• 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

    <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:

<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;">

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:

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
