Shortcode Callback

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.

1. Upload shortcode-callback folder to the /wp-content/plugins/ directory.
2. Activate the Shortcode Callback plugin through the ‘Plugins’ menu in the WordPress admin area.

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;
        }
    }
}
