Custom Filter
If you’re comfortable writing PHP and are familiar with WordPress filters, the Custom Filter Component can be used to create your very own conditional display-logic functions.
A) Filter
Here you can enter a custom filter tag for your function. If left blank, a default filter tag will be generated based on the Preset’s title.
B) Callback
Here you can enter a custom callback name for your function. If left blank, a default callback name will be generated based on the Preset’s title.
C) Code
This automatically generated starter code can be copied pasted into your functions.php file.
Note: This component is for advanced users only. Information on writing PHP and WordPress filter functions is beyond the scope of this document.
