debug_log()

Usage

PHP

nebula()->debug_log($message, $filepath)

Parameters

$message
(Optional) (String) The message to append to the log file
Default: None

$filepath
(Optional) (String) The filepath to the log file
Default: get_stylesheet_directory() . '/nebula_log.log'

Parameter Notes

The message is not technically required, but is strongly recommended.

If no filepath is provided, it will be logged to “nebula_log.log” located in the child theme directory (or theme directory if not using a child theme).

Note: This function will create the file if it does not exist, but it will not create directories if they do not yet exist.

Request or provide clarification »

Examples

This will create a nebula_log.log file in the child theme directory.

PHP

nebula()->debug_log('This is a test')

Write to a custom file within a directory (make sure the directory already exists as this function does not create new directories).

PHP

nebula()->debug_log('This is a test', get_stylesheet_directory() . '/debug/test.log')

Additional Notes

The format of each line in the log is:

[timestamp] message (on file)

Example:

[Saturday, April 19, 2020 – 10:51:51am] This is a test. (on https://nebula.gearside.com/documentation/)
