Php Magento cron作业表达式动态

我正在尝试在自定义模块中动态设置cron作业。但这不会将作业代码保存到cron_调度表中

  <config>
    <crontab>
    <jobs>
    <bookingreservation_summary>    
         <!--<schedule><cron_expr>*/5 * * * *</cron_expr></schedule>-->     
        <run><model>bookingreservation/observer::sendBookingSummaryEmail</model></run>
    </bookingreservation_summary>
    </jobs>
   </crontab>
 </config>

该类执行并保存到config_数据中

 class ABC_Bookingreservation_Model_Config_Backend_Cron extends Mage_Core_Model_Config_Data
    {
const CRON_STRING_PATH  = 'crontab/jobs/process_bookingreservation_summary/schedule/cron_expr';
const CRON_MODEL_PATH   = 'crontab/jobs/process_bookingreservation_summary/run/model';

/**
 * Cron settings after save
 *
 * @return Mage_Adminhtml_Model_System_Config_Backend_Log_Cron
 */
protected function _afterSave()
{
    $enabled    = $this->getData('groups/booking_summary/fields/enabled/value');
    $time       = $this->getData('groups/booking_summary/fields/time/value');
    $frequncy   = $this->getData('groups/booking_summary/fields/frequency/value');

    $frequencyDaily     = Mage_Adminhtml_Model_System_Config_Source_Cron_Frequency::CRON_DAILY;
    $frequencyWeekly    = Mage_Adminhtml_Model_System_Config_Source_Cron_Frequency::CRON_WEEKLY;
    $frequencyMonthly   = Mage_Adminhtml_Model_System_Config_Source_Cron_Frequency::CRON_MONTHLY;

    if ($enabled)
{
        $cronDayOfWeek = date('N');
        $cronExprArray = array(
            intval($time[1]),                                   # Minute
            intval($time[0]),                                   # Hour
            ($frequncy == $frequencyMonthly) ? '1' : '*',       # Day of the Month
            '*',                                                # Month of the Year
            ($frequncy == $frequencyWeekly) ? '1' : '*',        # Day of the Week
        );
        $cronExprString = join(' ', $cronExprArray);
    }
    else{

        $cronExprString = '';
    }

    try
    {
        Mage::getModel('core/config_data')
            ->load(self::CRON_STRING_PATH, 'path')
            ->setValue($cronExprString)
            ->setPath(self::CRON_STRING_PATH)
            ->save();

        Mage::getModel('core/config_data')
            ->load(self::CRON_MODEL_PATH, 'path')
            ->setValue((string) Mage::getConfig()->getNode(self::CRON_MODEL_PATH))
            ->setPath(self::CRON_MODEL_PATH)
            ->save();
    }
    catch (Exception $e)
    {
        Mage::throwException(Mage::helper('adminhtml')->__('Unable to save the cron expression.'));
    }
}

}

任何人都可以帮助解决我的代码的问题，因为每当我通过浏览器运行cron.php时，cron_scedule表都会更新，但不会保存此作业中的作业代码

您不需要保存run_模型（您已经将其声明为xml）

试试这个：

path:crontab/jobs/bookingrervation\u summary/schedule/cron\u expr

而不是：

路径：crontab/jobs/process\u bookingervation\u summary/schedule/cron\u expr

如果您没有解决此问题，请查看它如何工作sitemap模块的cron设置（它与您希望实现的功能相同）

取消对代码中的以下行的注释，然后查看它是否工作

 <!--<schedule><cron_expr>*/5 * * * *</cron_expr></schedule>-->

我认为这可能有用……如果有用，请告诉我。

你曾经解决过这个问题吗？如果是，你需要做什么才能让它工作？找到了这个优秀而简洁的方法，无需额外的代码（对于未来的谷歌用户）：

 <!--<schedule><cron_expr>*/5 * * * *</cron_expr></schedule>-->
