You don’t ever directly use (as in, select as a Page template) either front-page.php or home.php. WordPress uses these template files automatically, according to the Template Hierarchy rules. The front-page.php template file is used to display Site Front Page, whether you have set the site front page to display a static Page or the Blog … Read more
Here is something i cooked up which was taken mainly from the plugin Overwrite Uploads but without the extra stuff add_filter(‘wp_handle_upload_overrides’,’noneUniqueFilename’); function noneUniqueFilename($overrides){ $overrides[‘test_form’] = false; $overrides[‘unique_filename_callback’] = ‘nonUniqueFilenameCallback’; return $overrides; } function nonUniqueFilenameCallback($directory, $name, $extension){ $filename = $name . strtolower($extension); //remove old attachment removeOldAttach($filename); return $filename; } function removeOldAttach($filename){ $arguments = array( ‘numberposts’ => … Read more
A child theme may have declared these functions already with a slightly different inner logic. The functions.php from the child theme is loaded before the file from the parent theme. Without this check you would get the Cannot redeclare … error. Plugins can create functions too, so this problem is not restricted to the themes … Read more
To provide a default template that can be overwritten by a theme hook into template_include like the linked questions suggest. You get the template WordPress wants to use as a parameter. If that is not the file you want – replace it with your plugin’s file: add_filter( ‘template_include’, ‘wpse_57232_render_cpt’, 100 ); /** * Provide fall … Read more
The id parameter in register_sidebar is not directly related to the html output. It is used to identify each sidebar when the $widget_object is built. The class should be added to the before_widget markup. http://core.trac.wordpress.org/browser/tags/3.4.1/wp-includes/widgets.php#L1128 is where the class gets parsed.
Don’t use query_posts in the template for simple modifications of the main query. Use the pre_get_posts action instead to modify the query before it runs: function wpa_date_posts_per_page( $query ) { if ( !is_admin() && $query->is_date() && $query->is_main_query() ) { $query->set( ‘posts_per_page’, 5 ); } } add_action( ‘pre_get_posts’, ‘wpa_date_posts_per_page’ );
Code in a functions.php (or any file loaded by that file) should not run automatically, eg. when the file is included. All code should be bound to hooks. That means, you don’t need a special action in the parent theme. The child theme can turn off all parent theme callbacks with remove_action() and remove_filter(). But … Read more
In your theme’s functions.php file you can add add_image_size( ‘thumb’, 600, 350, true ); add_image_size( ‘thumbnil’, 600, 350, true ); add_image_size( ‘medium’, 600, 350, true ); add_image_size( ‘large’, 600, 350, true ); add_image_size( ‘post-thumbnail’, 600, 350, true ); add_image_size( ‘{custom-image-type}’, 600, 350, true ); For more information have a look at http://codex.wordpress.org/Function_Reference/add_image_size
When accepting user data inputs, I think that data validation must be performed if possible, not only sanitization. For example, you could expect a number, a bool value, a text string (even when the input is a selectbox it can have a string value), etc. You can santize for that data types; then you can … Read more
Your theme should not depends on any external link library. There is no guarantee when that library can be taken down. That’s the reason all of your theme assets should be package with theme, to prevent the future risk.
