Tag: fields

That's why I've created a custom display style that follows a tutorial and allows you to use fields. However, I can not figure out what the variables in the branch file should be to display the desired fields.

My PHP looks like this

class Slider extends StylePluginBase {



/ **
* {@inheritdoc}
* /
protected function defineOptions () {
$ options = parent :: defineOptions ();
$ options['path'] = array (& # 39; default & # 39; => & # 39; slider & # 39;);
return $ options;
}

/ **



* Does the style plugin itself support adding fields to its output?
*
* @var bool
* /
protected $ usesFields = TRUE;



/ **
* {@inheritdoc}
* /
public function buildOptionsForm (& $ form, FormStateInterface $ form_state) {
parent :: buildOptionsForm ($ form, $ form_state);

// path prefix for SLIDER links.

$ form['chooseImage'] = [
      '#title' => $this->t('Choose Image'),
      '#type' => 'select',
      '#description' => t('Choose where to position the title and text in the slider'),
      '#options' => ['cc' => $this->t('Center'), 'tl' => $this->t('Top Left')].
];

}

I create a topic function for the view.

Function slider_theme ($ existent, $ type, $ theme, $ path) {
Return Array (
& # 39; slider & # 39; => array (
& # 39; file & # 39; => & # 39; extended_display_styles.theme.inc & # 39 ;,

)
);
}

I can add options in the theme.inc advanced display styles file, but I do not know how to add the view variables.

    Function template_preprocess_views_view_slider (& $ variables) {
// Show user-defined options.


$ options = $ variable['view']-> style_plugin-> options;

// Create a two-dimensional array with years and months.
$ time_pool = array ();
$ frameArrayManual = array (& # 39; a & # 39 ;, & bgr ;, & # 39; c & # 39;);
// $ options['manual'] = $ Variables['view']-> style_plugin-> manual;

foreach ($ variable['view']-> result as $ id => $ result) {
$ created = $ result-> node_field_data_created;
$ created_year = date (& # 39; Y & # 39 ;, $ created);
// Date format of the month.
$ month_date_format = (isset ($ options['month_date_format']))? $ options['month_date_format'] : & # 39; m & # 39 ;;
$ created_month_digits = date (& # 39; m & # 39 ;, $ created);
$ created_month = date ($ month_date_format, $ created);
$ time_pool[$created_year][$created_month_digits]    = "$ created_month";
}

$ options['time_pool'] = $ time_pool;
$ options['frameArrayManual'] = Array (& # 39; a & # 39 ;, & bgr ;, & # 39; c & # 39;);

// Update the options for twig.
$ variable['options'] = $ options;
}

I can not find any resources to find out.
