12.3.2. Subject Properties

A property simply defines what part of the subject you want. There are many properties that can be selected in Property select. The available properties are given below.

Important

Not all the properties are available for all the subjects. The plugin will display the properties that are suitable for the selected subject.

12.3.2.1. Value

This property uses the subject’s value directly. Selecting this is the same as not selecting a property at all.

12.3.2.2. Character length

This property counts the number of characters in the selected subject’s value.

Options

Treat as HTML?:	Check this if the subject’s value is HTML, and you want to work with the texts of the elements. If you do not check this in that case, then the HTML code will be considered as well.

12.3.2.3. Word length

This property counts the number of words in the selected subject’s value.

Options

12.3.2.4. Numeric value

This property parses the selected subject’s value to a number so that you can use the commands that can work with numbers. If the subject value is not numeric, this property will skip its value.

This is available for the request subject only. This retrieves the HTTP status code from the response of the request made to the target web page. For example, 404 is for not-found pages. Please note that the target web page might not be sending a standard status code. For example, instead of sending 404 response code for a not-found page, the target web page may choose to redirect the page to another, non-related page and send 200 response. Which status code the target site sends depends on the target site.

12.3.2.21. Error text

This is available for the Error subjects only. This retrieves the error’s text content. The text content includes the error message and the exception stack trace, if there was an exception that caused the error. Additionally, if there are any details about the error, they will be in the error text as well. The error text is actually the same text that is added to WordPress’s debug.log file by the plugin. So, you can check out your debug.log file to understand what is in the error text. Once you know what is in the error text, you can use this property to do certain things when a specific error occurs.

Here is an example error text, which is for an OpenAI API error:

WPCC (error): Completion cannot be retrieved. [Prompt: "Say hi"] (Details: Client error: `POST https://api.openai.com/v1/completions` resulted in a `401 Unauthorized` response:
