Using selectors instead of AND / OR ?

[doolak]

Well, i guess i just have to make a break and catch some sleep...

I want to include a file just if the current page does not use specific templates, but i cannot get it to work with PW selectors somehow in the way like this:

$select = $pages->find("template=news|news_article");
    if ($page->id != $select) {
        include ("./recent_news.inc");
    }

or maybe:

if ($page->template != news|news_article) {
include ("./recent_news.inc");
}

I know i am running somehow in the wrong direction, so for now i am using this:

if (($page->template!=news) and ($page->template !=news_article)) {
include ("./recent_news.inc");
}

... which works, but it does not make me happy, because i know there has to be a different approach.

Would be so great if you please push me in the right direction...

There's nothing wrong with your final option, except my personal preference is && instead of "and" or "AND".

[doolak]

I just thought that there is a PW-specific solution for this which may be suitable e.g. if you have a lot of selectors which you want to exclude...

It does sound like you should be able to do this from reading the API pages on Selectors, but I can't get it to work and it certainly would be neater:

if ($page->find('template!=template1|template2') {
    // Do your thing
}

[doolak]

Yes, that does not work - same as my attemps above. But i guess there is just a little mistake in thinking somehow...

I just tried this, which works for ONE template, but the docs suggest it should work with a selector:

if ($page->is('template!=template1')) {

Found that on this page: http://processwire.com/api/variables/page/

I need to read the full docs sometime - I've still not done that yet and there is a LOT in there

But still, that doesn't do what you're attempting!

In fact, according to that page, $page->find will search children, grandchildren etc but not the current page.

Here's the answer:

if (!$page->matches('template=template1|template2')) {

Try that one

[doolak]

LOL - yes, and using template1|template2 works like OR - so that's why i tried my first described solution.

But it works fine as it is now - so no need to spend too much time with this - it's just as you said, PW is full of possibilities and it just does not go out of my mind because i know there is a very simple solution somewhere in the API... ;-)

Try my last edit to my previous post

[doolak]

Uhh, i tried $page->matches, but not as you described it with !$page - that looks good, i will have a try!

[Pete]

It seems to work for me, but only with the ! at the front, which actually makes more sense when you read it:

"If not page matches template template1 or template2"

makes more sense than

"If page matches template not template1 or template2"

The second one sounds like WillyC

Perfect! Works like a charm.

And imagine the code without the API if you have a lot of exclusions like this:

if ($page->find('template!=template1|template2|template3|template4, name=Peter|Paul|Mary, age>21) {
    // Do your thing
}

It would be a quite long repetition of if (($page->template!=news) && ($page->template !=news_article)) && ...

[Pete]

That's why I wanted to work this one out - I've got a lot of repetition in some templates on one site so this will streamline things nicely!
