Thank You @distantnative and @walkerbox for guidelines!
But figured out a bit different way - so got it work. My approach:
- Added file “site\fields\action\action.php” (which is copy of panel\app\fields\info\info.php)
- Inside action.php changed result function, now looks like this:
public function result() {
$url = 'http://' . $_SERVER['HTTP_HOST'] . '/mysite/api';
$obj = file_get_contents($url);
file_put_contents('../../api.json', $obj);
}
and in bluprint added:
fields:
action:
label:
type: action
text:
So everytime I something changing in content and push SAVE button afterwards, all content data is saved as JSON.
How to set up JSON export I wrote here: Export all site content as JSON
Why I using such approach with JSON? because I have offline site and don’t want to bother with PHP requests every time. So I have solid data as JSON, but its flexible on every Panel SAVE.
