The question is about the "title". Is "title" metadata of an "object"?

Thanks

Not a metadata but attribute. Anyway, it's works for me but I'm on Elgg 3.

You can use it on Elgg 2:

$query = 'Your unique title';

$options = [
    'type' => 'object',
    'subtype' => 'blog',
    'joins' => ['JOIN ' . elgg_get_config('dbprefix') . 'objects_entity oe ON e.guid = oe.guid'],
    'wheres' => ["(oe.title LIKE '%{$query}%')"],
];

$entities = elgg_get_entities($options);

return $entities[0]->delete;

This works fine.

Only the $entities[0]->delete should be $entities[0]->delete().

Thank you very much, we really appreciate your help.

I don't think a complete solution exists for elgg. You might wanna start looking at another frameworks. WordPress has these complete solutions:

https://wordpress.org/plugins/wp-stripe-checkout/

https://wordpress.org/plugins/woocommerce-gateway-stripe/

For Elgg 2 https://github.com/hypeJunction/Elgg-payments_stripe

I don't know which other plugins you might need. I think this one only provides the API but not the frontend that might be provided by another plugin or plugins. The readme mentions that the development was sponsored by a website. So, I would think there is a working solution available. I would suggest to browse through the repositories of hypeJunction to find out what other plugins you might need and then test them out. But be aware that the original developer does no longer actively works on these plugins. So, it might be necessary to find another developer if you need an update or additional features if you can't do the work yourself.

Thank you rjcalifornia for the search and the suggestion. Yes, the WorPress plugin looks very good but my project is on Elgg with many plugins. I cannot move it to WordPress and I also love Elgg and the community :)

Thank you iionly for the link and the comment. The solution that we need is for the Connect platform of Stripe. It has the ability to split payment, i.e. on a marketplace platform (like eBay) when a user buy an item the money goes in two directions: Main part to the seller and some % to the platform. There is a difference between the standard solution and Connect. However, I assume that most aspects are the same and the above mentioned plugins, with some changes, will be very useful. Anyway, I'm going to try them soon.

Thank you both again. Your help is very much appreciated.

The "Easy method" works fine.

I do not have menu links for this class but calls from an action. And also the class calls other siblings in the original namespace. So I adjusted the "use" calls and it works perfect.

Thank you very much RvR for the useful and detailed answer.

I do not have menu links

It was an example only for understating what you can do ;)

:))

Thank you

You can use elgg_get_metadata with 'metadata_calculation'

see https://github.com/Elgg/Elgg/blob/7804230a2fd21a1c6d411a4166114c8411786e80/engine/lib/metadata.php#L134-L164

Foe some mysterious reason your answer went to the spam.

Thank you Jerome - I'll check it

Sorry,

My problem was with the menu plugin hook. It is called twice.

False alarm :)

I checked with my host. It is a shared plan, which does not support archive.

 It only supports the following DB engines. 

https://stackoverflow.com/questions/1458122/enabling-archive-engine

https://stackoverflow.com/questions/26996618/install-mariadb-archive-engine

Or use the suggested plugin, and delete the system log archives tables manually from your DB.

Don't forget about this.

Made a ticket for this to handle not having ARCHIVE available a bit more friendly https://github.com/Elgg/Elgg/issues/12905
