---

## Files Created/Modified

### 1. editmachine.asp (NEW)
**Location:** `/home/camp/projects/windows/shopdb/editmachine.asp`

**Purpose:** Professional tabbed form for editing existing machines

**Features:**
- **5-tab layout** matching addmachine.asp (Basic Info, Network, Relationships, Compliance, Location)
- **Pre-filled form fields** with existing machine data
- **Same UI/UX** as addmachine.asp for consistency
- **Nested entity creation** capability (add new models, vendors, etc. while editing)
- **Read-only machine number** (cannot be changed)
- **Interactive map picker** for location updates
- **Responsive Bootstrap design** with theme support

**Data Loaded:**
- Machine details from `machines` table with JOINs
- Up to 3 network interfaces from `communications` table
- Controlling PC from `machinerelationships` table
- Dualpath machine from `machinerelationships` table
- Compliance data from `compliance` table
- Location coordinates

**Security:**
- Parameterized queries throughout
- machineid validation
- Redirects to displaymachines.asp if machine not found
- HTML encoding on all output

---

### 2. savemachineedit.asp (NEW)
**Location:** `/home/camp/projects/windows/shopdb/savemachineedit.asp`

**Purpose:** Backend handler for processing machine edit form submissions

**Operations Performed:**

1. **Validates Inputs**
   - machineid (required from hidden field)
   - All form fields (same validation as savemachine_direct.asp)
   - Checks machine exists before updating

2. **Handles Nested Entity Creation**
   - New business units
   - New models (with vendors, machine types, functional accounts)
   - New third-party vendors

3. **Updates Machine Table**
   - Updates: modelid, businessunitid, alias, machinenotes, mapleft, maptop
   - Does NOT update machinenumber (readonly)
   - Uses parameterized UPDATE query

4. **Updates Network Communications**
   - Deletes old communications: `DELETE FROM communications WHERE machineid = ?`
   - Inserts new communications for ip1/mac1, ip2/mac2, ip3/mac3
   - Sets isprimary=1 for Interface 1

5. **Updates Machine Relationships**
   - Deletes old relationships: `DELETE FROM machinerelationships WHERE (machineid = ? OR related_machineid = ?)`
   - Inserts new controlling PC relationship (one-way)
   - Inserts new dualpath relationships (bidirectional)

6. **Updates Compliance Data**
   - Checks if compliance record exists
   - If exists: UPDATE compliance SET ...
   - If not exists: INSERT INTO compliance ...
   - Handles third-party vendor creation

7. **Redirects**
   - Success: `displaymachine.asp?machineid=XXX`
   - Error: Shows error message with "Go back" link

**Security:**
- All queries use parameterized commands
- Input validation on all fields
- Error handling with proper user feedback

---

### 3. displaymachine.asp (MODIFIED)
**Location:** `/home/camp/projects/windows/shopdb/displaymachine.asp`

**Changes:**
- **Line 156**: Changed "Edit" tab to link to new `editmachine.asp` page
  - Now a styled button with gradient background
  - Direct link instead of tab
  - Icon changed to `zmdi-edit`
- **Lines 604-913**: Commented out old inline edit form
  - Preserved for reference but not active
  - Users now redirected to dedicated edit page

**Before:**
```asp
<li class="nav-item">
    <a href="javascript:void();" data-target="#edit" data-toggle="pill" class="nav-link">
        <i class="icon-note"></i> <span class="hidden-xs">Edit</span>
    </a>
</li>
```

**After:**
```asp
<li class="nav-item">
    <a href="./editmachine.asp?machineid=<%=Server.HTMLEncode(machineid)%>"
       class="nav-link"
       style="background: linear-gradient(45deg, #667eea 0%, #764ba2 100%); color: white;">
        <i class="zmdi zmdi-edit"></i> <span class="hidden-xs">Edit Machine</span>
    </a>
</li>
```

## User Workflow

### Editing a Machine:

1. **Navigate to machine**: Go to `displaymachine.asp?machineid=XXX`
2. **Click "Edit Machine"**: Styled button in top navigation tabs
3. **Redirected to**: `editmachine.asp?machineid=XXX`
4. **Edit form loads** with all existing data pre-filled across 5 tabs:
   - **Basic Info**: Machine number (readonly), model, business unit, alias, notes
   - **Network**: Up to 3 network interfaces (IP/MAC addresses)
   - **Relationships**: Controlling PC, dualpath/redundant machine
   - **Compliance**: Third-party management, vendor, OT asset, DoD type
   - **Location**: Map coordinates with visual picker
5. **Make changes** in any tab
6. **Add new entities** if needed (models, vendors, etc.)
7. **Click "Update Equipment"**
8. **Form submits** to `savemachineedit.asp`
9. **Data validated and saved**
10. **Redirected back** to `displaymachine.asp?machineid=XXX`

- Can create new vendors while editing machine
- Can create new business units while editing machine
- Can create new third-party vendors while editing machine
- All using same inline expandable sections as add form

### 4. Network Interface Management
- Edit up to 3 network interfaces
- Clear labeling (Primary, Optional)
- IP and MAC address validation
- Delete by leaving fields blank

### 5. Relationship Management

- Required fields checked before processing
- machineid validated and verified to exist

### SQL Injection Prevention
- **100% parameterized queries** throughout both files
- No string concatenation in SQL
- Uses `ADODB.Command` with typed parameters
- Example:
```asp
Set cmd = Server.CreateObject("ADODB.Command")
cmd.ActiveConnection = objConn
cmd.CommandText = "UPDATE machines SET modelid = ? WHERE machineid = ?"
cmd.Parameters.Append cmd.CreateParameter("@modelid", 3, 1, , CLng(modelid))
cmd.Parameters.Append cmd.CreateParameter("@machineid", 3, 1, , CLng(machineid))
cmd.Execute
```

### Output Encoding
- All user data passed through `Server.HTMLEncode()`
- Prevents XSS attacks
- Applied to all displayed values

### Error Handling
- Graceful error messages
- "Go back" links on errors
- No sensitive data exposed in errors
- Database connection always closed

## Known Limitations

### 1. Communication Editing Strategy
- Uses DELETE then INSERT approach
- Does not preserve comid values
- Cannot edit individual interfaces (all or nothing)
- **Future enhancement**: Allow editing specific interfaces without deleting all

### 2. Relationship Editing Strategy
- Uses DELETE then INSERT approach
- Does not preserve relationshipid values
- Cannot view relationship history
- **Future enhancement**: Add relationship history tracking

### 3. No Multi-Interface Management
- Can only add/edit up to 3 interfaces via form
- Additional interfaces require database access
- **Future enhancement**: Dynamic interface addition

### 4. File Naming Inconsistency
- Old file: `editmacine.asp` (typo)
- New file: `editmachine.asp` (correct spelling)
- Both exist for compatibility
- **Future enhancement**: Migrate all references and remove typo file

---

## File Dependencies

### editmachine.asp requires:
- `./includes/header.asp` - Page header and metadata
- `./includes/sql.asp` - Database connection
- `./leaflet/leaflet.css` - Map styling
- `./leaflet/leaflet.js` - Map functionality
- `assets/js/jquery.min.js` - jQuery library
- `assets/js/bootstrap.min.js` - Bootstrap framework
- Theme CSS files

### savemachineedit.asp requires:
- `./includes/sql.asp` - Database connection
- Valid POST data from editmachine.asp form

### displaymachine.asp requires:
- Access to editmachine.asp for Edit button link

## Migration from Old Edit System

### Old System (Inline Edit Tab):
- Embedded in displaymachine.asp
- Limited fields
- No Phase 2 data support
- Form posted to `editmacine.asp` (typo)
- Cramped UI in single tab

### New System (Dedicated Edit Page):
- Separate `editmachine.asp` page
- Full Phase 2 data support
- 5-tab organized layout
- Form posts to `savemachineedit.asp`
- Professional, spacious UI

### Migration Steps Taken:
1. ✅ Created new editmachine.asp with full Phase 2 support
2. ✅ Created new savemachineedit.asp handler
3. ✅ Updated displaymachine.asp Edit button to link to new page
4. ✅ Commented out old inline edit form (preserved for reference)
5. ⏳ Old `editmacine.asp` still exists (preserved for legacy compatibility)

---

## Troubleshooting

### Edit button doesn't work:
- Check machineid is valid in URL
- Verify editmachine.asp file exists
- Check file permissions

### Form doesn't load data:
- Check machineid parameter is passed correctly
- Verify machine exists in database
- Check database connection in sql.asp
- Review browser console for JavaScript errors

### Data doesn't save:
- Check savemachineedit.asp exists
- Verify form action points to correct file
- Check for validation errors in form submission
- Review database connection

### Map doesn't load:
- Verify leaflet.js and leaflet.css are accessible
- Check sitemap2025-dark.png and sitemap2025-light.png exist in ./images/
- Review browser console for JavaScript errors

### Relationships not saving:
- Verify relationship types exist in relationshiptypes table
- Check machinerelationships table for foreign key constraints
- Ensure related machines exist and have valid IDs
