Conditional (If) statements within structure

The CMS Questions

Hi there! Essentially what I’m after is that if there is a link in the structure field I want to display the word ‘(link)’ and link out to that URL. If there is no link in the structure field then I don’t want it to display anything. I’m pretty sure the solution I’m looking for is using an if statement or an e() statement? I am very new to Kirby so any help would be greatly appreciated! At the moment I can get the link to display using echo but if there is no link in the panel it still displays the text :sweat:

    <?php foreach ($page->press()->yaml() as $item): ?>
    <ul>
      <li><i><?php echo $item["title"];?></i>, <?php echo $item["publication"];?>, <a href="<?php echo $item["link"];?>">(link)</a></li>
     </ul>
 <?php endforeach ?>

It’s a bit easier with toStructure()

<ul>
    <?php foreach ($page->press()->toStructure() as $item): ?>

      <?php if ($item->link()->isNotEmpty()): ?>
      <li>
          <i><?= $item->title();?></i>, 
          <?= $item->publication() ;?>, 
          <a href="<?= $item->link();?>">(link)</a>
      </li>
      <?php endif ?>

 <?php endforeach ?>
</ul>

Your ul element has to be outside. the foreach loop, btw. Otherwise you. create a new list for each link.

If you only don’t want to. show the link, then. put the if statement around the a. tag.

You can just use common PHP controll structures.

<ul>
    <?php foreach ($page->press()->yaml() as $item): ?>
  <li>
    <i><?php echo $item["title"]; ?></i>, <?php echo $item["publication"]; ?>
      <?php if ($item["link"]): ?>
        ,<a href="<?php echo $item["link"]; ?>">(link)</a>
      <?php endif; ?>
  </li>
 <?php endforeach ?>
</ul>

Amazing! Thanks so much for your help. toStructure() seems like a better solution.

I still wanted to display the title and publication but omit the link if there was no link in the panel. So I moved the line <?php if ($item->link()->isNotEmpty()): ?> to after the title and publication variables and it’s working now. Thanks again!

  <ul>
    <?php foreach ($page->press()->toStructure() as $item): ?>
      <li>
        <i><?= $item->title();?></i>,
        <?= $item->publication() ;?>
        <?php if ($item->link()->isNotEmpty()): ?>
        <a href="<?= $item->link();?>">(link)</a>
      </li>
      <?php endif ?>

    <?php endforeach ?>
  </ul>
