Check if domain is already on the server!? help please

You can check it by running the following two commands from the shell:

grep username /etc/userdomains (For Username)

OR

grep domain.com /etc/userdomains (For Domain Name)

 

I don't think he means running php in cpanel - just checking if the [cpanel] user exists in a php script. A side note: cpanel does allow php scripts to run in the cpanel /usr/local/cpanel/base/frontend/skin directory.

The best option would be to keep track of the accounts in a database, separate of cpanel. You could update the database with the accounting module (described below)

Alternatives:

You could use the php accounting module to get a list of the accounts:
http://www.cpanel.net/remoteaccess-php.html
use the listaccts() function to get a 2-dimensional array of all the accounts with details like the domain. Then write your own function to check on them.


For these options, you may need to disable some php security to allow access to these files. I wouldn't recommend it, but it's an option.
Use php to scan the /etc/passwd file for the username. Read the contents of the file and search for the username string. Use php to scan the /var/named/ directory for the domain. Check if the file /var/named/$domain.db exists.

 

What's wrong? My response gives you two ways to do it.

 

Yeah, as I explained in my first post "Check if the file /var/named/$domain.db exists."

PHP:


$domain = "something.com";
if (file_exists("/var/named/$domain.db")){
   //  There is a DNS entry on this server.
}
else{
    // There is no DNS entry on this server
}



EDIT: The above checks for a domain. As I explained before, in order to check for a username, you would have to grep or use one of PHP's functions to scan /etc/password. If you don't know how to do this, pay someone to do it for you.

 

My thread on how to extend the remote access features may also come in useful: http://forums.cpanel.net/showthread.php?t=46362

This demonstrates the general process for integrating WHM/cPanel functionality into your own site, such as the ability to check if a given domain is taken.
