Wordpress echo something in for loop only once

Question

So I'm trying to print some labels only once, there are four labels per loop.

So esentially i'm trying to loop through and print the labels once per label.

At the second it is printing the four labels per loop.

To better explain here are some pictures.

Here is my code

  <div class="wpt_test fill_form">

    <div class="answers">

        <?php endforeach; ?>>
        <?php if ($isShowContent): ?><div class="content" style="margin:0;"><?php echo $content ?></div><?php endif ?>    
        <?php if ($shortDescription): ?><div class="short-description"><?php echo $wp->autoParagraphise($shortDescription) ?></div><?php endif ?>

Answer 1

By no means is this a copy-paste solution. There are variables in your code that I don't know what they contain but this should serve as a potential idea for the solution. Essentially the desired result is a "table" of data. Whether you use a table or divs to construct the HTML structure is on you. You could use a layout such as those provided by bootstrap or foundation or another CSS framework. This example simply uses a table to provide the structure. You will want to draw your answer labels out into a container such as an array for iteration in the table head. You may then present each answer with simply the input and not concern yourself with whether or not to print it on each iteration. Hope this helps!

<?php
/**
 * @var array $answerLabels
 * @var WpTesting_Model_Question[] $questions
 */
?>
<table>
    <thead>
        <tr>
            <td></td>
            <?php foreach ($answerLabels as $label): ?>
                <td><?= $label ?></td>
            <?php endforeach; ?>
        </tr>
    </thead>
    <tbody>
        <?php foreach ($questions as $question): ?>
            <tr>
                <td><?= $question->getTitle() ?></td>
                <?php foreach ($question->buildAnswers() as $index =>     $answer):
                    $answerId = 'wpt-test-question-' . $question->getId() . '-answer-' . $answer->getId(); 
                ?>
                    <td>
                        <label for="<?= $answerId ?>">
                            <input type="<?= $isMultipleAnswers ? 'checkbox' : 'radio' ?>"    
                                   id="<?= $answerId ?>"
                                   data-errormessage="<?= $isMultipleAnswers
                                       ? __('Please select at least one answer.', 'wp-testing')
                                       : __('Please choose only one answer.', 'wp-testing') ?>"
                                <?php if (0 == $index): ?>
                                    required="required"
                                    aria-required="true"
                                <?php endif ?>
                                   name="<?= $answerIdName ?>[<?= $answerIndex ?>]"
                                   value="<?= $answer->getId() ?>"/>
                        </label>
                    </td>
                <?php endforeach; ?>
            </tr>
        <?php endforeach; ?>
    </tbody>
</table>

Answer 2

I managed to fix this using a reset.

<?php if($i==0): ?>

<?php foreach($question->buildAnswers() as $a => $answer): /* @var $answer WpTesting_Model_Answer */ ?>

<?php $answerId = 'wpt-test-question-' . $question->getId() . '-answer-' . $answer->getId() ?>

<label for="<?php echo $answerId ?>"> <?php echo $answer->getTitleOnce(); ?></label>

<?php if ($isMultipleAnswers) {$answerIndex++;} ?>

<?php endforeach ?>

<?php $i = 1; ?>

<?php endif; ?>

Answer 3

Actually you are doing wrong, because you are printing the label with input.

you may first print the label static and then you should print as

foreach input display inline

you can also use table <tr> <td> for properly align the inputs.
