我想提高我在模塊開發的知識(這是遠離基本的),所以我試着開發周邊搜索模塊。 我已經取得了什麼現在包含表單塊:
function perimeter_search_block_view($delta = '') {
// Define an empty array for the block output.
$block = array();
switch($delta) {
case 'perimeter_search_box':
$block['subject'] = t('Perimeter search box');
$block['content'] = drupal_get_form('perimeter_search_form');;
break;
}
return $block;
}
/**
* Implementation of the perimeter search form
* @return array with form data
*/
function perimeter_search_form($form, &$form_state) {
$form = array(
'#action' => 'perimeter-search-results',
'keyword' => array(
'#type' => 'textfield'
),
'location' => array(
'#type' => 'textfield'
),
'perimeter' => array(
'#type' => 'select',
'#title' => t('Perimeter'),
'#options' => array('15 km', '30 km', '60 km', '120 km')
),
'submit' => array(
'#type' => 'submit',
'#value' => t('Start search')
)
);
return $form;
}
我也有一個函數來輸出搜索結果:
/**
* Implementation of hook_menu()
* @return defined menu/page items
*/
function perimeter_search_menu() {
$items = array();
// Search results page
$items['perimeter-search-results'] = array(
'title' => t('Perimeter search results'),
'page callback' => 'perimeter_search_results',
'access arguments' => array('view perimeter search'),
'type' => MENU_NORMAL_ITEM
);
return $items;
}
/**
* Processing job search queries
*/
function perimeter_search_results() {
$page_content = t('Search results');
return $page_content;
}
我的(?簡單)的問題是:如何在我perimeter_search_results()函數來獲取數據後(關鍵詞,位置,周長)?
