php - 检索复选框以查看是否已选中 laravel 5.2

Question

我的产品表单中有一个复选框，默认情况下该复选框未选中，并且设置为 0。如果选中该复选框，则会在数据库中插入 1 以使其知道产品将出现在首页。

我遇到的问题是，当我编辑产品时，即使数据库中有 1，该复选框也未被选中。我尝试了很多解决方案，但无法想出一个有效的解决方案。

这是我的功能:

public function addPostProduct(ProductRequest $request) {

        // Check if checkbox is checked or not for featured product
        $featured = Input::has('featured') ? true : false;

        // Create the product in DB
        $product = Product::create([
            'product_name' => $request->input('product_name'),
            'price' => $request->input('price'),
            'cat_id' => $request->input('cat_id'),
            'featured' => $featured
        ]);

        // Save the product into the Database.
        $product->save();

        // Flash a success message
        flash()->success('Success', 'Product created successfully!');

        // Redirect back to Show all products page.
        return redirect()->route('admin.product.show');
    }

这是我的添加表单(仅显示复选框):

 <div class="form-group">
    <label>Fetaured Product</label><br>
    <input type="checkbox" name="featured" value="1">
</div>

这是我的编辑表单(仅显示复选框):

 <div class="form-group">
      <label>Fetaured Product</label><br>
      <input type="checkbox" name="featured" value="1">
</div>

我的表结构:

Schema::create('products', function (Blueprint $table) {
            $table->increments('id');
            $table->string('product_name');
            $table->decimal('price', 10, 2);
            $table->integer('cat_id');
            $table->integer('featured')->default(0);
            $table->timestamps();
        });

我猜我也必须更新我的 updateProduct 函数。

 public function updateProduct($id, ProductEditRequest $request) {

        // Check if checkbox is checked or not for featured product
        $featured = Input::has('featured') ? true : false;

        $product = Product::where('id', '=', $id);

        // Update your cart
        $product->update(array(
            'product_name' => $request->input('product_name'),
            'price'   => $request->input('price'),
            'cat_id'    => $request->input('cat_id'),
            'featured'     => $featured
        ));


        // Find the Products ID from URL in route
        $product = Product::findOrFail($id);

        // Update the product with all the validation rules
        $product->update($request->all());

        // Flash a success message
        flash()->success('Success', 'Product updated successfully!');

        // Redirect back to Show all categories page.
        return redirect()->route('admin.product.show');
    }

我的编辑表单复选框如下:

<div class="form-group">
          <label>Fetaured Product</label><br>
          <input type="checkbox" name="featured" value="1" {{ $product->featured === 1 ? "checked=checked" : "" }}>
</div>
