On plugin deactivation hide its shortcode

I’m afraid hiding the shortcode once the plugin is deactivated is simply not possible. The only way to “hide” a shortcode from the content is to register the shortcode with a calback that returns nothing, as in: add_shortcode( ‘related’, function(){ return null; } ); But of course you cannot do that without an active plugin. … Read more

Splitting Shortcode Attributes not working

The var_dump() before using shortcode_atts() reveals the problem. Lets look at that output in a more readable format: array(5) { [0] => string(42) “phonePrefix=”0581″,phoneFlatOption=”true”,” [1]=> string(21) “accessModeDsl=”true”,” [2]=> string(24) “accessModeCable=”false”,” [3]=> string(22) “accessModeLte=”false”,” [“accessmodesat”]=> string(5) “false” } As you can see, the attributes are not being parsed correctly. Instead of ‘attribute’ => ‘value’ you’re getting … Read more

If I got it right – I can only use wc_get_product if the current page is using the WooCommerce plugin. Since it’s a post page it does not includes the WooCommerce plugin and hence I can’t use the wc_get_product. (Please currect me if I’m wrong – I’m here to learn 😀 ) You are wrong … Read more

If numberposts = -1 offset won’t work

This problem has pretty simple explanation 😉 All you need to do is to take a look at Codex page for WP_Query and read about offset parameter: offset (int) – number of post to displace or pass over. Warning: Setting the offset parameter overrides/ignores the paged parameter and breaks pagination (Click here for a workaround). … Read more

Shortcodes output in the wrong order

the_time() is the problem here. It echoes its output. Shortcodes, effectively, happen in this order: The text containing shortcodes is parsed to find shortcodes. Each shortcode is executed and its output stored. Each shortcode is replaced with its output. The problem is that if you echo inside a shortcode, its output will be printed to … Read more

passing multiple parents value into a shortcode

If you’re passing in a comma-delimited list of parent IDs when you call the shortcode, it’s pretty easy to turn this to an array. For example, using [scname parent=”5,10,15″]: function andrew_child_loop_shortcode_new ( $atts ) { global $post; $thePostID = $post->ID; $atts = shortcode_atts( array( ‘posts’ => 20, ‘parent’ => $thePostID ), $atts ); // Turn … Read more

check for shortcode in post/pages AND widgets AND template files

Someone may correct me, but I think as of Version 3.3 you can enqueue scripts and styles “inline” of a post. Means: you can add your wp_enqueue_script / style inside your shortcode function and WordPress will add them to the footer…since it’s too late to add them to the header. Means: It will just work … Read more
