Apply password policies to account password elements on custom forms

If it is possible to detect account password elements on a form, and call password_policy_password_element_alter() for them, I think that would be preferable to adding a hook. This solution requires other modules to know about Password Policy (i.e., add Password Policy integration code). Ideally, Password Policy would not need to know about other modules, and other modules wouldn't need to know about Password Policy.

Looks nice, except why the altering removed in last patch?

Patch #4 works nice on custom forms.

Much cleaner and more reliable, there isn't any need for an alter now.

7.x-1.x hardcodes form IDs but I think it would be better not to make this change in that branch until it has been tested for a while through use.

Hello, first of all, thank you for the patch.
I am using it on top of 7.x-1.x-dev and I had to make some changes in order to use password policies in a custom form with fieldsets. Basically, what I am doing is getting the password elements from the form based only on their type, regardless of their name or their position on the form structure (inside a fieldset or not). Feel free to contact me if you have any questions about my changes.

New version fixing some details to get even more custom forms.

New version if the custom form uses container instead of fieldset.

I have found another scenario that requires adjustments. When you are using a custom registration form, the policy is not loaded correctly, because the code is only checking for the specific form_id user_register_form. I've adjusted to check for the anonymous role. If the user is not logged in, he is trying to register (it is a registration form).

Please find attached the new patch containing this change.

@Oleksiy Nice idea +1

Took a quick look at #15. It seems like it finds all elements of type 'password_confirm'? Problem is a 'password_confirm' is not necessarily used for an account password. It's just a Form API control type that you can use for any sort of password requiring confirmation. That is, not all 'password_confirm' elements are necessarily for account passwords. Please correct me if wrong.

Commit in #9 ensures they are account password elements by requiring the presence of the 'account' array key.

Ported #4 to 7.x-1.x.

This should apply password policies to account password elements on custom forms.

Fixed Password Change Tab submodule to work with changes from #19.

Moved function to different section of file for consistency.

Now implemented in 7.x-1.x and 7.x-2.x.

Thanks everyone for their work on this issue.

Given #2924009: Apply password policies to password elements on custom forms is working on the D8+ version, closing this as fixed for Drupal 7.

And closing.
