TYPO3自定义扩展注册数据库中的印象

Question

I wrote an extension that picks randomly a defined number of images with link (banners) to display.

I want to count the times they get displayed (impressions). That is, after the random function has made its pick i'd like to increase the database field impressions for the selected entries by one.

This is the pertinent part of the domain repository:

public function findPartnerList($entryNumber = 6) {

    $entries = $this->createQuery()->execute()->count();
    $offset = mt_rand(0, max(0, ($entries - $entryNumber)));

    ... // code refers to a class that picks random

    $result = $query->execute();

   ... // field:impressions should get increased by one for all uid's in $result

    return $results;
}

• I don't know how to handle the object yielded by $query->execute() ...
• I don't know how to write to the database ...
• I don't know how to increase the field impressions by one ...

Answer 1

Basically you should perform manipulations to your domain objects in the controller only and not in the repository - the ORM layer is just the connection between the OOP domain model world and your database.

In WhateverController for instance...

...
/** @var Whatever[] $items */
$items = $this->whateverRepository->findPartnerList();
foreach ($items as $item) {
    $item->setImpressions($item->getImpressions() + 1);
    $this->whateverRepository->update($item);
}
...
