The cron job feature provided by\u00a0Magento 2\u00a0allows scheduling activities to be executed at a particular time. Magento 2 store owners can set a specific time for carrying out such automated tasks according to their requirements.<\/p>\n\n\n\n

However, the store owner needs an additional cron job that can work in the custom modules as certain custom features like a newsletter, backup scheduling, google sitemaps, etc require a cron job.<\/p>\n\n\n\n

For instance, you\u2019ve created a module that works on backup your store. In such a scenario, it is troublesome to configure or run the backup manually whenever you need. What if you require to backup your whole store based on the hours? Is it possible to wait for a determined time and backup the store manually?<\/p>\n\n\n\n

No, it is time-consuming. Right? In that case, use a quick way to dynamically schedule cron job in Magento 2 system configuration!<\/p>\n\n\n\n

Method to Dynamically Schedule Cron Job in Magento 2 System Configuration<\/h2>\n\n\n\n

1. Add the below code in the system.xml<\/strong> file at Vendor\/Extension\/etc\/adminhtml<\/strong><\/p>\n\n\n\n

<group id=\"cronScheduled\" translate=\"label\" type=\"text\" sortOrder=\"20\" showInDefault=\"1\" showInWebsite=\"1\"\n       showInStore=\"1\">\n    <label>Backup Scheduled<\/label>\n    <field id=\"frequency\" translate=\"label\" type=\"select\" sortOrder=\"1\" showInDefault=\"1\" showInWebsite=\"1\"\n           showInStore=\"1\">\n        <label>Frequency<\/label>\n        <source_model>Magento\\Cron\\Model\\Config\\Source\\Frequency<\/source_model>\n        <backend_model>Vendor\\Extension\\Model\\Config\\CronConfig<\/backend_model>\n    <\/field>\n    <field id=\"time\" translate=\"label comment\" sortOrder=\"2\" type=\"time\" showInDefault=\"1\" showInWebsite=\"1\"\n           showInStore=\"1\">\n        <label>Start Time<\/label>\n    <\/field>\n<\/group><\/pre>\n\n\n\n
2. Use the below code in the CronConfig.php<\/strong> at Vendor\/Extension\/Model\/Config\/<\/strong><\/strong><\/p>\n\n\n\n
<?php\n\nnamespace Vendor\\Extension\\Model\\Config;\n\nclass CronConfig extends \\Magento\\Framework\\App\\Config\\Value\n{\n    const CRON_STRING_PATH = 'crontab\/default\/jobs\/vendor_extension_cron_job\/schedule\/cron_expr';\n\n    const CRON_MODEL_PATH = 'crontab\/default\/jobs\/vendor_extension_cron_job\/run\/model';\n\n    protected $_configValueFactory;\n\n    protected $_runModelPath = '';\n\n    public function __construct(\n        \\Magento\\Framework\\Model\\Context $context,\n        \\Magento\\Framework\\Registry $registry,\n        \\Magento\\Framework\\App\\Config\\ScopeConfigInterface $config,\n        \\Magento\\Framework\\App\\Cache\\TypeListInterface $cacheTypeList,\n        \\Magento\\Framework\\App\\Config\\ValueFactory $configValueFactory,\n        \\Magento\\Framework\\Model\\ResourceModel\\AbstractResource $resource = null,\n        \\Magento\\Framework\\Data\\Collection\\AbstractDb $resourceCollection = null,\n        $runModelPath = '',\n        array $data = []\n    )\n    {\n        $this->_runModelPath = $runModelPath;\n        $this->_configValueFactory = $configValueFactory;\n        parent::__construct($context, $registry, $config, $cacheTypeList, $resource, $resourceCollection, $data);\n    }\n\n\n    public function afterSave()\n    {\n        $time = $this->getData('groups\/cronScheduled\/fields\/time\/value');\n        $frequency = $this->getData('groups\/cronScheduled\/fields\/frequency\/value');\n\n        $cronExprArray = [\n            intval($time[1]),\n            intval($time[0]),\n            $frequency == \\Magento\\Cron\\Model\\Config\\Source\\Frequency::CRON_MONTHLY ? '1' : '*',\n            '*',\n            $frequency == \\Magento\\Cron\\Model\\Config\\Source\\Frequency::CRON_WEEKLY ? '1' : '*',\n        ];\n\n        $cronExprString = join(' ', $cronExprArray);\n\n        try {\n            $this->_configValueFactory->create()->load(\n                self::CRON_STRING_PATH,\n                'path'\n            )->setValue(\n                $cronExprString\n            )->setPath(\n                self::CRON_STRING_PATH\n            )->save();\n            $this->_configValueFactory->create()->load(\n                self::CRON_MODEL_PATH,\n                'path'\n            )->setValue(\n                $this->_runModelPath\n            )->setPath(\n                self::CRON_MODEL_PATH\n            )->save();\n        } catch (\\Exception $e) {\n            throw new \\Exception(__('We can\\'t save the cron expression.'));\n        }\n\n        return parent::afterSave();\n    }\n}<\/pre>\n\n\n\n
3. In the crontab.xml<\/strong> file at Vendor\/Extension\/etc<\/strong>, use the below code:<\/p>\n\n\n\n
<?xml version=\"1.0\"?>\n<config xmlns:xsi=\"http:\/\/www.w3.org\/2001\/XMLSchema-instance\"\n        xsi:noNamespaceSchemaLocation=\"urn:magento:module:Magento_Cron:etc\/crontab.xsd\">\n    <group id=\"default\">\n        <job name=\"vendor_extension_cron_job\" instance=\"Vendor\\Extension\\Cron\\CronFile\" method=\"execute\">\n            <config_path>\n                crontab\/default\/jobs\/vendor_extension_cron_job\/schedule\/cron_expr\n            <\/config_path>\n        <\/job>\n    <\/group>\n<\/config><\/pre>\n\n\n\n
4. Use the below code in your php file at Vendor\\Extension\\Cron<\/strong><\/strong><\/p>\n\n\n\n
<?php\n\nnamespace Vendor\\Extension\\Cron;\n\nclass CronFile\n{\n    public function execute()\n    {\n        \/\/ add your custom code as per your requirement\n    }\n}<\/pre>\n\n\n\n
That\u2019s it.<\/p>\n\n\n\n
Also, please share the solution with Magento community via social media.<\/p>\n\n\n\n
