The upgrade script (php tools/upgrade.php upgrade) created an entry for my plugin, in the versions table but any call to the hook still returns a blank page.
The plugin code is as follows:
class ZohoMailerPlugin extends GenericPlugin {
function register($category, $path) {
if (parent::register($category, $path)) {
if ($this->getEnabled()) {
HookRegistry::register('Mail::send', array(&$this, 'callback') );
$hooks = HookRegistry::getHooks();
var_dump($hooks);
}
return true;
}
return false;
}
function callback($hookName, $args) {
// just to see if this gets called
echo "caught";
}
I suspect your plugin isn’t properly registered with the system. Is there a mismatch between the plugin’s information and the stuff in the version.xml descriptor? (This would be reflected in the versions table after running the update script.)

The contents of the <application> element should match the last part of the pathname that the plugin is in, and the <class> element should match the name of the plugin class. If you have to correct one of these, also correct it in the versions table.

This was mismatched, I corrected it and the versions table, but I still get a blank page. I ran the upgrade script again, still blank page, still a really long load time.
That looks OK to me – can you re-check a few of your previous avenues, like making sure the plugin is enabled, checking the error log, etc.? I’m also a little concerned about the blank page – can you try linting the PHP files in your plugin (php -l /path/to/php-file)?
Also, just in case, flush the .php files in the cache/ subdirectory.

No errors were found in the php files, however when I changed the config to turn off smtp, I no longer get a blank page but it still skips right over my callback.
So then I cleared out the cache, emptied my php error log, dropped all the tables, set config installed=Off. Then I re-installed OJS via the web interface, re-created my demo journal, enabled the plugin and ran the upgrade script, went to email form and clicked send. Again it skipped right over my callback, which I have now edited to throw a fatal error if it ever gets called, but it does not.
Here is a link to the entire php error log after the above steps:
Further attempts to trigger the callback have added nothing to the log.
