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

redbot · 2009-01-22 13:48:16

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

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?

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!

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).

ruud · 2009-01-22 19:20:38

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!

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

You could always add a second attribute, say values?

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)

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!

[Edit: Fix bq formating.]

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>
