php - livewire 内联表编辑表单在隐藏时停止向服务器提交任何请求，并且仅在单击编辑时显示
问题描述
我正在开发 Laravel livewire 中的内联组件表编辑功能，当表单显示为常规表行时，表单可以正常工作，但是当我尝试制作它时，用户在单击编辑时获取编辑行，当表单停止提交请求时点击提交。
当我拉起网络 chrome 工具时，它显示单击提交时没有发送请求。
这是组件的刀片

这是它的控制器：
<?php
namespace App\Http\Livewire;
use App\Models\Product;
use Illuminate\Support\Facades\DB;
use Livewire\Component;
class ProductsTable extends Component {
public $name;
public $quantity;
public $price;
public $editname;
public $editquantity;
public $editprice;
public $editedRow = null;
public function formSubmit() {
$product = new Product;
$product->name = $this->name;
$product->quantity = $this->quantity;
$product->price = $this->price;
$product->save();
$this->empty();
}
public function empty() {
$this->name = '';
$this->quantity = '';
$this->price = '';
}
public function editRow($id) {
$product = Product::findorfail($id);
$this->editedRow = $id;
$this->editname = $product->name;
$this->editquantity = $product->quantity;
$this->editprice = $product->price;
}
public function editSubmit($id) {
$product = Product::findorfail($id);
$product->name = $this->name;
$product->quantity = $this->quantity;
$product->price = $this->price;
$product->save();
$this->empty();
}
public function render() {
return view('livewire.products-table', ["products" => DB::table('products')->orderBy('name', 'desc')->paginate(9),]);
}
}
正如您在此处看到的，当我单击提交时没有发送请求：https

如果您需要更多信息，请询问我会定期检查这篇文章
谢谢您的时间。编辑：我已经解决了这个问题，我所做的是我放弃了表单方式，只是将输入与组件控制器中的变量与 wire:model 链接起来，尽管我不知道它有多安全，因为我没有使用 csrf。
解决方案
您忘记了编辑表单上的@csrf。
并继续使用模型产品，确保您尝试填写的字段是可填写的，它不会阻止您创建，但它可以用于编辑！
