upload files

**alessandroschiri** · 30-01-2016, 14.25.48

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> &nbsp; successfully registered !

                    </div>";

        }

        else

        {

            $msg = "<div class='alert alert-danger'>

                        <span class='glyphicon glyphicon-info-sign'></span> &nbsp; error while registering !

                    </div>";

        }

    }

    else {

        

        

        $msg = "<div class='alert alert-danger'>

                    <span class='glyphicon glyphicon-info-sign'></span> &nbsp; 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;

                    </div>";
                    
        $uploadOk = 0;
    }

    if($imageFileType != "jpg" && $imageFileType != "png" && $imageFileType != "jpeg"

    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;

        $query = "INSERT INTO users(user_name,user_email,user_pass, user_image) VALUES('$uname','$email','$new_password','$target_file')";
