Hi,
How to upload many files/images in one time.
In 2.4 i add UploadImages
In 3.0 i not idea how did this.

Now i build in gridfiles but to one entries i can attach one image :(

Someone can help?

EDIT

In ss3.demo i found like this "HasManyFilesUploadField" but i don't have idea how use it

Sorry for my bad English

the new UploadField does this for you.
If you have your relation set up on like this:

public static $has_many = array(
	'Images' => 'Image'
);

You can call UploadField and pass it the SS_List as argument:

$f = new UploadField('Images', 'Some images', $this->Images());
$fields->addFieldToTab('Root.Main', $f);

You can add some config to UploadField via setConfig to limit the number of file, the type and files and so on...

Thx for replay - it's workig - almost.

I do like you said.

Now I have like this:

Gallery.php

<?php 
class Gallery extends DataObject
{
    static $db = array (

    );
 
    static $has_one = array (
        'Attachment' => 'Image',
        'AsortymentyPage' => 'AsortymentPage'
    );
	
	static $belongs_many_many = array(
   );
	
	public static $summary_fields = array(
		
	);
	
	
	function getCMSFields() {
     return new FieldSet(
           new UploadField('Attachment')
     );
   }
}

AsortymentPage.php

...
static $has_many = array (
    	'Images' => 'Image'
    );
...
public function getCMSFields() {
    	$fields = parent::getCMSFields();
        $f = new UploadField('Images', 'Zdjęcia', $this->Images());
	$fields->addFieldToTab('Root.Galeria', $f);
		
        return $fields;
}
...

And i Backend and frontend like this (attach)

I think I made a mess in static has_many and has_one :)

When I give code:

static $has_many = array (
    	'Images' => 'Gallery'
    );

I have error.

Sorry for my bad English

AsortymentPage.php

change

static $has_many = array(
	'Images' => 'Image'
);

to

static $many_many = array(
	'Images' => 'Image'
);

then run:
/dev/build?flush=all
/admin/pages?flush=all

then logout and login again.

read http://www.silverstripe.org/general-questions/show/20246 for more details.

Might have missed it as I looked through the api docs, but is there a way to set the upload directory?

Any example working code would be great. I'm adding multiple images like in this thread.

Set upload directory in the SS3

$f = new UploadField('Images', 'Images');
$f->setFolderName($folder);

Perfect. Thanks.

One last thing as this is my first time working with SS3 and the UploadField.

After I have uploaded images, I can't edit or remove them from the page as seen here. http://shiftideas.com/uploads/ss-images_2f62.png

Is this normal or a bug? Using many_many relationship.

Sorry to hijack the thread.

to me this looks like a bug, I seen the same on my tests. The image file doesn't seem to be saved automatically in the right folder.
will probably need to investigates this a bit more. Maybe try the latest build on GitHub and see if it has been fixed?
