Assume that we want to show 5 posts per page for category “WordPress” and 10 posts per page for category “News”, just open the functions.php file in your theme folder and insert these line into it:

add_action('pre_get_posts', 'diff_post_count_per_cat');
 
function diff_post_count_per_cat() {
    if (is_admin()) return;
 
    $cat = get_query_var('category_name');
    switch ($cat) {
        case 'wordpress':
            set_query_var('posts_per_page', 5);
            break;
        case 'wordpress/news':
            set_query_var('posts_per_page', 2);
            break;   
    }
}

Change “wordpress” and “news” into real category names of your blog. Note that in the code above, we use category slug, not original name. If the category is a child category, don’t forget to insert full path (i.e. “wordpress/news” in the example below).

Radi se o fajlu category.php, single_cat_title(); samo prikaze naziv kategorije bez linka. Ovaj kod prikazuje i link i naziv kategorije

$categories = $wp_query->query_vars;
$this_category = get_category_by_slug( $categories['category_name'] );
echo '
'.$this_category->name.'
';

Goes in the element of a theme, in header.php. Example plugin use: add JavaScript code.

Goes in footer.php, just before the closing tag. Example plugin use: insert PHP code that needs to run after everything else, at the bottom of the footer. Very commonly used to insert web statistics code, such as Google Analytics.

Typically goes in the Meta section of a Theme’s menu or sidebar; sidebar.php template. Example plugin use: include a rotating advertisement or a tag cloud.

Goes in comments.php directly before the file’s closing tag. Example plugin use: display a comment preview.

When adding copyright information it is generally a good idea to render the copyright year dynamically. This can be done in many ways, here are 2 most common:

1st way

© 2012. – 2013.

© 2012. - 

2nd way

© 2012. – 2013.

© 

The second way is better when building new websites, since the output will automatically change next year from © 2013. to © 2013. – 2014. if $copyYear is set to 2013.

© 

Sometimes in WordPress the header tags and links start appearing inside the body tag.

This problem generally occurs due to specific encoding of the file. We need to change the file encoding from UTF-8 to “UTF-8 without BOM” (BOM=”byte-order-mark”) and save it again. We can use Notepad++ as it allows us to specify the encoding we want to save the file in.

To change the default encoding for new and/or opened documents in Notepad++ go to Settings -> Preferences -> New Document/Default Directory and under encoding select “UTF-8 without BOM” and select “Apply to opened ANSI files” as well.
