Displaying old input

- [Instructor] One the best things we can do … to improve the usability of our forms for everyone … is to display the old input in the form, … so that way our users don't have to retype in … what they already did when a form fails validation. … Laravel provides a blade directive for our us … to solve this problem. … This blade directive is called "old", … that retrieves the old input from the session to display. … We're going to add it to our form for editing the bookings. … Open up the file at resources, views, … bookings, fields.blade.php. … We can use it for text … and other similar fields pretty easily. … Scroll down to where our start date is displayed. … In this case, it's on line 40. … We're going to update this to use that old blade directive … before attempting to display the value from the model. … This means we'll update in our value property … for the HTML field, "one", old, parenthesis, … pass in the string "start" … and then a double question mark … to do a null coalesce operation. …
