smd_if: Generic multiple if condition tests

If what jakob suggests isn’t what you’re intending, you might have more luck with this syntax for smd_if:

<txp:smd_if
   field="txpvar:section"
   operator="notin"
   value="brunes/blondes/ambres/noires/speciales">
//show anything
</txp:smd_if>

Each time you were using the comma it was comparing the individual items in your list against the field but using the not operator for the first comparison only. Thereafter it used the default operator, eq. So your statement was equivalent to this:

<txp:smd_if
   field="txpvar:section"
   operator="not,eq,eq,eq,eq"
   value="brunes, blondes, ambres, noires, speciales"
   logic="or">
//show anything
</txp:smd_if>

Which failed because one of them matched exactly. What you probably meant was:

<txp:smd_if
   field="txpvar:section"
   operator="not, not, not, not, not"
   value="brunes, blondes, ambres, noires, speciales"
   logic="or">
//show anything
</txp:smd_if>

But the notin version is probably more efficient. And jakob’s is even better if it does what you want.

Hope that helps.

Hey Stef

Thanks for the wonderful plugin.

I have a problem constructing the correct call, and I am looking for guidance.

Currently my code looks like this:

<txp:variable name="direction" />

<txp:smd_if field="txpvar:direction" operator="in" value="Drama/Poetry/Fiction/Non-Fiction" logic="or">
<txp:output_form form="contributors_list" />
</txp:smd>

<txp:variable name=“direction” /> is populated through PHP from my site menu structure ?Drama ?Poetry ?Fiction ?Non-Fiction etc.

Parsing Drama, Poetry and Fiction work and they call <txp:output_form form=“contributors_list” /> but Non-Fiction does not. At first I thought it was the hyphen (dash) that was the problem so I removed it and that didn’t fix the problem.

But if I change the Non-Fiction to Non-Fict it will now call <txp:output_form form=“contributors_list” /> so it seems Non-Fiction doesn’t work because it contains “Fiction”.

I tried <txp:smd_if field=“txpvar:direction” operator=“eq, eq, eq, eq,” value=“Drama,Poetry,Fiction,Non-Fiction” logic=“or”> but it fails as well.

Preferably I would like to use “Non-Fiction” in the variable because it has downstream code that matches my category names.

Thanks in advance.

Very strange indeed. I tried it on my test box using a sanitised, hard-coded value of direction and it worked fine. Here’s my code. Note that I tidied up the closing smd_if tag too (but that probably doesn’t have a bearing on it) and dropped the logic attribute since the in operator implies it.

<txp:variable name="direction" value="Non-Fiction" />

<txp:smd_if field="txpvar:direction" operator="in" value="Drama/Poetry/Fiction/Non-Fiction">
Match made in heaven.
<txp:else />
No match this time :-(
</txp:smd_if>

So I wonder if there’s something else at play here. Firstly, could you go back to basics, copy the code above and see what you get out. If it works we may need to investigate how your direction variable is being populated. Perhaps it has a rogue space on the end of it or something, and it needs trimming first (though that wouldn’t explain why Non-Fict worked).

A few things you can try:

Add debug="2" to the smd_if tag and check the values it is comparing match what you expect.
Swap the order of the items in the value attribute list so Non_Fiction comes before Fiction.
Check you’re using the very latest plugin version (0.91) or try the beta 0.92 (which I doubt will affect anything in this instance because it only adds pref matching support).

Past that I’m not sure what could be going on. If none of the above fixes it, by all means drop me a temporary login to the site (if possible) and I’ll see if I can figure it out in situ.

Thank you very much Stef, unbeknownst to me there was a char limit exception on PHP code that populated direction. I thought I had sanitized my test before contacting you, thanks for the help in confirming that it was my problem and not a problem with smd_if.

Testing here

Calling it as such:

<txp:smd_if field="excerpt" operator="isempty"> aaaaaa <txp:body /><txp:else /> bbbbbb
<txp:excerpt /> cccccc <txp:permlink>more</txp:permlink> 
</txp:smd_if> dddddd

Smd_if plugin seems to be working correctly on the frontend; I just want to make sure I’m doing it right/am I missing something that’s causing the error?

alicson · 2017-03-06 05:19:43

Okay so plugin help indicates that my usage won’t work (although it seemed to, on the frontend), however I’m not so far able to wrap my head around what the correct tag should be.. I would just like to check whether the excerpt field is empty (or not).

Doesn’t if_excerpt do the job for you? And don’t worry about any ‘unregistered tag’ warnings: they’re just warnings for now and will be for a version or two of Textpattern yet. I’ll tend to each plugin as I get a chance.

Documentation didn’t indicate that it will parse txp:else — I need it for “if_no_excerpt”. If it will parse txp:else then it will yes do the job :)

All conditional tags support <txp:else />.

alicson · 2017-03-06 09:54:30

Yay then if_excerpt is perfect :) (Documentation seems pretty consistent about individually mentioning availability of txp:else for most conditional tags.)

Am I using smd_if correctly here or can I manage this one with built-in tags too? <txp:smd_if field="category1, category2" value="ridiculi">

In an article list page:

<txp:if_category name="ridiculi">
        ...
</txp:if_category>

In an article form:

<txp:if_article_category name="ridiculi">
        ...
</txp:if_article_category>
