You can try elgg_get_entities_from_metadata(); 

Use same parameters as in your first example, and add 'metadata_name_value_pairs' or 'metadata_names' and 'metadata_values'. File plugins stores type as 'simpletype' metadata

Dear Ismayil,

Many thanks for your reply. So the code needs to be like below

$content_menu .= elgg_echo('file');
$content_menu .= ' (';
$content_menu .= elgg_get_entities(array(
'types' => 'object',
'subtypes' =>  array('file'),
'metadata_name_value_pairs' => array(array('name' => 'simpletype', 'value' => 'image')),
 'owner_guids' => page_owner_entity()->guid,
'full_view' => false,
'view_toggle_type' => false,
'count' => true
));
$content_menu .= ')';

But it is showing all counts , documents + images + videos please help

User the correct getter function elgg_get_entities_from_metadata();

@Ismayil

Yes i used like below

$fff = elgg_get_entities_from_metadata(array(
'types' => 'object',
'subtypes' =>  array('file'),
'metadata_name_value_pairs' => array(array('metadata_names' => 'simpletype', 'metadata_values' => 'image')),
'owner_guids' => page_owner_entity()->guid,
'full_view' => false,
'view_toggle_type' => false,
'count' => true
));

But still there is no use, could you please provide a sample code .. Please

Dear Ismayil,

Many thanks for your time and helping me on this. Atlast we got it. Please check my below working code

WOW your words worked atlast sorry the below code is the correct format, i added metadata_ instead of only names and values...

$fff = elgg_get_entities_from_metadata(array(
'types' => 'object',
'subtypes' =>  array('file'),
'metadata_name_value_pairs' => array(array('name' => 'simpletype', 'value' => 'video')),
'owner_guids' => page_owner_entity()->guid,
'full_view' => false,
'view_toggle_type' => false,
'count' => true
));

I am glad it worked. FYI,  full_view and view_toggle_type are of no use unless you are using elgg_list_entities_

Dear Ismayil,

Could you please let me know on how to display only FILE >> Video activity streams

I got this

<?php
                    
                      $num_items = $vars['entity']->num_items;
                      if (!isset($num_items)) $num_items = 12;
                    
                    
                      $widgtet_datas = elgg_view_river_items(0, $widget_group, '', 'object', 'file', '', $num_items,0,0,false);
                    
                    ?>       
                   
                    <div class="contentWrapper">
                      <?php
                          if(isset($widgtet_datas)) {
                              echo $widgtet_datas;
                          }
                      ?>
                  

But this will show all file subtypes like image, contents, videos etc. If there is any method for us to show only the videos? If so please help me
