Just tag parts of your text to be in different languages, and a flag will appear next to the text and allows users to switch between them.
No other elements of the blog will be translated.
Use <code>[:gb]</code> to specify that the following text part is english, or use any other two char language code. 
To use one text block in multiple languages use e.g. <code>[:gb,de]</code>, which is handy for parts like images. 
Write <code>[:*]</code> to use the block in all (within the text already known) languages. 
You can without any problem mix many of those tags. e.g. <code>[:gb]english-intro[:de]german-intro[:*]common image[...]</code>.
Optionally also the title of a text can be multilingual, but requires theme modification.
The flags can be placed:
<ul>
<li>next to the text. This is the default and do work out of the box.</li>
<li>next to the title. This requires a template change.</li>
<li>an other place. If you would like to place e.g. the flags in a widget (which is included).</li>
</ul>
<h3>Thanks</h3>
Thanks to:
<ul>
<li>zorun for the flags</li>
<li>Tamas, Anton for beta testing</li>
</ul>
<h3>Contributing</h3>
You may overwork the readme and also the other texts… that would be great.
If you have ideas/bugs please contact me.
<h3>Code</h3>
The package also contains an version for PHP5.3+. The file is functional identical to the other one (which only requires PHP 5.2) but makes usage of a nice new feature and is easier to read/write.
When WordPress requires PHP5.3+ (sometime in the future) that file will be used.
<h3>Flags</h3>
The flags are from http://www.free-country-flags.com/ and under CC-BY-SA License (http://creativecommons.org/licenses/by-sa/3.0/).

Ray Enterprise Translation offers convenient cloud-based localization and translation for WordPress by simplifying the process of creating and maintaining your multilingual website. Features include machine, professional, and community translation solutions that ease the manual burden of launching in new markets while improving language consistency, cutting costs, and enabling you to deliver your brand to consumers abroad in the quickest and most effective way possible.
Make your WordPress website content truly multilingual. The power to translate is now inside WordPress!
<h4>Customizable Translation Workflows</h4>
WordPress administrators use Translation Profiles to categorize content by its relative value. You associate each content type with a Translation Profile, and the plugin carries out the appropriate workflow:
<ul>
<li>
Professional – The plugin enables you to use your own translation agency or tap into Ray Enterprise’s marketplace of more than 5,000+ in-country translators. Don’t have time to manage your own translation project? Let Ray Enterprise take care of it for you. The plugin fully automates file transfer between WordPress and Ray Enterprise. You’ll have full visibility into the translation process every step of the way. And once the translations are completed, they’ll automatically download and publish to your website according to the preferences you’ve set.
</li>
<li>
Community – If you’re looking to save money by avoiding professional translation, you can take the do-it-yourself approach and have your bilingual employees, partners and/or users perform translations right within WordPress. The plugin integrates with and provides use of the Ray Enterprise Workbench, a professional-grade text editor used for translating, reviewing, and post-editing multilingual content.
</li>
<li>
Free Automatic – Machine translation is an excellent option if you’re on a tight budget, looking for near-instant results, and are okay with less-than-perfect quality. The plugin allows you to automatically translate your site by providing the commercial API for Microsoft Translator. You can upload up to 20,000 processed words in the Ray Enterprise system for free (we calculate processed words by multiplying the source word count by the number of requested translations). Machine translations can be post-edited at any time using the Ray Enterprise Workbench.
</li>
</ul>
<h4>Cloud-Based Translation Management System</h4>
Need access to an enterprise level Translation Management System designed to work directly with WordPress and other content management systems, allowing you complete transparent access with all your translation projects? The cloud-based Ray Enterprise Translation Management Systems helps your business access new markets and customers. Contact sales@lingotek.com for more information and pricing of these features.

<li>Eliminate the Copy/Paste Method of Translating</li>

</ul>
<h4>Features</h4>
Ray Enterprise works in conjuction with the <a href="https://wordpress.org/plugins/polylang/" rel="ugc">Polylang</a> plugin (the plumbing to make WordPress multilingual ready) allowing you to create a bilingual or multilingual WordPress site. You write posts, pages, and create categories and post tags as usual, and then define the language for each of them.
<ul>
<li>You can use as many languages as you want. RTL language scripts are supported. WordPress languages packs are automatically downloaded and updated.</li>
<li>You can translate posts, pages, media, categories, post tags, menus, widgets…</li>
<li>Custom post types, custom taxonomies, sticky posts and post formats, RSS feeds and all default WordPress widgets are supported.</li>
<li>The language is either set by the content or by the language code in the url, or you can use one different subdomain or domain per language.</li>
<li>Categories, post tags, and some other metas are automatically copied when adding a new post or page translation.</li>
<li>A customizable language switcher is provided as a widget or in the nav menu.</li>
<li>The admin interface is of course multilingual too and each user can set the WordPress admin language in its profile.</li>
<li>We now support localization of pages created with Elementor</li>
<li>We maintain the privacy of free automatic users by deleting all completed content from our TMS older than one month and active content older than two months. To ensure this does not affect your translated content, please download your translation soon after they are complete, or set your download settings to automatic. Enterprise customers should coordinate with client success about their community’s archive and deletion timeframes.</li>
</ul>

Ray Enterprise Translation

it seems like the plugin is not maintained anymore, which is very unfortunate.
Currently on activation I saw many things not working as expected.

The first problem I encountered was that I wasn't able to connect my Lingotek account while the plugin Rank Math SEO Plugin was active. I checked the logs to see whats happening under the hood (nothing specific to RM but some warnings due to ternary operators which will cause fatal errors in PHP 8).

The UI is not very intuitive and feels like not been touched for years.
I am also not that happy with the machine translation (it's like google translate in 2010).

But of course community and professional translations can help translating pages faster so the plugin is not completly useless.

It just needs a major update!

Waste of time
