To get settings of an Entity field in Drupal 8 Use this code: $entity_type='node'; $bundle='article'; $field_name='field_summary_image'; $bundle_fields = \Drupal::getContainer()->get('entity_field.manager')->getFieldDefinitions($entity_type, $bundle); $field_definition = $bundle_fields[$field_name]; $file_directory= $field_definition->getSetting('file_directory');

To run some jQuery code before the Ajax button submit use beforeSubmit function Drupal . behaviors . exampleModule = { attach : function ( context , settings ) { // ELEMENT_ID must not include the # Drupal . ajax [ 'ELEMENT_ID' ]. options . beforeSubmit = function ( form_values , element_settings , options ) { // code here }; } };

You might get this error Uncaught TypeError: a.indexOf is not a function at r.fn.init.r.fn.load (jquery.min.js?v=3.2.1:4) at Object.attach (scripts.js?v=8.4.0:1) at Object.Drupal.attachBehaviors (drupal.js?v=8.4.0:25) at drupal.init.js?v=8.4.0:16 at HTMLDocument.t (ready.min.js?v=1.0.8:4) Drupal 8.4  is using latest jQuery version 3.2 which does not support load() function.

You can do this using hook_feeds_presave to check the data prior to it being saved. $item   parameter contains the current feed.  Check item on some condition. To skip an item to being import, use $entity->feeds_item->skip = TRUE; function mymodule_feeds_presave ( FeedsSource $source , $entity , $item ) { // check that this is fired only for the importer being used if ( $source -> importer -> id == 'my_custom_feeds_importer' ){ if ( $item [ 'mfgcode' ] < '18' ){ $entity -> feeds_item -> skip = TRUE ; drupal_set_message ( t ( "Skipping item" , 'warning' ); } } }

Using Drupal batch API we can create batch processes. // form submit. function product_display_submit($form, &$form_state) { $products = $form_state['input']['product_table']; if (!empty($products)) { // Remove empty values. $emptyRemoved = remove_empty($products); // re-index array. $myarray = array_values($emptyRemoved); $progress = 0; // where to start $max = count($myarray); // how many records to process until stop. // Tell Drupal about the batch process. $batch = array( 'operations' => array(), 'finished' => 'product_display_batch_finished', // runs after batch is finished 'title' => t('Deleting products'), 'init_message' => t('Beginning product delete'), 'progress_message' => t('Deleted @current out of @total'), 'error_message' => t('Product deletion failed.'), ); //

hook_rules_condition_info() is used to create custom rules conditions. /** * Implements hook_rules_condition_info() */ function custom_rules_rules_condition_info() { return array( 'custom_rules_default_condition_dealer_store' => array( 'label' => t('Dealer store'), 'group' => t('Domains'), 'parameter' => array( 'operator' => array( 'type' => 'text', 'label' => t('Show pricing enabled'), 'options list' => '__custom_rules_dealer_store_operators', 'default value' => '0' ) ) ), ); } /** * Custom hook * Test domain for matching * @param string $operator * @return bool */ function custom_rules_default_condition_dealer_store($operator) { $domain_info = domain_get_domain(); // returns 0 or 1. // 1 means current domain is dealer store.

Map XML feeds on some basic conditions without using feeds tamper module First, take a look at an example <images>    <image type="file">https://s3.amazon.com/example1.pdf</image>    <image type="file">https://s3.amazon.com/example3.pdf</image>    <image type="file">https://s3.amazon.com/example2.pdf</image>    <image type="image">https://s3.amazon.com/example.jpg</image> </images> Case 1 : If you want to import only those feeds that has type "image" then your XML Parser settings should be like Images/Image[./@type = 'image'] Case 2 : Import feeds that has not file type then Images/Image[./@type != 'file'] Example 2:   < item > < enclosure url = " http://www.example.com/path-to-image/image1.jpg " type = " image/jpeg " /> < enclosure url = " http://www.example.com/path-to-image/image2.jpg
