Hi miteshsc, here how I will do this:

$options['metadata_name_value_pairs'] = array(
                array(
                        'name'  => 'action',
                        'value' => 'search'               
                ),
                array(
                    'name' => 'key',
                    'value' => '1234567'
                ),
            );
   
 $entities = elgg_get_entities_from_metadata($options);

 

Hey ElggCloud,

Thanks a lot. Cheers!

Now i am tryin to save another entity with different metadatas action=>"save" , key=>"1234567"  and i am passing same key(1234567) in title and description. but when i am trying fetch entity using

$options['metadata_name_value_pairs'] = array(
                array(
                        'name'  => 'action',
                        'value' => 'save'               
                ),
                array(
                    'name' => 'key',
                    'value' => '1234567'
                ),
            );
   
 $entities = elgg_get_entities_from_metadata($options);

it is giving me blank title and description, i dont know what's wrong here.

Help please!

What do you mean with "i am passing same key(1234567) in title and "description".   Can you paste your code here in order to see your problem.

$key = '1234567';

CASE 1:

$flock= new ElggFlock();
$flock->subtype = 'flock';
   
$flock->access_id = 2;
$flock->title = $key;
$flock->description = $key;
$flock->action = 'search';
$flock->key = $key;
   
if (!$flock->save()) {
  $error = elgg_echo('flock:error:cannot_save');
}

CASE 2:

$flock= new ElggFlock();
$flock->subtype = 'flock';
  
$flock->access_id = 2;
$flock->title = $key;
$flock->description = $key;
$flock->action = 'save';
$flock->key = $key;
  
if (!$flock->save()) {
  $error = elgg_echo('flock:error:cannot_save');
}

For a second case it not saving title and description. I dont know why. That i came to know when i am searching entity using metadatas.

$options['metadata_name_value_pairs'] = array(
                array(
                        'name'  => 'action',
                        'value' => 'save'              
                ),
                array(
                    'name' => 'key',
                    'value' => '1234567'
                ),
            );

$entities = elgg_get_entities_from_metadata($options);

It returns entity with blank title and description.

Ok, some remarks here:

• If  case 2 does not save ElggFlock entity, how can you expect that elgg_get_entities_from_metadata will find it:

$options['metadata_name_value_pairs'] = array(
                array(
                        'name'  => 'action',
                        'value' => 'save'              
                ),
                array(
                    'name' => 'key',
                    'value' => '1234567'
                ),
            );

 

• $entities is an arry of objects. Do you access it correctly? for example, if it returns only one object, then $entities[0] is this object.  Put some debug code to check this out:

$entities = elgg_get_entities_from_metadata($options);

echo 'Entities no: ' . count($entities). '<br>';
foreach($entities as $entity) {
     echo 'Guid: '.$entity->guid.' Title: '.$entity->title.' Description: '
      .$entity->description.'<br>';
 }

Also, you can just print out the entire object array:

print_r($entities);

• Check: use ElggObject instead of ElggFlock. This should create an ElggObject with subtype flock.  This because you might have a problem in your ElggFlock class itself.

Title and description are not metadatas
