PHP Codeigniter 3.X Intellisense

Lightweight IntelliSense for CodeIgniter 3 projects in VS Code.

This extension is designed for CodeIgniter 3.x projects. It does not support CodeIgniter 4.x.

The extension starts when you open a PHP file in a workspace that contains a CodeIgniter system folder. It parses your configured application folders and provides completions, symbols, hover information, and navigation for common CodeIgniter patterns.

Features

Code Completion

• Completes models, libraries, and selected CodeIgniter system classes.
• Supports $this->, $CI->, and $this->CI->db style access.
• Supports method chaining for the db class.
• Completes constants and static variables after ClassName::.
• Supports variables declared in models, such as $this->mymodel->some_variable.
• Refreshes model discovery with the CI: refresh Model command.

Library files are parsed when you open a file that loads them, such as:

$this->load->library('foo');

Document Symbols

Use VS Code document symbols to list methods in the current PHP file. If another PHP extension already provides symbols and you see duplicates, set CI.ignoreSymbols to true.

Go To Definition

Go to definitions for models, libraries, methods, constants, and linked view files.

View-file navigation works for patterns such as:

$this->load->view('path');

Hover

Hover over supported methods to see parsed documentation.

Requirements

• VS Code 1.90.0 or newer.
• A CodeIgniter 3 workspace with a system folder.
• PHP files opened with VS Code's PHP language mode.

Extension Settings

• CI.ignoreSymbols: Disable this extension's document symbols when another PHP extension already provides them.
• CI.model: Auto-loaded models.
• CI.library: Auto-loaded libraries.
• CI.other: Extra PHP files to parse, such as system/core/Common.php.
• CI.system: Path to the CodeIgniter system folder.
• CI.app: Path to the CodeIgniter application folder.
• CI.viewFilesFormat: View file extension, such as php, tpl, or twig.

Known Limitations

• The parser is based on regular expressions, so unusual PHP structure may not be recognized.
• Multiple classes in one file may not work reliably.
• If a library and model share the same name, the model may take precedence.
• For duplicate symbols with PHP IntelliSense or Intelephense, set CI.ignoreSymbols to true.

Attribution

This extension is based on the original PHP intellisense for codeigniter VS Code extension by Small, originally published at smallp/vscode-ci.

This version modernizes the build and runtime dependencies for newer VS Code versions while preserving the original CodeIgniter 3 language features.
