How to create dynamic field in Yii2? - input

Question

I have one table where I am saving field name.
Now I want to use those fields in another model. So, How can I give name to that field?
e.g.
I have table named as Config with fields(id,key).
Data can be
1, Blog url
2, Site url
Now, I have 1 form where admin will add those value to database.
In Yii2 we create input field like
<?= $form->field($model, 'name')->textInput() ?>
But I want to create two textboxes with name blog url and site url.
So, How can I create it? What I have to write in place of name?

run this code on your command prompt
php composer.phar require --prefer-dist wbraganca/yii2-dynamicform "*"
after completion of above code.
add the following code in your form.
_form.php
<div class="panel panel-default">
<div class="panel-heading"><h4><i class="glyphicon glyphicon-envelope"></i> Addresses</h4></div>
<div class="panel-body">
<?php DynamicFormWidget::begin([
'widgetContainer' => 'dynamicform_wrapper', // required: only alphanumeric characters plus "_" [A-Za-z0-9_]
'widgetBody' => '.container-items', // required: css class selector
'widgetItem' => '.item', // required: css class
'limit' => 4, // the maximum times, an element can be cloned (default 999)
'min' => 1, // 0 or 1 (default 1)
'insertButton' => '.add-item', // css class
'deleteButton' => '.remove-item', // css class
'model' => $modelsAddress[0],
'formId' => 'dynamic-form',
'formFields' => [
'name',
],
]); ?>
<div class="container-items"><!-- widgetContainer -->
<?php foreach ($modelsAddress as $i => $modelAddress): ?>
<div class="item panel panel-default"><!-- widgetBody -->
<div class="panel-heading">
<h3 class="panel-title pull-left">Address</h3>
<div class="pull-right">
<button type="button" class="add-item btn btn-success btn-xs"><i class="glyphicon glyphicon-plus"></i></button>
<button type="button" class="remove-item btn btn-danger btn-xs"><i class="glyphicon glyphicon-minus"></i></button>
</div>
<div class="clearfix"></div>
</div>
<div class="panel-body">
<?php
// necessary for update action.
if (! $modelAddress->isNewRecord) {
echo Html::activeHiddenInput($modelAddress, "[{$i}]id");
}
?>
<?= $form->field($model, "[{$i}]name")->textInput(['maxlength' => true]) ?>
</div>
</div>
<?php endforeach; ?>
</div>
<?php DynamicFormWidget::end(); ?>
</div>
</div>
