Question

I am new in php and I am trying to make a multiple image uploader. My form looks like this:

<form action="" method="post" enctype="multipart/form-data">
    <p class="style2">Izberi datoteko: <br /><input type="file" name="image" multiple="multiple" /></p>
    <p class="style2">
        Izberi Album: <br />
            <select name="album_id">
                <?php 
                    foreach ($albums as $album) {
                        echo '<option value="', $album['id'] ,'">', $album['name'] ,'</option>';
                    }
                ?>
            </select>
    </p>
    <p class="style2"><input type="submit" value="Naloži Slike" /></p>
</form>

And on the php side I did something like:

if (isset($_FILES['image'], $_POST['album_id'])) {
$image_name = $_FILES['image']['name'];
$image_size = $_FILES['image']['size'];
$image_temp = $_FILES['image']['tmp_name'];

$allowed_ext = array('jpg', 'jpeg', 'png', 'gif');
$a = explode('.', $image_name);
$image_ext = strtolower(end($a));

$album_id = $_POST['album_id'];

$errors = array();

if (empty($image_name) || empty($album_id)) {
    $errors[] = '<p class="style2">Nekaj manjka!</p>';
} else {

    if (in_array($image_ext, $allowed_ext) === false) {
        $errors[] = '<p class="style2">Izbrani tip datoteke ni dovoljen!</p>';
    }

    if ($image_size > 2097152) {
        $errors[] = '<p class="style2">Izbrana datoteka je prevelika! Maksimalna velikost datoteke mora biti 2mb!</p>';
    }           
}

if (!empty($errors)) {
    foreach ($errors as $error) {
        echo $error;
    }
} else {
    upload_image($image_temp, $image_ext, $album_id);
    header('Location: view_album.php?album_id='.$album_id);
    exit();
} 

}

I created a function that puts the image into database. This function looks like this:

function upload_image($image_temp, $image_ext, $album_id) {
$album_id = (int)$album_id;

mysql_query("INSERT INTO `images` VALUES ('', '". $_SESSION['user_id'] ."', '$album_id', UNIX_TIMESTAMP(), '$image_ext')"); 

$image_id = mysql_insert_id();
$image_file = $image_id.'.'.$image_ext;
move_uploaded_file($image_temp, 'galerija/'.$album_id.'/'.$image_file);

create_thumb('galerija/'.$album_id.'/', $image_file, 'galerija/thumbs/'.$album_id.'/');
}

This works fine for uploading only one image. I tried to create a form for multiple select files and i can select more images but in database only gets first image. I tried to put foreach() in my script but I don t know where and how I must put it in.
So how can i change my script so I can upload more images into my database? I just can’t figure it out. Any help would be great!

Answer 1

A. PHP would not be albe to see your multiple files like that

Replace

  <input type="file" name="image" multiple="multiple" />

With

 <input type="file" name="image[]" multiple="multiple" />

To loop over this files you need something like

foreach ( $_FILES['image']['tmp_name'] as $key => $val ) {

    $fileName = $_FILES['image']['name'][$key];
    $fileSize = $_FILES['image']['size'][$key];
    $fileTemp = $_FILES['image']['tmp_name'][$key];

    $fileExt = pathinfo($fileName, PATHINFO_EXTENSION);
    $fileExt = strtolower($fileExt);

    // Continue
}
