How to build voting Ajax system with Codeigniter part 2.

Hi, my fulfilling friends coming back from marriage vacation with most interesting and full passion, so I hope to make this tutorial as a gift to all followers.

I thought to complete the previous tutorial about how to create voting system or poll system from A to Z,is this sounds good?

I will also provide the full script for free, is this enough?

I will show you steps by video, and I am ready for any question, let's start.

Script features

1- voting choices is dynamic :

You can add or remove vote choices as you want, range between 1 to 10 choices for a single vote, all stores in the database

2-all votes dynamically managed:

you can add unlimited votes, edit or remove.

3-votes restricted by IP address:

To avoid votes duplicating and prevent fake voters this script uses IP address to identify voters, save their IP's in a separate table.

4- Jquery AJAX supported:

The voting process sends by AJAX, results displayed immediately, also in the backend you have the ability to add or remove choices without reloading the page by using Jquery.

5-easy to install, simple to reuse:

Code designed to be clean as possible, separated to simplify reusing and for customization purposes.

6- integrated with the bootstrap framework.

7- free to use for non-commercial or commercial projects.

 

How to install

1- Extract downloaded zip file into root As example www or htdocs

2- Rename project to 'codeIgniter-voting '

3- Create new database named as 'demo

4- Import tables files from this path application/tables to the database.

5-Go to this link Http:://locahost/codeIgniter-voting

  Enjoy dude :)

Understand the logic and do it anyway

      hi dev yes that is alright , because voting is empty,you should go to the back end link and add voting to show it in the front end also you go to the wrong link ,the right link is http://localhost/codeIgniter-voting/admin_voting/
