HI @tjoengnguyen, sorry I'm just seeing this email now. To install it, click the Download Gist link on the right. Upload the .php file to your /wp-content/plugins directory. Then browse to your Plugins list in your WordPress admin panel and activate the Simple Phone Validation for Restaurant Reservations plugins.

Nate,
For the translation with loco translator in wordpress.
Loco can't find the 2 messages , the Text Domain: rtbdomain is found but the messages use 'restaurant-reservations' , if i changed this to rtbdomain it works with the translate string.
Is that a good idea or will it fail further up the line when posting a booking ?
