Instagram API Wrapper class will help to create a base wrapper class for Instagram API request/response with OAuth.
You have to register yourself as developer at the Instagram Developer Platform and set up an App. Then use the credentials generated from the Instagram developer account in the wrapper class to call two class functions.
This class aims at handshaking with instagram by authenticating user (OAuth2) and then perform below functionalities.
1. Get images uploaded by instagram username
2. Get images uploaded based on the hashtags
usage:
//include instagram wrapper class
include "class.instagram_api_wrapper.php";
//Initialize the class
//create object of the main class
$obj=new instagram_api_wrapper();
//assign values to the Instagram clientid, secret, and redirect url
$obj->client_id='YOUR INSTAGRAM CLIENT ID';
$obj->secret='YOUR INSTAGRAM SECRET KEY';
$obj->redirect_url='YOUR APPLICATION REDIRECT URL';
//set media for the username - media will be returned for the username
//in case of SANDBOX ACCOUNT USE YOUR USERNAME
$search_by_username = 'USERNAME_YOU WISH TO SEARCH';
//set media for the hashtag - media will be returned for the hashtag
$search_by_tag ='business';
//Authenticate user (OAuth2)
//First step to get all the media file is to handshake with Instagram API - returns code
if(!isset($_REQUEST['code'])){
$obj->getInstagramCode($obj->client_id,$obj->redirect_url);
}
//once code is returned - authroise the API to get Token -this token will be used throughout the API request/response
if(isset($_REQUEST['code'])){
$code = $_REQUEST['code'];
//get token from Instagram
$access_token = $obj->authorizeAPI($code,$obj->client_id,$obj->secret,$obj->redirect_url);
//using token search media by username
echo '<br>Search by Username<br>';
print_r($obj->getInstagramMediaByUsername($search_by_username,$access_token));
//using token search media by hashtag
echo '<br>Search by Hashtag<br>';
print_r( $obj->getInstagramImagesByTag($search_by_tag,$access_token) );
