How do we set character limits for the Display Name Field and the Nickname fields?  

Hi @crisw,

I've just asked our developers about it and currently, I'm waiting for the response from them. I'll update the topic one I get some response from them.

Hi @crisw,

Hi @alvina,  Thanks for responding and getting your developers to look into this. In the meantime, I have temporarily used the code below to hide the "Display Name" from the Account Profile.  I thought I would share it here, in case others might want to use it too.  

I was able to tweak the WP Core user file, so our WP site now has only 12 character limits for the Username (which on the forum, gets duplicated into the "Display Name" and the "Nickname" fields by default). 

The issue I see in the form at the Member's Account Profile, on the "Display Name" text field, it seems to not have a maxlength character limit on the field itself, so if anyone inputs extremely long Display Name, it will break the forum layout ("Profile", "Post" Box, and the "Likes"  as shown in above screenshot). 

So in the mean time, I put the codes below (Forum Settings > Styles > Custom CSS) 

/*Do not display Display Name Label & Text Field - PROFILE PAGE*/
div.wpf-field.wpf-field-type-text.wpf-field-name-display_name.wpf-field-required {
display: none;
}

And since the Nickname field also has a maxlength of 50 characters, it also protrudes through the comment box, and does not look good so, I also added this code below: 

/*Automatically adjust long Nicenames or Nicknames to responsively fit smaller screens - COMMENT BOX*/

div.wpf-author-nicename {
white-space: wrap !important;
max-width: 90% !important;
width: 90% !important;
overflow: hidden;
text-overflow: ellipsis;
word-wrap: break-word;
}

I hope that the Developers can look into the max-length of the field names for "Display Name" and "Nickname".  

Thanks!  God bless you! 🙂
