我可以将转发器小部件设置为在表单打开时自动加载吗？

它具有最大项目属性，它可以自动加载到最大项目数

所以用户不需要点击提示按钮

重新更新

这是我的 fields.yaml

fields:
nowarta:
    label: 'No. Warta'
    oc.commentPosition: ''
    span: auto
    placeholder: 'format penulisan ''No. 34 Tahun XIX'''
    type: text
tanggal:
    label: Tanggal
    oc.commentPosition: ''
    mode: date
    format: 'd - F - Y'
    span: right
    type: datepicker
    ignoreTimezone: false
renungan:
    label: 'Renungan Mingguan'
    oc.commentPosition: ''
    span: full
    type: section
renungan[judul]:
    label: 'Judul Renungan'
    oc.commentPosition: ''
    span: storm
    type: text
    cssClass: 'col-sm-6 col-sm-push-0'
renungan[bahanbaca]:
    label: 'Bahan Bacaan'
    oc.commentPosition: ''
    span: storm
    type: text
    cssClass: col-sm-6
renungan[isi]:
    label: Renungan
    oc.commentPosition: ''
    span: storm
    cssClass: 'col-sm-12 col-sm-push-0'
    type: richeditor
    size: huge
tabs:
fields:
    temakebum:
        label: 'Kebaktian Umum'
        oc.commentPosition: ''
        span: full
        type: section
        tab: 'Kebaktian Umum & Komisi'
    temakebum[tema]:
        tab: 'Kebaktian Umum & Komisi'
        label: Tema
        oc.commentPosition: ''
        span: storm
        cssClass: col-sm-11
        type: text
    temakebum[bacaan]:
        label: 'Bahan Bacaan'
        oc.commentPosition: ''
        span: storm
        cssClass: col-sm-6
        type: text
        tab: 'Kebaktian Umum & Komisi'
    temakebum[pujian]:
        label: Pujian
        oc.commentPosition: ''
        span: storm
        cssClass: col-sm-6
        type: text
        tab: 'Kebaktian Umum & Komisi'
    kebum:
        label: ''
        oc.commentPosition: ''
        prompt: 'Tambah Data'
        maxItems: '3'
        span: full
        type: repeater
        tab: 'Kebaktian Umum & Komisi'
        form:
            fields:
                jeniskeb:
                    label: 'Jenis Kebaktian'
                    oc.commentPosition: ''
                    span: storm
                    cssClass: col-sm-4
                    type: dropdown
                    options: jenisKeb
                khotbah:
                    label: Pengkhotbah
                    oc.commentPosition: ''
                    span: storm
                    cssClass: col-sm-4
                    placeholder: ''
                    type: text

dd($form->fields)

array:6 [▼
  "nowarta" => array:5 [▶]
  "tanggal" => array:7 [▶]
  "renungan" => array:4 [▶]
  "renungan[judul]" => array:5 [▶]
  "renungan[bahanbaca]" => array:5 [▶]
  "renungan[isi]" => array:6 [▶]
]

这就是我在控制器中所做的，如你所愿..

class WartaRutin extends Controller
{
    public $implement = ['Backend\Behaviors\ListController','Backend\Behaviors\FormController','Backend\Behaviors\ReorderController'    ];
    
    public $listConfig = 'config_list.yaml';
    public $formConfig = 'config_form.yaml';
    public $reorderConfig = 'config_reorder.yaml';

    public function __construct()
    {
        parent::__construct();
        BackendMenu::setContext('Mismaiti.MyWarta', 'main-menu-item', 'side-menu-rutin');
    }

    public function formExtendFieldsBefore($form) {    
    // we are checking we are creating record or updating
    // or even we can use $form->context here but I used $model->id
    // if $form->context == 'update'
    // if $form->context == 'create'
        if(is_null($form->model->id)) {
            // create time
            $iteration = $form->fields['kebum']['maxItems'];

            if(is_numeric($iteration) && $iteration > 0) {
                $emptyFields = [];
                while($iteration > 0) {                        
                    $emptyFields[] = ['jeniskeb' => ''];
                    $iteration--;
                }
                $form->model->kebum = $emptyFields;
            }

        }
        
    }
}

当我尝试执行时它返回一个错误——我已将所有 repeater_data 替换为 kebum

C:\xampp\htdocs\mywarta\plugins\mismaiti\mywarta\controllers\WartaRutin.php 第 30 行的“未定义索引：kebum”

我在这里错过了什么..？

嗯，我们可以使用one trick，因为你可能只需要这个，create time或者你可以扩展它update time as well，

我使用了字段repeater_data，您可以将其替换为您的字段field

字段.yaml

fields:

    ... other fields ...

    repeater_data:
        label: Repeater
        oc.commentPosition: ''
        prompt: 'Add new item'
        maxItems: '5'
        span: auto
        type: repeater
        form:
            fields:
                title:
                    label: Text
                    oc.commentPosition: ''
                    span: auto
                    type: text
                category:
                    label: Dropdown
                    oc.commentPosition: ''
                    options:
                        1: 'Item 1'
                        2: 'Item 2'
                    span: auto
                    type: dropdown

控制器

在你里面controller你需要添加这个method and code

public function formExtendFieldsBefore($form) {

    // we are checking we are creating record or updating
    // or even we can use $form->context here but I used $model->id
    // if $form->context == 'update'
    // if $form->context == 'create'
    if(is_null($form->model->id)) {

        // create time **logic**
        $iteration = $form->fields['repeater_data']['maxItems'];
        if(is_numeric($iteration) && $iteration > 0) {
            $emptyFields = [];
            while($iteration > 0) {

                // here you need to provide at least one field 
                // which you used in repeater I used `title`
                // and let it be empty or may be some default value 
                $emptyFields[] = ['title' => ''];
                $iteration--;
            }
            // dummy fields assignment to current form model
            $form->model->repeater_data = $emptyFields;
        }
        // **logic**

    }
    else {

        // if you need to adjust data in update time
        // you need to find difference and then need to add
        // additional dummy data as we are adding above
    }
}

有2个场景 create time和update time

创建时间

当用户创建记录时，我们将添加dummy fields以便转发器将按原样显示它们，already there并且使用maxItems propertythat完成field so its fully dynamic，现在用户不需要按下该按钮。

更新时间（假设 maxItems=5）

现在2nd scenario我们有其他条件，如果你希望你可以添加一些逻辑并在那里做你的事情，假设用户一次只能添加 2 条记录，所以下次我们需要添加3 dummy fields （2 个填充 + 3 个虚拟 = 总共 5 个作为 maxItem）所以你可以calculate there和add it from else part。

希望对你有帮助，如果有什么困难请留言。
