我在表單alter中添加了一些自動完成功能。問題是，在回調中，只有文本字段中的字符串自動完成處於打開狀態，可用。我也想從回調中的另一個文本字段獲取值。這怎麼可能 ？Drupal自動完成，具有多個參數的回調
/**
* Implements hook_form_alter().
*/
function webform_conversion_jquery_form_webform_client_form_1_alter(&$form, &$form_state, $form_id) {
//Load some extra function to process data
module_load_include('inc', 'webform_conversion_jquery', '/includes/dataqueries');
//Add extra js files
drupal_add_js(drupal_get_path('module', 'webform_conversion_jquery') . '/js/conversionform.js');
$form['submitted']['correspondentadress']['cor_street']['#autocomplete_path'] = 'conversionform/conversion_street';
}
}
/**
* Implements hook_menu().
*/
function webform_conversion_jquery_menu() {
$items = array();
$items['conversionform/conversion_street'] = array(
'title' => 'Conversion street autocomplete',
'page callback' => 'conversion_street_autocomplete',
'access callback' => 'user_access',
'access arguments' => array('access content'),
'type' => MENU_CALLBACK,
);
return $items;
}
/**
* Retrieve a JSON object containing autocomplete suggestions for streets depending on the zipcode.
*/
function conversion_street_autocomplete($street = '') {
$street = "%" . $street . "%";
$matches = array();
$result = db_select('conversion_adresslist')
->fields('conversion_adresslist', array('street'))
->condition('street', $street, 'like')
->execute();
foreach ($result as $street) {
$matches[$street->street] = $street->street;
}
drupal_json_output($matches);
}
我只是希望能夠在功能上張貼額外的信息：
conversion_street_autocomplete($street = '', $extraparameter)
