Hi everyone, hi UncleCheese,

I'm using the dataObjectManager in a popup in my cms. My cms suposted to be like a blog, but instead of pages (blogmodule) I use dataobjects for a new post. It should be possible to post an url of a free mp3 file. No problem with just one url. But it would be nicer if the user is able to post more than one url, so the blog-article would show two or three seperate musicplayers, each with one mp3 file.

Would be fantastic if it would be possible to have a little plus-symbol or something to add more textfields in the pop-up for more urls.

Do you think that's possible, somehow?

Thank you for help!

Yup. You can do this with NestedDataObjectManager.

BlogArticle.php

class BlogArticle extends DataObject
{
// example fields.. use whatever you have.
static $db = array('Title' => 'Varchar(50', 'Date' => 'Date');

static $has_many = array ('AudioFiles' => 'AudioFile');

// example.. use whatever page contains your blogarticle objects.
static $has_one = array ('BlogHolder' => 'BlogHolder');

function getCMSFields()
{
return new FieldSet(
new TextField('Title'),
new DatePickerField('Date'),
new FileDataObjectManager(
$this,
'AudioFiles',
'AudioFile',
'MP3',
array('Title' => 'Title')
)
);
}
}

AudioFile.php

class AudioFile extends DataObject
{
static $db = array ('Title' => 'Title');
static $has_one = array (
'BlogArticle' => 'BlogArticle', 
'MP3' => 'MP3'
);

function getCMSFields()
{
return new FieldSet(
new TextField('Title'),
new FileIFrameField('MP3')
);
}
}

That should give you a FileDataObjectManager in your popup window that will allow you to add files to your BlogArticle.

Then on the template, you just need to do:

<% control AudioFiles %>
Listen to $Title
$MP3.Player
<% end_control %>

Hi UncleCheese,

thank you for your fast answer!! Unfortunately that's not exactly what I meant. I'm pretty new in SilverStripe so, sorry if I didn't explain my task correctly. I try to explain it with your excample. Your Blogpost is my subcategory (a holder for many dataobjects) the audiofile is my post (dataobject). This post contains a Title, Subtitle, LongText and the AudioFile. The audiofile suppost to be just a link to a different page, where you can get free and legal mp3s. So this file will stay on that server. Now I need this let's call it "addMoreAudioURLs"-funktion in the dialog for the dataobject or so. One post should be able to contain more than one link to audiofiles. But I don't want to have like ten textfields in the popup for more urls in default.

Probably I need a JavaScript to disable more textfields in defaultmode...

Cheers,

Well then that's a much easier problem.

BlogArticle.php

class BlogArticle extends DataObject 
{ 
// example fields.. use whatever you have. 
static $db = array('Title' => 'Varchar(50', 'Date' => 'Date');

static $has_many = array ('AudioLinks' => 'AudioLink');

// example.. use whatever page contains your blogarticle objects. 
static $has_one = array ('BlogHolder' => 'BlogHolder');

function getCMSFields() 
{ 
return new FieldSet( 
new TextField('Title'), 
new DatePickerField('Date'), 
new DataObjectManager( 
$this, 
'AudioLinks', 
'AudioLink',  
array('Title'=>'Title','URL' => 'URL') 
) 
); 
} 
}

AudioLink.php

class AudioFile extends DataObject 
{ 
static $db = array ('URL' => 'Varchar(100)','Title' => 'Text'); 
static $has_one = array ( 
'BlogArticle' => 'BlogArticle'
);

function getCMSFields() 
{ 
return new FieldSet(
new TextField('Title'), 
new TextField('URL','Link to audio file','http://')
); 
} 
}

<% control AudioLinks %>
<a href="$URL">$Title</a>
<% end_control %>

Hello UncleCheese,

thank you so much! Great! It took a while till I understood what you mean (newbie-problem I guess), but after watching your video about nested DataObjectManager and reading your post again I got it.

Perfect, thats exactly what I need and it's so simple!!

Cheers,

Great to hear that!

FYI for anyone reading this thread.. there's a typo in the code above. class AudioFile should read "AudioLink".
