I am trying to update an entry's title in a Craft 3 module after an entry is saved. I cannot use EVENT_BEFORE_SAVE_ELEMENT because the title gets updated after this. If I use EVENT_AFTER_SAVE_ELEMENT to update the title and then do saveElement the event gets called again and I get into an infinite loop.

Event::on(Elements::class, Elements::EVENT_AFTER_SAVE_ELEMENT, function(Event $event) {
    if ($event->element instanceof \craft\elements\Entry) {
        if ($element->section->id == 1 && $element->typeId == 1) {
            $element = $event->element;
            $newTitle = "new title"; // logic goes here
            $element->title = $newTitle;
            Craft::$app->elements->saveElement($element); // causes loop
        }
    }
});

Is there a way to do this? Thanks.

  • Yes how do you do this? Seems a lack of documentation or examples for events and plugins

I got this working by using the EVENT_BEFORE_SAVE_ELEMENT and adding the asset to the entry asset field 'pdfThumbnailImage' by using the setFieldValue.

 $entry->setFieldValue('pdfThumbnailImage', [$assetId]);

You dont need to save the element - leave this out

 Craft::$app->elements->saveElement($element); // causes loop

  • Thank you, but this doesn't work for the title field. Custom fields can be updated like this using EVENT_BEFORE_SAVE_ELEMENT, but the title gets changed again after this.

  • Are you using setFieldValue('title') ? What about something like : if(isset($fields['title'])) { $entry->title = $fields['title']; unset($fields['title']); } if(isset($fields['slug'])) { $entry->slug = $fields['slug']; unset($fields['slug']); } $entry->setFieldValues($fields); via -> craftcms.stackexchange.com/questions/20962/…

  • $element->setFieldValue('title') is an Unknown Property, and setting $element->title doesn't work as it gets overwritten after the event.

  • Just tested in my plugin : $entry->title = "Fooobar"; worked fine when saving in the CP. That's without Craft::$app->elements->saveElement($element); Maybe check you are not saving the element and use the event EVENT_BEFORE_SAVE_ELEMENT. Just setting the title $entry->title = 'whatever'

  • Ah, it wasn't working for me because I had Show the Title field disabled with a temporary name in the Title Format field. That was overwriting my code. When I turn Show the Title field back on the $entry->title = "Fooobar" works. Thank you so much for your help. :)
