youtube data api v3 php search pagination? - youtube

i am trying with youtube api v3 php search...
first time i'm using this api for this i am beginner...
i have 3 question;
1) how can below search list showing pagination numbers? (per page 50 result)
2) how can video duration show in list? (3:20 min:second)
3) how can order viewCount
if ($_GET['q']) {
require_once 'src/Google_Client.php';
require_once 'src/contrib/Google_YoutubeService.php';
$DEVELOPER_KEY = 'my key';
$client = new Google_Client();
$client->setDeveloperKey($DEVELOPER_KEY);
$youtube = new Google_YoutubeService($client);
try {
$searchResponse = $youtube->search->listSearch('id,snippet', array(
'q' => $_GET['q'],
'maxResults' => 50,
'type' => "video",
));
foreach ($searchResponse['items'] as $searchResult) {
$videos .= '<li style="clear:left"><img src="'.$searchResult['snippet']['thumbnails']['default']['url'].'" style="float:left; margin-right:18px" alt="" /><span style="float:left">'.$searchResult['snippet']['title'].'<br />'.$searchResult['id']['videoId'].'<br />'.$searchResult['snippet']['publishedAt'].'<br />'.$item['contentDetails']['duration'].'</span></li>';
}
$htmlBody .= <<<END
<ul>$videos</ul>
END;
} catch (Google_ServiceException $e) {
$htmlBody .= sprintf('<p>A service error occurred: <code>%s</code></p>',
htmlspecialchars($e->getMessage()));
} catch (Google_Exception $e) {
$htmlBody .= sprintf('<p>An client error occurred: <code>%s</code></p>',
htmlspecialchars($e->getMessage()));
}
}

1) how can below search list showing pagination numbers? (per page 50 result)
You need to write your own cacheing logic to implement this feature because with every result you get two tokens "NextPageToken" and "PreviousPageToken" and subsequent query must contain that token number to get next page or previous page token like below.
So whenever results are not available at cache then you should send either nextpagetoken or previous page token.
https://www.googleapis.com/youtube/v3/search?key=API_KEY&part=snippet&q=japan&maxResults=10&order=date&pageToken=NEXT_or_PREVIOUS_PAGE_TOKEN
In particular your case where you need 50 pages per page and you are showing 3 pagination like (1,2,NEXT) then you need to fetch results two times. Both the results you will keep in cache so for page 1 and 2 results will be retrieved from cache. For next you make it sure that you are making query google again by sending nextPageToken.
Thus to show pagination 1-n and every page 50 results then you need to make n-1 queries to google api. But if you are showing 10 results per page then you cane make single query of 50 results using which you can show first 5 pages (1-5) with the help of retrieved results and at next you should again send next page token like above.
NOTE- Google youtube api provide 50 results max.
2) how can video duration show in list? (3:20 min:second)
Youtube API v3 do not return video duration at simple first search response. To get video duration we need to make one extra call to youtube api like below.
https://www.googleapis.com/youtube/v3/videos?id=VIDEO_ID1%2CVIDEO_ID2&part=contentDetails&key=API_KEY (max 50 IDs)
This issue is highlighted in "http://code.google.com/p/gdata-issues/issues/detail?id=4294".I posted my answer here too.
Hence if we want to display video duration then we need to make two calls every time.
3) how can order viewCount
Trigger below query it will provide results ordered by view count.
https://www.googleapis.com/youtube/v3/search?key=KEY&part=snippet&q=japan&maxResults=5&order=viewCount
For detail please refer this - https://developers.google.com/youtube/v3/docs/search/list#order

The youTube API V3 is somehow complicated compare to API V2.
To the question above, my approach is not for search result rather is to retrieve user uploaded videos. I believe this can be useful
References
The way you create pagination in v3 is not the same as in v2 where you can make your call simply like
$youtube = "http://gdata.youtube.com/feeds/api/users/Qtube247/uploads?v=2&alt=jsonc&start-index=1&max-results=50";
In v3 you need to make two or three calls the first one will be to get the channel detail and second call will be to retrieve playlist from where we will get the channel playlist Id and finally retrieve individual video data.
I am using Php CURL
$youtube = “https://www.googleapis.com/youtube/v3/channels?part=snippet%2CcontentDetails%2Cstatistics&id=yourChannelIdgoeshere&key=yourApiKey”;
Here we retrieve user playlist ID
$result = json_decode($return, true);
$playlistId=$result['items'][0]['contentDetails']['relatedPlaylists']['uploads'];
we define pagetoken
$pageToken=’’;
Each time user click control button we retrieve pagetoken from session[] and feed the curl url, and in turn will produce nextpagetoken or prevpagetoken. Whatever you feed the url the Api know what set of list to populate.
if(isset($_REQUEST['ptk']) && $_REQUEST['ptk’]!==''){
$pageToken=$_REQUEST['ptk’];
}
Here we retrieve user playlist
$ playlistItems =”https://www.googleapis.com/youtube/v3/playlistItems?part=snippet&pageToken=”.$pageToken.”&maxResults=50&playlistId=$playlistId&key= yourApiKey”;
If user has more than maxResult, we should have nextPageToken, take for an example user has 200 uploaded videos,the first pagetoken may be CDIQAA and next pagetoken may be CGQQAA while previous may be CDIQAQ , something like that so is not a number.
Here we save the pagetoken
if(isset($result['nextPageToken'])) { $_SESSION[nextToken]=$result['nextPageToken'];
}
if(isset($result['prevPageToken'])) { $_SESSION[prevToken]=$result['prevPageToken'];
}
we can then create our control button <>
$next=$_SESSION[nextToken];
$prev=$_SESSION[prevToken];
The control button here
<a href=”?ptk=<?php echo $prev?>” ><<prev</a>
<a href=”?ptk=<?php echo $next?>” >next>></a>
From here when user click link it set either next or prev page in session variable (go to up to see how this work)
To get video duration we use same Php curl
$videoDetails="https://www.googleapis.com/youtube/v3/videos?part=id,snippet,contentDetails,statistics,status&id=videoIdHere&key=yourApiKey";
$videoData = json_decode($return, true);
$duration = $videoData['items'][0]['contentDetails']['duration'];
$viewCount = $videoData['items'][0]['statistics']['viewCount'];
you may get something like this ('PT2H34M25S')
I have answer a question Here which show you how to convert the duration data

