Passing variables in Url

[spamec]

Hi,

I'm developing my first site with PW. Got it brilliant idea, but head cant get around old thinking

My problem: I have to make a list of news categories with links to news-list template with specific category (to filter news out).

Category list:

  <?php $newsIndex = $page->find('template=news-list'); ?>
  <?php $categories = $pages->get('template=news-categories')->children;?>
  <?php foreach($categories as $c): ?>
	<?php echo "<li><a href='{$newsList->url}{$c->path}'>{$c->title}</a></li>"; ?>
  <?php endforeach;?>

Filtering news:

$selectedCategory = '';
$news = $page->children("category={$selectedCategory}, sort=-date");

Question:

• How to create url to $newsList page with category as parameter?
  
• How to get parameter from url and then filter news out?
  

Maybe, there's any section in API covering this topic (I didnt found it)

Hi spamec and welcome to the forums!

You are looking for $input->urlSegments(n):

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

Of course you can use get-variables also, and access them from $input->get('parametername')

Urls you have almost right, just change {$c->path} => {$c->name}

Thanks apeisa for support,

creating url is working (was really close), but I'm facing new problem.

My structure:

/news - news-list

/story/news-name - news entry

/news/category-name - which is the case, now when I enter this url I get 404, which is true as page with category-name doesnt exists...

I used to work with MVC pattern, so this is new situation for me (sorry for stupid questions)

Ah, you just need to edit your news template settings, urls tab and allow url segments.
