Laravel 5.8说"array_map():期望参数2是一个数组，int给定". [英] Laravel 5.8 says "array_map(): Expected parameter 2 to be an array, int given"

问题描述

我无法处理此错误，在Laravel 5.8上显示"array_map():期望参数2为数组，为给定的整数"

I can't handle this error says "array_map(): Expected parameter 2 to be an array, int given" on Laravel 5.8

基本上，我一直像往常一样尝试创建新记录，但是今天遇到了一些新错误.哈哈

Basically, I'm trying to create a new record as I've always done, but today get some new error. LOL

这是我关于存储方法的控制器

This is my controller about store method

 public function store(Request $request)
    {
        $request->validate([
        'deadline' => 'required|date',
        'category' => 'required',
        'title' => 'required|max:255',
        'street_name' => 'required|max:255',
        'street_number' => 'required|numeric',
        'city' => 'required|max:255',
        'chief_town' => 'required|max:255',
        'zipcode' => 'required|numeric',
        'region' => 'required|max:255',
        'country' => 'required',
        'short_description' => 'required|max:255',
        'description' => 'required|max:255',
        'prize_description' => 'required|max:255',
        'prizegiving_description' => 'required|max:255',
        'brief' => 'required|max:255',
        'max_winner' => 'required|numeric',
      ]);

      Opportunity::create($request->all());
      return redirect('/opportunity');
    }

我的原始create.blade.php

my raw create.blade.php

<form method="post" action="/opportunity">
        <div class="form-group">
            @csrf
            <label for="title">title:</label>

        </div>
            <button type="submit" class="btn btn-primary">Create</button>
    </form>

我的数据库表

public function up()
    {
        Schema::create('opportunities', function (Blueprint $table) {
            $table->bigIncrements('id');
            $table->string('title');
            $table->date('deadline');
            $table->string('category')->default('Care', 'Dres', 'Food', 'Home', 'Host', 'Job', 'Talk');
            $table->string('street_name');
            $table->integer('street_number');
            $table->string('city');
            $table->string('chief_town');
            $table->integer('zipcode');
            $table->string('region');
            $table->string('country')->default('Italy');
            $table->text('short_description');
            $table->text('description');
            $table->text('prize_description');
            $table->text('prizegiving_description');
            $table->text('brief');
            $table->integer('max_winner');
            $table->timestamps();
        });
    }

我的机会.php

class Opportunity extends Model
{
    protected $fillable = [
    'company_id',
    'deadline',
    'category',
    'title',
    'street_name',
    'street_number',
    'city',
    'chief_town',
    'zipcode',
    'region',
    'country',
    'short_description',
    'description',
    'prize_description',
    'prizegiving_description',
    'brief',
    'max_winner',
     ];
}

感谢MS，让我知道您是否还需要进行其他调查

Let me know if you need anything else to investigate, thanks to MS

这是键入Log::info($request->all());的结果 在控制器中

This is the results of typing Log::info($request->all()); in the controller

推荐答案

在您的 商店 方法中， company_id >仍然不会被控制器归档.

In your store method, company_id isn't filed anyway by the controller.

但是在您的模型中它是可填充的

But in your model it is fillable

我也有同样的问题.试试这个，对我有用:

I also had the same problem. try this, its work for me:

$input = $request -> except(['_token']);  //remove csrf token insertion

$input['company_id'] = put here company id as your way;

$order = Opportunity::create($input);
