Here’s an example of a multilingual website (Welsh and English) I developed recently for the CULT Cymru training programme.
It’s all built on WordPress with a few custom things for this site, such as the design theme. Another example is that I developed a new plugin to show the testimonials widget (which is on the right in the screenshot above). This selects a testimonial randomly from the batch which are stored as a custom post type. This has to be done in the language that the visitor has chosen.
This is what the testimonials look like for editors on the back end:
The process was also an opportunity to move from an older domain name to the new cult.cymru name as well.
