[英]how to insert into multiple table using eloquent or DB facade in laravel from a single form
[英]How to insert data into multiple table in laravel from single Controller?
[我是 Laravel 的新手]
我正在使用 Laravel 5.5
我有ProductController和模型Product还有两个表products和pcategories 。 我想从ProductController将数据插入到pcategories表中。 如何正确地做到这一点? 我使用过DB::table('pcategories')->
在此处输入代码insert($data);
但它没有插入created_at
和updated_at
值。
另一个问题:我可以将多个模型调用到一个控制器中吗?
这是我的控制器
<?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');
}
/**
* Display the specified resource.
*
* @param int $id
* @return \Illuminate\Http\Response
*/
public function show($id) {
$product = Product::find($id);
return view('product.show')->with('product', $product);
}
/**
* Show the form for editing the specified resource.
*

*/
public function edit($id) {
$data['product'] = Product::find($id);
$data['categorieslist'] = Product::table('pcategories')->get();
return view('product.edit')->with($data);
}
/**
* Update the specified resource in storage.
*
* @param \Illuminate\Http\Request $request
* @param int $id
* @return \Illuminate\Http\Response
*/
public function update(Request $request, $id) {
$this->validate($request, [
'producttitle' => 'required',
'price' => 'required',
'photo' => 'image|mimes:jpeg,png,jpg,gif,svg',
]);
$product = Product::find($id);
$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/all')->with('success', 'Successfully Updated');
}
/**
* Remove the specified resource from storage.
*
* @param int $id
* @return \Illuminate\Http\Response
*/
public function destroy($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', $id)->delete();
return redirect('product/category/')->with('success', 'Successfully Deleted');
}
}
使用Eloquent Model
而不是Query Builder
。 字段created_at
, updated_at
是“一部分” Eloquent
。 您可以使用Eloquent
或manually
插入这些字段。
如果你想使用Eloquent
,那么制作两个模型Product
和PCategory
。 然后插入您的模型。
PCategory::create($data);
并且您需要在模型类上mass assigned
您的字段。如果您不想批量分配您的字段,请这样做-
$pcategory = new PCategory();
//$pcategory->column1 = $data['column1'] or $data->column1;
$pcategory->save();
要了解更多信息,请遵循此官方文档。
对于你的第二部分,是的,你可以。
首先,与您的模型建立适当的关系(一对多等)。其次,您可以使用 DB::transact 将数据插入到 DB 中的多个表中。 它有它自己的优点,而不是仅仅在表格中插入Fk来填充数据。 有关更多信息,您可以在谷歌搜索。
