How to get previous attribute value in beforeSave or afterSave Hook

[czcpf]

Hello,

In a custom Hook, how would one get the previous attribute value in afterSave and/or beforeSave hook?

Example:

Let's say in UI someone changes the entity field 'myattribute' from 4 to 5 and hits save.

What I would like to achieve,

Using beforeSave and/or afterSave I would like to know if 'myattribute' has changed, what was the previous value of it and what is the new value of it.



MyCustomHook

public function afterSave(Entity $entity, array $options): void
{

if( $entity->isAttributeChanged('myattribute') ) {
//get previous attribute ?
//$entity->getPreviousAttribute('myattribute);

}

}​

Hi,
check on github. "fetched"

Thanks. So getFetched is doing what exactly? Is that the parameter value after saving to db or before saving to db or what?

Thanks item for pointing me in the right direction. I just tested the custom hook and it worked as expected. Below is a code snippet to get the old and new fileId attribute in a afterSave hook.

public function afterSave(Entity $entity, array $options): void {

    if( $entity->isAttributeChanged('fileId') ) {

        $currentFileId = $entity->get('fileId');
        $previousFileId = $entity->getFetched('fileId');

        $GLOBALS['log']->warning('MyCustomHook.php Espo\Custom\Hooks\Document ',
           ['currentFileId'=>$currentFileId,'previousFileId'=>$previousFileId]);

    }

}​
