Get Photos from Instagram via PHP

PHP code samples of getting media from Instagram by a username or by a tag. With new API support.

November 2, 2015 / #APIs, #Instagram

Of course, such lightbox viewers like Fancybox can be easily used if you get Instagram feed via JavaScript as well.

As for me, the JavaScript method has two major advantages.

  • Asynchronous AJAX requests do not affect on website response time. cURL in PHP does.
  • If you use PHP cache (for example WP Super Cache plugin for WordPress), the JavaScript method allows you to avoid feed caching.

Ok, so, the post is about PHP connection to Instagram API, isn’t it? :)

Step 1. Prepare. Function to set up cURL connection to Instagram API #

First of all you have to insert this function somewhere into your code, otherwise none of the following examples will work. If you use WordPress insert the function to your current theme functions.php file.

function rudr_instagram_api_curl_connect( $api_url ){
	$connection_c = curl_init(); // initializing
	curl_setopt( $connection_c, CURLOPT_URL, $api_url ); // API URL to connect
	curl_setopt( $connection_c, CURLOPT_RETURNTRANSFER, 1 ); // return the result, do not print
	curl_setopt( $connection_c, CURLOPT_TIMEOUT, 20 );
	$json_return = curl_exec( $connection_c ); // connect and get json data
	curl_close( $connection_c ); // close connection
	return json_decode( $json_return ); // decode and return
}

Step 2. Still Prepare. Instagram Access Token #

Instagram API doesn’t work with Client ID anymore, now every API connection requires Access Token.Do not be afraid — you can easily get it using this tool.

Step 3. Get posts / photos from Instagram #

According to the new Instagram API changes, until you approve your application you can get only the latest 20 media of youself. It means that only the one example from this post will work good and only if you specify your own username.

If you don’t want to deal with the code and access tokens, you can download ready to use plugin for WordPress. It doesn’t require an access token and has no restrictions.

By a tag #

As we want to use Fancybox plugin (or another lightbox) we should place the URL to the maximum size image into the link href attribute — $post->images->standard_resolution->url contains the URL to 612×612 image (the max resolution in Instagram).

$access_token = 'YOUR ACCESS TOKEN';
$tag = 'wordcamprussia2015';
$return = rudr_instagram_api_curl_connect('https://api.instagram.com/v1/tags/' . $tag . '/media/recent?access_token=' . $access_token);
 
//var_dump( $return ); // if you want to display everything the function returns
 
foreach ( $return->data as $post ) {
	echo '<a href="' . $post->images->standard_resolution->url . '" class="fancybox"><img src="' . $post->images->thumbnail->url . '" /></a>';
	/*
	$post->images->standard_resolution->url - URL of 612x612 image
	$post->images->low_resolution->url - URL of 150x150 image
	$post->images->thumbnail->url - URL of 306x306 image
 
	$post->type - "image" or "video"
	$post->videos->low_resolution->url - URL of 480x480 video
	$post->videos->standard_resolution->url - URL of 640x640 video
 
	$post->link - URL of an Instagram post
	$post->tags - array of assigned tags
	$post->id - Instagram post ID
	$post->filter - photo filter
	$post->likes->count - the number of likes to this photo
	$post->comments->count - the number of comments
	$post->caption->text
	$post->created_time
 
	$post->user->username
	$post->user->profile_picture
	$post->user->id
 
	$post->location->latitude
	$post->location->longitude
	$post->location->street_address
	$post->location->name
	*/
 
}

By a username #

Instagram API allows to get user feed only by a user ID. It can mean only the one thing — we should get the User ID at first.

$access_token = 'YOUR ACCESS TOKEN';
$username = 'rudrastyh';
$user_search = rudr_instagram_api_curl_connect("https://api.instagram.com/v1/users/search?q=" . $username . "&access_token=" . $access_token);
// $user_search is an array of objects of all found users
// we need only the object of the most relevant user - $user_search->data[0]
// $user_search->data[0]->id - User ID
// $user_search->data[0]->first_name - User First name
// $user_search->data[0]->last_name - User Last name
// $user_search->data[0]->profile_picture - User Profile Picture URL
// $user_search->data[0]->username - Username
 
$user_id = $user_search->data[0]->id; // or use string 'self' to get your own media
$return = rudr_instagram_api_curl_connect("https://api.instagram.com/v1/users/" . $user_id . "/media/recent?access_token=" . $access_token);
 
//var_dump( $return ); // if you want to display everything the function returns
 
foreach ($return->data as $post) {
	echo '<a href="' . $post->images->standard_resolution->url . '" class="fancybox"><img src="' . $post->images->thumbnail->url . '" /></a>';
}

Returned Values #

Both /users/{ID OF A USER}/media/recent and /tags/{NAME OF A TAG}/media/recent return the same array of objects. View the examples above.
