Struggling with booleans and structure fields

Kirby 2 Solved ✅
1

I’m very new to php and even if i try my best i’m facing an issue i’m not resolving for hours now.

Here is a template section :

<section class="yaml yaml-conferences">
    <h1>Les conférences :</h1>

    <?php $conferences = yaml($page->conferences()) ?>
    <?php foreach($conferences as $conference): ?>
        <article class="listitem">
            <img src="<?php echo $page->image($conference['logoimg'])->url() ?>" alt="<?php echo $conference['nom'] ?>" />
            <h2><?php echo $conference['nom'] ?></h2>
            <p>Se déroulera le : <?php echo $conference['date'] ?> à <?php echo $conference['heure'] ?></p>
            <p><?php echo $conference['intervenant'] ?></p>
            <p><?php echo $conference['presentation'] ?></p>
        </article>
    <?php endforeach ?>
</section>

And then a chunk of my blueprint :

  logo:
    label: Image associée ?
    type: toggle
    text: on/off
    width: 1/2
  logoimg:
    label: Nom de l'image
    type: text
    help: Utilisez le nom de l'image insérée précédemment dans le gestionnaire de fichiers de la page.
    width: 1/2

My issue here is i want to conditionally load or not the logoimg with either the fact is the field is empty or not… OR via a toggle button in the structure field.
But, i tried the boolean method, i tried many things without any success… It seems any thing i can try is worthless. Please help.

I managed to make it “sorta work” but i feel the code is ugly and wrong in many ways, is someone here can help me? I used the toStructure instead of a yaml but i really don’t feel the difference and this might be overkill.

<section class="yaml yaml-conferences">
    <h1>Les conférences :</h1>

    <?php $conferences = yaml($page->conferences()) ?>
    <?php foreach($conferences as $conference): ?>
        <article class="listitem">
            <?php foreach($page->conferences()->toStructure() as $verif): ?>
                <?php if($verif->logo()->bool()): ?>
                    <img src="<?php echo $page->image($conference['logoimg'])->url() ?>" alt="<?php echo $conference['nom'] ?>" />
                <?php endif ?>
            <?php endforeach ?>
            <h2><?php echo $conference['nom'] ?></h2>
            <p>Se déroulera le : <?php echo $conference['date'] ?> à <?php echo $conference['heure'] ?></p>
            <p><?php echo $conference['intervenant'] ?></p>
            <p><?php echo $conference['presentation'] ?></p>
        </article>
    <?php endforeach ?>
</section>

Also, i don’t understand the purpose of the yaml() method, why using it while you can use toStructure() ? It seems to not break kirby features. (again, i’m totally naive in this subject, i am a front-end dev so…)

Well… i am dumb.

<section class="yaml yaml-conferences"><h1>Les conférences :</h1>

    <?php $conferences = yaml($page->conferences()) ?>
    <?php foreach($conferences as $conference): ?>
        <article class="listitem">
            <h2><?php echo $conference['nom'] ?></h2>
            <?php if(!empty($conference['logoimg'])): ?>
                <img src="<?php echo $page->image($conference['logoimg'])->url() ?>" alt="<?php echo $conference['nom'] ?>" />
            <?php endif ?>
            <p>Se déroulera le : <?php echo $conference['date'] ?> à <?php echo $conference['heure'] ?></p>
            <p><?php echo $conference['intervenant'] ?></p>
            <p><?php echo $conference['presentation'] ?></p>
        </article>
    <?php endforeach ?>
</section>

It work and this is even simplier than before.
Tried the “isset” but did not work, used an !empty

yaml parses the data into an array structure, while toStructure supports the Kirby method syntax.
It allows you to use if($conference->logoimg()) without using empty for example.

But generally your new code looks good.

Thanx, i learn a little more everyday ^^
So, why i see everywhere the yaml() method while toStructure seems to be more elegant?

If toStructure allow more usages i dont see why using yaml() to make an array is useful, it only make code more confusing to me (again, i’m a total newbie so, i miss something obviously).

yaml is a Kirby feature for a longer time now. The toStructure method has been added together with the “structure” Panel field not long ago.

yaml can be useful because arrays are generally easier to parse if you don’t know the structure in advance.

