Cron Job |
|
Cron Helper used to run any job in a particular time. We have two steps to setup this scheduler process.
Step 1: In first steps we create Scheduler Functions in helper file.
Step 2: In second step we add Cron File in a any scheduler.
Cron File:
There is a Cron file in Webroot folder that we have to add it in any scheduler like Schedule Job, Cron Tab or CLI to execute in a particular time. See below file location:
webroot/cron.php
This file can execute both in URL or Directory path mode.
Below is the helper location to write all jobs :
/development/helper/cronjob.php
A function is considered as a schedule job if we add a keyword "Job" as a post fix. See below example.
protected function testfxJob()
{
// Do operation
}
System always read the schedule time from the comments of a function. We write the comments like below
@schedule [07:00-8:00 12:00-13:00 18:00-20:30]
According to the above format the schedule function runs if Cron File run between 07:00 or 8:00 and 12.00 and 13.00
Also we can create like @schedule [*] then function will run each time Cron File execute.
See below example:
class Development_Helper_Cronjob extends appRain_Base_Modules_Cronjob
{
/**
* An Example funcntion
* on each time Cron Job run
*
* @schedule [*]
*/
protected function testFx1Job()
{
}
}
Lets see an example to send an email in a particular period.
Step 1: First Create below method in
/development/helper/cronjob.php
class Development_Helper_Cronjob extends appRain_Base_Modules_Cronjob
{
/**
* An Example funcntion
* on each time Cron Job run
*
* @schedule [*]
*/
protected function sendMyMailJob()
{
App::Utility()->Mailing('jhon@example.com','info@example.com','Cron Notification','This is a test Cron email');
echo "Mail event execute successfully.";
}
}
Step 2: Now add below file in a Cron Tab or Scheduler job. You can execute it both in URL or CLI on Directory path.
For a simple test browse www.example.com/cron.php.
