[5.5] add ability to show input value in validation error messages

[themsaid]

validator(['email' => 'Mohamed'], ['email' => 'email'])->validate();

With this PR, you can have the error message of the email rule as :actual_value is not a valid email, and the error output will become Mohamed is not a valid email.

@themsaid This can lead to XSS errors when showing errors using something like Sweetalert...

[themsaid]

It's not used by default in the framework, it's optional so you can use it if you want and apply xss protection on the form submission before handing it to the validator.

@themsaid finally it is fixed I have raised this bug earlier in 5.4 but I am unable to find it but will be good to see if you can send it to 5.4 as well as it is more of a patched.
Thanks for your continuous contribution to the laravel community.

I would call the place-holder :input.

[themsaid]

@taylorotwell renamed to :input

I suggested this on TWITTER 😃 !, is it available on 5.4?

[themsaid]

@leyluj nope, 5.5 only, 5.4 isn't maintained anymore. The upgrade is really easy you should do it :)

[leyluj]

Noted let me try.

Thanks

[leyluj]

Done, i have upgraded but :input is not working.

What might be the problem?

[themsaid]

@leyluj will be released on next patch.

you can use it if you want and apply xss protection on the form submission before handing it to the validator.

@themsaid Will this be made clear in the documentation?
