elseif or switch statements hack with phx

To emulate the elseif functionality we have to use the PHx or statement and a few PHx if statements.

Hopefully the code says it all:

[+phx:if=`[*id*]`:is=`1`:or:is=`2`:then=`
    [+phx:if=`[*id*]`:eq=`1`:then=`
        {{Chunk-1}}
    `:else=``+]
    [+phx:if=`[*id*]`:eq=`2`:then=`
        {{Chunk-2}}
    `:else=``+]
`:else=`
    {{OtherChunk}}
`+]

The above code can also be used for switch statements like functionality.

If you use this to check some value, that if changed the cache is not cleared, the page should not be cacheable. I mostly use this to check resource IDs or template IDs so the page can always be cached.

In most circumstances for this to work properly, page should be un-cached.

True,
I mostly use this with resource ids or template ids. In these cases that page can be cached.

I'll add a note

Very interesting! Thanks
Anyhow else statement is not working herw with revo 2.1.3

Trie a simple example:
1.
⌈⌈+phx:if=`this`:is=`this`:or:is=`that`:then=`YES`:else=`NO`+⌋⌋
OUT: YES (correct)

2.
⌈⌈+phx:if=`that`:is=`this`:or:is=`that`:then=`YES`:else=`NO`+⌋⌋
OUT: YES (correct)

3.
⌈⌈+phx:if=`foo`:is=`this`:or:is=`that`:then=`YES`:else=`NO`+⌋⌋
OUT: none!! (wrong expected NO)

Any help?
Thanks

This for MODX Evolution not MODX Revolution. You might be able to use IF for MODX Revolution.
