I created a custom cck field that shows links to mapping sites. It can be used with content types that have a physical address. The widget is just a checkbox, that tells if mapping links should be shown or not for this particular node.
I am definitely doing something wrong because the value of this checkbox is not saved or loaded properly from the database.
I also asked for help on the main drupal forum:
http://drupal.org/node/150266
The module is See Map:
http://drupal.org/project/see_map
And here is the widget code:
<?php
// hook_widget_info
function see_map_widget_info() {
return array(
'see_map_checkbox' => array(
'label' => '"See Map" links',
'field types' => array('see_map'),
),
);
}
// hook_widget_settings
function see_map_widget_settings($op, $widget) {
switch ($op) {
case 'validate':
if ($widget['required'] == 1) {
form_set_error('required', t('See Map field cannot be required!'));
}
if ($widget['multiple'] == 1) {
form_set_error('multiple', t('See Map field cannot have multiple values!'));
}
break;
}
}
// hook_widget
function see_map_widget($op, &$node, $field, &$items) {
switch ($op) {
case 'form':
$form = array();
$default_value = 0;
if (isset($field['widget']['default_value'][0]['show_see_map'])) {
$default_value = $field['widget']['default_value'][0]['show_see_map'];
}
$form[$field['field_name']][0]['show_see_map'] = array(
'#type' => 'checkbox',
'#title' => t('Show "!seemap" links.', array('!seemap' => $field['widget']['label'])),
'#default_value' => isset($items[0]['show_see_map']) ? $items[0]['show_see_map'] : $default_value,
'#required' => FALSE,
'#description' => $field['widget']['description'],
);
return $form;
}
}
?>Any suggestions or pointers to relevant documentation or similar modules are more than appreciated.
Thanks,
Marius
