Caiken Posted December 4, 2014 Share Posted December 4, 2014 I am trying to use Cosenary's Instagram Class which is located at..https://github.com/cosenary/Instagram-PHP-APISpecifically, I am trying to do Pagination with a Tag Search. I want it to loop the process until it reach's yesterday's posts. I will run this script daily. <?php /** * Instagram PHP API * * @link https://github.com/cosenary/Instagram-PHP-API * @author Christian Metz * @since 01.10.2013 */ require '../dbinclude.php'; require 'Instagram.php'; use MetzWeb\Instagram\Instagram; // initialize class $instagram = new Instagram(array( 'apiKey' => '***************', 'apiSecret' => '***************', 'apiCallback' => '*************' // must point to success.php )); ?> <?php $i = 0; $imagecount = 0; do { $i++; echo "Pagination restart"; $photos = $instagram->getTagMedia('kittens'); $result = $instagram->pagination($photos); foreach($result->data as $post) { $image = mysqli_real_escape_string($toolconn, $post->images->low_resolution->url); $caption = mysqli_real_escape_string($toolconn, $post->caption->text); $author = mysqli_real_escape_string($toolconn, $post->user->username); $created = mysqli_real_escape_string($toolconn, $post->created_time); $created = date("Y-m-d H:i:s", $created); $compare = substr($created, 0, 10); $twodays = date("Y-m-d",strtotime("-2 days")); $link = $post->link; // echo $twodays . "<br>"; echo $compare . "<Br>"; $sql = "INSERT INTO userfeeds (link, thumbnail, created_at, caption, author) VALUES ('$link', '$image', '$created', '$caption', '$author')"; // $exec = mysqli_query($toolconn, $sql); echo $sql . "<br>"; echo "Created; " . $compare . "<BR>"; echo "Comparison; " . $twodays . "</br><hr>"; } } while ($compare != $twodays); ?> I have been trying to do this for about three weeks now. For some reason, my loop doesnt work. Help!In the documentation it says the following.. Each endpoint has a maximum range of results, so increasing the limit parameter above the limit won't help (e.g. getUserMedia() has a limit of 90). That's the point where the "pagination" feature comes into play. Simply pass an object into the pagination() method and receive your next dataset: <?php $photos = $instagram->getTagMedia('kitten'); $result = $instagram->pagination($photos); ?> Iteration with do-while loop. Basically my end goal is to make sure everyday I didnt miss a post.. I have been trying to work on this for literally three weeks and I have gotten nowhere Quote Link to comment https://forums.phpfreaks.com/topic/292878-instagram-api-pagination/ Share on other sites More sharing options...
QuickOldCar Posted December 9, 2014 Share Posted December 9, 2014 Since nobody ever replied to this will try to help a little. Specifically, I am trying to do Pagination with a Tag Search. You don't want to change the class, instead you want to use your already scraped data with a search and pagination. I want it to loop the process until it reach's yesterday's posts What if was more than 90 results for that specific search term? If instagram api has a from startrow or a way to query by date can take advantage of that From what I see is a max 90 results anything you searched for, such as your kitten The $i variable is used as a count but not really doing anything. It could potentially be used as a pagination on just the results got back from the live api, but in this instance you are saving them all to a database so is worthless. You can call to the script using single GET requests...coming from an array or lists you create somehow and here is a way can do that //add whatever want to the array $fetch_terms = array("kitten","dog","cat","funny","animal","penguin","horse","donkey"); shuffle($fetch_terms);//randomize it if(isset($_GET['fetch']) && trim($_GET['fetch']) != ''){ $fetch_term = trim($_GET['fetch']); } else { $fetch_term = $fetch_terms[0]; } then edit this line to $photos = $instagram->getTagMedia($fetch_term); now if call to the script with something like mysite.com/instagram.php?fetch=kitten it will retrieve kitten results if don't use the fetch query parameter in the url it would use a random one from the $fetch_terms array to handle ensuring getting them all, well unless you can query instagram a certain date, will just get latest ones, I never personally looked at their api but you could just run it as often as like, and set unique