How to create automatic subdomains from a form?

I am developing a large system, which already serves almost 30 companies in the state and some more are to join.

The system is accessed by companies from this url:

  • meudomínio.com.br/business1
  • meudomínio.com.br/loading2
  • meudomínio.com.br/lending 3

I’d like to know how to do the "Automatic subdomain" which is kind of like this here:

Subdomínio automático por formulário

I enter the name of the company and it passes to access the system from company1.meudomínio.com.br

    This is an Apache configuration. I don’t see how a system that runs under Apache itself could change a configuration of it. My suggestion would be to keep the domains saved in some bank and use a cron to search for the domains created and create them in Apache settings.

  • Can you confirm which web server you are using? As @rodrigorigotti said, the ideal would be to schedule a task that changes the server settings, but how to do this depends on the server used, (and depending on the case, also the operating system).

  • Use cPanel, follow an ss of the server settings: link

    First you need to have a database with the list of subdomains. Then just create a *wildcard subdomain .dominio.com.br pointing to a file testa_subdominio.php. When the user type meulogin.dominio.com.br, the server calls testa_subdominio.php which connects to the BD and loads the page to login "meulogin" or error 404, if the login does not exist or is invalid.

  • If you are using Cpanel, you can use this Cpanel library that allows you to create subdomains by passing PHP parameters. https://github.com/CpanelInc/xmlapi-php

Allowing apache to create folders... of dynamics this is the best because internal paths are fixed alone, without impact to php for example... http://httpd.apache.org/docs/2.2/vhosts/mass.html#simple

But I already used the text file method, it had no graphical interface, to administer, but the client could upload a text file to ftp in which he put the domain and the root folder and apache went up the site in the act, according to the apache site: 

RewriteEngine on

RewriteMap lowercase int:tolower

# define the map file
RewriteMap vhost txt:/www/conf/vhost.map

# deal with aliases as above
RewriteCond %{REQUEST_URI} !^/icons/
RewriteCond %{REQUEST_URI} !^/cgi-bin/
RewriteCond ${lowercase:%{SERVER_NAME}} ^(.+)$
# this does the file-based remap
RewriteCond ${vhost:%1} ^(/.*)$
RewriteRule ^/(.*)$ %1/docs/$1

RewriteCond %{REQUEST_URI} ^/cgi-bin/
RewriteCond ${lowercase:%{SERVER_NAME}} ^(.+)$
RewriteCond ${vhost:%1} ^(/.*)$
RewriteRule ^/(.*)$ %1/cgi-bin/$1

  • Thanks @Brenozan. Just a question with this: this map file "vhost.mp" I have to create? What file template?

    yes you create... in practice you can also use mdb or mysql (DO NOT USE!), just need to meet the map compatibilities of rewrite http://httpd.apache.org/docs/current/rewrite/rewritemap.html#dbm. I really suggest you use the simple.. the others give a headache with the paths and security issues of the applications within them..
