传递给 Illuminate\Database\Grammar::parameterize() 的参数 1 必须是数组类型，给定字符串，在 Laravel 中调用

Question

很好，我有一个原始属性，我正在创建一个属性，并且该属性具有用户通过复选框选择的特征，我想知道如何将在我的特征表中选择的复选框集与属性一起保存身份证

控制器

   
        $characteristics = new Characteristic;
        
        $characteristics->characteristic = $request->input('characteristic');
    
        $characteristics->save();
        

迁移属性

 public function up()
    {
        Schema::create('properties', function (Blueprint $table) {
            $table->increments('id');
            $table->string('name')->nullable;
            $table->string('price')->nullable;
            $table->text('description')->nullable;
            $table->unsignedBigInteger('property_type_id')->nullable();
            $table->unsignedBigInteger('offer_type_id')->nullable();
            $table->unsignedBigInteger('spaces_id')->nullable();
            $table->unsignedBigInteger('departaments_id')->nullable();
            $table->unsignedBigInteger('municipalities_id')->nullable();
            $table->unsignedBigInteger('details_id')->nullable();
            $table->unsignedBigInteger('characteristics_id')->nullable();
            $table->string('images')->nullable;
            $table->float('lat')->nullable;
            $table->float('lng')->nullable;
            $table->string('address')->nullable;
            
            $table->timestamps();
            
            $table->foreign('property_type_id')->references('id')->on('property_type')->onDelete('cascade');
            $table->foreign('offer_type_id')->references('id')->on('offer_type')->onDelete('cascade');
            $table->foreign('spaces_id')->references('id')->on('spaces')->onDelete('cascade');
            $table->foreign('departaments_id')->references('id')->on('departaments')->onDelete('cascade');
            $table->foreign('municipalities_id')->references('id')->on('municipalities')->onDelete('cascade');
            $table->foreign('details_id')->references('id')->on('details')->onDelete('cascade');
            $table->foreign('characteristics_id')->references('id')->on('characteristics')->onDelete('cascade');

        });
    }

迁移特征

 public function up()
    {
        Schema::create('characteristics', function (Blueprint $table) {
            $table->id();
            $table->unsignedBigInteger('property_id');
            $table->string('characteristic');
            $table->timestamps();
        });
    }

Answer 1

好像你的$request->input('characteristic'); 是一个数组而不是字符串。

你需要一个循环来解决这个问题。一种方法可以是：

$data = []

foreach ($request->input('characteristic') as $characteristic) {
   $data[] = [
      'characteristic' => $characteristic,
      'property_id' => '' // something
   ];
}

Characteristic::insert($data);

---

通过设置hasMany() 关系来使用->saveMany() 是一种更好的方式。

$characteristics = [];

foreach ($request->input('characteristic') as $characteristic) {
   $characteristics = new Characteristic([
        'characteristic' => $characteristic
   ]);
}

$property->characteristics()->saveMany($characteristics);

Answer 2

我能够按如下方式保存数据

$piso_id = $properti->id;
        
            foreach ($request->input('characteristic') as $characteristic) {
               
               $charc = new Characteristic;
               
               $charc->property_id = $piso_id;
               $charc->characteristic = $characteristic;
               $charc->save();
            }
