Yii, Looping form fields for Tabular Input - php

Question

I am using the Yii Framework 1.1.17, and have generated three models:
Question, AnswerOption and Response.
The relationships:
Table: Question (list of questions)
id
text
Table: AnswerOption (list of possible answers, associated with question)
id
question_id
text
Table: Response (question and selected answer collector)
id
question_id
answer_option_id
text
I am trying to create a form, and admittedly collect answers for all possible questions.
File: ResponseController
public function actionCreate()
{
// load all questions and with it the possible answer Options
$questions = Question::model()->findAll();
// get number of questions
$count = Question::Model()->count();
$model = array();
$i = 1;
while ($i <= $count) {
$model[] = Response::model();
$i++;
}
if (isset($_POST['Response'])) {
//
}
$this->render('create', array(
'model' => $model,
'questions' => $questions,
));
}
This is the area that I am having trouble with:
File: response/_form
<?php foreach($questions as $i=>$question): ?>
<?php echo CHtml::activehiddenField($question,"[$i]id"); ?> <?php echo $question['text']; ?>
<?php $options = CHtml::listData($question->answerOptions, 'id', 'text');?>
<?php echo CHtml::activeDropDownList(AnswerOption::model(), "[$i]text", $options, array('empty' => 'Select answer...')); ?>
<?php endforeach; ?>
I may have populated my questions and possible answers, but I need to validate and save the results in $model.
It seems like I cannot find a way to efficiently work this out. Can someone please guide me?

Answer 1

I managed to resolve my "loop" problem by:
File: response/_form
<?php $questions = Question::model()->findAll(); ?>
<?php foreach ($questions as $j=>$question): ?>
<div class="row">
<?php echo $form->labelEx($model["$j"], "[$j]question_id"); ?>
<?php echo $form->hiddenField($model["$j"], "[$j]question_id", array('value' => $question["id"])); ?>
<?php echo $question['text']; ?>
</div>
<div class="row">
<?php $options = CHtml::listData($question->answerOptions, 'id', 'text');?>
<?php echo $form->labelEx($model["$j"], "[$j]answer_option_id"); ?>
<?php echo $form->dropDownList($model["$j"], "[$j]answer_option_id", $options, array('empty' => 'Select answer...')); ?>
</div>
<?php endforeach; ?>
Hopefully, this would come in handy for someone, someday.
