数组到字符串的转换 Laravel 上传多张图片

Question

我正在尝试保存我的属性的多个图像，一个属性可以有多个图像，但我收到此错误

如果你能在这里帮助我，我想知道它会产生什么我将控制器留在存储功能中

代码上传图片

public function store(Request $request)

    {
      /*--from this session you start to save the properties with all their attributes  --*/
      
        $properti = new Propertie;

        $detail = new Detail;

        $detail->antiquity = $request->antiquity;
        $detail->furnished = $request->furnished;
        $detail->floor = $request->floor;

        $detail->save();

        $properti->details_id = $detail->id;

        $properti->name = $request->name;
        $properti->price = $request->price;
        $properti->description = $request->description;


        $properti->departaments_id = $request->departaments;
        $properti->municipalities_id = $request->municipalities;

        $properti->property_type_id = $request->type_property;
        $properti->offer_type_id = $request->type;


        $properti->details_id = $detail->id;
        $properti->images = $request->images;
        $properti->lat = $request->lat;
        $properti->lng = $request->lng;
        $properti->address = $request->address;


        if (isset($request->property_id)) {
            $property_type = $request->property_id;
        } else {
            $property_type = null;
        }
        
         $images=array();
        if($files=$request->file('images')){
        foreach($files as $file){
            $name=$file->getClientOriginalName();
            $file->move('image',$name);
            $images[]=$name;
            }
        }

        $properti->save();


        $piso_id = $properti->id;
        $space = new Space;

        $space->property_id = $piso_id;
        $space->bedrooms = $request->bedrooms;
        $space->bathrooms = $request->bathrooms;
        $space->parking = $request->parking;
        $space->area = $request->area;


        $space->save();

        $properti->spaces_id = $space->id;


        foreach ($request->input('characteristic') as $characteristic) {

            $charc = new Characteristic;

            $charc->property_id = $piso_id;
            $charc->characteristic = $characteristic;
            $charc->save();
        }    

        Session::flash('message', 'Se ha registrado su propiedad De forma exitosa');

        return redirect()->action('PropertyController@index');
        // return view('properties.index',compact('properties'));
    }

迁移 - 属性

 public function up()
    {
        Schema::create('properties', function (Blueprint $table) {
            $table->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->unsignedBigInteger('images_id')->nullable();
            $table->decimal('lat', 8, 5)->nullable;
            $table->decimal('lng', 8, 5)->nullable;
            $table->string('address')->nullable;
            
            $table->timestamps();
            
            $table->foreign('property_type_id')->references('id')->on('property_type');
            $table->foreign('offer_type_id')->references('id')->on('offer_type');
            $table->foreign('spaces_id')->references('id')->on('spaces');
            $table->foreign('departaments_id')->references('id')->on('departaments');
            $table->foreign('municipalities_id')->references('id')->on('municipalities');
            $table->foreign('details_id')->references('id')->on('details');
            $table->foreign('images_id')->references('id')->on('images');
           //$table->foreign('characteristics_id')->references('id')->on('characteristics')->onDelete('cascade');

        });
    }

迁移图片

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

我的房产模型

  public function Images()
    {
        return $this->hasMany('App\Image', 'images_id');
    }

模型图像

class Image extends Model
{
    protected $fillable = ['name', 'property_id'];
    
   public function properties()
    {
     return $this->belongsTo('App\Properties');
    }
}

我不知道我的控制器是否有问题，但它在保存之前给了我错误

这是给images分配一个数组：

$properti->images = $request->images;

然后您正在调用 $properti->save()，它试图保存该数组，但它不能；它会尝试将其转换为字符串，但它不能。所以你可以评论/删除这一行。

如果你想通过关系保存这些，你可以尝试这样的事情：

$properti->save();

foreach($files as $file) {
    $name=$file->getClientOriginalName();
    $file->move('image',$name);
    
    // create a new Image and relate it to the property
    $properti->images()->create(['name' => $name]);
}
