How to publish content based on the country under WordPress

Unusually, I started working on the configuration of Quelbazar blog today. Program: a solution to customize some content of the blog based on the country of origin of the visitor. Specifically, I wanted to include country-specific ads. Because it doesn't help to offer Swiss ads to a french visitor, for example.

The method is quite simple, because others thought before us: there is a wordpress plugin that does it right: Custom Content By Country.

This plugin works through "shortcodes", so I let you go see the syntax in the documentation of the plugin. For the simple reason that I don't know how to insert a shortcode into the article unless it is interpreted…

The plugin works without other articles, but my goal was to use it in a widget. Article Using shortcodes everywhere gives us the solution: in the file functions.php (the one in wp-includes), add:

add_filter ('widget_text', 'shortcode_unautop');

add_filter ('widget_text', 'do_shortcode');
