This is mainly for my own records, but the curious thing is that when I do a simple search for “how to replace a wordpress function” or a few derivatives of that phrase I’m usuually returned the following links (at least w/ Google):
However, what I’m really looking to do is basically swap in one of my own functions for a WordPress Core Function. It seems that WordPress’ Pluggable Functions allows me to do that:
The explain it a bit here:
Pluggable functions were introduced in WordPress 1.5.1 These functions let you override certain core functions via plugins. The most up-to-date list of core functions that WordPress allows plugins to override is available at wp-includes/pluggable.php. WordPress loads the built-in functions only if they are undefined after all plugins have been loaded.
Now, this only allows you to replace a limited number of WordPress functions, but it does, what it says it does, and that is to allow you to replace a core WordPress function by using WordPress’ Pluggable Functions.
