laravel 5.4 select2 多项编辑
laravel 5.4 select2 multiple edit
我不知道如何填充我的 select2 表单的编辑功能。这是我的尝试。控制器:
public function edit($id)
{
$company = Company::find($id);
$categories = MainCategory::all();
$categories2 = array();
foreach ($categories as $category) {
$categories2[$category->main_cat_id] = $category->main_cat_name;
}
return view('company/edit_company')->with('company', $company)->with('categories', $categories2);
}
这是我的观点:
<select class="form-control select2-multi" name="company_main_cat[]" multiple="multiple" style="width: 50%" data-placeholder="select main category">
<option value='{{$category->main_cat_id}}'>{{$category->main_cat_name}}</option>
</select>
这是我的 JS:
<script type="text/javascript">
$('.select2-multi').select2();
$('.select2-multi').select2().val({!! json_encode($company->maincategories()->allRelatedIds()) !!}).trigger('change');
</script>
如果您将类别数据正确地显示在您的视图中;这似乎是代码中的一个数组。您可以在 select 元素中 foreach 它们。
<select class="form-control select2-multi" name="company_main_cat[]" multiple="multiple" style="width: 50%" data-placeholder="select main category">
@foreach($category as $category_single)
<option value='{{$category_single->main_cat_id}}'>{{$category_single->main_cat_name}}</option>
@endforeach
</select>
