[Resolved] Add Filter to Theme's functions.php

[Dominik Günder]

Hey there,

today i’ve got two questions if you don’t mind.

I want to add the following to the themes functions.php:

add_filter(‘wp_feed_cache_transient_lifetime’,create_function(‘$a’, ‘return 60;’))

This will force RSS Widgets to refresh every 60 seconds so i always have got the latest information from my forums.

1.) When you release a theme update, all my custom information from functions.php are gone. Is there a clean way to prevent this?

2.) After the latest theme update my string does not work anymore. I added it – as usual – to “forefront”‘s functions.php but then my page won’t load. (Just shows a white page)

Do you have any ideas about this?

Thanks in advance,
Dominik

Hi Dominik,

1. Yes – this is annoying, and the trouble with releasing child themes. Your best bet is to use this plugin: https://wordpress.org/plugins/pluginception/

It allows you to create a plugin that you can add your PHP to – this way, theme updates won’t ever touch your custom functions.

2. Make sure it looks like this:

add_filter('wp_feed_cache_transient_lifetime',create_function('$a', 'return 60;'));

Hey Tom,

thanks for the quick answer. Pluginception works perfectly. I’m wondering how you always find these awesome plugins.. I’ve been searching for this over the last days. 😉
