Wondering about the post meta your theme and/or plugins might be creating?
Want to find the name of a specific post meta key?
Need some help debugging your post meta?
The JSM Show Post Meta plugin displays all post meta (aka custom fields) keys and their unserialized values in a metabox at the bottom of post editing pages.
There are no plugin settings — simply install and activate the plugin.
If you need to create an array of store hours (for example), the following function can generate an associative array of values quickly, with the hours formatted and stepped (every hour, 30 mins, etc.) as you wish.
I’ve seen similar functions using DateTime(), but we’re already working with timestamps, so there’s really no need.
I often want to output an array for debugging purposes, but using var_dump() or print_r() on an array that includes true / false values and class objects can be problematic — false values appear empty, and class objects can include too much information. I wrote the following recursive static method (presented here as a function) to pre-filter an array for readability when using print_r() or var_dump().
