Question

i am trying to rewrite few requests into one batch request

$posts = $facebook->api('/me/feed?limit=9999999');

for($i = 0; $i < count($posts['data']); $i++)
{

  $comments = $facebook->api($posts['data'][$i]['id'].'/comments');
  $likes = $facebook->api($posts['data'][$i]['id'].'/likes');

}

Into

$batch = array();

$req = array(
    'method'       => 'GET',
    "name" => "prispevky",
    'relative_url' => '/me/feed',
);

$batch[] = json_encode($req);


$req = array(
    'method'       => 'GET',
    'relative_url' => '{result=prispevky:$.data.*.from.id}/comments'
);

$batch[] = json_encode($req);

$req = array(
    'method'       => 'GET',
    'relative_url' => '{result=prispevky:$.data.*.id}/likes'
);

$batch[] = json_encode($req);        

$params = array(
    'batch' => '[' . implode(',',$batch) . ']'
);

try 
{
  $info = $facebook->api('/','POST',$params);
  print_r($info);  
} 
catch(FacebookApiException $e) {
    error_log($e);
    $info = null;
}

But i recieve error 404 Some of the aliases you requested do not exist and then list of all id of feeds on the wall. When i call just one by simple request, i will recieve it succesfully.
Can someone help me and tell where do i have an error?

Answer 1

Henry Try this with loop to $Comments & $Likes
“This will return the Comments and Likes from post data 0. For each post beyond that you have to add a new array. I seen how you are trying to loop the array request, i have never been able to get that method to work since comments and likes exist in a separate table so to speak.”

NOTE: Batch only accepts a max of 20 requests, so requesting 999999 posts to loop will still only return the first 19 set of comment / likes given the first request is the post.

$queryProfileFeed = array(
        array('method' => 'GET', 'relative_url' => '/me/feed?fields=id%26'.$app_access_token.'' 'name' => 'getLnC', 'omit_response_on_success' => false),    
        array('method' => 'GET', 'relative_url' => '/{result=getLnC:$.data.0.id}/comments?fields=id%26offset=0'),
        array('method' => 'GET', 'relative_url' => '/{result=getLnC:$.data.0.id}/likes?fields=id%26offset=0'),
);
$batchResponse = $facebook->api('?batch='.json_encode($queryProfileFeed), 'POST');
        /* json decode response for comments */
    $Comments = json_decode($batchResponse[1]['body'], true);
        /* json decode response for likes */
    $Likes = json_decode($batchResponse[2]['body'], true);

I use the above method but with alot more batch request to show my wall in my plugins

but i only request the first 2 comments and likes from the first 10 posts. More than that seems to degrade performance and often timeout throwing errors like “alias does not exsist”
