Błąd przy wrzucaniu zdjęcia

0

Witam
Mam problem z wrzuceniem pliku na mojej stronie. Podczas wykonywania skryptu wyskakuje mi błąd "Undefined index: image" w linijce z $_FILES. Przeglądałem już masę stron i nie mam pojęcia co jest nie tak :( mam nadzieje że pomożecie.

 if(isset($_POST['submit_post'])){
        $title = strip_tags($_POST['title']);
        $date = date('Y-m-d h:i:s');
            if($_FILES['image']['name']){
            $image_name = $_FILES['image']['name'];
            $image_tmp = $_FILES['image']['tmp_name'];
            $image_size = $_FILES['image']['size'];
            $image_ext = pathinfo($image_name,PATHINFO_EXTENSION);
            $image_path = '../images/'.$image_name;
            $image_db_path = 'images/'.$image_name;

            if($image_size < 1000000){
                if($image_ext == 'jpg' || $image_ext == 'png' || $image_ext == 'gif'){
                    if(move_uploaded_file($image_tmp, $image_path)){
                        $ins_sql = "INSERT INTO posts (title, description, image, category, status, date, author) VALUES ('$title', '$_POST[description]', '$image_db_path', '$_POST[category]', '$date', '$_SESSION[user]')";
                        if(mysqli_query($conn, $ins_sql)){
                            header('post_list.php');
                        } else{
                            $error = '<div class="alert alert-danger">The Query Was Not Working!</div>';
                        }
                    } else {
                        $error = '<div class="alert alert-danger">Sorry, Unfortunately Image host not been uploaded!</div>';
                    }

                } else{
                    $error = '<div class="alert alert-danger">Image Format was not Correct!</div>';
                }
            } else{
                $error = '<div class="alert alert-danger">Image File Size is much bigger then Expect!</div>';
            }
        } else {
            $ins_sql = "INSERT INTO posts (title, description, category, status, date, author) VALUES ('$title', '$_POST[description]', '$_POST[category]', '$_POST[status]', '$date', '$_SESSION[user]')";
            if(mysqli_query($conn, $ins_sql)){
                header('post_list.php');
                } else{
                    $error = '<div class="alert alert-danger">The Query Was Not Working!</div>';
                }
        }
    }

a to mój formularz :

 <div class="form-group">
                      <label for="image">Upload an Image</label>
                      <input id="image" type="file" name="image" class="btn btn-primary">
                  </div>

Zamiast $_FILES['image'] użyj po prostu $_GET['image'] (lub $_POST['image'] zależnie od metody).

Mógłbym Ci powiedzieć co zrobić, ale też mógłbym zamiast ryby dać Ci wędkę. Więc proponuję zrobić prostego debuga i wpisać sobie w Twoim programie na początku

var_dump($_GET); / var_dump($_POST);
oraz
var_dump($_FILES);.

Dzięki temu zobaczysz co siedzi w tych zmiennych i będziesz łatwiej mógł ustalić przyczynę błędu.

Mógłby mi ktoś z tym pomóc ? :( siedzę już nad tym parę godzin i nie mam pojęcia czemu to nie chodzi :( przy var_dump($_FILES); wychodzi mi błąd że tablica jest pusta :(

I na pewno masz włączone w php.ini:

file_uploads = On

oraz w formularzu masz parametr enctype="multipart/form-data"?

PS: możesz wykonać metodę phpinfo() i zobaczyć czy jest włączone file_uploads.

Gdzieś wyczytałem że należałoby dodać taką linijkę o maksymalnym rozmiarze

Więc zamiast

<input id="image" type="file" name="image" class="btn btn-primary">

daj

<input type="hidden" name="MAX_FILE_SIZE" value="1000000" />
<input id="image" type="file" name="image" class="btn btn-primary">