YouTube API "ChannelSections" results don't match with channel?

So for the YouTube Channel Mindless Self Indulgence it has 4 sections on the home tab first section is they're music videos playlist, the 2nd section is albums which is a group of different playlists, then another playlist section and the last section is there uploads.
But when I do a channelSections api call I get like 20 different items and it has me scratching my head why.
Here's the api response https://notepad.pw/raw/w27ot290s
https://www.googleapis.com/youtube/v3/channelSections?key={KEYHERE}&channelId=UChS8bULfMVx10SiyZyeTszw&part=snippet,contentDetails
So I figured this out finally, I neglected to read the documentation on the channelSections api 😅
here: https://developers.google.com/youtube/v3/docs/channelSections
I was getting channel sections for all the regions where channel like music may more often have region specific sections... To filter these you need to also include the targeting object in the part parameter. If the section is region free (or atleast i assume) it won't have the targeting object so something to take into condertation when handling your api response and filter sectoins based on regions.
Here's my code just trying to get the data filtered in react app, not the most practical maybe but I fumbled through it:
const data = response2.data.items;
console.log("response2 data", data);
const filtered = data.filter(item => {
if (item.targeting === undefined) return true;
let test = false;
item.targeting.countries.forEach(i => {
if (i === "US") test = true;
});
return test;
});

Youtube Data API searching for all videos on a channel returns double results

I'm writing a PHP script that retrive all videos of a channel using Google APIs Client Library for PHP and youtube.search.list with params:
part = snippet
maxResults = 50
channelId = ...
type = video
order = rating
pageToken = [nextPageToken]
Scrolling all the results of pagination I see that sometimes the search returns videos that were present in the previous pages.
I have tested thoroughly and the calls to the next pages are correct with the right nextPageToke.

Accessing public Instagram content via Instagram API without expiring accesstoken

i want to show public contents from instagram related to a specific hashtag (everything works fine with that) but i can't to renew the access_token everytime it expires.
("do not assume your access_token is valid forever." -
https://www.instagram.com/developer/authentication/)
To renew it manually is not an option i have to make sure there is a valid access_token at ANY time without re-authenticating.
Any ideas or questions? :)
I have one idea, but without API (and access_token). You can make requests to the web-version of Instagram with ?__a=1 parameter. I do not know how long it will work but now there is workflow:
You want to show public content with hashtag space, for example.
Add it to url and add GET-parameter ?__a=1: https://www.instagram.com/explore/tags/space/?__a=1
Make the GET-request. It returns json with nodes in top_posts (8) and media (18). Each node has owner, caption, number of comments and likes. But the most important part is in thumbnail_src and display_src.
There is page_info in media object which helps to paginate results. You need end_cursor (for example, J0HWE9rjAAAAF0HWE9qvgAAAFiYA)
Add the value from end_cursor to the url: https://www.instagram.com/explore/tags/space/?__a=1&max_id=J0HWE9rjAAAAF0HWE9qvgAAAFiYA
Repeat 3-6 to get newest posts with specific hashtag.
Update to the ?__a=1 url param. This appears to have stopped working with users '/account/?__a=1' endpoints.:( Still works on tags apparently.
Instagram shut down their public API. Here's a quick and dirty workaround in PHP:
<?php
function getPublicInfo($username) {
$url = sprintf("https://www.instagram.com/$username");
$content = file_get_contents($url);
$content = explode("window._sharedData = ", $content)[1];
$content = explode(";</script>", $content)[0];
$data = json_decode($content, true);
return $data['entry_data']['ProfilePage'][0];
}
Not sure for how long it's gonna work. Here's one for Javascript.

