Hello FS Community

I have an FS_CATALOG component, which uses 2 link templates:

      <FS_CATALOG name="st_links" viewMode="headers">
        <LANGINFOS>
          <LANGINFO lang="*" label="Link"/>
        </LANGINFOS>
        <TEMPLATES type="link">
          <TEMPLATE uid="lt_internal_external"/>
          <TEMPLATE uid="lt_cta_btn"/>
        </TEMPLATES>
      </FS_CATALOG>

I want to write a rule with following logic:
IF editor selects lt_internal_external

     MAXIMUM 3 Entries

ELSEIF editor selects lt_internal_external as first and lt_cta_btn as second

     MAXIMUM 3 Entries

ELSE editor selects lt_cta_btn first as first

     MAXIMUM 1 Entry

I have written a rule that limits to maximum of 3 entries, and when we have 3 entries no new entries are allowed.

Current rule:

<!-- ### st_links max 3 entries -->
<RULE>
<WITH>
<LESS_THAN>
<PROPERTY name="SIZE" source="st_links"/>
<NUMBER>3</NUMBER>
</LESS_THAN>
</WITH>
<DO>
<VALIDATION scope="INFO">
<PROPERTY name="VALID" source="st_links"/>
<MESSAGE lang="*" text="Maximal 3 Einträge erlaubt!"/>
</VALIDATION>
<PROPERTY name="NEW" source="st_links"/>
</DO>
</RULE>

Is this even possible within FirstSpirit Rule syntax ?

My regards

Aleksandar

Hi Aleksandar,

It's a bit difficult, but you could achieve a somewhat similar logic by using the CONTAINS expression with FS_CATALOG, which checks for used templates.

The logic you could realize would be:

• Have at most 3 entries
• If the component contains an lt_cta_btn based entry only, limit to one

I have not tried it, but this should be doable.

You will find the documentation to CONTAINS online at: Online Dokumentation FirstSpirit - <CONTAINS/> Inhaltsprüfung

Hope this helps.

Cheers

Stefan
