+# Discharge Summary HTML Editor Fix
+
+## Problem
+After converting textarea controls to HTML editors (TinyMCE/similar) in the discharge form, saved discharge summaries were not appearing in the generated PDF.
+
+## Root Cause
+The `normalizeRichText()` function at line 1591 in `Ipd_discharge.php` was stripping ALL HTML tags using `strip_tags()`. This was designed for plain textarea input, but when HTML editors save formatted content with `<p>`, `<b>`, `<div>`, `<ul>`, etc., all the markup was being removed, leaving empty or malformed content.
+
+## Affected Fields
+- Presenting Complaints (complaint_remark)
+- Final Diagnosis (diagnosis_remark)  
+- Course in Hospital (course_remark)
+- Summary of Key Investigations (inhos_remark)
+- Other/Systemic Examinations (systemic exam text)
+- Other Examinations/Provisional Diagnosis (other_exam_text)
+
+## Solution
+Modified the following methods in `app/Controllers/Ipd_discharge.php`:
+
+### 1. Enhanced `normalizeRichText()` (line 1591)
+- Detects if content contains HTML tags from HTML editor
+- **If HTML detected**: Preserves HTML structure, only cleans whitespace
+- **If plain text**: Uses original logic (strip tags, convert to plain text)
+- Backward compatible with existing plain textarea fields
+
+### 2. 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. Open discharge form: `/Ipd_discharge/ipd_select/1007170`
+2. Verify HTML editor content is saved correctly
+3. Preview discharge PDF
+4. Check that formatted content (bold, lists, paragraphs) appears correctly
+5. Test with both HTML editor and plain textarea fields (backward compatibility)
+
+## Backward Compatibility
+✅ Existing plain textarea fields continue to work
+✅ HTML editor fields now render correctly
+✅ No database changes required
+✅ Automatic detection of content type (HTML vs plain text)
+
+## Security
+- HTML editor content is NOT escaped (assumes HTML editor provides safe content)
+- Plain text content continues to be escaped with `esc()` function
+- No XSS risk if HTML editor properly sanitizes input
