Yii2: make checkbox to be checked
in a view which uses ActiveForm., Explore Collectives , Collectives ,I guess this checkbox will be checked only if $model->order property take true value and if it has false (0 or null or false etc) value — field will be unchecked.
if your are setting an external value in checkbox.
order = "02256"; ?> field($model, "order")->checkbox(['value' => "02256"]); ?> Answer by Paxton Grant
Thanks! Now I see that I mistakenly used ActiveForm instead of Html helper to generate checkbox. For the sake of simplicity, I omitted some details in my question. One of them was that the checkbox was related not to a property of the model but to a property of an associated model. For this reason it is better to use Html helper than ActiveForm.,Refer the API docs. The active field checkbox will generate the «checked» tag attribute according to the model attribute value. So you simply set the default value of the model attribute, to true before you render your view.,So, how I can generate html code for a checkbox with attribute «checked»?,I feel myself a little crazy, but I can not manage to make a checkbox to be checked. I’d like to generate an html code like this
I feel myself a little crazy, but I can not manage to make a checkbox to be checked. I’d like to generate an html code like this
echo $form->field($model, 'order')->checkBox(['label' => . 'uncheck' => null, 'checked' => true]); echo $form->field($model, 'order')->checkBox(['label' => . 'uncheck' => null, 'checked' => 'checked']); Strangely enough, if I substitute «checked» with «selected»
echo $form->field($model, 'order')->checkBox(['label' => . 'uncheck' => null, 'selected' => true]); then generated html code contains attribute «selected»:

I expect to see the checkbox checked.,The checked option is ignored.,but to fix this issue we could set checked option only if it does not exist already here: ,this must be checked by default render but not working.
field($model, 'categories[]', ['options' => ['class' => 'xform-group']])->checkbox([ 'uncheck' => null, 'class' => 'chk', 'id' => 'model-category_id_' . $category->id, 'label' => $category->name, 'labelOptions' => ['class' => 'chk full-width'], 'template' => '', 'value' => $category->id, 'checked' => true, ]);?>Answer by Cillian Brewer
null: Checkbox is indeterminate.,0: Checkbox is unchecked.,1: Checkbox is checked.,You can set the plugin to allow three states or the default two states for the checkbox.
Generally, you may also want to set a default version globally for all Krajee Extensions (instead of setting it for each widget or extension separately). In order to do this, you can setup the bsVersion property within Yii 2 application params (i.e. Yii::$app->params[‘bsVersion’] ). To set this up, add this section of code to your application params configuration file (e.g. config/params.php ):
