A simple Wordpress post voting plugin with positive and negative votes using Ajax.
Go to release and just download and install simplevote.zip file in WP plugin section. After that you just have to activate it.
Usage is as simple as it gets. You have only two options to choose from in the "Was this article helpful?" section. Right below the post.
This plugin does not use cookies. It checks whether you are logged in or not. If not, it will check your IP address. You can only vote once.
It uses AJAX. When you choose what to vote for, it disables voting buttons, but shows what you voted for. Other fields are automatically changed according to data from database and your input.
If you want to test how it works with multiple votes, you'll need to use your WP database. You just need to go to your wp_usermeta table and find the meta_key called voted_posts. Just delete it and you can do it again.
In case you want to clear all votes for any post, just go to wp_postmeta table and delete any meta_key that contains positive or negative. That's where all the votes count.
There are two fields "Thank you for your feedback.". One counts positive, other negative votes as primary. There was no explanation in the task, so it was left like this.
Everything is tested on WordPress 6.4.2.
All pointer actions are disabled after voting. Styling is as close as it can be. It is also mobile friendly. There are only 3 files, PHP, JS and CSS. All functions inside files are commented.
