Great replacement for PHx

then - @tpl:chunkname, or any html-code tags MODX
else - @ tpl:chunkname, or any html-code tags MODX
math - consist of a mathematical function in the parameter is
separator - Separator condition in params is

To the parser did not handle option and then and else, as it is in PHx, call: &then=`@TPL:chunkname` - where chunkname - chunk name, then it will be executed only the desired chunk.

The operators used in the condition

is - equal
not - not equal

not_in,!in - the lack of an array

Doing the math functions:

I am new to "IF" and would like to use it instead of "PHX" for well known reasons.

Looking at the info provided I thought I would be able to get this working, but sadly, my attempt(s) haven't worked as expected.

I am currently trying to set a chunk for a set of ID's, when I pre-define one or two it works, but more it doesn't e.g

With two (this works):

With multiple (doesn't work):


Any help is welcome and appreciated.

correct:
[[if? &is=`[*id*]:in:1,2,3,4` &then=`` &else=`@TPL:chunkname`]]

Now thats what I call a speedy reply with an exact solution.

Thanks dmi3y, works a treat

Is this possible?:

if user / usergroup is logged in then x else y?

This is my first time with if snippets.

I am currently trying to use Ditto pagination + If snippet to create a rel="prev" / "next" to avoid duplicated contents with paginate.

My idea: Use ditto placeholder to output links

1) removed [+prev+] [+next] placeholder from my ditto pagination (left only [+pages+])
2) created two chunk for tplPaginatePrevious and tplPaginateNext with only [+url+]

3) added to the head of my template



everything works as expected

Now i need to remove the first line (<link rel="prev" href="[+prev+]" />) only in the first page
and the second line only in the last paginated page.

When ditto paginateAlwaysShowLinks is=0 we dont have next and previous links

So I'm trying



But does not work

Any Help?

Any suggestion?

Dunno if this is any help;

Magento and prolly WP have plugins / extentions for that.

Is this possible with IF?

When I try this it doesn't work, it doesn't show [*background*]

Thanks, but the suggested solution for pagination issue is using rel="next" and rel="prev"
