首先,我是wordpress和PHP的新手.我想要一个奖励模块,我可以有多个类别,每个类别有多个获奖者.
我已经在CI(CodeIgniter)中实现了这一点,但现在想在wordpress中实现类似的东西.我可以在哪里有一个类别,那个类别可以有多个获胜者,各自的位置.我将能够执行简单的crud功能.
有什么建议可以在wordpress中实现这个模型,或者是否有任何插件可用,功能有些类似？
我应该为此创建自己的插件,并且一开始我尝试过这个
$your_db_name = $wpdb->prefix . 'your_db_name';
// function to create the DB / Options / Defaults
function your_plugin_options_install() {
global $wpdb;
global $your_db_name;
// create the ECPT MetaBox database table
if($wpdb->get_var("show tables like '$your_db_name'") != $your_db_name)
{
$sql = "CREATE TABLE " . $your_db_name . " (
`id` mediumint(9) NOT NULL AUTO_INCREMENT,
`field_1` mediumtext NOT NULL,
`field_2` tinytext NOT NULL,
`field_3` tinytext NOT NULL,
`field_4` tinytext NOT NULL,
UNIQUE KEY id (id)
);";
require_once(ABSPATH . 'wp-admin/includes/upgrade.PHP');
dbDelta($sql);
}
}
// run the install scripts upon plugin activation
register_activation_hook(__FILE__,'your_plugin_options_install');
有什么建议？提前致谢 解决方法: 无需创建自定义数据库表来执行此操作.
> Register a custom post type奖项,包括一些功能(标题,编辑和图像).
>添加metabox以处理获奖者(registered users).
>附上custom taxonomy奖品.
>使用它,您可以使用默认的WP_Query功能并创建常规主题模板或小部件或短代码来输出结果.
有很好的插件来管理CPT和自定义字段使这很容易,但这里是上面列出的小插件：
