[plugin downloaded] downloads.
` * And here’s the basic PHP I’ve constructed to process and echo the calculation: * ```to go.
``` * As long as I manually replace _x_ with a whole integer, the calculation occurs and outputs properly. However, I’d like to define the “downloads” variable using the shortcode download figure. * I’ve tried various permutations of [`do_shortcode`](http://codex.wordpress.org/Function_Reference/do_shortcode) to no avail. * Does anyone else have any suggestions?

When uncommented, the function also outputs the shortcode properly, but I still can’t seem to achieve what I’m trying to do, namely, auto-populate the “download” definition with the shortcode figure so the calculation is always correct per the actual plugin download number. * Moderator [bcworkz](https://wordpress.org/support/users/bcworkz/) * (@bcworkz) * [14 years ago](https://wordpress.org/support/topic/calculation-with-shortcode/#post-2799291) * Have you tried explicitly casting the shortcode’s download value as an integer, either with (int) or intval()? The automatic type casting doesn’t always work as we think it should. * Thread Starter [oqm4](https://wordpress.org/support/users/oqm4/) * (@oqm4) * [14 years ago](https://wordpress.org/support/topic/calculation-with-shortcode/#post-2799292) * Thanks so much for the tip, bcworkz. * How, exactly, would you suggest integrating those? I’ve tried wrapping the shortcode statement in various ways but to no avail. * Moderator [bcworkz](https://wordpress.org/support/users/bcworkz/) * (@bcworkz) * [14 years ago](https://wordpress.org/support/topic/calculation-with-shortcode/#post-2799315) * I just noticed the line you commented out, which explains more of what you’re trying than anything. Pardon my confusion. It can be difficult to programatically use shortcode output because it’s typically wrapped in HTML. Better to directly use the plugin object’s methods to directly get what you need. Not tested, but something along this line might be the direction to take: * ``` $plugin = new PluginInfo(); $info = $plugin->get_plugin_info(); $downloads = intval($info['downloaded']); ``` * You probably don’t need intval() in this case, but I left it in just as an illustration. * Alternately, if you’d rather just use the shortcode directly, you could adjust the downloads value the shortcode outputs by hooking the filter ‘plugin_info’ like this: (again not tested) * ``` function myfunction( $info ) { $info['downloaded'] = 35000000 - $info['downloaded']; return $info; } add_filter( 'plugin_info', 'myfunction' ); ``` * This way, using `[plugin downloaded]` in your template will now return the adjusted download number. * Thread Starter [oqm4](https://wordpress.org/support/users/oqm4/) * (@oqm4) * [14 years ago](https://wordpress.org/support/topic/calculation-with-shortcode/#post-2799319) * Hi, bcworkz: * Thanks so much for the suggestions, and your thinking makes tons of sense. Using the plugin’s object methods directly is inspired. * However, I’m afraid neither of the above work, either when called from my theme’s functions.php file or entered directly into the page. * This problem might be intractable, and I can just keep updating the value manually. That’s just so inelegant … * Moderator [bcworkz](https://wordpress.org/support/users/bcworkz/) * (@bcworkz) * [14 years ago](https://wordpress.org/support/topic/calculation-with-shortcode/#post-2799347) * Sorry my code doesn’t work, some debugging work should get it working. It is not an intractable problem though, if all else fails, you can capture the HTML output, figure out how to parse out the number, adjust it, then replace the adjusted number back into the HTML before echoing out to the page. * Inelegant doesn’t begin to describe manual updating! You’ve no doubt spent way more time on this than it deserves, so I understand you wanting to give up. Maybe set it aside, and attack again later, there has to be an answer.