constraints in your database on 1 or more columns to ensure duplicates are not added $link = $post->link; looks like a good item to make it unique the command to do this for mysql ALTER TABLE userfeeds ADD UNIQUE (link); I will run this script daily. Unless you wanted just kittens,you need to run this many times a day on every fetch term you used in the script. $caption data could be used for your search later on, but you could also make a new column and use the $fetch_term you specify as a category/tag system This way is no need to search but instead can make the categories and a click will get you all those results...or have both. A combination search and pagination is very possible once you have the data stored mysql. Make a simple search form I suggest looking at this old mysql_ function pagination tutorial Mac_Gyver was so nice as to make a combo mysql/mysqli one http://forums.phpfreaks.com/topic/291074-php-mysli-pagination-with-items-per-page-select-option/?do=findComment&comment=1491152 Depending what you do with categories or can use fulltext search (which takes a bit of work,such creating an index in mysql) or do a LIKE in the sql query Since people do not do single words all the time, you would need to explode them by spaces For fulltext is a few different types of advanced searches and operators, take a look at boolean mode Example fulltext in boolean mode $sql = "SELECT * FROM userfeeds WHERE MATCH (caption) AGAINST ('$search_term' IN BOOLEAN MODE) Limit $offset, $rowsperpage"; Example LIKE sql $sql = "SELECT * FROM userfeeds WHERE caption LIKE '%$search_term%' LIMIT $offset, $rowsperpage"; The count sql also needs to be modified..minus the limit with offset and rows per page $sql = "SELECT COUNT(*) FROM userfeeds WHERE caption LIKE '%$search_term%'"; Now that's all fine for the search aspect and pagination, but should also make multiple sql queries if nothing was searched for so can do all results $search_term needs to exploded by spaces if multiple words, LIKE needs multiple where/and/or clauses while fulltext are spaced or use the + operator or others Untested code using my search integrated into mac_gyvers pagination with some changes <?php //configuration define('SOURCE','mysqli'); // the method/type of data source - mysql, mysqli //database $db_server = "localhost";//sever name, usually localhost $db_user = "username";//mysql username $db_pass = "password";//mysql password $db_database "database_name";//mysql database $tablename = "userfeeds"; //set table name for query $column = "caption"; //set column name for query $fulltext_search = false; //like or fulltext ...determine what type of search method, fulltext requires creating an index //end configuration $search_query = '';//leave blank switch(SOURCE){ case 'mysql': // database connection info $conn = mysql_connect($db_server,$db_user,$db_pass) or trigger_error("SQL", E_USER_ERROR); $db = mysql_select_db($db_database,$conn) or trigger_error("SQL", E_USER_ERROR); break; case 'mysqli': // database connection info $conn = mysqli_connect($db_server,$db_user,$db_pass,$db_database) or trigger_error("SQL", E_USER_ERROR); break; } if(isset($_GET['search']) && trim($_GET['search']) != ''){ $explode_search = array(); $search = trim($_GET['search']); $search = preg_replace('/\s+/', ' ', $search); $explode_search = explode(" ",$search); if($fulltext_search == true){ $trimmed_words = ''; foreach ($explode_search as $trim_words) { if (substr($trim_words, 0, 1) != "-" || substr($trim_words, 0, 1) != '"') { $trim_words = trim($trim_words); $trimmed_words .= " +$trim_words"; } else { $trim_words = trim($trim_words); $trimmed_words .= " $trim_words"; } }//end loop $trimmed_words = trim($trimmed_words); $trimmed_words = preg_replace('/\s+/', ' ', $trimmed_words); case 'mysql': $trimmed_words = mysql_real_escape_string($trimmed_words); break; case 'mysqli': $trimmed_words = mysqli_real_escape_string($conn, $trimmed_words); break; } //assembled search query $search_query .= "WHERE MATCH ($column) AGAINST ('$trimmed_words' IN BOOLEAN MODE)) "; } else { $multiple_like = array(); foreach($explode_search as $search_word){ switch(SOURCE){ case 'mysql': $search_word = mysql_real_escape_string($search_word); break; case 'mysqli': $search_word = mysqli_real_escape_string($conn, $search_word); break; } $multiple_like[] = "`$column` LIKE '%" . $search_word .
