Re: smd_if: Generic multiple if condition tests

My first-time use of smd_if :) As always: great plugin, thanks Stef! I need to add a class to the html body tag, depending on the season. I’ve managed to do it like this:

<txp:variable name="thisMonth" value='<txp:php>echo strftime("%m");</txp:php>' />
<txp:variable name="thisDay" value='<txp:php>echo strftime("%e");</txp:php>' />

<txp:smd_if field="txpvar:thisMonth, txpvar:thisMonth" operator="eq, eq" logic="or" value="01, 02">winter</txp:smd_if>
<txp:smd_if field="txpvar:thisMonth" operator="eq" value="03">
	<txp:smd_if field="txpvar:thisDay" operator="le" value="21">winter<txp:else />spring</txp:smd_if>
</txp:smd_if>
<txp:smd_if field="txpvar:thisMonth, txpvar:thisMonth" operator="eq, eq" logic="or" value="04, 05">spring</txp:smd_if>
<txp:smd_if field="txpvar:thisMonth" operator="eq" value="06">
	<txp:smd_if field="txpvar:thisDay" operator="le" value="21">spring<txp:else />summer</txp:smd_if>
</txp:smd_if>
<txp:smd_if field="txpvar:thisMonth, txpvar:thisMonth" operator="eq, eq" logic="or" value="07, 08">summer</txp:smd_if>
<txp:smd_if field="txpvar:thisMonth" operator="eq" value="09">
	<txp:smd_if field="txpvar:thisDay" operator="le" value="21">summer<txp:else />autumn</txp:smd_if>
</txp:smd_if>
<txp:smd_if field="txpvar:thisMonth, txpvar:thisMonth" operator="eq, eq" logic="or" value="10, 11">autumn</txp:smd_if>
<txp:smd_if field="txpvar:thisMonth" operator="eq" value="12">
	<txp:smd_if field="txpvar:thisDay" operator="le" value="21">autumn<txp:else />winter</txp:smd_if>
</txp:smd_if>

but it’s such a lot of code… I’ve tried using REQUEST_TIME, but I can’t figure it out. (Of course the plugin is not to blame, it’s just my limited knowledge…) This code is obviously wrong:

<txp:smd_if field="svrvar:REQUEST_TIME, svrvar:REQUEST_TIME" operator="eg, lt" value="2009-06-21T00, 2009-09-21T00">
	summer
<txp:else />
	<txp:smd_if field="svrvar:REQUEST_TIME, svrvar:REQUEST_TIME" operator="eg, lt" value="2009-09-21T00, 2009-12-21T00">
		autumn
	<txp:else />
		<txp:smd_if field="svrvar:REQUEST_TIME, svrvar:REQUEST_TIME" operator="eg, lt" value="2009-12-21T00, 2010-03-21T00">
			winter
		<txp:else />
			spring
		</txp:smd_if>
	</txp:smd_if>
</txp:smd_if>

All conditions return false, and I think I can see why: $_SERVER["REQUEST_TIME"] is returning something like 1250452878, so of course it will never match something like 2009-09-21T00

So I’m asking myself – well actually I’m asking anyone but myself of course ;)

  1. How (if at all) can I get this to work, using either another format or maybe another variable?
  2. If I can get this to work, is it possible to make it year-independent, so I don’t have to remember to change the values every year?

As I said I’ve already got it working using the txp variables, besides I’m aware that my questions are not exactly related to the plugin, so please don’t feel obliged to answer them.

Re: smd_if: Generic multiple if condition tests

<txp:php>
  $seasons = array('1221' => 'winter', '0921' => 'autumn', '0621' => 'summer', '0321' => 'spring', '0000' => 'winter');
  foreach($seasons as $date => $season) if (strftime('%m%e') >= $date) break;
  echo $season;
</txp:php>

Re: smd_if: Generic multiple if condition tests

Perfect! Thanks again :)

Sorry Stef, no need for the plugin after all…

Hehe, no worries. You can’t resist its charms forever ;-)

If you do ever get into this multi-condition scenario again and ruud isn’t at hand with an awesome bit of PHP to save the day, you could try smd_multi_choice which — if used cunningly — might have made the smd_if spaghetti slightly more manageable.

Re: smd_if: Generic multiple if condition tests

ruuds piece of code is a great example for a textpattern solution via code snippet.

Where do we store such TXP snippets?

I know the day will come where I want to publish all my winter activity recommendations in one article :)

Edit: For myself I found a pretty good solution for a structured repository lately: Zotero. I added an entry in my public Zotero group / Markus Merz / Textpattern (Detail).

Pls. have a look. If you want you may join ‘my’ group or we could create a public group ‘Textpattern’ (just to clutter the TXP environment a little more :)

Re: smd_if: Generic multiple if condition tests

Btw, you may want to use safe_strftime instead of strftime to make it work properly in your timezone, unless it doesn’t really matter much if a season starts a few hours early or late.

Either I completely forgot about that, or I completely overlooked it… Looks sweet, I’ll keep it in mind for a next case!

It doesn’t really matter in this particular case, but I’ll change it to safe_strftime anyway, thanks.

I will. At the moment I’m storing useful snippets, files etcetera about anywhere on my computer, without much structure…

[OT] At the moment I’m storing useful snippets, files etcetera about anywhere on my computer, without much structure…

That’s the good thing about Zotero. You store ‘etc.’ on your computer, add some metadata whenever you like and you may also publish the dataset to an open zotero group or not. Do you have webDAV server space? Yes, well, then add documents and have them synced with the webDAV server. Nice!

Re: smd_if: Generic multiple if condition tests

Stef,

I think I’m going mad. The following:

	<txp:variable name="count" value="6" />
	<txp:smd_if field="txpvar:count" operator="divisible" value="3">
		<txp:variable name="count"/> is divisible by 3
	<txp:else />
		<txp:variable name="count"/> is not divisible by 3
	</txp:smd_if>

gives me:

6 is not divisible by 3

What am I missing?

Cheers,

Adi
