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.
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.
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.
This automatically generated starter code can be copied pasted into your functions.php file.
Here you enter the meta value.
Note: This component is for advanced users only. Information on writing PHP and WordPress filter functions is beyond the scope of this document.
