Laravel Voyager - 使用自定义表单在前端上传图片

Question

我正在与航海者 (Laravel) 合作。我有一个带有图像字段的模型，这个模型是在后台创建的，我已经有了 CRUD。我想在前端创建一个表单，以便可以提交未登录的用户。但我不知道如何上传以遵循 voyager 在后台使用的相同规则（自动生成 CRUD）

有什么帮助吗？谢谢你

如果您愿意，可以使用 voyager 视图和控制器 首先，您可以创建一个扩展 VoyagerBaseController 的控制器 https://docs.laravelvoyager.com/customization/overriding-files

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use TCG\Voyager\Http\Controllers\VoyagerBaseController as BaseVoyagerBaseController;
use Illuminate\Support\Facades\DB;
use TCG\Voyager\Database\Schema\SchemaManager;
use TCG\Voyager\Events\BreadDataAdded;
use TCG\Voyager\Events\BreadDataDeleted;
use TCG\Voyager\Events\BreadDataUpdated;
use TCG\Voyager\Events\BreadImagesDeleted;
use TCG\Voyager\Facades\Voyager;
use TCG\Voyager\Http\Controllers\Traits\BreadRelationshipParser;
use App\Image;
use App\Document;
use App\Property;
use App\Demand;

class CustomVoyagerController extends BaseVoyagerBaseController
{
    public function index(Request $request)
    {
        // GET THE SLUG, ex. 'posts', 'pages', etc.
        $slug = $this->getSlug($request);

        // GET THE DataType based on the slug
        $dataType = Voyager::model('DataType')->where('slug', '=', $slug)->first();

        // Check permission
        $this->authorize('browse', app($dataType->model_name));

        $getter = $dataType->server_side ? 'paginate' : 'get';

        $search = (object) ['value' => $request->get('s'), 'key' => $request->get('key'), 'filter' => $request->get('filter')];
        $searchable = $dataType->server_side ? array_keys(SchemaManager::describeTable(app($dataType->model_name)->getTable())->toArray()) : '';
        $orderBy = $request->get('order_by');
        $sortOrder = $request->get('sort_order', null);

        // Next Get or Paginate the actual content from the MODEL that corresponds to the slug DataType
        if (strlen($dataType->model_name) != 0) {
            $relationships = $this->getRelationships($dataType);

            $model = app($dataType->model_name);
            $query = $model::select('*')->with($relationships);

            // If a column has a relationship associated with it, we do not want to show that field
            $this->removeRelationshipField($dataType, 'browse');

            if ($search->value && $search->key && $search->filter) {
                $search_filter = ($search->filter == 'equals') ? '=' : 'LIKE';
                $search_value = ($search->filter == 'equals') ? $search->value : '%'.$search->value.'%';
                $query->where($search->key, $search_filter, $search_value);
            }

            if ($orderBy && in_array($orderBy, $dataType->fields())) {
                $querySortOrder = (!empty($sortOrder)) ? $sortOrder : 'DESC';
                $dataTypeContent = call_user_func([
                    $query->orderBy($orderBy, $querySortOrder),
                    $getter,
                ]);
            } elseif ($model->timestamps) {
                $dataTypeContent = call_user_func([$query->latest($model::CREATED_AT), $getter]);
            } else {
                $dataTypeContent = call_user_func([$query->orderBy($model->getKeyName(), 'DESC'), $getter]);
            }

            // Replace relationships' keys for labels and create READ links if a slug is provided.
            $dataTypeContent = $this->resolveRelations($dataTypeContent, $dataType);
        } else {
            // If Model doesn't exist, get data from table name
            $dataTypeContent = call_user_func([DB::table($dataType->name), $getter]);
            $model = false;
        }

        // Check if BREAD is Translatable
        if (($isModelTranslatable = is_bread_translatable($model))) {
            $dataTypeContent->load('translations');
        }

        // Check if server side pagination is enabled
        $isServerSide = isset($dataType->server_side) && $dataType->server_side;

        $view = '**YOUR_CUSTOM_VIEW_HERE**';

        if (view()->exists("voyager::$slug.browse")) {
            $view = "voyager::$slug.browse";
        }

        return Voyager::view($view, compact(
            'dataType',
            'dataTypeContent',
            'isModelTranslatable',
            'search',
            'orderBy',
            'sortOrder',
            'searchable',
            'isServerSide'
        ));
    }
}

并创建从此处的 voyager 编辑添加刀片继承的自定义视图 \vendor\tcg\voyager\resources\views\bread

复制edit-add.blade.php， 根据您的喜好进行编辑， 更改控制器 $view = 'YOUR_CUSTOM_VIEW_HERE';与资源的真实路线。

现在你在前端使用了控制器和来自 laravel 的视图，记住从 laravel 布局中加载你需要的所有内容
