How to create a shortcode with 1 parameter (atts)
Here is how you should create shortcode. First you will have to define $atts item in get_userdata because $atts is an array. Also I think there is also some issues with uppercase attributes names, so you should use attribute in lower case. So instead of userID, use userid. function getUserEmail_func( $atts ) { $user_info = … Read more
Redirect function inside a Shortcode
As @Rarst explains, shortcodes normally run too late for you to redirect from inside one. They usually run on the the_content hook which is well after content is sent to the browser. If you need to redirect based on the presence of a shortcode you need to check for that shortcode before any content leaves … Read more
Shortcode always displaying at the top of the page
You can buffer the output like this: ob_start(); include(locate_template(‘loop-‘.$module.’.php’)); return ob_get_clean(); EDIT. I tried this, worked fine. function friendly_loop_shortcode( $atts, $content = null ) { extract( shortcode_atts( array( ‘category’ => ”, ‘module’ => ” ), $atts ) ); ob_start(); include(locate_template(‘loop-‘.$module.’.php’)); $output = ob_get_clean(); //print $output; // debug return $output; } if (!is_admin()) { add_shortcode(‘test’, ‘friendly_loop_shortcode’ … Read more
Show shortcode without executing it
To display a shortcode instead of rendering it you have two options: Write [[shortcode]]. WordPress will show this as [shortcode]. Escape the [, write it as as [ or [.
Pass boolean value in shortcode
Is easy to use 0 and 1 values and then typecasting inside the function: [shortcode boolean_attribute=”1″] or [shortcode boolean_attribute=”0″] but if you want you can also strictly check for ‘false’ and assign it to boolean, in this way you can also use: [shortcode boolean_attribute=”false”] or [shortcode boolean_attribute=”true”] Then: add_shortcode( ‘shortcode’, ‘shortcode_cb’ ); function shortcode_cb( $atts … Read more
How do I escape a ‘]’ in a short code?
I don’t know of an official escape syntax for shortcodes and there likely isn’t one. When wordpress parses for shortcodes it looks for [ and ]. If you want to use square brackets within a shortcode, using the respective html ASCII entities escapes them. I.e. replacing [ by [ and ] by ]. WordPress will … Read more
What does extract( shortcode_atts( array( do?
shortcode_atts() works like array_merge(): It merges the second list of arguments into the first one. The difference is: It merges only keys present in the first argument ($default). extract() then takes the array keys, sets these as variable names and their values as variable values. ‘w’ => ‘500’ in your example becomes $w = ‘500’. … Read more
Conditionally Loading JavaScript/CSS for Shortcodes
Based on my own experience, I’ve used a combination of method 1 & 2 – the architecture and footer scripts of 1, and the ‘look-ahead’ technique of 2. For the look-ahead though, I use regex in place of stripos; personal preference, faster, and can check for ‘malformed’ shortcode; preg_match( ‘#\[ *shortcode([^\]])*\]#i’, $content ); If you’re … Read more
Enqueue Scripts / Styles when shortcode is present
I found an other way that works well for me: When initializing the plugin, do not enqueue your scripts and styles, but register them with wp_register_style and wp_register_script. Next you can load the script/style on demand. For example when you render a shortcode with wp_enqueue_style(“your_style”) and wp_enqueue_script(“your_script”). Here is an example plugin using this method … Read more
