How to make checkbox check by default in yii while using single form for create and update

formsyii

I am using single form for creating and updating a form.I need checkbox checked by default in the following form

<div class="row" style='float:left;;margin-left:5px'>
        <?php echo '<span for="label" style="margin-bottom:5px;font-size: 0.9em;font-weight: bold;">Label</span><br />'; ?>
        <?php echo $form->checkBox($model,'label_name',array('value'=>1,'uncheckValue'=>0,'checked'=>'checked','style'=>'margin-top:7px;')); ?>
        <?php echo $form->error($model,'label_name'); ?>
    </div>

i am using above code to achieve the same purpose i am not getting the result as expected. While updating the form it shows checked even though it was unchecked

It works on my end:

<?= $form->field($model, 'some_field')->textInput(['readonly' => true, 'value' => $model->isNewRecord ? 'Your Value' : $model->some_field]) ?>

Javascript – Preventing double-click bug with checkbox + label combination

Finally got one very ugly hack that worked for all the browsers, hopefully this will help anyone else who comes across the problem:

Disable selection with css because doing it in JS is simply too inefficient:

.form_class input[type=checkbox] + label{
    -webkit-user-select:none;
    -khtml-user-select:none;
    -moz-user-select:none;
    -o-user-select:none;
    user-select:none;
}

Prevent ALL clicking in JS, and manually do what clicking should do:

jQuery(document).on('click', '.form_class input:checkbox+label', function(event){
    // Assuming label comes after checkbox
    $(this).prev('input').prop("checked", function(i, val){
        return !val;
    });
    event.preventDefault();
})
