CodeIgniter Smiley Helper Configuration

CodeIgniter Smiley Helper Configuration | Generated by AI

Overview

This is a PHP configuration file from the CodeIgniter web framework, specifically for its emoticons/smileys helper. CodeIgniter is a PHP MVC framework for building web apps. This file defines a set of smiley/emoticon mappings used by the framework’s smiley_helper to automatically replace text-based emoticons (like :-)) with HTML <img> tags that display corresponding GIF images.

The file ensures direct access is blocked via defined('BASEPATH') OR exit('No direct script access allowed');, a security measure in CodeIgniter to prevent unauthorized direct script execution.

Key Components

Purpose: Converts plain text emoticons in user-generated content (e.g., forum posts or comments) into visual images for a better user experience.
Data Structure: $smileys is a PHP associative array with formal structure:
```
$smileys = array(
    'smiley_code' => array('image_file', 'width', 'height', 'alt_text'),
    // ...
);
```
- smiley_code: The text pattern to match (e.g., :-), :lol:, >:().
- image_file: Name of the GIF image in the smiley directory (defaults to application/views/smileys/ in CodeIgniter).
- width/height: Dimensions in pixels for the <img> tag (all are '19' here, indicating 19x19px GIFs).
- alt_text: Alternative text for accessibility/screen readers, describing the emotion.
Usage in CodeIgniter: Load the helper with $this->load->helper('smiley');, then call functions like parse_smileys($text) on strings containing emoticon codes. This replaces codes with <img> tags, e.g.:
- Input: I'm happy :)
  Output: I'm happy <img src="http://example.com/smileys/smile.gif" width="19" height="19" alt="smile">

Breakdown of Entries

The array includes 40+ mappings grouped by emotion type. Most images are 19x19px GIFs. Here’s a summarized view (with examples):

`:-)`, `:)`	grin.gif, smile.gif	grin, smile	Positive grins and smiles.
`:lol:`, `:cheese:`	lol.gif, cheese.gif	LOL, cheese	Laughing/thumbs up, cheesy grin.
`;-)`, `;)`	wink.gif	wink	Winking.
`:smirk:`, `:roll:`	smirk.gif, rolleyes.gif	smirk, rolleyes	Sarcasm/sage nodding.
`:-S`, `:wow:`, `:bug:`	confused.gif, surprise.gif, bigsurprise.gif	confused, surprised, big surprise	Confusion/surprise.
`:-P`, `%-P`, `;-P`, `:P`	tongue_laugh.gif, etc.	tongue laugh, etc.	Tongue-out variants (laughing, wink, raspberry).
`:blank:`, `:long:`, `:ohh:`, `:grrr:`, `:gulp:`, `8-/`	Various	blank stare, long face, ohh, grrr, gulp, oh oh	Neutral or annoyed faces.
`:down:`, `:red:`, `:sick:`, `:shut:`	Various	downer, red face, sick, shut eye	Sad, embarrassed, sick.

`:vampire:`, `:snake:`	vampire.gif, snake.gif	vampire, snake	Themed emoticons.
`:exclaim:`, `:question:`	exclaim.gif, question.gif	exclaim, question	Punctuation equivalents (!, ?).

Extension and Customization

Adding Smileys: Append new entries, e.g., ':fire:' => array('fire.gif', '19', '19', 'fire');.
Changing Images: Update file names if replacing GIFs with PNGs/JPGs (adjust width/height accordingly).
Directory: Ensure images exist in CodeIgniter’s smiley path.
Limitations: All images here are the same size; real implementations might vary. This array only defines mappings—replacement logic is in the helper itself.
