I'm implementing a hook that is called if certain conditions are met during a cron run.
(Specifically hook_bounce_mails_blocked($mails) from the Bounce module)
The hook is triggered, but any output from dpm() functions is never shown. I do see output from var_dump() after cron finishes.
Is this normal behaviour? Is there a way to get devel output shown once cron finishes?
You should use the function dd() to log something during cron.
Here is the doc: https://api.drupal.org/api/devel/devel.module/function/dd/7
It will log the output to a file, which later you can investigate. I think you must have private file path set.
you could use something like this, But be careful about XSS!
$export = var_export($var, TRUE) // TRUE will cause var_export to return the output not print it.
$export = nl2br($export); // Convert new lines to <br> tag for display in HTML
$export = strreplace(' ', ' '); // Again convert whitespace to HTML specific chatacter
watchdog('my_debug', $export); // That's it!
or even easier: but again be careful about CSSF and XSS
watchdog('my_debug', '<pre>' . var_export($variable) . '</pre>');
dd is the safe drupal way to go.
From comments so you wont miss:
... better than dd() is ddl(), from the drupal_debug_log module that enhances > the devel module... – DrCord
If you search drupal.org modules there are many more to make development easier. After you found and used them, it would sound impossible to go without them (devel_themer to name one). An example search.
