no output from $pages->find("template=category") on home.php

[gtoirog]

and if I do <?php echo $pages; ?>, it prints only a word "Pages". I don't think I'm getting any page in this variable?! Any idea?

Greetings,

What exactly do you want to output?  Which pages/fields/data?

You have to be more specific.

Thanks,

Matthew

$pages->find() will find things; lots of things in some cases (pages) . You need to echo out the ouput.

Do you get any errors?

Is there really a template called "category"?

Does it have any unpublished and hidden pages using it?

In addition, have you read these documentation?

http://processwire.com/api/selectors/

http://processwire.com/api/variables/page/

http://processwire.com/api/variables/pages/

By the way, normally, you don't want to do something like $pages->find() without including a "limit"; It can find lots of things...and eat into your server resources, maybe hang your pages, hence, frustrate your web visitors, etc...

$pages->find is supposed to return multiple pages.

Use $pages->get to get only one page.

So when using find, you need to iterate over your pages:

$foundPages = $pages->find('template=category'); // Don't use $pages as variable name, it's reserved!
foreach ($foundPages as $p) {
  echo "Found page with title" . $p->title;
}

@gtoirog: have you tried reading the docs, most importantly http://processwire.com/api/templates/ and http://processwire.com/api/variables/? This is all explained there

Under the "Home" page, I have a few hidden pages, each with a template called "category". I just want to get the list of those pages filtering with "find("template=category")" and then loop through their children. I don't get anything by doing:

$cpages = $pages->find("template=category");
foreach ($cpages as $cpage){
echo $cpage->title;
}
 

And I don't get any error.

You don't get anything because the pages are hidden. Add this to your selector include=hidden

Please read this page: http://processwire.com/api/selectors/ and specifically this section in relation to access control in selectors.

Thank you guys! Thanks, Kongondo. "include=hidden" works. Great community for newbies like me :-P Should do some more reading and use the cheatsheet more too. Processwire rocks!

Nice. You may want to mark this thread as "solved"
