strict warning: Non-static method view – Drupal warning messages – Drupal / PHP 5.4

by

As E_STRICT is now the part of E_ALL from PHP 5.4 ( Reference http://us.php.net/ChangeLog-5.php#5.4.0 ), this warning can pop-up on most systems with Drupal + PHP 5.4 because usually E_ALL is set as the default error reporting for PHP. Also PHP 5.4 is not officially supported by Druapl. Using a supported PHP version also can resolve issues with Drupal views ( Refer https://drupal.org/requirements/php for Druapl’s PHP requirements )

Anyway we need to use PHP 5.4 for Druapl and to avoid such warnings to display in the website. Disabling E_STRICT in php.ini didn’t help, because Druapl defines its own error reporting function. So we had to make the following changes to the Druapl core files, as per the information collected from their forum.

1. Open /includes/bootstrap.inc

In the beginning of function drupal_set_message and  below “if ($message) { ” line, put the following  code

How to check a website in a remote server before DNS change

by

In all migrations, we may wish to check the domain’s functionality and fix any errors preset  to make the dns change smoother and perfect. So just thought to add this in our blog too 🙂

Some control panel offer site preview, especially Plesk using which we can take a look on domain  hosted in that domain. But in others like cPanel, Directadmin and those without any control panels, we may need to check this using  local hosts file or by changing the A record on a temporary basis.

Best method is to check websites using your local “hosts” file in your PC / Laptop. Below is the steps using which one can test a website hosted in a remote server without changing the name server.

For Windows

1.  Locate the hosts file in your computer. Typically it is in one of the following locations:

Windows NT/2000/XP/2003/Vista/7   —     C:\windows\system32\drivers\etc\hosts
Windows 95/98/Me                                         —     C:\windows\hosts
