Hello,
I used NivoSlider, it's really easy to use: http://nivo.dev7studios.com/

To extract the contents, just create a content type with an images field and extract it on the homepage view as follows:

Code:

$teasers = find('Teasers')->limit(10)->order_by('date_update', 'DESC')->get();

foreach ($teasers as $teaser) {
    $imgs = $teaser->get('teaser_image'); //images field
    $path = $imgs[0]->path; //the first image
    echo '<img src="' . $path . '" />'; //prints the image
}

Hello, did you declared the image field like this:
http://docs.getbancha.com/content-types/...mages.html

If yes, the problem is that you need to check the number of elements in $img before calling an attribute of a null object:

Code:

$imgs = $teaser->get('teaser_image'); //images field
if (is_array($imgs) && count($imgs)) {
    $path = $imgs[0]->path; //the first image
    echo '<img src="' . $path . '" />'; //prints the image
}

Are you sure that you created at least one record of type "Teaser" with an image from the administration?
If yes, you can try to check what the record contains (into the foreach cycle) like this:

Code:

debug($teaser);
//or...
debug($teaser->get('your_image_field_id'));

[eluser]kkzhi[/eluser]
still cant get the teaser_image property in the xml

its always return a null value with debug($record->get('teaser_image')); but if i change into other field name it return a result

can somebody help?

[eluser]areesto[/eluser]
hi kkzhi,

i think you need to add this line :
$record->set_documents(); before this one $record->get(‘teaser_image’);

hope it work
