Laravel 5.8 SQLSTATE[23000]：違反完整性約束：1048

Question

添加 TinyMCE 編輯器而不是我擁有的通用編輯器后，我收到 SQLSTATE[23000]：完整性約束違規錯誤。 在做了一些研究后，我發現我錯過了name標簽。 但是添加它並沒有什么不同。 我在下面添加了我的代碼。

Answer 1

您已將文本區域命名為“描述”

 <div class="card-body pad">
    <div class="mb-3">
        <textarea id="basic-conf" class="textarea" name="description" placeholder="Place some text here" style="width: 100%; height: 200px; font-size: 14px; line-height: 18px; border: 1px solid #dddddd; padding: 10px;"></textarea>
    </div>
</div>

您正在嘗試通過 $request object 的鍵“productDescription”獲取價值，這自然會返回 null。

嘗試

public function store(Request $request)
    {
        $this->validate($request, [
            'productName'=>'required',
            'slug'=>'required',
            'image'=>'required',
            'description'=>'required',
        ]);
        $product = new product();

        $product->product_name = $request->productName;
        if ($request->hasFile('image')) {
            $image = $request->file('image');
            $image_name = time() . $image->getClientOriginalName();
            $destinationPath = public_path('/uploads/products');
            $image->move($destinationPath, $image_name);
            $product->image = $image_name;
        }

        $product->slug = $request->slug;
        $product->description = $request->description;   //changed from productDescription to description
        $product->save();
        return redirect(route('product.index'));
    }
