Drupal: Status report problem: HTTP request status fails

Some of you may have encountered this problem in some cases. In "Status Report" page, accidentally appears the error below:

HTTP request status   Fails
Your system or network configuration does not allow Drupal to access web pages, resulting in reduced functionality. This could be due to your webserver configuration or PHP settings, and should be resolved in order to download information about available updates, fetch aggregator feeds, sign in via OpenID, or use other network-dependent services.

What I did, was to recheck that my webserver had access to internet. Of course it had! The problem exists mostly when there is no information to resolve the domain name used with the local ip address of the webserver. This means that an error occurs in the entries of the DNS server.

In cases where DNS server is not existant(ex. local testing environment) all you have to do is inform the /etc/hosts file. For example if you use the domain http://www.example.local/ and your local ip address is 192.168.1.2 then all you have to do is create/edit a entry like this in /etc/hosts:

#/etc/hosts file
127.0.0.1 example
192.168.1.2 example.local www.example.local

or if you have multiple domains assigned to the same computer use the example below:
#/etc/hosts file
127.0.0.1 example
192.168.1.2 domain1.local www.domain1.local domain2.local www.domain2.local example.local www.example.local

PS: This problem is discussed in drupal.org.

Configure drupal_http_request() on the fly

The drupal_http_request() function supports connections using a proxy. You can configure a global proxy to use for all drupal_http_request() callbacks from the settings.php file of your website/installation by filling the following lines with the proper information:For those of you preferring a UI, then HTTP proxy module is for you.But what if you only want to use a proxy in some cases; like a custom module? In that case you will need the following function(modify accordingly):Now all you have to do is Call <?php _MYMODULE_change_proxy(); ?>.Do your drupal_http_request() calls.Call <?php _MYMODULE_change_proxy(TRUE); ?> to reset your previous settings.

Drupal: Allow registrations through Invite or Referral modules only

The Invite module provides invitations from existing users to their contacts. The Referral module, in contrary, creates a special URL for each existing user, which can be found in each user's profile, and allows new user registration. Even though, these two modules seem to provide the same functionality, they don't (and they shouldn't). Invite module, provides a mechanism for a site administrator to limit new registrations to "Invitations only". Referral module doesn't provide any of this functionality. Some users have requested the Invite module and Referral module to join in one module. Until now, there isn't anything to that direction. Wouldn't it be great though if there was a solution to limit drupal registration to referral or invitation only? Copy the functions below to a refinvite.module file in your sites→all→modules→refinvite folder and enable the module. Then go to http://<your-address-here>/admin/user/settings and enable the new …

Send mass email to certain users using VBO

Views Bulk Operations uses the built-in actions to act upon nodes, users, entities etc. Among these actions is our ability to send emails to users. If you try to use this action though you will encounter a small but serious problem. You are asked for an email address to send your message. You might say "but I have selected the users I want this message to reach. Why should I input an address again?". Don't get overwhelmed. What this field expects is not an address but a token. Specially this token [user-email]. If the website is intended for you, then you might say that's not such a problem to write this token down again and again. But if the manager of the website is bound to be the client or if you just want to spend less time writing things down, you might prefer to use a custom hook_form_alter() callback to set a default value. It could be done in both theme and module environment so suit yourself. Just add the following in your module or theme.
