[我是Laravel的新人]
我正在使用Laravel 5.5
我有 ProductController 和型号产品我还有两个表产品和 pcategories 。我想从 ProductController 将数据插入 pcategories 表中。怎么做得好？我在DB::table('pcategories')->使用insert($data);输入代码created_at，但未插入updated_at和<?php
namespace App\Http\Controllers;
use Illuminate\Support\Facades\DB;
use Illuminate\Http\Request;
use App\Product;
use Image;
class ProductController extends Controller {
/**
* Display a listing of the resource.
*
* @return \Illuminate\Http\Response
*/
public function index() {
$product->categorieslist = Product::table('pcategories')->get();
return view('product.add')->with($data);
}
/**
* Show the form for creating a new resource.
*
* @return \Illuminate\Http\Response
*/
public function create() {
$product->categorieslist = Product::table('pcategories')->get();
return view('product.add')->with($data);
}
public function all() {
$product->products = Product::table('products')->get();
return view('product.all', $data);
}
/**
* Store a newly created resource in storage.
*
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
*/
public function store(Request $request) {
$this->validate($request, [
'producttitle' => 'required',
'price' => 'required',
'photo' => 'image|mimes:jpeg,png,jpg,gif,svg',
]);
$product = new Product;
$image = $request->file('photo');
if ($request->file('photo')) {
$product->photo = time() . '.' . $image->getClientOriginalExtension();
$imagePath = public_path('/images/product');
$img = Image::make($image->getRealPath());
$img->resize(250, 250, function ($constraint) {
$constraint->aspectRatio();
})->save($imagePath . '/' . $product->photo);
}
$product->title = $request->input('producttitle');
$product->description = $request->input('description');
$product->category = $request->input('category');
$product->price = $request->input('price');
$product->saleprice = $request->input('saleprice');
$product->weight = $request->input('weight');
$product->dimension = $request->input('dimension');
$product->color = $request->input('color');
$product->save();
return redirect('/product/')->with('success', 'Successfully Added');
}
/**

public function show($id) {

public function edit($id) {

}
/**

public function update(Request $request, $id) {
$this->validate($request, [

$product->save();
return redirect('/product/all')->with('success', 'Successfully Updated');
}
/**

*/
public function destroy($id) {
Product::find($id)->delete();
return redirect('/product/all')->with('success', 'Successfully Deleted');
}
public function category() {
$data['categories'] = DB::table('pcategories')->get();
return view('product.category')->with($data);
}
public function storecategory(Request $request) {
$this->validate($request, [
'category' => 'required',
]);
$data = array();
$data['category'] = $request->input('category');
DB::table('pcategories')->insert($data);
return redirect('/product/category')->with('success', 'Successfully Added');
}
public function categorydestroy($id) {
DB::table('pcategories')->where('id', $id)->delete();
return redirect('product/category/')->with('success', 'Successfully Deleted');
}
}
值。
另一个问题：我可以将多个模型调用到控制器中吗？
这是我的控制器
foreach($page->links as $link){
$comments = $link->comments;
}
答案 0 :(得分：1)
使用Eloquent Model代替Query Builder。字段created_at，updated_at是Eloquent的“部分”。您可以使用Eloquent或插入manually这些字段。
如果您想使用Eloquent，请制作两个模型Product和PCategory。然后插入您的模型。
PCategory::create($data);
你需要在模型课上mass assigned你的领域。如果你不想大规模分配你的领域，那么这样做 -
$pcategory = new PCategory();
//$pcategory->column1 = $data['column1'] or $data->column1;
$pcategory->save();
要了解详情，请按照this官方文档
进行操作对于你的第二部分，是，你可以。

首先，与您的模型建立适当的关系（一对多，等等） 其次，可以使用DB :: transact将数据插入DB中的多个表中。它有其自身的优势，而不仅仅是在表中插入Fk来填充数据。有关更多信息，您可以在google中搜索。
