How to Create Automated Recent Posts Slider For Blogger - (FlexSlider)

In this article, today, we will try to create a dynamic and automated recent posts slider for blogger using Blogger JSON Feed and jQuery. We will also try to display recent posts of your blog inside FlexSlider which is a free slider plugin provided by woo themes. This slider gives a feeling of a tab widget where you can switch from one slide to another using the tab buttons or navigational controls. Keep in mind that WordPress users have already integrated recent posts inside flexslider but this is the first time blogspot, owned by Google, users will be able to display automatic list of recent posts inside an image slider.

In order to add recent post slider to your blogspot, you should follow these easy steps:
1.            Go To Blogger > Template
2.            Backup your template
3.            Then Click "Edit HTML"
4.            Just below <head> tag paste the following JS and CSS source links:

<script src='http://ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js' type='text/javascript'></script>
<link href='http://fortawesome.github.io/Font-Awesome/assets/font-awesome/css/font-awesome.css' rel='stylesheet'/>
<link href='http://fonts.googleapis.com/css?family=Oswald' rel='stylesheet' type='text/css'/>
<link href='https://cdnjs.cloudflare.com/ajax/libs/flexslider/2.6.1/flexslider.min.css' rel='stylesheet' type='text/css'/>
<script src='https://cdnjs.cloudflare.com/ajax/libs/flexslider/2.6.1/jquery.flexslider.min.js' type='text/javascript'></script>
Note: Do not add JQuery, FontAwesome or Oswald links in the code above to your template if you are already using them on your site.
5.            And now next search ]]></b:skin> and just above it paste the following code:
<style>

Make the following changes
6.            If you want to change the green color theme of the slider simply replace the green highlighted color codes with color of your own choice. The color can be in rgb or #hexadecimal, both can work. Use our  Color Code Generator.
7.            Save your template.
8.            Now go to Blogger > Layout
9.            Select "Add a Gadget"
10.          From the list of the gadget choose "HTML/JavaScript" gadget
11.          Keep the title field of "HTML/JavaScript" gadget  empty and then paste the following code inside it:

<script type="text/javascript">
  $(window).load(function() {
    $('.flexslider').flexslider({
   animation: "slide",
        directionNav: false,
       touch: true, 
       slideshowSpeed: 2500,
      pauseOnHover: true,
     animationSpeed: 700,
    });
  });

If you want to modify your widget, the following controlling options will help you, therefore, also follow these steps:
Animation: Select the type of your animation, "fade" or "slide"
Slideshow Speed: You can set the speed of the slideshow cycling, in milliseconds
Animation Speed: In animation speed, you can also set the speed of animations, in milliseconds
PauseOnHover: Pause the slideshow when hovering over slider, then resume when no longer hovering
You can change/edit the widget title by editing: Recent Posts Slider
Similarly if you don't want to use the title then delete the yellow highlighted code.
ListBlogLink : you can Insert your Blog link here
ListCount : Here you have the option to decide that how many posts do you wish to display. Choose even integer only like 2, 4, 6, 8, 10 etc.
ListLabel : Here you can insert your blog label/category. Keep notice that labels are case sensitive. Therefore type it exactly as it is shown in your browser address bar. If your label is "blogging tips" and if you type it as "Blogging Tips" then it won’t work. You must make sure that all letters are written in correct cases as it is shown in your browser address bar.
TitleCount: Here you can decide to choose how many characters to display in post title.
ImageSize : You can also control the resolution or aspect ratio of thumbnails by editing ImageSize = 150; where the value 150 means that you want your images to be within 150 x 150 pixels in size. Keep this value close to the thumbnail size to ensure website load time is not effected a lot. Since our thumbnail images have a width of about 110px, therefore we have kept the resolution as 150, slightly higher to display images in slightly good quality.
Remember here that if you want to show recent posts published on your blog but don't wish to display posts from a specific label then simply remove /-/"+ListLabel+" from the code above.
Click Save and you are all done!
Display Slider or Just a Flat List!
Here we have setup the logic such that you can choose whether to display your posts inside animated FlexSlider or display them as simple flat list similar to my earlier recent posts widget. In other words you can choose to enable or disable the FlexSlider.
How to enable or disable the flex slider?
This is extremely simple. If you want to display and enable FlexSlider then insert even integer value next to ListCount , such as 2, 4, 6,8, 10, 12 etc. The JavaScript logic above will divide your inserted value into two sections and will display posts in each slide accordingly.
Output will be such:




















displaying a dynamic Flat list or in other words to disable FlexSlider insert odd integer value next to, such as 1,3,5,7,9,11 etc.

Output will be such:
