如何从洋红色中的foreach循环中获取当前值


How to get current value from foreach loop in magento

我在magento中有一个模块,允许用户提出问题和回答问题。

该问题具有自动递增和唯一question_id。答案也有相同的配置。

但是,如果用户问 3 个问题,问题将按以下方式发布在前端......

<div>
        <?php if(!empty($questionData)): ?>
            <?php foreach ($questionData as $data): ?>
                <table>
                    <tr>
                        <td><h1>Question:</h1> <h3><b><?php echo $data['question']; ?></b></h3></td>
                    </tr>
                    <tr>
                        <td><h1>Asked by:</h1><h3><b><?php echo $data['username']; ?></b></h3></td>
                    </tr>
                    <tr>
                    </tr>
                    </table>
            </div>

由于foreach循环返回所有值,每个问题都被打印出来。

但是,如果用户输入第二个问题的答案,怎么可能只显示该特定问题的答案呢?

我已经尝试了下面的代码,但是,答案出现在每个问题中。

<?php $questionData = $this->getQuestionId($prod_id); ?>
<?php foreach ($questionData as $data):$questionid = $data['question_id']; endforeach; ?>
<?php $answerData = $this->getAnswer($prod_id,$questionid); ?>
<div id="answerswer_block">
                <?php if(!empty($answerData)): ?>
                    <?php foreach ($answerData as $answerPosted):?>
                        <h4>********************************************</h4>
                        <h3> Answer given by: <b><?php echo $answerPosted['username']; ?></b></h3>
                        <h3> Answer: <b><?php echo $answerPosted['answer']; ?></b></h3>
                    <?php endforeach; ?>
                <?php endif; ?>
            </div>  

 public function getAnswer($product_id,$question_id)
    {
        $answerModel = Mage::getModel('questionanswer/answer')->getCollection()
                ->addFieldToFilter('status',0)
                ->addFieldToFilter('product_id',$product_id)
                ->addFieldToFilter('question_id',$question_id);
        return $answerModel;
    }

这样在问题中添加答案foreach

<div>
        <?php if(!empty($questionData)): ?>
            <?php foreach ($questionData as $data): ?>
                <table>
                    <tr>
                        <td><h1>Question:</h1> <h3><b><?php echo $data['question']; ?></b></h3></td>
                    </tr>
                    <tr>
                        <td><h1>Asked by:</h1><h3><b><?php echo $data['username']; ?></b></h3></td>
                    </tr>
                    <tr>
                    </tr>
                    </table>
                    <?php 
$questionid = $data['question_id'];    
$answerData = $this->getAnswer($prod_id,$questionid); ?>
<div id="answerswer_block">
                <?php if(!empty($answerData)): ?>
                    <?php foreach ($answerData as $answerPosted):?>
                        <h4>********************************************</h4>
                        <h3> Answer given by: <b><?php echo $answerPosted['username']; ?></b></h3>
                        <h3> Answer: <b><?php echo $answerPosted['answer']; ?></b></h3>
                    <?php endforeach; ?>
                <?php endif; ?>
            </div>  
            </div>
