The solution below will parse the comma separated values passed to the shortcode’s type parameter. We’ll also strip out any whitespace surrounding the values which is a usability improvement (see example 2 after the code below). add_shortcode( ‘related’, ‘wpse_related’ ); function wpse_related( $atts, $content=”” ) { // User provided values are stored in $atts. // … Read more
There’s a get_image_send_to_editor() function in wp-admin/includes/media.php that runs this: apply_filters( ‘image_send_to_editor’, $html, $id, $caption, $title, $align, $url, $size, $alt );. Try hooking that filter. Edit: Help with the filter call… Your call to hook the callback would look like this: add_filter(‘image_send_to_editor’, array(&$MyClassReference, ‘filter_iste’), 10, 8); The 10 is the priority, you might need to adjust … Read more
Simple answer: add_shortcode( ‘hidemytext’, ‘__return_false’ ); But shortcodes should never be used like that. Imagine what happens when the plugin or theme with that shortcode is turned off: everyone can see the content now. This is not very user friendly.

Is it Ok? Yes! Is it Optimal? No What Would Be Better? Shortcodes map on to PHP functions, so why not cut out the middle man and go straight to the original function? Are there any other downsides? Yes! That shortcode had to come from somewhere, now you have a dependency, maybe the plugin that … Read more
Shortcodes are a WordPress thing, hence not being in the PHP manual. What you do want to look at in the PHP manual is the section on callbacks. add_shortcode() accepts a shortcode name, and a callback. In that section of the PHP manual you can see the 3 main types of callbacks: // Type 1: … Read more
Since WooCommerce 3.2, Woocommerce shortcodes and their available attributes have changed. So try the following shortcode instead (for “foo” product category): [product_category limit=”90″ columns=”3″ category=”foo” paginate=”true”] or inside php code: echo do_shortcode( ‘[product_category limit=”90″ columns=”3″ category=”foo” paginate=”true”]’ ); Now you will see that the sorting options dropdown appear.

Use this instead of the line in wich you define $days (your second line): $transient = get_transient( ‘your_transient_key’ ); if( !$transient ): $days = file_get_contents( ‘json_file’ ); set_transient( ‘your_transient_key’, $days, DAY_IN_SECONDS*7 ); else: $days = $transient; endif; $days = json_decode( $days ); … May be a bit rough but you get the idea.
