Hidden extrafields of type boolean are set to 0 on update

[glu000]

Bug

Hidden extrafields of type boolean are set to 0 on update. Can only happen with extrafields in positions of commercial elements (facture, propal, commande, etc)

Dolibarr Version

18, 19, develop

Environment PHP

na

Environment Database

na

Steps to reproduce the behavior and expected behavior

1. Create an extrafield of type boolean for an invoice or proposal or order on the lines (DB: ....det_extrafields) and set visibility to 1
2. Create a new line (position) of an element where you have created the extrafield and enable the checkbox
3. Set the visibility of the extrafield created in step 1 to 0
4. Edit the line which has been created in step 2. Doesn't matter what is changed, just important to push the "save" button
5. Set the visibility of the extrafield created in step 1 to 1
6. View the line created in step 2 - Checkbox is not set (value 0)

The value is now back to null even though we never actually changed the value, only the definition and the visibility.

[JonBendtsen]

Looking in the database llx_propaldet_extrafields

the rowid number changes every time the propal line is edited, and during this process the glu000 value gets reset to NULL - my guess is that it inserts a new line in the database.

[JonBendtsen]

@glu000 I think the code here is why that value disappears when you hide and unhide it.

https://github.com/Dolibarr/dolibarr/blob/develop/htdocs/core/class/extrafields.class.php#L819-L888

[JonBendtsen]

@eldy is there some technical reason for why the extrafield is first deleted from the database and then created again?

Why not just use UPDATE?

@eldy is there some technical reason for why the extrafield is first deleted from the database and then created again?

Why not just use UPDATE?

Historical reason.
Sometimes the line into the extrafields does not exists at all, so we can't update, we must insert. The delete/insert was an easy way to do this without getting the error when doing insert if line already exists. And the update method did not exists.
A bad practice that must be removed.
There is now no reason to continue to do delete/insert because the update method should now exists i think (not sure).
