Upgrading from 3.1.2 to 3.1.3

+

Before performing an update you should take your site offline by +replacing the index.php file with a static one.

+
+

Step 1: Update your CodeIgniter files

+

Replace all files and directories in your system/ directory.

+
+

Note

+

If you have any custom developed files in these directories, +please make copies of them first.

+
+
+
+

Step 2: Remove usage of nice_date() helper (deprecation)

+

The Date Helper function nice_date() is +no longer useful since the introduction of PHP’s DateTime classes

+

You can replace it with the following:

+
DateTime::createFromFormat($input_format, $input_date)->format($desired_output_format);
+
+
+

Thus, nice_date() is now deprecated and scheduled for removal in +CodeIgniter 3.2+.

+
+

Note

+

The function is still available, but you’re strongly encouraged +to remove its usage sooner rather than later.

+
+
+
+

Step 3: Remove usage of $config[‘standardize_newlines’]

+

The Input Library would optionally replace +occurrences of rn, r, n in input data with whatever the PHP_EOL +value is on your system - if you’ve set $config['standardize_newlines'] +to TRUE in your application/config/config.php.

+

This functionality is now deprecated and scheduled for removal in +CodeIgniter 3.2.+.

+
+

Note

+

The functionality is still available, but you’re strongly +encouraged to remove its usage sooner rather than later.
