Question

我有一个仍然无法解决的问题。在一个视图中，我试图从表中获取一些信息，从这些信息中，我需要保存新数据，并更新同一表上的其他一些数据，但是，当我单击“保存”时，什么也没发生。

我一直在这里寻找和通过互联网，发现类似的东西，但没有任何帮助。

我有这样的看法：

<div class="form-group">
    {!! csrf_field() !!}        

    @if(isset($impressora))       

        <div class="form-row">
            <div class="form-group col-md-4">
                <label for="setor">Setor*:</label>
                <input class="form-control" placeholder="Digite o setor..." required="required" name="setor" type="text" value="{{ $impressora->setor }}" id="setor">
            </div>
            <div class="form-group col-md-4">

我有一个这样的模型：

<?php

namespace SouzaCambos;

use Illuminate\Database\Eloquent\Model;

class TiPrinter extends Model
{
   protected $table = 'titoner_troca';

   protected $primaryKey = 'idtroca';

   public $timestamps = false;

   public $increment = false;    
}

在我的控制器中，我有这个：

public function printerInsert(Request $request){

    $PrinterTable = TiPrinter::all();

    //dd($PrinterTable);

    if ($PrinterTable->idtroca != null) {
        $oldsheet = TiPrinter::latest('folhas')
            ->where('marca', $request->marca)
            ->where('modelo', $request->modelo)
            ->where('toner', $request->toner)
            ->where('marca_toner', $request->tonerMarca)
            ->first();

        $pageCount = TiPrinter::latest('folhasnew')
            ->where('marca', $request->marca)
            ->where('modelo', $request->modelo)
            ->where('toner', $request->toner)
            ->where('marca_toner', $request->tonerMarca)
            ->first();
    }   

    $TiPrinter = new TiPrinter;
    $TiPrinter->setor = $request->setor;
    $TiPrinter->marca = $request->marca;
    $TiPrinter->modelo = $request->modelo;
    $TiPrinter->toner = $request->toner;
    $TiPrinter->marca_toner = $request->tonerMarca;
    $TiPrinter->folhas = $request->folhas;

    if (is_null($pageCount)) {
        $pageCount->folhasnew = 0;
    } elseif ($pageCount->folhasnew >= 0) {            
        $pageCount->folhasnew = $request->folhas - $oldsheet->folhas;
        $TiPrinter->folhasnew = 0;
        //$TiPrinter->folhasnew = $request->folhas - $oldsheet->folhas;
    }      

    //Decremento toner
    $printerSub = TiToner::where('modelo', $request->toner)
        ->where('marca', $request->tonerMarca)
        ->first();

    $printerSub->quantidade = $printerSub->quantidade - $request->quantidade;
    $printerSub->data = $request->dataTroca;

    //Save na tabela toner
    if ($pageCount != null) {
        $pageCount->save();
    }
    $TiPrinter->save();
    $printerSub->save();        

    return redirect()->to('portal-cambos/ti/impressoras/TiImpressorasToner');
}

此外，我在dd（$ PrinterTable）中什么也没得到；一行，我已经在寻找这段代码很多次了，没有发现与我以前编写的其他代码有误或不同。

有人可以帮助我吗？也许有人会看到我没看到的东西。

预先感谢所有，如果有关于此事的帖子，我想念它，请告诉我。

Answer 1

首先，您在视图中没有站点提供的开始表单标签，不确定是否忘记复制它。

<form method="post" action="{{ action('TestController@test') }}">

此表单内的“提交”按钮将基本上调用TestController中的测试方法，当然您需要根据需要对其进行修改。

第二，“表单”中有很多字段，但是模型中没有任何可填充数组，出于安全原因，您需要将每个字段（列）添加到可填充数组中，请执行以下操作：

class TiPrinter extends Model
{
   protected $table = 'titoner_troca';

   protected $fillable = ['value1', 'value2']; // add every fillable name into this array
}

您需要添加所有可填充元素，例如，如果我有一个表单，并且仅将value1和value2保存或修改，上面的方法就可以了。

第三，您应该能够将TiPrinter保存在存储方法中，如下所示：

public function store(Request $request) {
    $tiprinter = TiPrinter::create($request->all());

    if($tiprinter) {
        // success redirect to somewhere....
    }

    // error do something*
}

只需尝试以下步骤，如果仍然失败，请提供更多信息。
