I have a form, which is a view with exposed filters.
In that 2 of the exposed filters are taxonpmy term references. Based on the selection of the first, need to change the options in the second select.
since the form is already built,. started with a form alter, with
The first select :
$options_first = _get_states_for_select();
$selected = isset($form_state['input']['field_tpcc_lice_locstate_tid']) ? $form_state['input']['field_tpcc_lice_locstate_tid'] : key($options_first);
$form['field_tpcc_lice_locstate_tid']['#options'] = $options_first;
$form['field_tpcc_lice_locstate_tid']['#default-value'] = $selected;
$form['field_tpcc_lice_locstate_tid']['#ajax'] = array(
'callback' => 'select_callback',
'wrapper' => 'type_replace',
);Then the second select
$form['field_tpcc_lice_lictype_tid']['#prefix'] = '<div id="type_replace">';
$form['field_tpcc_lice_lictype_tid']['#suffix'] = '</div>';
$form['field_tpcc_lice_lictype_tid']['#options'] = _get_lic_type_options($selected);
$form['field_tpcc_lice_lictype_tid']['#default-value'] = isset($form_state['input']['field_tpcc_lice_lictype_tid']) ? $form_state['input']['field_tpcc_lice_lictype_tid'] : '';The call back simply returns the second select again:
function select_callback($form, $form_state) {
return $form['field_tpcc_lice_lictype_tid'];
}The helper functions return assocative arrays (these are fine).
function _automobile_get_manufacturer_dropdown_options() {
//returns an assc array
}function _get_lic_type_options($key = '') {
//returns an assoc array
}When first select is clicked, an ajax call is initialised, but geting an error in the popup(overlay)
An AJAX HTTP error occurred.
HTTP Result Code: 200
