This is a WordPress plugin (or more of a helper) that makes it easier to add OP calculator to your site without having to code anything.
You need an OP merchant account. Read more about it at OP Kauppiasportaali
This does not work as is. You need files from OP. Read more below.
This is not an official OP plugin.
Download this repository from github.com/kendafi/op-laskuri
Create a folder called op-laskuri (preferrably in you localhost wp-content/plugins folder)
and copy all files from the repository into it.
When you have an OP merchant account you should receive the ZIP file op-laskuri-asennus.zip from them.
Extract its content into the same op-laskuri folder as this README.md and op-laskuri.php files are in.
You should now have also the following files in the op-laskuri folder.
op-calc-widget.cssop-calc-widget.js
Set the settings for your calculator on OPs site
You should receive a script from there.
Copy that script into the file _op-script.js and rename the file op-script.js.
Upload the whole op-laskuri folder to your website server into the folder wp-content/plugins.
Log in to your WordPress admin and enable the OP Laskuri plugin.
Edit any page and add the shortcode [op-laskuri] into its content.
Save the page and see what it looks like.
The calculator should appear where you added the shortcode.
It should look something like the image below.
There is an option to get the webstore version HTML by adding an attribute to the shortcode: [op-laskuri shop=1]
