[SOLVED] Add field in project - planningelement

Good morning,

I must add a field on the main screen "project' with a simple rule.
This field should be link to "priority'

1 - alter table : planningelement with a varchar mynewfield
2- modify lang.js (column & idcolumn)
3 - modify planningelement.php
3a - declare mynewfield
3b- add a specific rule (need to be done) case... priority -->change value of mynewfield

I can validate my project
But I loose a part of the functionality of filters & all select column.

So I need advices
Edit I still need advices but finally everything is fine now.

Regards,
Fabien

Good morning

I do not know if this is the right method.
And now I realise a screen for adding project elements and I look for a method.

I 'm not a programmer but a portfolio project manager so I'm not sure if I do it the correct way.

Do you have descriptions of methods ?
