这是我的密码。 我正在尝试访问bookname和bookauthor。 但变量是静态设置的。 我不想把这个改成公共的。 但我想访问这些值。 我怎么能做到呢？
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
class Book
{
private $bookName;
private $bookAuthor;
public function __construct($name, $author)
{
$this->bookName = $name;
$this->bookAuthor = $author;
}
public function getNameAndAuthor()
{
return $this->bookName . ' - ' . $this->bookAuthor;
}
}
class BookFactory
{
public static function create($name, $author)
{
return new Book($name, $author);
}
}
class FactoryController extends Controller
{
public function index()
{
$book1 = BookFactory::create('Laravel', 'Imrul');
$book2 = BookFactory::create('ReactJS', 'Hasan');
$book1->getNameAndAuthor();
$book2->getNameAndAuthor();
// dump($book1);
// dd($book1);
return view('home', compact(['book1', 'book2']));
}
}
home.blade.php
<h3>{{ $book1->bookName }}</h3>
<h3>{{ $book1->bookAuthor }}</h3>
我建议您创建一个模型:php artisan make:model book-a，wit-a将在模型之外创建您的迁移和控制器。
在迁移中:
public function up()
{
Schema::table('books', function (Blueprint $table) {
$table->increments('id');
$table->string('author');
$table->string('title');
});
}
在您的模型上:
class Book extends Model
{
protected $table = 'books';
protected $fillable = [
'author', 'title'
];
}
在控制器上:
public function create()
{
$book1 = Book::create([
'author' => 'Henry',
'title' => 'Smith',
]);
$book2 = Book::create([
'author' => 'Antony',
'title' => 'Gjj',
]);
return view('home', compact(['book1', 'book2']));
}
在你的刀刃上:
<h3>{{ $book1->title }}</h3>
<h3>{{ $book1->author }}</h3>
class Book
{
private $bookName;
private $bookAuthor;
public function __construct($name, $author)
{
$this->bookName = $name;
$this->bookAuthor = $author;
}
public function getNameAndAuthor()
{
return $this->bookName . ' - ' . $this->bookAuthor;
}
public function getBookNameAttribute()
{
return $this->bookName;
}
public function getBookAuthorAttribute()
{
return $this->bookAuthor;
}
}
现在blade中的代码应该可以工作了:
<h3>{{ $book1->bookName }}</h3>
<h3>{{ $book1->bookAuthor }}</h3>
