关于Laravel-admin的基础用法总结和自定义model详解(2)

$grid->tools(function ($tools) {
 //关闭批量删除
 $tools->batch(function ($batch) {
  $batch->disableDelete();
 });
});

 $form->disableReset();

//默认展示$data['name']的值，新接收的值存储user表name字段
$form->text('user.name', '名称')->default($data['name']);

$form->image('user.logo', 'logo')
    #随机文件名
    ->uniqueName()
    #验证文件格式('mimes:doc,docx,xlsx');
    ->rules('mimes:png')
    #输入框下边的help提示语
    ->help($str);

$form->url('user.website', '官网')
    #默认填充url 传参
    ->default($url)
    #提示的url
    ->help('eg: http://www.aware.bi');

#下拉框展示$message提示语
$form->multipleSelect('project.tags1', $message)
    #下拉框数据
    ->options($tags['children']);

$types = array('0'=>'教育','1'=>'医疗');
$form->select('type', '类型')->options($types);

$users = User::all()->pluck('name', 'id')->toArray();

 'on' => ['value' => 1, 'text' => '上线', 'color' => 'success'],
 'off' => ['value' => 0, 'text' => '下线', 'color' => 'danger'],

$form->switch('status', '上/下线')->states($states);

$form->hidden('is_in');

$form->saving(function (Form $form) {
 #指定值为固定1
 $form->is_in = 1;
 #验证值是够有重复
 if($from->nick_name !== $form->model()->email && User::where('email',$form->email)->value('id')){
 #错误信息提示
 $error = new MessageBag(['title'=>'提示','message'=>'邮箱已存在!']);

 //自定义操作按钮
 $actions->append('<button type="button" class="btn btn-danger noShow"

 //当前数据的ID
});
