Yii2: How to show checked values in CheckboxList

问题

I want to show checked values in my checkboxlist in Yii 2.0. Following is my code:

Main Array:

<?php
$featureArr = array(
    'Change Requester' => 'Change Requester',
    'Clone Request' => 'Clone Request',
    'Suspend Request' => 'Suspend Request',
    'In-Process Requests Open in Edit Mode' => 'In-Process Requests Open in Edit Mode',
    'Allow On-the-Fly Notifications' => 'Allow On-the-Fly Notifications',
    'Additional Comments Field' => 'Additional Comments Field',
    'Do Not Validate Draft Requests' => 'Do Not Validate Draft Requests',
    '(Web-Only) Allow File Attachments' => '(Web-Only) Allow File Attachments',
);

Getting data from table to display checked items:

$formFeatureModel = FormFeatureForm::find()->where("form_id=" . $model->id)->all();

$checkedFeatureArr = array();
foreach ($formFeatureModel as $data) {
    $checkedFeatureArr[$data->feature] = $data->feature;
}
?>

Checkbox field

<?= $form->field(new FormFeatureForm, 'feature')->checkboxList($featureArr, ['class' => 'featureCls']) ?>

I am getting checked item in $checkedFeatureArr from database. Now I just want to show checked items. So, Where should I pass $checkedFeatureArr array? Getting stuck in this.

Any help would be appreciated.

回答1:

When using it with model, you should fill feature model property with selected values instead.

$model->feature = $checkedFeatureArr;

Then it will be checked automatically.

Additional tips:

• It's better avoid concatenation in SQL, replace ->where("form_id=" . $model->id) with ->where(['form_id' => $model->id]).

• It's better create ActiveForm before rendering ActiveField.
