echo "The file ". basename( $_FILES["image"]["name"]). " has been uploaded.";
} else {
echo "Sorry, there was an error uploading your file.";
}
}
$check_email = $MySQLi_CON->query("SELECT user_email FROM users WHERE user_email='$email'");
$count=$check_email->num_rows;
if($count==0){
$query = "INSERT INTO users(user_name,user_email,user_pass, user_image) VALUES('$uname','$email','$new_password','$target_file')";
if($MySQLi_CON->query($query))
