[pcsh lang="php" tab_size="4" message="" hl_lines="" provider="manual"]
/**
* 获取WordPress所有分类名字和ID
*/
function show_category(){
global $wpdb;
$request = "SELECT $wpdb->terms.term_id, name FROM $wpdb->terms ";
$request .= " LEFT JOIN $wpdb->term_taxonomy ON $wpdb->term_taxonomy.term_id = $wpdb->terms.term_id ";
$request .= " WHERE $wpdb->term_taxonomy.taxonomy = 'category' ";
$request .= " ORDER BY term_id asc";
$categorys = $wpdb->get_results($request);
foreach ($categorys as $category) { //调用菜单
$output = '<span>'.$category->name."(<em>".$category->term_id.'</em>)</span>';
echo $output;
}
}
[/pcsh]
其中使用‘->’获取表名,使用‘.’点号获取列名,使用‘,’逗号分割不同的列名
