drupal搜索功能扩展
hook_search是用来扩展你搜索功能的hook，在我的术语收藏模块中，要想对术语进行搜索，可进行如下实现。搜索表单的样式我们可以用 hook_form_alter($form_id, &$form)来修改，判断当form_id为搜索表单id时候，对form主题进行覆写。而搜索结果的定制可以使用 hook_search_page($rows)来做，比如我要对搜索结果进行表格格式化输出，代码如下：
<?php
/*
* Implemention of hook_search().
*/
function favorite_terms_search($op = ‘search’, $keys = NULL) {
switch ($op) {
case ‘name’:
if (user_access(‘favorite terms search’)) {
return t(‘Terms’);
}
case ‘search’:
if (user_access(‘favorite terms search’)) {
$header = array(t(‘Term’), t(‘Description’), t(‘Operations’));
// Return to this page after an ‘add favorite’ operation.
$destination = drupal_get_destination();
// Replace wildcards with MySQL/PostgreSQL wildcards.
$keys = preg_replace(‘!\*+!’, ‘%’, $keys);
$sql = "SELECT * FROM {term_data} WHERE LOWER(name) LIKE LOWER(‘%%%s%%’)";
$result = pager_query($sql, 20, 0, NULL, $keys);
while ($term = db_fetch_object($result)) {
$rows[] = array(
l($term->name, "taxonomy/term/$term->tid"),
check_plain($term->description),
l(t(‘add to favorites’), "favorite_terms/add/term/$term->tid", array(), $destination)
);
}
if (!$rows) {
$rows[] = array(array(
‘data’ => t(‘No matched term found.’),
‘colspan’ => ’3′)
);
}
return $rows;
}
}
}
function favorite_terms_search_page($rows) {
drupal_add_css(drupal_get_path(‘module’, ‘favorite_terms’) . ‘/favorite_terms.css’);
$header = array(t(‘Term’), t(‘Description’), t(‘Operations’));
$output = theme(‘table’, $header, $rows);
$output .= theme(‘pager’, NULL, 50, 0);
$output .= ‘<div class="search_page_add_new">’;
$output .= t(‘if you did not find a product above, click !here to add a new product’, array(‘!here’ => l(t(‘here’), ‘node/add/product’)));
$output .= ‘</div>’;
return $output;
}
?>
