推荐答案

如果要将HTML输出存储在数据库中(您不应该使用IMO)，则可以这样做:

If you want to store the HTML output in the database (you shouldn't IMO), you can do it like this:

<?php

namespace App\Http\Controllers;

use App\SomeModel;
use Illuminate\Http\Request;
use GrahamCampbell\Markdown\Facades\Markdown;

class SomeController extends Controller
{
    /**
     * Handle form submission of my markdown form.
     *
     * @return redirect
     */
    public function create(Request $request)
    {
        $markdownInput = $request->get('markdown_input');

        $model = new SomeModel();
        $model->html = Markdown::convertToHtml($markdownInput);

        if ($model->save()) {
            return redirect('/success');
        }
        else {
            die("Handle failed submission.");
        }
    }
}

但是，正如我说的那样，您不应该这样做，因为这将需要大量的存储 IF ，您的数据库中有很多记录.如果没有，那就不会受伤.

But as I said, you shouldn't because it will take a lot of storage IF you have a lot of records in your database. If not, it won't hurt.

相反，将原始markdown输入保存在数据库中，而不将其转换为HTML，并在视图中将输入转换为HTML:

Instead, save the raw markdown input in your database without converting it to HTML and convert the input to HTML in your views:

在config/app.php中，为Markdown外观添加别名:

In config/app.php add an alias to the Markdown facade:

'Markdown' => 'GrahamCampbell\Markdown\Facades\Markdown'

然后，您可以执行以下操作:

Then in your views you can do:

{{ Markdown::convertToHtml($rawMarkdownInputFromTheDatabase) }}
