LOGIC TITLE These are songs that are currently in
BOTH Bill and NOT Bass Guitar Categories.
[alphabuild category_name="x-bill-chase XOR bass-guitar-night"]
Key Changes in Version 3.0:
1. New Category Parser Class (AlphaBuildCategoryParser)
Parses category strings with conditional operators
Supports all the operators you specified
Handles both single and dual category operations
2. Supported Conditional Operators:
OR/UNION: live-baritone OR draft-baritone - Returns posts in either category
AND: live-baritone AND nearly-ready - Returns posts in both categories
XOR: live-baritone XOR live-tenor - Returns posts in first category but not second (A minus B)
NOT: NOT live-baritone - Returns posts not in the specified category
NOR: live-baritone NOR draft-baritone - Returns posts in neither category
NAND: live-baritone NAND draft-baritone - Returns posts in either category but not both
LEFT JOIN: live-baritone LEFT JOIN draft-baritone - Posts from first category excluding those in second
RIGHT JOIN: live-baritone RIGHT JOIN draft-baritone - Posts from second category excluding those in first
3. Usage Examples:
// Union of two categories
[alphabuild category_name="live-baritone OR draft-baritone"]
// Intersection of two categories
[alphabuild category_name="live-baritone AND nearly-ready"]
// Exclude a category
[alphabuild category_name="live-baritone XOR live-tenor"]
// Posts not in category
[alphabuild category_name="NOT live-baritone"]
4. Backward Compatibility:
Single category names still work: [alphabuild category_name="live-baritone"]
All existing parameters remain functional
Version 2.0 shortcodes will continue to work
5. Implementation Details:
Case-insensitive operator parsing
Proper escaping and sanitization
Efficient post filtering using WordPress query methods
Maintains alphabetical grouping after conditional filtering
The plugin now handles all the logical operations you specified, allowing complex category filtering while maintaining the original alphabetical navigation interface. Each conditional operator performs the exact set operations you described in your specifications.
THIS IS EVERYTHING ELSE.
Special characters are used to put things into a specific group. - - [ xyz-ihs snippet="first-letter"]
