Programmatically get View Custom Text

Question

I created a view with a "Custom text" field and want to get this field programmatically in Drupal 8.

I have:

$view = Views::getView('my_view');
$view->execute();
foreach($view->result as $row){
    $node = Node::load($row->nid);
    // Get here the view custom field with label "An example view field".
}

The $row field doesn't have the fields, nor the $node.

A screenshot of the view:

I now have:

$customField = $view->field['nothing'];

customField is an instance of Drupal\views\Plugin\views\field\Custom.

dpm($customField->render($row));

This returns class Drupal\views\Render\ViewsRenderPipelineMarkup with protectecd string with the same markup: {{ title }} test.

Thanks,

Please install the devel module

Go to /drupal8/devel/php

You can try:

$view = \Drupal\views\Views::getView('my_view');
$view->execute();

foreach($view->result as $row){
dpm($row->_entity->get('Custom text')->getValue());
}

note: change "Custom text" by machine name of the field

if your result is similar to:

Array
(
    [0] => Array
        (
            [value] => 43
        )

)

you can access the field with

$row->_entity->get('Custom text')->value

if your result is similar to:

Array
(
    [0] => Array
        (
            [target_id] => 1
        )

)

you can access the field with

$row->_entity->get('Custom text')->target_id

You should have something like

//already loaded
$node = $row->_entity;

Best way to get properties easily is probably to inspect variables with xdebug

If it is some king of header/footer, you can get the rendered array this way :

$view = \Drupal\views\Views::getView('Your view');
$view->execute();
/* @var $area \Drupal\views\Plugin\views\area\Text */
$area = reset($view->header); // $view->header['area'] or something else
$rendered = $area->render(); // rendered array

Ok, then :

$view = \Drupal\views\Views::getView('YOUR VIEW');
$view->execute('YOUR DISPLAY ID OR DEFAULT');
$nothing = $view->getHandler('YOUR DISPLAY ID OR DEFAULT','field', 'nothing');
$text = $nothing['alter']['text'];

You can also use hook_preprocess_views_view_field in order to change your custom text field:

function hook_preprocess_views_view_field(&$variables) {
  if ($variables["view"]->id() == "VIEW_ID" && $variables["field"]->options["id"] == "nothing") {
    $doYourCalculation = "New Text";
    $variables["output"] = ViewsRenderPipelineMarkup::create($doYourCalculation);
  }
}

Answer 4

This is what I have, however, I feel there must be a better way to do this.

Some notes:

• $view->render(); is critical, without it, it doesn't work
• 'nothing' is the default name of custom field, adding additional fields will result 'nothing_1', 'nothing_2', etc. You can see the name when hovering over the field (in the link) or in the replacement patterns.
• The value returned with a lot of \n in it. I'm replacing them here, but this can have unwanted side effects.

The code:

// The machine name of your view.
$viewname = 'name_of_the_view';

// Get the view.
$view = \Drupal\views\Views::getView($viewname);

// Display machine name.
$view->setDisplay('default');

// Execute the view.
$view->preExecute();
$view->execute();
$view->render();

foreach(array_keys($view->result) as $row_index){
  $custom_field = str_replace("\n", '', $view->field['nothing']->tokenizeValue((string)$view->field['nothing']->original_value, $row_index));
}

I had a similar problem and the only way worked for me was the following:

function MODULENAME_preprocess_views_view_fields(&$vars) {
  $view = $vars['view'];
  if(isset($view) && $view->id() === 'test') {
    foreach ($view->field as $id => $field) {
      // change the global custom text content for a specific
      // result row.
      if ($vars['row']->nid == 149) {
        $vars['fields']['nothing']->content = 'some new text';
      }
    }
  }
}

Answer 6

  $view = \Drupal\views\Views::getView( 'view_name' );
  $view->execute();
  foreach ($view->result as $row) {
  kint($row->_entity->get( 'nid' )->getValue()[0]['value']);
  }
