Implementing the new Password Hashing API from PHP 5.5 in DotKernel

In order to use the new Password Hashing functions , introduced in PHP 5.5 , and unify all password related functions , used for both admin and users, we did a major refactor of DotKernel codebase, in version 1.8.0 , starting from revision 799.

See more on that matter here

Better Unicode Support in MySQL 5.5 UTF8MB4

Beginning with version 5.5 of MySQL , utf8mb4 character set was introduced, in order to better support Unicode.
Further reading: MySQL and Unicode , also directly related to PHP

Sample dk.sql file, part of DotKernel framework, was updated in revision 793

Only one downside , is not possible to use anymore VARCHAR(255), as you will get the error:

#1071 - Specified KEY was too long; MAX KEY LENGTH IS 767 bytes

Explanation here ; so we use instead VARCHAR(150)

Now we should change the connection charset. In config/application.ini file, edit the below line :

database.params.charset = utf8mb4

Other changes that can be made in my.cnf file are all related to replacing the string utf8_* with utf8mb4_*

character_set_server=utf8mb4
collation_server=utf8mb4_general_ci
collation_server=utf8mb4_unicode_ci

Avoid routing through bootstrap of non existent files

In some cases you may encounter missing files: images, css or js files.
All those missing files are processed by the current bootstrap: index.php

If the session is set to regenerate on each request, as a normal security measure,
the currently logged user is logged off, because the session ID is different now.

To avoid this, below the following line

RewriteEngine On

add the line :

RewriteCond %{REQUEST_FILENAME} (\.gif|\.jpg|\.png|\.css|\.js)$ [OR]

Save and don’t forget to test.

Even though it’s a well known fact that real men do not test…
