Having trouble getting the Repeater field to output my cards.


Recommended Posts

I was previously using individual fields to capture and output multiple cards onto my web page but after recently learning about repeaters would prefer to use this field type, as it will be a lot more user friendly for end users to create new cards. I tried to modify my code to grab the fields from the new Repeater field(s) but am getting this error message on the page:

Quote

: foreach() argument must be of type array|object, null given in C:\xampp\htdocs\dccdp\site\assets\cache\FileCompiler\site\templates\projects.php on line 27

Here is the code I'm currently trying to use for the cards:

<?php
// https://processwire.com/api/arrays/
// check if the array of images has items
foreach($page->tall_card as $card) {
  $count = 0;
  $count++;
  $options = array( 'quality' => 70 );
  $image = $card->image;
  $img = $card->image->size(550, 400, $options);
  $cardHeading = $card->title;
  $cardBody = $card->plain_paragraph;
  $raised = $card->raised_amount;
  $goal = $card->goal_amount;
  $link = $card->link;

  if ($raised == 0 ) :
  $percent = 0;
  else:
  $percent = $raised_amount / $goal_amount * 100;
  endif;

  if ($percent <= 5) :
  $percent = 0;
  endif;
?>

<span id="card<?php echo $count?>" class="card">

  <img class="cardThumb" src="<?php echo $img->url; ?>" alt="<?php echo $image->description; ?> Thumbnail" />

  <div class="cardBody">

    <div class="cardText">
      <h2><?php echo $cardHeading; ?></h2>
      <?php echo $cardBody; ?>
    </div>

    <div class="progressBarSection">
      <progress class="progressBar" id="progressbar<?php echo $count; ?>" value="<?php echo $percent; ?>" max="100"></progress>
      <span class="raisedAmount">
        $<?php echo $raised; ?> usd
      </span>
      <span class="goalAmount">
        $<?php echo $goal; ?> usd
      </span>
    </div>

    <div class="primaryBtn">
      <a href="https://www.paypal.com/donate?hosted_button_id=
               <?php echo $link; ?>
               &source=url">
        <button>
          <i class="fas fa-donate"></i> Donate
        </button>
      </a>
    </div>

  </div>

</span>

<?php
}
?>

Thanks in advance for any help!

Hi @spercy16!

Are you super sure tall_card is the name of your repeater field? It seems to be a non existent object.

Is the repeater set in the projects template? Maybe a screenshot of your template/repeater field config could help!

      Hi all,
      I could have sworn I used to be able to use the site generic 'title' field as a sub field of a repeater field. However I've tried to do this on two 3.0.165 sites recently and, while it will add the title field in the repeater field setup, it wont save the repeater title sub field's content when the repeater is used in a page template and edited.
      It;'s not a big issue but I wondered if this was a known restriction?

      I see old posts saying that repeaters are not the way to go in Custom Process Modules. If that is the case, when using forms (as I am trying to do) how would one tackle things like repeat contact fields where there can be multiple requirements for contact details with different parameters? (Like point of contact, director, etc) or even telephone numbers that have different uses?
      Just for background I am creating a process module that allows me to create types of financial applications in the admin area (no need to publish any of this, pure admin) that require a lot of personal or company information.
      Maybe I am thinking about this incorrectly?

      Coming from Perch (CMS) to Processwire, the one major downside I've found is that every place I want to insert content into my pages requires a single field (be that an image, integer, string, etc.). This can be a real pain to setup and manage if you have a lot of pages, many of them with dozens of unique fields. For example, on the Projects page of a site I'm working on right now I have to have fields for donate_amount (1-15, meaning fifteen unique fields that I have to duplicate manually), goal_amount(1-15), card_body(1-15), etc. After using Perch for a while, the way their system works is simply easier. You instead create your fields in a single PHP template (for every unique section, like a card) and their CMS imports those fields into the CMS when you choose to use that card, then you just fill in the values. You can also choose to reuse that card multiple times and each one you add gives you the several fields you need to fill in. So you can easily add your 15 cards, each with a picture, title, paragraph, and link, etc. and each one is basically given a unique ID that you can reference in your CSS files. If there's any way to make fields and templates work more like that, it would be a truly outstanding and efficient CMS. The great advantage of the way Perch is setup is that I can make a card with 10 fields, if need be, and easily duplicate that card out 40 times if I need 40 cards on the page and wouldn't need 10 fields for 40 cards (meaning in PW I would need 400 fields). If there's an easier way to do this in PW I would love to know, but as of right now, from what little I do know about the CMS 400 fields would be the only way to set that up, and that would be much more time consuming than if I could create one card (in PHP) with 10 fields that automatically added a number to the end of each field for each card (if that makes sense).

      Hi there,
      I'm probably missing something simple, but I'm just setting up my first site so I guess that's bound to happen.
      I've installed the LoginRegistration module and at first I was thinking that the confirmation emails weren't being sent. However I now see that new user confirmation emails are taking 20+ minutes to arrive. Is there a way to speed this up?
      Also the email is coming from processwire@mydomain - I couldn't found a place to change this.
      Any advice or help would be great!

      Never really got my head around field groups and it shows, In my module uninstall I think I figured out how to delete a page, then a template and it's fieldgroup so that nothing gets upset. But for fields that belong to templates that need to stoick around I'm still abit stuck to how you would remove the field and when I try I still get:
      Unable to delete field '[field name]' because it is in use by these fieldgroups: 'user'
      is there a tutorial or best method for removing added fields, pages and templates?
