and after that i want if month=2005-04 and page=2 then show 3 articles.

Then you’ll need something like:

<txp:smd_if field="urlvar:month, urlvar:pg" operator="eq,undefined" value="2005-04">
 // Show one article here
<txp:else />
  // Show 3 articles here
</txp:smd_if>

EDIT: but also remember that the ‘else’ will be executed if the month variable is something other than 2005-04

OK, this is interesting….

I routinely use mdp_calendar to build cals on installs…

One of the problems I have is that a link from a small calendar will lead to a date based url. I have not found a way to gracefully distinguish between a single article and an article list (one event that day or two.) So that if it’s a single article it displays <txp:body/> and if it’s a list display <txp:excerpt/>.

The best I’ve come up with is to always display the first article in full and thereafter as excerpts.

Any other Text-Fu? Come on chumpus, go purple.

oke,

If i understand it right :

if month=“2004-05” and pg is not defined or pg=1

i do this :

<txp:smd_if field=“urlvar:month, urlvar:pg, urlvar:pg” operator=“eq,undefined,eq” logic=“and”,“or” value=“2005-04”,“1”>

Nope. You can only do one type of logic at a time, sorry. You have to choose either AND (the default) or logic="or" to switch it. I did consider allowing multiple logic types (see an earlier post by the_ghost) but it was very complicated and I abandoned the idea. Especially since nested smd_if calls are going to be allowed in TXP 4.0.7.

Under TXP 4.0.6, what you are trying to do is pretty tricky and I can’t think of a way of doing it without resorting to some <txp:php> inside the <txp:smd_if> tag.

Interesting indeed, but bad news for you as well: I can’t find a variable anywhere on the page that would allow me to test that condition. If it ain’t on the page, I can’t check it :-(

I wondered if $thispage had anything useful (like, if the calendar used it to store the total number of results that matched the current date) but for some reason I can’t even display the contents of it on my SVN test site; I just get back NULL all the time. Clearly I don’t understand what it does, despite trying this! I’ll delve a bit deeper, but at the moment it’s no no mojo from the chumpstick right now.

Hello Bloke,

Thank you for your time.
If this is not possible it no big deal.

(Stef, sorry for abusing your plugin thread, but) Roelof, if all you need to do is check if it’s the first page or not, wouldn’t wet_if_page be a better and simpler way to do that?

roelof · 2008-11-16 11:40:08

Hello Els,

I have to check if the month is 2005-04 and if it’s then i have to check if it’s the first page of that month.

Bloke · 2008-11-16 11:50:47

Els is right (thank you). You can do what you ask, like this:

<txp:smd_if field="urlvar:month, urlvar:pg" operator="eq,undefined" value="2005-04">
  // Show one article here
<txp:else />
  <txp:wet_if_page page="1">
    // Show one article here also
  <txp:else />
    // Show 3 articles here
  </txp:wet_if_page>
</txp:smd_if>

i.e. if the month is 2005-04 and the pg is not used, you must be on the front page, thus you show one article. If, however, the page is used you enter the ‘else’ block whereby it checks to see if the page is page nmuber 1. If it is, you only show one article, if it’s not you show 3.

Thanks again Els. Nice one!

Hai Bloke,

Your script works only i have 3 remarks.

1) The other months shows now the first article double.

2) Ob-pagination thinks on the first page that there are 5 pages and on the second page there are two pages.

3) The month 2005-04 has 7 articles nl. 1,4,5,7,11,15,24 april When using this script on page 1 i see 1 april , that’s correct. But on page 2 i see 7 and 15 april. The rest of the articles seem tot be disappear.

You can see it work at : http://test2.tamarawobben.nl

Regards,

Roelof

Hello,

Can 4.0.7 with nested tags and adi_gps together with this plugin be a solution ?
If so, it is difficult to use svn for a live website ?

Yes, very much so. Adi’s my hero today :-)

Under 4.0.7 you could do it without Adi’s plugin because you can nest the smd_if calls and make up complex layers of conditionals that successively filter your data until you reach the desired action. But using adi_gps means you can take advantage of the decode option (if necessary). If you do use adi_gps you can also rename the variables if you wish and use smd_if to get at them like this: field="txpvar:my_renamed_variable". It may not be necessary in this case but it’s certainly a nice feature to make your smd_if calls a little tidier!

If so, it is difficult to use svn for a live website ?

It’s not recommended simply because the kinks have not been ironed out. But Stuart does (and has been for ages) and he’s only found one problem with searches recently, which will be fixed soon.

If it is for a paying client I would steer clear of SVN but if it’s your own site, you might as well try it. Just make sure you backup your database and the files in your install first so it’s easier to roll back if you have to :-)

roelof · 2008-11-18 12:54:39

oke,

Now the problem that ob-pagination displaying the wrong numbers of pages.
Maybe i can use then <txp:variable> but i don’t know how to use then the value in a php script as ob-pagination is.

Blimey … you’re very kind.

Reason for the call is that I’ve made a Feature idea suggestion txp:variable increment & decrement and if it gets wings then how about an enhancement to smd_if to add a new operator “is divisible by” which would test whether a supplied number is divisible by a given divisor.

For example, this would help if you wanted to do zebra stripes (divisible by 2: i.e. even or odd).

And implementing a matrix/grid/table would be easier as well (e.g. if count is divisible by row length, then do something different).

Or maybe it should be some sort of modulo operation (i.e. remainder of zero = “is divisible by”)?

Hoi Bloke,

this plugin is not working properly with 4.0.7.

I have this page template :
<txp:smd_if field=“urlvar:month, urlvar:pg” operator=“eq,undefined” value=“2005-04”> <txp:article limit=“1” form=“dagboek” sort=“Posted asc” /> <txp:ob1_pagination outputlastfirst =“0” outputnextprevious=“0” />
<txp:else /> <txp:smd_if field=“urlvar:month, urlvar:pg” operator=“eq,eq” value=“2005-04”,“1”> <txp:article limit=“1” form=“dagboek” sort=“Posted asc” /> <txp:ob1_pagination outputlastfirst =“0” outputnextprevious=“0” /> <txp:else /> <txp:smd_if field=“urlvar:month, urlvar:pg” operator=“eq,eq” value=“2005-04”,“2”> <txp:article limit=“3” form=“dagboek” sort=“Posted asc” /> <txp:ob1_pagination outputlastfirst =“0” outputnextprevious=“0” />
</txp:smd_if>
</txp:smd_if>
</txp:smd_if>

It’s showing the articles fout times.

Here’s the tag trace:
