# Orthobaru - Medical Record System for Orthodontic Dental Clinic

## Unified Medical Record Viewing/Editing System

### Overview

This update unifies the medical record viewing and editing interfaces into a single file. Previously, we had separate files (`view.php` and `edit.php`) for viewing and editing medical records, which resulted in maintenance issues when making changes to the UI or functionality.

### Changes Made

1. **Unified Interface**:

   - `edit.php` now handles both viewing and editing of records
   - `view.php` is now just a redirect to `edit.php` with a view mode parameter

2. **View Mode Parameter**:

   - Added a URL parameter `mode=view` to indicate view-only mode
   - Example: `edit.php?id=123&mode=view` for viewing record with ID 123

3. **Conditional Display**:

   - Section files have been updated to show different UI elements based on the mode:
     - View mode: read-only fields with static text
     - Edit mode: input fields, select boxes, etc.

4. **Data Loading**:

   - Updated `data_loader.php` to use the mode parameter instead of checking the filename
   - In view mode, all sections' data is loaded at once for better performance

5. **Security**:
   - Added permission checks appropriate to each mode
   - Non-doctors are automatically redirected to view mode

### Advantages

1. **Easier Maintenance**: Only one file to update when making UI changes
2. **Consistent UI**: Same layout and styling for both viewing and editing
3. **Better Code Organization**: Reduced code duplication
4. **Simplified Navigation**: Users can switch between modes with a single click

### Implementation Details

- The `$isViewMode` flag is set based on the URL parameter: `$isViewMode = isset($_GET['mode']) && $_GET['mode'] === 'view';`
- Each section file uses this flag to determine what to display
- Form submission handlers only process data when not in view mode

### How to Use

- To view a record: `edit.php?id={recordId}&mode=view`
- To edit a record: `edit.php?id={recordId}`
- The navigation links and buttons have been updated to use these new URLs

### Important Notes

1. All links to `view.php` should be updated to use `edit.php` with the view mode parameter
2. Each section file should be updated to handle both modes
3. When creating new sections, be sure to include conditionals for both modes

### Sample Code Pattern

```php
<?php if ($isViewMode): ?>
    <!-- View mode display -->
    <p class="form-control-static"><?php echo htmlspecialchars($value); ?></p>
<?php else: ?>
    <!-- Edit mode input -->
    <input type="text" class="form-control" name="field_name" value="<?php echo htmlspecialchars($value); ?>">
<?php endif; ?>
```
