name="params['checkedImage']"

$vars['entity']->checkedImage is your widget's metadata that stores an array of selected guids.

Hi Khayredinov,

I tried the way as you sugested, but it did not worked.The $vars['entity']->checkedImage was alwas giving back an empty array. So what I did it in another way: 

1. I kept the form structure as it was in edit.php :

 echo "<tr><td>";

          echo elgg_view_entity($im);

          echo "</td><td>";          

          echo "<input value='checkedImage' name='params[".$im->guid."]' type='checkbox' />";

 echo "</td></tr>";

2. I got the checked images guid in this way:

   $filtered_psettings = 0;

           $entity = $vars['entity'];

           $psettings = get_all_private_settings($entity->guid);

           $filtered_psettings = array_keys($psettings, "checkedImage");

           $product_guids = array_values($filtered_psettings);

And I have now all the guids from the cehcked images in $product_guids but when I want to pass them to:  

$images = elgg_get_entities(array(

"type" => "object",

"subtype" => "image",

                "owner_guids" => $product_guids,

//"container_guid" => $guid,

"limit" => ELGG_ENTITIES_NO_VALUE,

                ));

and than in order to display them I use:

foreach ($images as $im){ 

the echo elgg_view_entity($im);

}

It is not returning anything. Even when I do var_dump($images->owner_guids); it is returning NULL. 

Do you have any suggestion why it is like this, why Elgg is reacting in this way?

All best!

I don't understand why are you using your image_guid array for owner_guids...

foreach ($product_guids as $im) {

elgg_view_entity($im);

}

You don't need to get an array of entities to display them. 

Thanks again for the help Khayredinov! I tried as you sugested. It did not worked eather. I realy dont understand how this whole thing works, or it is supposed to work. Here is again what I did :

<?php

$guid = (int) get_input('guid');
           $filtered_psettings = 0;
           $entity = $vars['entity'];
           $psettings = get_all_private_settings($entity->guid);
           $filtered_psettings = array_keys($psettings, "checkedImage");
           $product_guids = array_values($filtered_psettings);

           foreach ($product_guids as $im){

           echo elgg_view_entity($im);

           }

?>

At the end it returns "boolean false" which it seams that the values in $product_guid array are not an "instanceof ElggEntity". This are only the guids. But should the guids be an instance of ElggEntity? Sorry this might sound stupid question, but I am still trying to learn. Thanks for the help in advance!

What is the first place to look for an answer? Tidypics plugin:

1. tidypics/views/default/widgets/latest_photos

line 11: tp_get_latest_photos

2. tidypics/lib/tidypics

line 36: tp_list_entities

line 172: tp_view_entity_list

line 178:  $html = elgg_view('tidypics/gallery',array(

'entities' => $entities,

'count' => $count,

'offset' => $offset,

'limit' => $limit,

'baseurl' => $_SERVER['REQUEST_URI'],

'fullview' => $fullview,

'context' => $context,

'viewtypetoggle' => $viewtypetoggle,

'viewtype' => get_input('search_viewtype','list'),

'pagination' => $pagination

));

So pass your entity list to the elgg_view('tidypics/gallery') and see what happens
