Execute cron jobs on the server

[oli03]

Hello,

I can't make the cron jobs working.
I've read the documentation here : https://docs.contao.org/books/cookbo...in-Contao.html

What I've done :
1. unchecked in the system configuration page the checkbox so the cron.php can be executed by a real cron job
2. create on my server a cron job like that : * * * * * wget -O /dev/null -q http://example.com/system/cron/cron.php
3. in the config.php file of my extension; I've added the classe :
$GLOBALS['TL_CRON'] = array
(
'monthly' => array(),
'weekly' => array(),
'daily' => array(),
'hourly' => array(),
'minutely' => array( array('STBRappels', 'envoyerRappels'))
);

That doesn't work. I only receive a mail from my server so I know that the cron job is fired.

But if I execute cron.php manually (as explained in the doc), it works.

Thanks a lot for your help.

3. in the config.php file of my extension; I've added the classe :

  $GLOBALS['TL_CRON'] = array
  (
     'monthly' => array(),
     'weekly'   => array(),
     'daily'    => array(),
     'hourly'   => array(),
     'minutely' => array( array('STBRappels', 'envoyerRappels'))
  ); 

Regardless of your actual problem: you should not do it this way. Because this way you delete all other cronjobs of Contao. Instead, do this:

$GLOBALS['TL_CRON']['minutely'][] = array('STBRappels', 'envoyerRappels'); 

Can you log in via SSH to your server and execute

wget -O /dev/null -q http://example.com/system/cron/cron.php

manually from there?

Thank you for your answer.
You're right, thank you for this correction.

I don't understand why we have to choose between 'monthly','weekly','daily','hourly','minutely' in the config file as we decide the frequency on the server.

EDIT
Ok, it works. I now receive an email every minute.
I will try every hour ou every day.

That's not how it works. You decide via $GLOBALS['TL_CRON']['…'] how often a specific job should be executed, regardless of how often cron.php is actually called. There are certain jobs in the Contao core which are only executed once every month for instance. However the cron.php itself might be called minutely or even secondly.

By doing

$GLOBALS['TL_CRON']['minutely'][] = array('STBRappels', 'envoyerRappels'); 

you are essentialy defining that this job is executed at most once every minute, but not more often than that (even if the cron.php is called more often than that).
