changelog

Registration and content creation were failing due to MySQL strict mode
requiring all NOT NULL fields without DEFAULT values to be specified.

Core changes:

1. User registration (modules/account/index.php):
• Add user_block, user_warnings, user_field, user_network to INSERT
* Email activation registration
* Social network registration

2. Admin user creation (admin/index.php):
• Add user_block, user_warnings, user_field to admin INSERT

3. Help module (modules/help/admin/index.php):
• Add field column to help INSERT

4. News module (modules/news/index.php):
• Add associated column to news INSERT

5. Database schema (setup/sql/table*.sql):
• Use CREATE TABLE IF NOT EXISTS for idempotent migrations

Benefits:
• Registration now works with MySQL strict mode
• Consistent INSERT queries across modules
• Idempotent database migrations

Technical notes:
• All new fields initialized with empty strings
• Compatible with existing database schema

Improve code formatting and template structure in the lite theme
for better readability and maintainability.

Core changes:

1. Template files (templates/lite/):
• index.php: Normalize indentation to spaces
• login.html: Update login form template
• login-logged.html: Update logged-in state template
• login-without.html: Update guest state template

Benefits:
• Consistent code formatting
• Improved template readability
• Better maintainability

Technical notes:
• No functional changes
• Indentation standardized to 4 spaces

Clean up obsolete image module files that are no longer needed.

Core changes:

1. Removed files (modules/image/):
• .htaccess
• index.php

Benefits:
• Cleaner module structure
• Remove unused code from repository

Technical notes:
• Image handling now managed elsewhere in the system

Improve template conditional rendering API by using a more descriptive key name
that clearly indicates the purpose of boolean flags in templates.

Core changes:

1. Template engine (core/template.php):
• Rename array key 'flag' to 'if_flag'
• Maintain full backward compatibility with existing templates

2. Documentation (docs/TEMPLATES.md):
• Update all code examples to use new 'if_flag' key
• Clarify conditional rendering usage

Benefits:
• More intuitive and self-documenting API
• Clear distinction between variables and conditional flags
• Consistent naming convention with 'if:' template syntax

Technical notes:
• No breaking changes to template syntax
• Only affects PHP-side array key naming

Standardize language file naming across all modules using ISO 639-1 codes
for better internationalization support and consistency.

Core changes:

1. Language file renaming (all modules):
• lang-english.php → en.php
• lang-german.php → de.php
• lang-french.php → fr.php
• lang-russian.php → ru.php
• lang-ukrainian.php → uk.php
• lang-polish.php → pl.php

2. Affected modules:
• account, auto_links, changelog, clients, contact
• faq, files, forum, help, jokes
• links, media, money, news, order, pages

Benefits:
• ISO 639-1 standard compliance
• Shorter, cleaner filenames
• Consistent naming convention across codebase

Technical notes:
• Both admin and frontend language files updated
• No content changes, only file renaming

Remove spaces from conditional template tags for consistency
with actual template parser behavior.

Core changes:

1. Template syntax (docs/TEMPLATES.md):
• Change {% if FLAG %} to {%if FLAG%}
• Change {% else %} to {%else%}
• Change {% endif %} to {%endif%}
• Change {% elseif %} to {%elseif%}
• Updated all 6 practical examples

Benefits:
• Consistent syntax across documentation and code
• Matches actual template parser implementation

Add new 📚 Documentation section with links to all project documentation
files including the new TEMPLATES.md guide.

Core changes:

1. Documentation index (README.md):
• Add table with all documentation files
• Link to TEMPLATES.md, CONTRIBUTING.md, UPGRADING.md, SECURITY.md, CODE_OF_CONDUCT.md
• Brief descriptions for each document

Benefits:
• Better discoverability of project documentation
• Centralized documentation index
• Easy navigation for contributors and users

Implements {% if FLAG %} ... {% else %} ... {% endif %} conditional
blocks for templates, enabling dynamic content display based on flags
passed from PHP code.

Core changes:

1. Template conditional rendering (core/template.php):
• Add setTemplateIf() function for processing conditional blocks
* Supports nested IF blocks
* Boolean normalization for string 'true'/'false' values
* Undefined flags default to false
* Pure string-based parsing (no eval)
• Update setTemplateBasic() to support 'if_flag' parameter
• Update setTemplateBlock() to support 'if_flag' parameter
• Fix typo in comment header

Benefits:
• Enables dynamic content display (login/logout, admin links, etc.)
• Safe template conditionals without eval()
• Consistent flag handling across template functions
• Improved code documentation

Technical notes:
• Flags must match pattern [a-zA-Z0-9_]+
• No support for elseif, logical operators, or comparisons
• Performance optimized with early return for templates without {%

Complete overhaul of project documentation with consistent formatting,
version information, and GitHub alert syntax for better readability.

Core changes:

CONTRIBUTING.md, README.md, SECURITY.md, UPGRADING.md):
- Added "Last updated: January 2026" headers
- Added copyright footers
- Consistent formatting throughout

2. Template documentation created (docs/TEMPLATES.md):

- 6 practical examples with PHP code
- Security & performance best practices
- Migration guide from legacy tpl_* functions

3. README.md enhanced:
- Detailed modernization status (12 admin modules listed)
- Version history table with PHP compatibility
- Security statistics (2106+ SQL, 269+ input points)

4. UPGRADING.md expanded:
- Migration checklist for custom modules
- Removed/renamed files documentation
- Breaking changes with code examples

5. SECURITY.md improved:
- Modules secured table
- Deprecated functions table
- Known issues for 6.2.x

Benefits:
