I have several posts where part of the displayed content will depend on several conditions.
I am thinking on creating a custom html tag. Then, before displaying the post content,
the conditions will be checked by running a script in the background . Finally the appropriate content will be displayed by replacing the tag with data retrieved from a database.
What is the best way to do this pre-processing with wordpress? Are they specific hooks allowing to get access to the post before displaying it?
example:
TEXT
custom html
TEXT
