jmd_count: Count MySQL tables
Pretty simple plugin – count MySQL table rows and optionally evaluate them in a conditional.
(Split from jmd_dashboard).

Re: jmd_count: Count MySQL tables
Neato.
I used the first function to count articles, comments, etc. :)

Re: jmd_count: Count MySQL tables
Yeah, nice one jm. Very useful, thanks.
Out of curiosity, was there a reason you wrote your own SQL statement in the code instead of using safe_count()?

Re: jmd_count: Count MySQL tables
Wow, jm! Didn’t expect it so quickly! Good to have it!
In the help’s example you use it for statistics. I could imagine it as something more valuable: For a small business, if stocks go below n, automatically send «Go baking!» mail to the bakery at OnUnload. Or similar, if site comments begin to pile up, red warning lamps could flash on the dashboard/assistant slave is skyped up ;)
Thanks, jm!

Re: jmd_count: Count MySQL tables
Ah, sorry missed the “ridonkulous” example.
Would you please be so kind and explain a little more on
<txp:jmd_count_value/> Returns the value from jmd_if_count.
Where is it necessary/different from jmd_count?

When you use jmd_if_count it sets a global variable on the page with the return value of the specified count. jmd_count_value simply retrieves that value of the “last if” in case you need it later on the page as well as the conditional behaviour.

Re: jmd_count: Count MySQL tables
Thanks, Stef! Figured it out in the meantime, but can’t get if_count working.
I’m using exactly the same WHERE phrase as in a working instance of jmd_count:
<txp:jmd_if_count eval=">5" table="textpattern" where="image != ''">More than 5 images used in articles</txp:jmd_if_count /> (Rather useless stuff, but … well, for training ;) It doesn’t output the enclosed content, in no constellation of >5, <5, =5. It complains about the unexpected equal-sign/T_string (IS) or does nothing, whereas if_count seems to give me the total amount of articles. Am I missing something from the plugin help again?

Re: jmd_count: Count MySQL tables
Uli, that cannot be parsed correctly by the tag parser in TXP 4.0.6 and earlier. (will work in 4.0.7)
The > before the 5 will close the tag prematurely.
Also, this: </txp:jmd_if_count /> should be </txp:jmd_if_count>

Re: jmd_count: Count MySQL tables
</txp:jmd_if_count />
ooOOPPS! =)
Edit: I developed the minimal parser: Removing the second slash shows all the fine errors you’d expect it would :))

Just in case users want to count a whole table without a where clause – it’s unfortunate that safe_count and safe_rows have where hardcoded :(.

It’s all your fault Ruud! I just love the new tag parser :).
I’ve updated the plugin to 0.1.1 with 4.0.6 compatibility. Uli, use eval=">5".

I didn’t employ smd_query previously ;) So “image” exists in “textpattern”, yes.

eval=">5".
Sorry for all that hassle, but I’m really grateful that you did :)

Ah right, I forgot article_image is just called Image. Self: read your own hint!

It was only one line, so it’s not a big deal. Enjoy!
