1- In your AdminCP, select User Profile Fields >> Add New User Profile Field. Choose “Single Selection Radio Buttons” as the profile field type and hit “Continue”

2- Use these values in the following fields:

User Profile Field
Title: Display Subforums?
Description: Changing this option will show/hide the subforums on the main page.
Options: Yes, No (each option is on a different line!)
Set Default: Yes
Field Required: No
Field Editable By User: Yes
Private Field: Yes
Field Searchable on Members List: No
Show on Members List: No

Optional Input
Allow user to input their own value for this option: No

Display Page
Which page displays this option: Options: Thread Viewing

3- Hit “Save”, and you’ll be taken to the User Profile Field Manager. Take note of what the field ID for your new option is… In my case, it’s “field7”

4- Go to Styles & Templates >> Style Manager and choose “Edit Templates” on whatever forum style you want this to apply to.

5- In the Style Manager for your template, choose PHP Include Code Templates >> phpinclude_start

6- At the very top of your template, paste the following code:

PHP Code:

if ($bbuserinfo['field7'] == 'No')
{
$vboptions['subforumdepth'] = 0;
} 


Note that ‘field7’ needs to be replaced with whatever number your new User Profile Field Option is!

7- Click save, and you’re done!

============================================

This template modification assumes that your subforum depth is set to 1 by default. If your subforums are set to 0, do the following:

1- Instead of:

Yes
No

in your User Profile Field Options, make it:

No
Yes

2- Use this bit of code in your phpinclude_start template instead of the one used above:

PHP Code:

if ($bbuserinfo['field7'] == 'Yes')
{
$vboptions['subforumdepth'] = 1;
} 


Remember to replace ‘field7’ with whatever yours is!
