Show Secondary Sidebar on Category pages (archive)
Use the is_category() WordPress function to determine if you are in a category template. <?php /** * Alternate Sidebar Template * * If a `secondary` widget area is active and has widgets, * and the selected layout has a third column, display the sidebar. * * @package WooFramework * @subpackage Template */ // If this … Read more
I would like to feature a tip on the homepage
You can place another loop on the template, for example below the first loop. Multiple loops documentation: http://codex.wordpress.org/The_Loop#Multiple_Loops_Example_1 <?php if (have_posts()) : ?> <?php while (have_posts()) : the_post(); ?> <!– your first loop … –> <?php endwhile; ?> <?php endif; ?> <?php wp_reset_query(); $tips_query = new WP_Query( ‘category_name=tips&posts_per_page=1’ ); ?> <?php if ($tips_query->have_posts()) : ?> … Read more
Only first category!
If I understand you correctly, you want to display the parent Categories themselves, and not their posts, correct? get_terms is what you need. $top_level_categories = get_terms( ‘category’, array( ‘parent’ => 0, // This will get ONLY top level items ‘hide_empty’ => false // This will make sure even empty categories are returned ) ); print_r( … Read more
Generating a feed of all but one category of posts
I think you can go even simpler in the coding. Just add the below to your functions.php file within your theme folder. function myFeedExcluder($query) { if ($query->is_feed) { $query->set(‘cat’,’-73,-9′); // categories 73 and 9 are being excluded } return $query; } add_filter(‘pre_get_posts’,’myFeedExcluder’); Note particularly that multiple categories can be excluded by separating them with commas. … Read more
Category link redirect to custom template page instead of index.php?
Your question implies that index.php is a page to be redirected to, it isn’t, it’s purely a template file. It implies that single.php being loaded is what makes a page singular, or that loading the page.php template will give you a page, when it’s actually the other way around. I strongly recommend reading about the … Read more
custom query for both category and pages using global $wpdb;
What about using the UNION? Just an example: (SELECT * FROM $wpdb->posts (with JOIN and WHERE as needed)) UNION (SELECT * FROM $wpdb->posts (with WHERE to select pages)) GROUP BY/ORDER BY The select(s) must be in parenthesis to use an order by for the whole union result. As a second option, you can use a … Read more
javascripts files not linking to my category slugs?
Relative URLs are best avoided in WP, so use absolute URLs instead. Also, you should load javascript files using the correct method, ie by using the wp_enqueue_script() function hooked to the wp_enqueue_scripts action hook. Doing both of these things will sort out your issue. Using wp_enqueue_script() will also allow you to define dependencies so, for … Read more
How to hide widget from certain category
I think you might mean is_category()? Codex: is_category()
Random category with recent post title and thumbnail
If I’m not wrong a the_post() function will take the post info into the loop. If so, then the the_title() and the_post_thumbnail() will do the rest for you. <?php //display random sorted list of terms in a given taxonomy $counter = 0; $max = 5; //number of categories to display $taxonomy = ‘category’; $terms = … Read more
