Field viewable only by X usergroups.

[Lautaro]

Hello,

I'm working on a modification and I've added a panel to edit a few options of it on the vBulletin Options.

Now, I have added the next on my product XML:

        <phrasetype name="vBulletin Settings" fieldname="vbsettings">
            <phrase name="setting_vbducpoptstitle_desc" date="0" username="VBDMPP" version="1.0"><![CDATA[description of the option here]]></phrase>
            <phrase name="setting_vbducpoptstitle_title" date="0" username="VBDMPP" version="1.0"><![CDATA[Title of the option here]]></phrase>
            <phrase name="settinggroup_vbdgroup" date="0" username="VBDMPP" version="1.0"><![CDATA[main title here]]></phrase>
        </phrasetype>
    <options>
        <settinggroup name="vbdgroup" displayorder="1000">
            <setting varname="vbducpoptstitle" displayorder="10">
                <datatype>text</datatype>
                <defaultvalue>0</defaultvalue>
            </setting>
        </settinggroup>
    </options>

On that field I will write the usergroups allowed to see X content.
then add another field like that but with the id's of the users excluded from viewing that content.

What i need is the PHP condition for this. I have done another condition for a field where you have to select yes or no, but what I want here is a condition so the usergroups ID i write there ( separated by comas ) have access to view X content on a template.

Thanks !
