Hi,
I was trying to get banner images via mobile API and created an API for that.
Based on my understanding in blocks/banner_block.php it is calling func_get_arg(0) to get instance_id(It is returning exact instance_id what it has been saved in block_layouts_table for banner_block).
When I try it from my PHP file it is saying Argument 0 is not passed to func_get_arg.I think controller is playing role here.
Is it possible to get same instance_id what we get in banner_blocks.php file into my file?
Thanks in Advance.

what about to get it from hook?
for example:
public function onControllerBlocksBannerBlock_InitData(){
$instance_id = $this->baseObject->getInstance();
//var_dump($instance_id);
}
is it the same id?

Hi,
Thank you for reply.
Actually when I tried, I am getting error as call to member function getInstance() on null.
I can't find out the way to rectify it.
I have added my file here.
If i could get instance_id I can get banner_list.
Sorry I can't understand hook concept and how to use it.
class ControllerApiCommonBlocksBannerBlock extends AControllerAPI {
protected $registry;
public function onControllerBlocksBannerBlock_InitData()
{
$this->registry = Registry::getInstance();
$instance_id = $this->baseObject->getInstance();
//var_dump($instance_id);
}
public function get() {
$this->extensions->hk_InitData($this,__FUNCTION__);
$request = $this->rest->getRequestParams();
$controller="pages/index/home";
$this->layout->buildPageData($controller);
$instance_id=""; //have to get through hooking
$response=$this->getBlockContent($instance_id);
$this->extensions->hk_UpdateData($this,__FUNCTION__);
$this->rest->setResponseData( $response );
$this->rest->sendResponse( 200 );
}
public function getBlockContent($instance_id) {
$block_info = $this->layout->getBlockDetails($instance_id);
$custom_block_id = $block_info['custom_block_id'];
$this->loadModel('extension/banner_manager');
$results = $this->model_extension_banner_manager->getBanners($custom_block_id);
$banners = array();
if($results){
$rl = new AResource('image');
foreach($results as $row){
if($row['banner_type']==1){ // if graphic type
/**
* @var array
*/
$row['images'] = $rl->getResourceAllObjects('banners',$row['banner_id']);
//add click registration wrapper to each URL
//NOTE: You can remove below line to use tracking javascript instead. Javascript tracks HTML banner clicks
$row['target_url'] = $this->html->getURL('r/extension/banner_manager/click', '&banner_id='.$row['banner_id'], true);
} else {
$row['description'] = html_entity_decode($row['description']);
}
$banners[] = $row;
}
}
$output = array(
'content' => $banners
);
return $output;
}
}

mm..
All banners placed inside banner-block. This block can be placed in any placeholder of layout (see admin->design->layouts ).
There to many dynamical parameters. What if somebody had changed layout? Instance of block will be changed.
I think you should to
1. define is some banner-block enabled in some layout.
2. get it's block_id from blocks_layouts database table.
3. get banner block content from table block_descriptions
4. get all banner IDs from it's content (or banner group)
5. get all images of all banners

Hi,
Thank you,It is good idea indeed :).
I knew that instance_id is changed each time when layout has been saved.
I may need to write query for that to fetch instance_id by passing block_id.
That's why I chose to go with instance_id as it is fetched from blocks_layouts table on calling buildPageData() function.(That's how it works in web interface.)
However,I fetched banner images via Admin function.(The function which is used to populate list in banner_manager interface.)
can't we get instance_id from another file through hooking?
