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.
