Getting more than 20 Tumblr posts from a different website

Updated on May 29, 2014

Tumblr API only returns a limited number of posts, if you want to create a different section in your website to show your Tumblr posts then obviously you would want to show more than 20.

In this hub I'll show you a solution to this problem. Tumblr API's posts code accepts an offset parameter which is used when you want the posts to start from a different point rather than your last post. This parameter can be used to get more posts in your page.

What I did was that I created a Load More button, the user has to click it to load more posts. When it is clicked the whole fetching code is run again but this time with an offset.

Lets take a look at the JSON parsing code again.

$.ajax({ 
    type: 'GET', 
    url: 'http://api.tumblr.com/v2/blog/rofl-gifs.tumblr.com/posts?api_key=4k2NGQU1cJZ4d1ZqrvKR9mnpUUmubGPlyUEzDZfiL5loPeIOzv', 
    data: { get_param: 'value' }, 
    dataType: 'jsonp',
    success: function (data) { 
            console.log(data);
				for (i = 0; i <= 19; i++) {
					$('#results').append('<div style="text-align: center; border-top: 1px solid #aaa; width: 300px;"><a href="' + data.response.posts[i].post_url +'"> ' + data.response.posts[i].caption + '<img align="center" src="' + data.response.posts[i].photos[0].alt_sizes[0].url + '"></a></div><br/><br/>');
				}
    }
});

If you've read my previous hub. Then you know what every bit of the code does. But if you haven't then here's a summary of the above code's functions. For a complete overview please read my previous hub.

$.ajax() is a jQuery function using which we can fetch data from external sources in this case "Tumblr". This function requires five parameters:

  1. Type - What you want to do get data or post data in this case it's "GET"
  2. URL - Source of the data you want to receive.
  3. Data - The data you want to get from the source
  4. Data Type - Type of Data in this case jsonp
  5. Success - This accepts codes and functions which will be run upon success.

Getting More Than 20 Posts

As I previously wrote that we can use the offset parameter to load more posts. Here's my code:


	var o = 0;
	
	$('.load').click(function() {
		o += 20;
		$.ajax({ 
			type: 'GET', 
			url: 'http://api.tumblr.com/v2/blog/rofl-gifs.tumblr.com/posts?api_key=4k2NGQU1cJZ4d1ZqrvKR9mnpUUmubGPlyUEzDZfiL5loPeIOzv&offset=' + o, 
			data: { get_param: 'value' }, 
			dataType: 'jsonp',
			success: function (data) { 
				console.log(data);
					for (i = 0; i <= 19; i++) {
						$('#results').append('<div style="text-align: center; border-top: 1px solid #aaa; width: 300px;"><a href="' + data.response.posts[i].post_url +'"> ' + data.response.posts[i].caption + '<img align="center" src="' + data.response.posts[i].photos[0].alt_sizes[0].url + '"></a></div><br/><br/>');
					}
			}
});
	});
Load button on the page
Load button on the page

Explanation

I've place a button on the page which says "Load More" and has the class "load". The first line of this code declares a variable which has a value of 0.

var o = 0;

When the user clicks the load button a set of code is run.

$('.load').click(function() {

First this code adds 20 to the o variable and then runs the ajax() function of jQuery with the url containing an offset. The value of offset is the value of variable 'o', so the posts returned are started from where the lasts posts ended. e.g. 20 posts are loaded by default, from the last post to 19 previous posts, like if you have 60 posts then the posts from 60 to 40 are loaded by default and when the load button is pressed it runs the same fetching code to load posts from 40 to 20. As I wrote in my previous hub you can use the limit function to change the number of posts returned but then you will have to change the number being add to variable o so the posts returned are correct.

After fetching these posts on success theres a for loop which runs through the posts and adds the post url, post text and image into the page.

for (i = 0; i <= 19; i++) {
$('#results').append('<div style="text-align: center; border-top: 1px solid #aaa; width: 300px;"><a href="' + data.response.posts[i].post_url +'"> ' + data.response.posts[i].caption + '<img align="center" src="' + data.response.posts[i].photos[0].alt_sizes[0].url + '"></a></div><br/><br/>');
}

The more you press the button more posts are loaded. You can also create a paged system which I'll explain in my next hub.

      Sorry for replying so late. Can you please be more clear. Are you talking about posts with multiple pictures?

      By adding to you're original code, I allow the photos to be collected and then appended to the post div.

      Great article.

      Any idea how I could you get the number of photos in one post and then use it in a for loop to append the photos within the main loop?