Retrieving individual videos view count - Youtube API V3.0 - JavaScript

I've been trying to get the view count on videos that I query through the following method:
function search() {
var request = gapi.client.youtube.search.list({
part: 'snippet',
channelId: 'IRRELEVANT',
order: 'date',
maxResults: '25'
});
request.execute(function(response){
YoutubeResponse(response);
});
While the documentation tells me that there's a statistics portion to every video, after the snippet I have __proto__ which I guess means there was an error somewhere? or did the API change? Essentially I need the view count of those 25 most recent videos...
I tried changing part: 'snippet' to part: 'statistics' but got back a code: -32602...
Thanks for the help,
Cheers!
EDIT: Apparently the search.list doesn't have the "statistics" but rather I need to search every video individually... The thing is, when using googles "Try It" feature (https://developers.google.com/youtube/v3/docs/videos/list#try-it) when you ask for the statistics in the "Fields" part at the bottom, it doesn't do anything... So I am VERY confused as to how the heck can I get the view counts & length of all 25 videos (if individually or all at once - preferably-)
The link you gave https://developers.google.com/youtube/v3/docs/videos/list#try-it is working for me.
To get duration and viewCount: Fill in for part: contentDetails,statistics and for id: a comma-separated-list of video-id's like: TruIq5IxuiU,-VoFbH8jTzE,RPNDXrAvAMg,gmQmYc9-zcg
This will create a request as:
GET https://www.googleapis.com/youtube/v3/videos?part=contentDetails,statistics&id=TruIq5IxuiU,-VoFbH8jTzE,RPNDXrAvAMg,gmQmYc9-zcg&key={YOUR_API_KEY}
Agree with the answer provided by #Als.
But I found a code snippet which might be more convenient for some of you:
function youtube_view_count_shortcode($params)
{
$videoID = $params['id']; // view id here
$json = file_get_contents("https://www.googleapis.com/youtube/v3/videos?
part=statistics&id=" . $videoID . "&key=xxxxxxxxxxxxxxxxxxxxxxxx");
$jsonData = json_decode($json);
$views = $jsonData->items[0]->statistics->viewCount;
return number_format($views);
}
Replace the key value with the google api key for youtube data API and the video id with the youtube video id and Voila you get the total number of views for the youtube video.

Retrieving Data in a While Loop from the Youtube API

I do have a hughe database where some data sets link to certain youtube videos. As we all know some youtube videos disappear after a while from youtube and this leads to my solution and my problem as well --> I'd like to check if the youtube video still exists by simply checking via JSON if there is data to retrieve from a video. If not than I'd simply delete that certain data set.
So the first part of my solution would be to go through each row of my data table and checking for each id if there is data to retrieve from youtube as seen in the following code:
$result = $db->query("SELECT id, link FROM songs");
while($row = $result->fetch_assoc())
{
$number = 1+$rown++;
$id = $row['id'];
$link = $row['link'];
$video_ID = $link;
$JSON = file_get_contents("https://gdata.youtube.com/feeds/api/videos/{$video_ID}?v=2&alt=json");
$JSON_Data = json_decode($JSON);
$views = $JSON_Data->{'entry'}->{'yt$statistics'}->{'viewCount'};
echo $number .' row<br />';
echo $link .' link<br />';
echo $views .' views<br /><br />';
}
This attempt works fine and outputs me the data I need. The only problem is, that it just gets me data from the first 150-190 rows and that's it. Now I am checking for a solution that checks each row for empty youtube data and this lead to two concrete questions I have:
1st) Might youtube be responsible for that due to a restriction in retrieving data from one single query?
2nd) Might this be a server issue of mine that stops queries after x-seconds (but I already expand the time limit by putting a line set_time_limit (10000000); into my php code but without success)?
Hope you can help, thanks in advance.
YouTube, naturally, enforces limits on how many requests you can make per period of time. Unfortunately, there are no clear guidelines on what those limits are ... for v2, the guidelines merely state:
The YouTube API enforces quotas to prevent problems associated with
irregular API usage. Specifically, a too_many_recent_calls error
indicates that the API servers have received too many calls from the
same caller in a short amount of time. If you receive this type of
error, then we recommend that you wait a few minutes and then try your
request again.
If time isn't an issue for you, you could slow down each query so that you only make 1 request per every 10-15 seconds or so. Alternatively, you'd probably have better luck batch processing. With this, you can make up to 50 requests at once (this counts as 50 requests against your overall request per day quota, but only as one against your per time quota). Batch processing with v2 of the API is a little involved, as you make a POST request to a batch endpoint first, and then based on those results you can send in the multiple requests. Here's the documentation:
https://developers.google.com/youtube/2.0/developers_guide_protocol?hl=en#Batch_processing
Batch processing is much easier with v3, as you just have the videoId parameter be a comma delimited list of the videos you want info on -- so in your case, you'd execute file_get_contents on a URL like this:
https://www.googleapis.com/youtube/v3/videos?part=id&id={comma-separated-list-of-IDs}&maxResults=50&key={YOUR_API_KEY}
Any video ID in your list that doesn't come back in the JSON response doesn't exist anymore. IF you do 50 at a time, wait for 15 seconds, do another 50, etc., that should give you better performance.
