There is a requirement that needs to be completed in the laravel-admin project:

After selecting a select option, it needs to be assigned to the select2 and select3 options simultaneously

laravel-admin select联动问题

I learned that laravel-admin itself has the ->loads() method, so I tried to use it, as follows:

$form->select('goods', __('商品名称'))->options(function(){
            $list = [];
            $goods = Good::where('state',1)->get();
            foreach ($goods as $k => $v) {
                $list[$v['id']] = $v['name'];
            }
            return $list;
        })->loads(['supplier_goods','purchaser_good'],['/api/getsuppliergoods','/api/getpurchasergoods']);
$form->multipleSelect('supplier_goods', __('供应商商品'));
$form->multipleSelect('purchaser_good', __('采购商商品'));

After actual operation, It was found that supplier_goods can be selected normally, but the purchaser_good option box can display the content normally, but the content cannot be selected, and no error was reported. [Recommended: laravel tutorial]

Change multipleSelect to select: $form->select('purchaser_good', __('Purchaser product ')); Run it again and find that it still cannot be selected, and the following error will be reported when clicking:

After some inspection, I finally found the problem, it turned out to be '/api/getpurchasergoods' There is a problem with the method written in the corresponding controller.

The official unified writing method is->get(['id', DB::raw('purchaser_id as text')])->toarray();

But since I originally wanted to get the purchaser ID directly, I changed it to: ->get(['purchaser_id', DB::raw('purchaser_id as text')])-&gt ;toarray();

This may result in the framework not being able to find the corresponding id, so further selection operations cannot be performed.
