WHOIS Extended for WHMCS Печать

The Problem

WHMCS shows "unavailable" for taken domains. That's it. No WHOIS data. No additional information. Red X. Dead end.

What Happens Without WHOIS Info

Standard WHMCS domain search:

Customer enters domain → Already taken → Red "Unavailable" message → Nothing else.

No information shown:

• Who owns it?
• When does it expire?
• Is it actually in use?
• Are nameservers configured?
• Contact information?
• Registration date?

Customer questions:

• "Maybe I can buy it from owner?"
• "When does it expire?"
• "Is this a typo squat?"
• "Should I try contacting them?"
• "Is it even active?"

Your support gets tickets:

• "Can you find out who owns this?"
• "When can I register it?"
• "Is there WHOIS info?"
• "Help me contact the owner"

What actually happens:

• Customer opens new tab
• Goes to who.is or whois.com
• Looks up domain there
• Sees competitor ads
• Maybe doesn't come back

Result: Lost context. Friction. Support load. Potential lost sale.

Failed Workarounds

Tell customers to use external WHOIS:

• Unprofessional
• They leave your site
• Competitors advertise on WHOIS sites
• Lost momentum
• Support burden explaining how

Custom development:

• WHOIS protocol integration
• Server connections
• Parsing different TLD formats
• Error handling
• Maintenance burden
• Expensive

Ignore the problem:

• Support tickets increase
• Lost sales when they don't return
• Unprofessional appearance

None solve it properly. External tools break the flow. Custom work costs too much.

The Solution

WHOIS Extended adds a "WHOIS" button next to unavailable domains. Click it → full WHOIS data in modal. Instant information. No leaving your site.

How It Works

On domain search page:

Customer searches domain → WHMCS checks availability

If available:

• Green checkmark
• Add to cart
• Standard behavior

If unavailable:

• Red X (standard)
• NEW: "WHOIS" button appears
• Click button → modal opens
• Full WHOIS data displayed

Modal shows:

• Domain name
• Registration date
• Expiration date
• Registrar
• Registrant information
• Administrative contact
• Technical contact
• Nameservers
• Domain status

Modal features:

• Clean, professional design
• Customizable styling
• Mobile responsive
• Close button
• Overlay background
• Fast loading

Customer flow:

1. Searches domain
2. Sees unavailable
3. Clicks WHOIS button
4. Reads WHOIS data
5. Decides next action
6. Closes modal
7. Tries alternative domain
8. Stays on your site

No external sites. No lost momentum.

Real Use Cases

Scenario 1: Expired Domain

Customer wants `businessname.com`:

Without WHOIS Extended:

• Shows unavailable
• Customer gives up
• Tries competitor
• Lost sale

With WHOIS Extended:

• Shows unavailable
• Clicks WHOIS
• Sees: Expired 3 months ago
• Sets reminder
• Monitors for availability
• Comes back to register
• Sale happens

Scenario 2: Typosquatter

Customer searches `yourbussiness.com` (typo):

Standard WHMCS:

• Unavailable
• "Why is my domain taken?"

With module:

• Clicks WHOIS
• Sees registrant: Domain parking service
• Realizes typo
• Searches correct spelling
• Finds available
• Registers correct domain

Scenario 3: Contact Owner

Customer wants specific domain:

Without info:

• Opens who.is
• Looks up manually
• Finds owner email
• Never returns to your site
• Lost customer

With module:

• Clicks WHOIS
• Sees registrant email
• Makes note
• Continues browsing alternatives
• Registers backup domain
• Still your customer

Scenario 4: Domain Research

Customer comparing multiple domains:

Standard experience:

• Checks domain 1: Unavailable
• Opens external WHOIS
• Checks domain 2: Unavailable
• Opens another tab
• Juggling multiple sites
• Abandons

WHOIS Extended:

• Check domain 1 → WHOIS modal → note info → close
• Check domain 2 → WHOIS modal → note info → close
• Check domain 3 → available → register
• All on your site

Scenario 5: Support Prevention

Customer sees unavailable domain:

Without module:

• Opens support ticket: "Can you check WHOIS for domain X?"
• Agent manually looks it up
• Responds with info
• Time wasted
• Support cost

With module:

• Customer clicks WHOIS
• Gets info instantly
• No ticket opened
• Support time saved

Troubleshooting

WHOIS button not appearing:

• Check module activated
• Verify license valid
• Confirm domain actually unavailable
• Review browser console for JavaScript errors
• Clear WHMCS cache

Modal won't open:

• JavaScript conflict with other modules
• Check browser console
• Disable other modules temporarily
• Test in different browser
• Check custom CSS conflicts

No WHOIS data shown:

• Domain registry blocking queries
• Rate limit hit (5-minute cache helps)
• WHOIS server timeout
• Check PHP socket functions enabled
• Firewall blocking port 43

Styling issues:

• Theme CSS conflicts
• Clear browser cache
• Check custom CSS syntax
• Test with default styling first
• Inspect element to find conflicts

Privacy-protected domains:

• Module shows proxy service info
• This is normal behavior
• Real owner info hidden by design
• Contact via registrar's proxy system

Language not displaying:

• Check WHMCS language setting
• Verify language file exists
• Clear template cache
• Check file permissions

High latency:

• WHOIS servers can be slow
• Some TLDs respond slower
• Caching reduces repeat queries
• Consider different registrar WHOIS server
• Check network connectivity
