我目前正在尝试创建一个wordpress插件，在那里我可以交易比特币。我应该创建一个cron作业，以便检查从一些API调用中获得的值，但我的cron作业没有正确激活。

我还试着做一些随机的“回显”，看看问题是否出在我的API代码上，但我认为问题在于wordpress没有激活我的cron作业。

这是我的代码：

    function my_activation() {
    if (!wp_next_scheduled ( \'my_periodic_event\' )) {
    wp_schedule_event(time(), \'thirtysec\', \'my_periodic_event\');
    }
    add_action(\'my_periodic_event\', \'checkCurrencyValue\');
}

    function checkCurrencyValue() {
        global $market, $quantita, $durata, $wpdb, $table_name;
        $table_name = $wpdb->prefix."bittrex_account_info";
        $users = $wpdb->get_results( "SELECT chiave FROM $table_name");
                    // The query will get the complete users login id/login name
        foreach ( $users as $user ) {
        echo $user->chiave;
        }
        $users = $wpdb->get_results( "SELECT chiave FROM $table_name WHERE email = \'[email protected]\'");
        $wpdb->update( $table_name, array( \'chiave\' => $key, \'secret\' => $users),array(\'email\'=>\'[email protected]\'));

        $d = new BittrexxApi ($key, $secret);
        $quantita = $wpdb->get_var("SELECT quantita FROM wp_bittrex_account_info WHERE email = \'$mail\'");
        $discesaMax = $wpdb->get_var("SELECT discesaMax FROM wp_bittrex_account_info WHERE email = \'$mail\'");
        $maxValDol = $wpdb->get_var("SELECT maxvaldol FROM wp_bittrex_account_info WHERE email = \'$mail\'");
        $summ = $d->getMarketSummary("USDT-BTC");
        if($summ<discesaMax){
            //$balance = $d->buyLimit($market, $quantita, $durata);
        }
        else if($summ>maxValDol){
            //$balance = $d->sellLimit($market, $quantita, $durata);
        }       
}

我的寄存器挂钩正在工作：执行My\\u activation（）函数，但不执行checkCurrencyValue（）函数。有什么问题吗？

提前谢谢你，菲利波