This is exactly for what I’m looking for, but it doesn’t work :cry:

Part of my blueprint:
timefrom_am: label: Von type: time

Part of my snippet code:
<?php $var = "$item->timefrom_pm()"; #$var = "$openinghours->timefrom_pm()"; if($var) { echo "times"; }

Wether $var1 or $var2 it’s always the same (wrong) php output, but the data aren’t definitely the same:

Thanks for help!

Best,
Andreas

Could you pls. post your complete code? What are the quotation marks around $item-> timeframe_pm() etc. doing there ?

This is the complete code. I just changed the question marks cause of markdown. Now everything is like in my code:

My content file: openinghours.txt

Title: Öffnungszeiten
----

Openinghours: 

- 
  weekday: Montag
  timefrom_am: 09:00
  timeto_am: 12:00
  timefrom_pm: 14:00
  timeto_pm: 18:00
- 
  weekday: Dienstag
  timefrom_am: 09:00
  timeto_am: 12:00
  timefrom_pm: 14:00
  timeto_pm: 18:00
- 
  weekday: Mittwoch
  timefrom_am: 09:00
  timeto_am: 12:00
  timefrom_pm:
  timeto_pm:

My blueprint openinghours.php

<?php if(!defined('KIRBY')) exit ?>

title: Page
fields:
  title:
    label: Title
    type:  text
  openinghours:
    label: Öffnungszeiten
    type: structure
    entry: >
      <h2>{{label}}</h2>
      <time itemprop="openingHours" datetime="{{weekday}} {{timefrom_am}} {{timeto_am}}, {{timefrom_pm}} {{timeto_pm}}">
        <span>{{weekday}}</span>
        {{timefrom_am}}&thinsp;–&thinsp;{{timeto_am}}&thinsp;Uhr + {{timefrom_pm}}&thinsp;–&thinsp;{{timeto_pm}}&thinsp;Uhr
      </time>
    fields:
      weekday:
        label: Wochentag
        type: select
        options:
          Montag: Montag
          Dienstag: Dienstag
          Mittwoch: Mittwoch
          Donnerstag: Donnerstag
          Freitag: Freitag
      timefrom_am:
        label: Von
        type: time
        width: 1/2
      timeto_am:
        label: Bis
        type: time
        width: 1/2
      line:
        type: line
      timefrom_pm:
        label: Von
        type: time
        width: 1/2
      timeto_pm:
        label: Bis
        type: time
        width: ½

And my snippet opening hours.php

<?php $page = page('opening-hours'); ?>

<?php foreach($page->openinghours()->toStructure() as $item):
  $var = '$item->timefrom_pm()';
  ?>

  <time itemprop="openingHours" datetime="<?php echo $item->weekday() ?> <?php echo $item->timefrom_am(); ?> <?php echo $item->timeto_am(); ?>">
    <span><?php echo $item->weekday() ?></span>
    <?php echo $item->timefrom_am(); ?>&thinsp;–&thinsp;<?php echo $item->timeto_am(); ?>&thinsp;Uhr
    <?php
      if($var) {
        echo "nothing"; ?>
        + <?php echo $item->timefrom_pm(); ?>&thinsp;–&thinsp;<?php echo $item->timeto_pm(); ?>&thinsp;Uhr
      <?php
      }
    ?>
  </time>
  <hr />
<?php endforeach ?>

Thanks a lot!

Best,

You shouldn’t put quotes around your variable definitions, otherwise you get the literal string, not the value of the variable. Instead use this:

$var = $item->timefrom_pm();
11

This will work:

<?php $page = page('openinghours'); ?>
<?php foreach($page->openinghours()->toStructure() as $item):
  $var = $item->timefrom_pm()->value();
?>

  <time itemprop="openingHours" datetime="<?php echo $item->weekday() ?> <?php echo $item->timefrom_am(); ?> <?php echo $item->timeto_am(); ?>">
    <span><?php echo $item->weekday() ?></span>
    <?php echo $item->timefrom_am(); ?>&thinsp;–&thinsp;<?php echo $item->timeto_am(); ?>&thinsp;Uhr
    <?php
      if($var) { echo "+ " . $item->timefrom_pm() . "&thinsp;–&thinsp;" . $item->timeto_pm() . "&thinsp;Uhr" ; } ?>
  </time>
  <hr />
<?php endforeach ?>
