These two functions accomplish two different things. wp_footer() is a hook used in your footer.php template file to ensure that the right code is inserted (from the core/plugins/etc) into the right place. get_footer() is used in your other template files to call for the code in your footer.php template file. So in simpler words wp_footer() … Read more
The filter is manage_{$screen->id}_columns, and $screen->id is edit-category, giving you manage_edit-category_columns. I found this by placing a var_dump() in get_column_headers(), which is called by print_column_headers(), which is called in wp-admin/edit-tags.php, the page where you edit the category items.
Today I run a test over my db to explore the speed difference between accessing a key from options, custom table & transients.

Filters? Anyone? There’s no filter there to help: page_template_dropdown($template); is used to build the drop down and it’s not filterable. Sneaking into the Templates Array? To build the drop downs contents, the core meta box uses get_page_templates(). From inside, the function looks like the following: $themes = get_themes(); $theme = get_current_theme(); $templates = $themes[$theme][‘Template Files’]; … Read more
I would use the is_page_template() conditional: if ( is_page_template( ‘page-courses.php’ ) ) { // The current page uses your // custom page template; // do something } Edit You would use this conditional inside your filter callback: function wpse83525_filter_the_title( $title ) { if ( is_page_template( ‘page-courses.php’ ) ) { return ‘Custom Title’; } return $title; … Read more
It would be nice if WordPress had a standards based cache directory, but since it doesn’t I think the best option is to keep it in the plugin folder itself. Uploads are in my opinion for actual uploads and cache files are not really considered as such. I think it easier to manage , reduces … Read more
For testing purposes you can use the log system (php_error.log): error_log(‘Plugin activated’, 0); // Check for DB table existance if(!$this->hasDBTable()){ error_log(‘Database not present’, 0); if($this->createCELabelsDBTables()){ error_log(‘Database was created.’, 0); } else { error_log(‘Error creating the CE Labels Plugin db tables!’, 0); } } else { error_log(‘Database OK’, 0); } To output error to the user … Read more
