在Laravel中将默认值设置为Form：text（）

Question

Well, I am so lost in how to achieve this behavior. In my view I have this:

Form::text('time', Input::old('time'));

So, everything the form validator fails, the view is rendered again with the time input having the value that the user typed in the past... Everything is ok here.

What I want to do is to display a default in the time input from the beginning, something like this:

time:  [ now      ]

But if the user change the "now" word and the validator fails, I would like to the display the text submitted by the user instead of "now".

With Laravel 4, you don't have to explicitly tell it to load the old data, it will do this for you since you're using the Form::text macro.

So something like this will work for you:

Form::text('time', 'now');

That will set 'now' as the default, but if there is a value in Input::old('time') it will magically appear as the default.

You will need to ensure that you are redirecting back the form with input like this:

return Redirect::route('your.route')->withInput();

If you want to see the magic behind this, see the code here , then here , then finally here
