How To Change Form Fields Based On The Value Of Another Field In Yii

Yii 1.1 General Discussion
1

I’m new to Yii framework. I have a textfield that needs to be changed on radiobutton value.

i.e. if there are two radiobuttons single and Multi . This radiobuttonlist is another field ‘language’




    <div class="row" id="language">

            <?php echo $form->labelEx($model, 'language'); ?>

            <?php echo $form->radioButtonList($model, 'language',array('1' => 'Single',2 => 'Multi'));?>

            <?php echo $form->error($model, 'language'); ?>

        </div>

Now, based on the value,

if I select single (value =1),




    <div class="row">

                <?php echo $form->labelEx($model, 'audioUrl'); ?>

                <?php echo $form->textArea($model, 'audioUrl', array('rows' => 6, 'cols' => 50)); ?>

                <?php echo $form->error($model, 'audioUrl'); ?>

            </div>

    

            <div class="row">

                <?php echo $form->labelEx($model, 'selectList'); ?>

                <?php echo $form->dropDownList($model, 'selectList', array('' => ''), array('class' => 'multiselect')); ?>

                <?php echo $form->error($model, 'selectList'); ?>

            </div>

    

    

            <div class="row">

                <?php echo $form->labelEx($model, 'Name'); ?>

                <?php echo $form->textArea($model, 'Name', array('rows' => 6, 'cols' => 50)); ?>

                <?php echo $form->error($model, 'Name'); ?>

            </div>

In the above code, select list is a multi select.

if I select single (value =2),




    <div class="row">

                <?php echo $form->labelEx($model, 'audioUrl'); ?>

                <?php echo $form->textfield($model, 'audioUrl'); ?>

                <?php echo $form->error($model, 'audioUrl'); ?>

            </div>

    

            <div class="row">

                <?php echo $form->labelEx($model, 'selectList'); ?>

                <?php echo $form->textfield($model, 'selectList'); ?>

                <?php echo $form->error($model, 'selectList'); ?>

            </div>

    

    

            <div class="row">

                <?php echo $form->labelEx($model, 'Name'); ?>

                <?php echo $form->textfield($model, 'Name'); ?>

                <?php echo $form->error($model, 'Name'); ?>

            </div>

How can I change the form fields dynamically based on radiobutton selection.

LOL … “I’m new to Yii framework” seriously all your posts. just make me wonder for how long you gonna be new to yii

Well is it wrong to mention if I have a problem and not familiar to handle such situations.

Just need to call ajax as per the radio button selection and render the selectList on the form.

5

there is nothing wrong with that. I am just saying you just gotta stop saying you new to yii. also what i see most of your question are not related to yii most them are general web related

how to do this?

how to do that?

Hi alirz23, I understand what you tell. I will not repeat this again. As I’m using the radiobuttonlist to dynamically change the form fields, when I submit the form, the field values are post twice. Is it because I have repeated the fields with same id. Can you please tell me what should be done for this.

your going to need js

basically wrap each group in a new div and assign an id to each group.

hide both divs on initial view and have the js toggle divs bassed on selection.

if value = 1 show group 1

if value = 2 show group 2.

You will also need custom / conditional validation in your model to handle each variation.

You could also parse the value and count and see if the value is a single item or there are multiple and handle it that way instead of making them select single or multiple. it would be one less click for your users.
