Description
The Shortcode Callback plugin allows you to use a [callback] shortcode to execute arbitrary PHP code wherever the shortcode is used.
Usage
Execute someFunction() and insert whatever it returns with the following shortcode:
[callback function=”someFunction”]
Example shortcode to include a PHP file (the path is relative to WordPress’ ABSPATH), then insert the results of someFunction() where you used the shortcode:
[callback include=”custom/filetoinclude.php” function=”someFunction”]
Shortcode example that includes a PHP file (the path is relative to WordPress’ ABSPATH), then passes a paramter to someFunction() and returns the results where you used the shortcode:
[callback function=”someFunction” include=”custom/filetoinclude.php” param=”something”]
The format to call a class/method with the shortcode is exactly the same as above, except you specify the class::method in the “function” attribute of the shortcode.
[callback function=”someClass::someFunction” include=”custom/filetoinclude.php” param=”something”]
There is an example (with PHP code) over here.

FAQ
- Do you have an example of where the Shortcode Callback plugin is used?
-
I built this plugin primarily because I needed a way to inject the “Daily Yield” and “Total Yield” numbers to my solar power chart page.
- The shortcode being used:
-
[callback function=”DigitalPointElectricity::total_output” param=”daily” include=”custom/Electricity.php”]
- The `custom/DigitalPointElectricity.php` file being called by the shortcode:
-
<?php
class DigitalPointElectricity { public static function total_output($timeframe) { $totals = $GLOBALS['memcache']->get('shawnhogan-pv-total'); if ($timeframe == 'total') { return $totals->Items[2]->TotalYield; } elseif ($timeframe == 'daily') { return $totals->Items[1]->DailyYield; } } }
