OnLoad - copy field content to a 2nd field

[mliebherr99]

Hello,

how can i copy the (text) content of a entity field into a 2nd field?
This should be triggered when i load the page. (not when saving)

Use Case: I have a primary key (mac address => uniq), if i change the mac address then my hook funktions (afterSave) wont be able to find the uniq mac addres on my 3rd party system.

So i tought i will create a mac_tmp field which i will fill out on loading the page, and when saving it i can search for the old mac and replace it by the new one in my 3rd party system/api.

Thanks,
Michael

Hello,

You can always read the old value of fields from Formula & PHP:

// Formula
entity\attributeFetched('assignedUserId');

https://docs.espocrm.com/administrat...tributefetched

// PHP
$entity->getFetched('mac_address');
