Random Post Widget for Blogger

Random Post Widget for Blogger blogs. A simple way to display arbitrary posts from your blog's archives. This widget comes with loads of customizable options which can be easily configured using the Widget Generator found later. This is inspired from Aneesh Joseph's Random Post Gadget using the Blogger API. That gadget failed unexpectedly sometimes due very large iFrame URLs and the browser's incapability to render them. So I tweaked and converted it into a purely json based widget with no chance of that kind of failure occurring

Demo

Note : There is some problem with GoogleCode as of now which might have rendered the widget useless. To solve this problem , Open up the HTML/JavaScript widget and replace the following line
<script style='text/javascript' src='https://stylifyyourblog1.googlecode.com/svn/trunk/random.js'></script>


Change it with
<script style='text/javascript' >

    Some Tips
  • To make it look even more engaging to your readers, you can label it as "Posts being Viewed Currently" . It will make your readers believe that other people are viewing these posts and will drive more traffic to those posts.


  • After adding the widget you can simply change the settings from the Layout Tab itself or you can create another widget from the above Widget Generator and add it to your blog again. Make sure to delete the previous widget in that case.




  • If you Liked this Widget, Please Share it with fellow Blogger users.

    Please leave your opinions and suggestions so that we can make this widget even better. Feel free to share any problem you face while using it so that we can solve it at the earliest

    I am just wondering why someone will need random posts to be displayed rather than related posts. Am I missing something?

    Prayag Verma said...

    Hi Sabyasachi

    This kind of widget can be useful if your blog has hundreds of posts. As you can't practically promote all the older post to your readers so this can become a passsive way to direct them to those old posts

    how do i get the widget?

    Prayag Verma said...

    Hi Chrissy

    In the Widget Generator above , choose the options and then Click the Add Widget to My Blog button

    Was forced to replace the old Aneesh gadget, so thanks a lot for your effort.

    My other random blog gadget had errors and I had to replace it. The Random blog post viewer increases my page views significantly. I am very happy to have this back on my blog.

    Thank you so much.

    Thanks..

    matt said...

    Having the post title display to the right of the image thumbnail rather than on top would make this the holy grail of blogger random posts gadgets. I will wait patiently.

    vinod said...

    can this be done with a grid layout ?

    Luc Fayard said...

    Thank's very much! Is it possible to display all the post text without length limit?

    JP Hilton said...

    Great widget! I totally used it :)

    If you create any future versions, it would be cool if there was an option for horizontal display in addition to the vertical. This would work well for banner shaped widgets... just an idea :)

    Thanks again,

    Ary_Putra said...

    accurate information and good. with the above information we can add random post widget. I love being able to find a new way in our opinion.

    Em Ji Madhu said...

    Can we integrate this with a Specific Label? For example can we integrate with this code? Because this code displays in a ordered manner, i want it to display random posts.

    http://pastebin.com/z35NJksU

    thank you very useful information and gadget.

    help me, I can't apply this

    Awesome widgets! Keep it up..
    Bloggers are expecting this types of widget. Thanks.. :)

    hi Prayag Verma,

    I was Just Wondering If it is possible to do few Changes to this widget and make it advance.

    1. Add Another Option to Show Random posts from Different blogs.

    2. And to Show Second or third image from posts to show up in thumbnails.
    (Like add a option "get the Second image from each post or Third Image from each posts)

    I would very much like to Add something like that to by blog if it is doable.

    Рααм said...

    I can't make it work. Maybe 'cause my blog is private?

    Bookmarked You.

    Really Great. Keep it up.

    Rahul Sharma said...

    nice post thaanks.. techiee9

    The demo works great but I get an empty widget when adding this to my blog. I typed in sample content because Blogger states it won't accept an empty widget. I was expecting the widget to produce a lot of code automatically but it didn't. Am I missing something?

    Turan R said...

    HI Prayag,
