How to print an entity bundle field from one with multiple values

Question

Struggling to find the answer to this. I have an entity called "school objects" which has a bundle called "homepage". One of the fields attached to this is called "Hero banners" and it allows multiple text values.

All I want to do is print each value. I don't need to check for conditions, I don't need NIDs, I just want each value. I am not really a php developer but understand the basics of what it is doing. I was looking into the EntityFieldQuery code, but cannot get anything to print on a tpl file I am using.

The output I need, based on image attached, is simply:

<div class="value_1">images/symbol.png</div>
<div class="value_2">Let's make a difference</div>
<div class="value_3">Start today</div>

All I can find after a lot of searching is complex bits of code checking for conditions and stuff that I do not need. I need some kind of array I think so that my template looks like:

<div class="value_1">Value[0]</div>
<div class="value_2">Value[1]</div>
<div class="value_3">Value[2]</div>

All I got so far is this:

query = new EntityFieldQuery();
$query->entityCondition('entity_type', 'school_objects')
  ->entityCondition('bundle', 'homepage')
  ->range(0, 14);
$result = $query->execute();

I have read the link to this on the Drupal site but cannot understand it or how to print what I need.

Answer 1

Try the following and load the actual entity to get its field values.

The code assumes you have drupals entityTypeManager injected via dependency injection. Otherwise use \Drupal::entityTypeManager() isntead of $this->entityTypeManager()

// Get the entity ids.
$entityIds = $this->entityTypeManager()->getStorage('school_objects')->getQuery()
  ->condition('type', 'homepage')
  // Add more conditions if you need.
  ->execute();
// I assume only one id is returned and reset the array. Otherwise go over 
// each Id with a foreach() and do this in a loop.
$entityId = reset($entityIds);
$schoolObject = $this->entityTypeManager()->getStorage('school_objects')->load($entityId);
// Now get the values of your field. I assume the fields machine_name is 'field_hero_banners'. Adjust if needed.
$values = $schoolObject->get('field_hero_banners')->getValue()
// Loop over all values.
foreach ($values as $item) {
  $value = $item['value'];
}

<?php
$wrapper = entity_metadata_wrapper('school_objects', '353', array('bundle' => 'homepage'));
$homepage_hero_banners = $wrapper->field_hero_banners->value();
?>
<p><?php echo $homepage_hero_banners[1]; ?></p>
<p><?php echo $homepage_hero_banners[2]; ?></p>

It has taken 4 days for me to get this code. I truly hope this helps someone else!
