我在主题functions.php文件中在wordpress中创建了以下函数。我想在我的主题模板中调用此函数,并在我的主题模板中回显foreach部分。我到底该怎么做?我认为我必须从函数中返回一些东西,但我不知道如何设置它。非常感谢您的帮助。
function geography_navigation($type, $field1, $field2, $field3, $field4, $field5) {
global $wpdb;
$results = $wpdb->get_results("SELECT DISTINCT wp_eva_geography.$field1, wp_eva_geography.$field2
FROM wp_eva_geography
WHERE wp_eva_geography.$field3='$type' AND wp_eva_geography.$field4='$geo_no_dash';");
echo "<ul>";
foreach($results as $geography){
echo "<li> <a href='/$type/$field5/{$geography->$field2}/'>{$geography->$field1}</a></li>";
}
echo "</ul>";
}

将输出设置为变量并按如下方式返回:
function geography_navigation($type, $field1, $field2, $field3, $field4, $field5)
{
global $wpdb;
$results = $wpdb->get_results("SELECT DISTINCT wp_eva_geography.$field1, wp_eva_geography.$field2
FROM wp_eva_geography
WHERE wp_eva_geography.$field3='$type' AND wp_eva_geography.$field4='$geo_no_dash';");
$output = '<ul>';
foreach($results as $geography)
{
$output .= "<li> <a href='/$type/$field5/{$geography->$field2}/'>{$geography->$field1}</a></li>";
}
return $output . '</ul>';
}
请注意我已对此进行过测试,但相信它应该有效......请告诉我!
