Back WordPress API to the content.

You can request some* functions of WordPress API with same syntax for arguments into your posts, pages, or widgets content. functionsCapacitor will insert function result into your content as HTML output.

(*) see Supported functions or conditional tags.


Three methods to use WordPress API functions :

Method by shortcode tag

Insert a tag into your content like [fct function_name="parameter1=value&parameter2=value"].

One shortcode tag can request several functions, input [fct function_name1="arguments" function_name2="arguments"].

Method with a widget

Add a functionsCapacitor widget, select a function, input function parameters like "parameter1=value&parameter2=value" (without quotes).

Optional: choose a supported conditional function to decide where to display your widget.

Method by custom fields

Set a custom field name with function name and put function arguments into custom field value like "parameter1=value&parameter2=value" (without quotes).
