Added `renderRichText()` (new method after normalizeRichText) +- Detects HTML vs plain text content +- **If HTML**: Returns content as-is for HTML rendering +- **If plain text**: Applies `esc()` and `nl2br()` for safe output + +### 3. Updated rendering methods +- `buildNarrativeSection()`: Changed `nl2br(esc($remark))` to `$this->renderRichText($remark)` +- Systemic exam section: Changed `nl2br(esc($value))` to `$this->renderRichText($value)` +- Other exam section: Changed `nl2br(esc($otherExamText))` to `$this->renderRichText($otherExamText)` +- Key investigations section: Changed `nl2br(esc($inhosRemark))` to `$this->renderRichText($inhosRemark)` + +## Changes Made +``` +File: app/Controllers/Ipd_discharge.php +- Line ~1591: Enhanced normalizeRichText() to preserve HTML +- Line ~1625: Added new renderRichText() helper method +- Line ~1768: Updated buildNarrativeSection() to use renderRichText() +- Line ~1932: Updated systemic exam rendering to use renderRichText() +- Line ~2094: Updated other exam rendering to use renderRichText() +- Line ~2113: Updated key investigations rendering to use renderRichText() +``` + +## Testing +1.
