Just one copy.

Suppose you return a model variable to the blade template engine.$postAndwebMiddleware (sessionYes. You can share oneform.blade.php,:

1. retain the old input items (using the old method), such as submitting a form, but the verification fails. After the page is submitted and refreshed, the data submitted last time is retained.

2. Old input items do not need to be retained

Write two copies or check whether the variable exists as needed

You do not need to write two copies,
Create a form. blade. php file, store the form options, and use isset to determine whether the output exists or not, or you can use Forms & HTML builder to make it easier.

If you write an input form yourself, write it as follows:

If laravel's Form is used, it is more concise:
InCreate. blade. phpMedium:

{!! Form: open (['url' => 'Article'])!} @ Include ('Article. _ Form', ['submitclick' => 'add an article ']) {! Form: close ()!!}

InEdit. blade. phpMedium

{!! Form: model ($ article, ['method' => 'patch ', 'url' => ['Article', $ article-> id])!} @ Include ('Article. _ Form', ['submitclick' => 'modify files']) {! Form: close ()!!}

A public form section is required:_ Form. blade. phpIs the form part.

I don't think we should use a framework to use it. laravel provides us with a lot of convenient operations. If we are using this framework, we should try to accept them.
