I followed this link to transform my exposed filter from textbox to dropdown list.
Use dropdown in views exposed filter on text fields with entity not node?
I make it work with a custom textfield.
I have problem to use the module with node title.
My code till now is:
<?php function views_dropdown_form_views_exposed_form_alter(&$form, &$form_state) { global $user; // Only alter forms with the necessary field if (isset($form['title'])) { // Build a query to get all node ids having the specified field $query = new EntityFieldQuery(); $results = $query->entityCondition('entity_type', 'node') ->entityCondition('bundle', 'rapporto_di_lavoro') ->propertyCondition('uid', $user->uid) ->propertyCondition('title', 'NULL', '!=') ->execute(); // Attach the field values to the nodes $ids = array_keys($results['node']); print_r($ids); print('<br>'); // Add a default so the filter is optional $options = array('' => '<select>'); // Buld the options array based on the query results, overwriting duplicate entries $query = db_select('node', 'n') ->fields('n', array('title')) ->condition('n.nid', $ids, 'IN'); $options = $query->execute()->fetchAll(); $op = json_decode(json_encode($options), true); print_r($op); print('<br>'); // Attach the field values to the nodes //$nodes = $results['node']; //field_attach_load('node', $nodes, FIELD_LOAD_CURRENT, array('field_id' => $field_id)); // Buld the options array based on the query results, overwriting duplicate entries //foreach($nodes as $nid => $node) { //$value = $node->field_cognome_l['und'][0]['value']; //$options2[$value] = $value; } //Alter the field $form['title']['#type'] = 'select'; $form['title']['#options'] = $op; $form['title']['#size'] = 1; } } I feel close to solution but I miss something.
On the picture I print four arrays.
Only the 4th was working when I tested the module with a custom field,
so probably I need to transform the 3rd array into the 4th.
