Using Woo Canvas and probably all woo themes with their custom framework, you will run into strange things from time to time.. If you try to use pre_get_posts to filter the query of posts in the blog homepage, you find that it doesnt work. So here is a way I found to do it: // Exclude categories on the “Blog” page template. add_filter( ‘woo_blog_template_query_args’, ‘change_posts_per_page’, 10 ); function change_posts_per_page( $args ) { global $woo_options; if ( isset($woo_options[‘woo_posts_limit’]) && !empty($woo_options[‘woo_posts_limit’]) ){ $args[‘posts_per_page’] = $woo_options[‘woo_posts_limit’]; } print_r(”); print_r($args); print_r(‘ ‘); return $args; } // End woo_exclude_categories_blogtemplate()

Quick Simple example of add_filter – sticking something in the bottom of the_content(). // filter to add stuff to the end of content in posts function add_stuff_to_content($content) { global $post; if ( ‘post’ != get_post_type() ) { // limit this to only the post type you want to alter return $content; //exit; } $original = $content; $morestuff .= ‘<div class=”stuff”>Extra Stuff!!</div>’; $thecontent = $original.$morestuff; // puts more stuff right after post return $thecontent; } add_filter(the_content, add_stuff_to_content);

This goes in the functions if you need to allow other file types to upload to the library. The example adds two e-book formats. // add types to allowed uploads add_filter(‘upload_mimes’, ‘custom_upload_mimes’); function custom_upload_mimes ( $existing_mimes=array() ) { // add the file extension to the array $existing_mimes[‘epub’] = ‘mime/type’; $existing_mimes[‘prc’] = ‘mime/type’; // call the modified list of extensions return $existing_mimes; }

Here is cool little functionto stick in functions to help you see which template you are viewing when looking at a page in the browser. It simply shows the template file name in the footer. It is based on a plugin called “What Template” but has the improved feature of only working when you are logged in as admin. if ( is_user_logged_in() && current_user_can(‘manage_options’) ) { add_action(‘wp_footer’, ‘show_template’); } function show_template() { global $template; print_r($template); } ?>

Hides meta boxes in admin forms as needed. 1. This is great for when a plugin adds a metabox to your post or page form and you want to hide it. 2. the tricky part is finding the name of the box – as with the magicmembersdiv box in example below. You can usually find this by searching the  plugin for the add_meta_box() call where they add the box – i.e. add_meta_box(‘magicmemberdiv, ‘….’,’…….’,…) // hide admin meta boxes that we are not using function remove_themeta_box() { remove_meta_box( ‘magicmemberdiv’, ‘post’, ‘side’ ); remove_meta_box( ‘magicmemberdiv’, ‘page’, ‘side’ ); remove_meta_box( ‘magicmemberdiv’, ‘homepage’, ‘side’ …

wp_redirect() is a cool way to redir someone based on certain circumstances, like user permissions. So far I have seen this help in two applications. 1. use just the at the top of template file to redirect a page to another page if user is logged in. I.E. – if you want to redirect a logged in user away from this page to another…. if(is_user_logged_in()) { wp_redirect(“/member-profile/”); exit(); } 2. use in functions to redirect logged in users to other member page if they are not admins. Then you can hook it in the action of entering the admin (admin_init) …

To make stuff work in Android you can use this function in the header.php 1. This replaces the call to the default stylesheet, so if you use this, you need to take out the normal stylesheet line. 2. Most of the heavy lifting seems to be happening with adjusting the initialscale in the viewport meta tag. The biggest issue we have found with Android deals with initialscale. Changing it to 0.25 seemed to make it load the full screen. Though really small it is what most clients seem to want. 3.That said, the function also loads a separate stylesheet for …
