Title: Example of function implementation Last modified: August 22, 2016 --- # Example of function implementation * Resolved [tdmohr](https://wordpress.org/support/users/tdmohr/) * (@tdmohr) * [11 years, 9 months ago](https://wordpress.org/support/topic/example-of-function-implementation-1/) * Hi Luke, * Thank-you for the great plugin. It really is exactly what I was looking for! * I know you don’t want to provide any support on this but I just wanted to mention that I am also having problems getting the filter example you posted above to work. * Displaying a testimonial via shortcode or widget simply do not appear to fire the ct_before_render_testimonial event. Either that or the example posted is not being correctly parsed in my functions.php file. Other filters I have implemented are working properly though… * Can you please confirm that this should be working under wordpress 3.9.1? * I would love to properly customise the output of the testimonial without hacking the class.wp-testimonial.php file. * Thanks for any advice you can provide, Tim * [https://wordpress.org/plugins/clean-testimonials/](https://wordpress.org/plugins/clean-testimonials/) Viewing 9 replies - 1 through 9 (of 9 total) * Plugin Author [lukerollans](https://wordpress.org/support/users/hellolukerollansme/) * (@hellolukerollansme) * [11 years, 9 months ago](https://wordpress.org/support/topic/example-of-function-implementation-1/#post-5182453) * Hey tdmohr, * the `ct_before_render_testimonial` action fires immediately when the `render()` function runs to display a testimonial. * What method are you using to display the testimonial(s) on which the event is not firing? * If you aren’t using a shortcode, and instead are using a custom loop or something, then it won’t fire natively. * If you are using a custom loop, say with query_posts or get_posts and displaying them in succession, do `$testimonial = new WP_Testimonial( $the_post_id ); $testimonial- >render();` * If you are using a shortcode, then let me know and we can eliminate that at least. * Feel free to paste me a link to a gist which contains the code that isn’t working( or any sort of link), and I can take a look. Normally I wouldn’t ask this, but you seem to be more on the developer side of things than most users. * Thread Starter [tdmohr](https://wordpress.org/support/users/tdmohr/) * (@tdmohr) * [11 years, 9 months ago](https://wordpress.org/support/topic/example-of-function-implementation-1/#post-5182495) * Hi, * I am using the widget and I’ve also tried the shortcode. The testimonials render in the same default way using both methods. * I think there must be something wrong with my filter implementation. Does this look correct to you? * ``` function render_my_testimonial ( $testimonial, $context ) { return '

' . $testimonial->post_title . '

'; } add_filter( 'ct_before_render_testimonial', 'render_my_testimonial', 10, 2); ``` * The function is located half way through the functions.php file but I’ve tried moving it around with no change. I’ve put an exit(); tag within the function and the site continues loading so I believe the function render_my_testimonial is never called. * The website is currently located on my internal staging servers but if you don’t have any ideas I can upload to an external staging environment which might give you a better idea of what is going on. * Cheers, Tim * Plugin Author [lukerollans](https://wordpress.org/support/users/hellolukerollansme/) * (@hellolukerollansme) * [11 years, 9 months ago](https://wordpress.org/support/topic/example-of-function-implementation-1/#post-5182506) * Hi Tim, * `ct_before_render_testimonial` is an action, not a filter. The filter I think you’re after is `ct_pre_render_testimonial`. * Try this * ``` function render_my_testimonial ( $testimonial, $context ) { return '

' . $testimonial->post_title . '

'; } add_filter( 'ct_pre_render_testimonial', 'render_my_testimonial', 10, 2); ``` * If `render_my_testimonial` returns anything at all, Clean Testimonials will just display that instead of using the default output. It is designed to override the output completely. * Let me know how that goes. * Thread Starter [tdmohr](https://wordpress.org/support/users/tdmohr/) * (@tdmohr) * [11 years, 9 months ago](https://wordpress.org/support/topic/example-of-function-implementation-1/#post-5182512) * Hi Luke, * Thanks for the reply. * Adding the correct filter started interupting the rendering of the plugin but I still didn’t see the testimonial title I was expecting. After a big of extra debugging I found the var $testimonial was blank and $context actually contained the testimonial object. I’m not sure why its not coming through the first parameter… perhaps you can shed some light on this…? * So my working code to achieve a testimonial post title is: * ``` function render_my_testimonial($testimonial, $context) { return '

' . $context->post_title . '

'; } add_filter( 'ct_pre_render_testimonial', 'render_my_testimonial', 10, 2); ``` * I should be good to go from here. * Just FYI… The code I started working from was copied from [your reply](http://wordpress.org/support/topic/example-of-function-implementation?replies=8#post-5770224) in the thread that I originally posted my question in… * Perhaps you should correct it so that others do not get confused, now that it has been tested. * Thanks for your help though, its good to not have to hack the plugin to get the output I need. * Cheers, Tim * Plugin Author [lukerollans](https://wordpress.org/support/users/hellolukerollansme/) * (@hellolukerollansme) * [11 years, 9 months ago](https://wordpress.org/support/topic/example-of-function-implementation-1/#post-5182513) * Hey Tim, * That appears to be a bug.

The fix was simple, the code I supplied you wasn’t 100%. The below will work. * ``` function render_my_testimonial( $default, $testimonial, $context ) { return '

' . $testimonial->post_title . '

'; } add_filter( 'ct_pre_render_testimonial', 'render_my_testimonial', 10, 3 ); ``` * Forgot about the first parameter which is passed down the filter chain. The testimonial object is the second parameter, with context being the third.
