Hi

 

Nobody can help me with my Problem?

Give me some explain how to configure the lincensing addon.

 

Thanks

[sentq]

read this tutorial:

http://forum.whmcs.com/showthread.php?99354-How-to-guide-Configure-and-Setup-the-WHMCS-Licensing-Addon

[Lui2004]

Hi

 

I Have Read this but still the same Problem my Problem ist the licence key is invalid .

 

Do you have an Example for me?

 

Thanks

[sentq]

the check code example included with the addon files should be easy for any developer to embed in their code,

if you have issue with the addon module itself you may check the Activity Logs in WHMCS Admin Area for any error records!

[Lui2004]

What i muss Set here ?

 

$licensekey= ""

$localkey = ""

 

And where the will found my generated license?

 

Sorry for all this questions

[sentq]

first you need to pass both variables to the following function everytime:

yourprefix123_check_license($licensekey, $localkey='') function

 

$licensekey= ""

this is the License Key, your client will need to purchase it from your WHMCS client area, once they pay WHMCS will generate unique key for this purchase.

 

$localkey = ""

this is the Local Key,

How to get it?

* It will be automatically generated and returned as a result of running the function above.

 

Where to save it?

* you can save it in the software installed Database or .TXT file for example.

 

Why do I need it?

* this text contain all the information related to this use of license, like the installation path of this software, IP addresses, domain name, and new check date or expiry date for that license etc, all this information is encrypted.

* so each time the function above run, it will validate the information from this (Local Key) if all is OK it will return array of result including (License Status = Active, LocalKey = New Key to be saved for the next run, etc ), otherwise it will try to connect to your server to validate the license.

 

And where the will found my generated license?

Activate the Addon Module from Admin Area -> Setup -> Addon Modules -> License Manager

 

Sorry for all this questions

not a problem

[Lui2004]

Ok perfect

 

I have create a Table in database called keys and create into this table license_keys and local_key how to store now my localkey and licence key into this tables?

 

Yourprefix123_check_license($licensekey, $localkey=")function

 

Which Name i have to give Yourprefix123_check_license?

 

I Have call it: check_license($licensekey, $localkey=")function

 

 

I run check_license.php and I Got follow on my browser:

 

Array

(

[status] => invalid

[Massage] => domain invalid

[Remotecheck] => 1

)

 

License key is invalid

 

 

Thanks for helping me

 

Ps: i can write here only with Handy and not with my PC, why?

Edited November 29, 2015 by Lui2004

[sentq]

that's great, now you need to create/purchase a license key in your WHMCS installation to test it with this function

[Lui2004]

I Have purchase a licens but i get in Browser follow:

 

Array

(

[status] => Invalid

[Remotecheck => 1

)

 

 

In my database is no localkey or licensekey saved

 

I have this in my check_license.php

 

$licensekey = mysql_result(mysql_query("SELECT license_key FROM keys LIMIT 1"),0);

 

$localkey = mysql_result(mysql_query("SELECT local_key FROM key LIMIT 1"),0);

 

Do you have a how to or you can give a help to create the table key with the license_key and local_key field because i think i dont have Made it correctly

 

 

Thanks

[sentq]

in the following lines, do you have your WHMCS installation URL added?

function yourprefix123_check_license($licensekey, $localkey='') {

   // -----------------------------------
   //  -- Configuration Values --
   // -----------------------------------

   // Enter the url to your WHMCS installation here
   $whmcsurl = 'http://www.yourdomain.com/whmcs/';

 

check this tutorial I mentioned before, it cover all what you ask for:

http://markustenghamn.com/how-to-configure-and-setup-whmcs-licensing-addon-review-how-to

[Lui2004]

Can anybody Post the how to connect with database ?because their is not available

 

 

Thanks

[Sliffer21]

Try hardcoding the license key in your program and leaving the local key null. This will be a test without much work before you add it to a database. As for how to retrieve from a database just google "php retrieve data from a mysql database". I had an issue with the license check not working of our cyphers followed newer PCI recomended standards but doing away with being so strict on those solved our problem.

 

For the WHMCS domain in your check code are you making sure it is your WHMCS frontend area path? For example if WHMCS is installed in /public_html/whmcs your domain would be http://example.com/whmcs

Edited November 30, 2015 by Sliffer21

[Lui2004]

So now I have Insert the licens and I Got

Valid Domains, valid ips valid directory

 

But my Programm saß not valid licens

 

I am disperated

 

What i make wrong?

 

Thanks

[Sliffer21]

Ok so you have inserted the license key into the code (hardcoded it)?

 

Your WHMCS updates the license IP and directory fields?

 

But your still getting an invalid license correct?

[Lui2004]

Yes Thats correct

[Sliffer21]

OK what is your licensing addon log saying?

[Lui2004]

Licensing Manager:

1 active licenses

1 total licenses in database

 

Status message:

Invalid key -

Without licens Thats strange

 

Thanks

Edited November 30, 2015 by Lui2004

[Sliffer21]

Without seeing a handful of things I am not sure what the problem could be since obviously the licensing is working because it is updating the directory and IP. I would venture to open up a support ticket with technical support in your situation.

[Lui2004]

Hi

 

I Have in Internet a verify.php and I have try it and it Works only if i put the licens manually into this verify.php

 

I dont now if its ok if i Post this verify.php because the original is coded and this one From Internet is open but with this is verify.php my licens work.

But this code dont send me valid ip ,valid domain and valid directory

 

Why i can write into this thread only with M mobile Phone on my PC to reply thread is grey

 

Regards

[Sliffer21]

Chances are that verify.php file you found that is unencoded is being used for something bad such as pirated licensing or something of that nature. I am not aware of WHMCS ever releasing and unencoded one because that file is basically the core of the licensing addon. I wouldn't trust it but definitely report the link to where you found it to WHMCS's piracy department.

[Lui2004]

Oh **************** i will delete this file

I dont want to be a pirate

[Lui2004]

Hi

 

I Got some News about my Problem with licensing addon:

 

I execute the check_code.php and I Got follow on my browser :

 

Array

(

[status] => active

[Registeredname] => test test

=> my Email adress

[serviceid] => 6

[Productid] => 1

[Productname] => my Productname

[regdate] => 2015-12-02

[nextduedate] => 0000-00-00

[billingcycle] => Free Account

[validdomain] => my ip ,www

[Validip] => my ip

[Validdiractory] => /var/www/html/modules/servers/licensing

[Md5Hash] => generated hash

[checkdate] => 20151202

)

 

 

Why the code check the wrong directory?

 

What i doing wrong ?

 

Thanks

[Sliffer21]

In your check license function code there is a line at the top of the function:

   $whmcsurl = 'http://www.yourdomain.com/whmcs/';

 

Make sure that goes to your WHMCS installation such as https://example.com/whmcs/

(with the ending "/"), let me know if that helps.
