NOTE v2 is now an extension of the CF7 Smart Grid-layout plugin. You need to install it to use this plugin. Why is this? You can read this thread, and this post.
This plugin allows multilingual contact form 7 management using the polylang plugin. As of version 2.0 of this plugin, it is now developed as an extension of the CF7 Smart Grid-layout plugin. All 3 plugins, Polylang, CF7 Smart Grid-layout and Contact Form 7 need to be installed prior to installing this plugin. Works with multisite installations too.

  • Now you can use a single CF7 form shortcode for all your translations.
  • WARNING: ensure you follow the installation instructions along with the PolyLang settings adjustments.

Make your CF7 Form more portable

this plugin introduces form keys (which you can modify in the CF7 admin table). Keys are unique for each form, allowing you identify a form my its key rather than an ID. Why is this priceless? IDs changes from one server to the next because they are the custom post ID attributed by the WordPress installation, and therefore you develop your form in a local machine only to find out that the IDs are different when you move your form to your production server. To overcome this problem, we suggest you use a form key along with this plugin’s contact form shortcode, [cf7-form key="contact-us"]. Don’t worry your old contact form 7 shortcodes will still work too, behind the scenes we simply map the key to the ID and call the regular contact form 7 shortcode.

Similarly you can use any translated form shortcode, and the plugin will make sure the right language is loaded.

Please follow the Installation instructions carefully, especially the part about saving your Polylang settings after you have activated this plugin.
