multiple values for attribute "value" in <txp:if_variable>

With a serious dalay I’m now working on a new site using txp 4.07 and I must say it is really impressive, a great step ahead.
Anyway I have a request, even if I realize it probably will not be taken into consideration for upcoming version 4.08: will it be possible to use multiple values for attribute “value” in <txp:if_variable>? I would find it very useful.

P.S. thanks again to all developers for their great work

Re: multiple values for attribute "value" in <txp:if_variable>

A list of values would have to be separated by a special character, presumably a comma, which would then have to be excluded (or escaped) from the individual values.

E.g.:

<txp:if_variable name="foo" value="apple,pear,orange">

tests for either “apple”, “pear”, or “orange”, while

<txp:if_variable name="foo" value="oh\,my,dear,darling">

tests for either “oh,my”, “dear”, or “darling”

Is this a feasible solution?

Re: multiple values for attribute "value" in <txp:if_variable>

Wet you’re right, I hadn’t thought about this.
I like your solution, maybe another one could be to wrap in “’” the values containing a comma, like this:

<txp:if_variable name="foo" value="'oh,my',dear,darling">

anyway I’d be happy with both solutions. Thank you!

Re: multiple values for attribute "value" in <txp:if_variable>

I’d limit functionality to a simple comma separated list, similar to all other TXP tags that allow comma separated values:

<txp:if_variable name="foo" value="apple,pear,orange">

Yes ruud, this was my initial request, but then there is the problem outlined by wet (if txp:variable has a value which contains a comma).

Re: multiple values for attribute "value" in <txp:if_variable>

I suspect in most cases one could use different values instead to avoid that problem. Introducing a new escaping method for this purpose is not worth it. Tag functionality is always limited in some way, so this would be a limitation of this particular tag, IMHO. Keep it simple!

Re: multiple values for attribute "value" in <txp:if_variable>

Mmm… yes, from my point of view your solution is ok too.
And actually I have no idea how many people are using the <txp:if_variable> and <txp:variable> tags in ‘creative’ ways, so probably you are right when you say it’s not worth the effort.
Well… I realize I can’t add nothing particularly brilliant to the discussion now so I’ll stop talking.
Thank you again

Re: multiple values for attribute "value" in <txp:if_variable>

You could always add a second attribute, say values?

Re: multiple values for attribute "value" in <txp:if_variable>

Did this make it into v4.2?

If not, can you do an Indiana Jones and reach back and grab your hat (tag) before the stone rolls shut ;-) ?

(found wet’s suggestion most consistent with other tags)

Re: multiple values for attribute "value" in <txp:if_variable>

I found this old thread by chance and now I’m wondering if there is a slight possibility this will be included in txp 4.3 (yes I know it’s late).
I can’t have a look at the code but maybe something could be borrowed from the recent changes in “if_custom_field” tag?

What’s the current way to do this? Is there any native way? Is smd_if the only option? Is there some other method?

Thank you!

Re: multiple values for attribute "value" in <txp:if_variable>

If you don’t need to test against too many values, you can nest the if_variable tags:

<txp:if_variable name="foo" value="apple">
   OK
<txp:else />
   <txp:if_variable name="foo" value="orange">
      OK
   <txp:else />
      <txp:if_variable name="foo" value="pear">
         OK
      <txp:else />
         Not OK
      </txp:if_variable>
   </txp:if_variable>
</txp:if_variable>
