Andrey Andreevec902162012-07-02 15:57:34 +0300519- Fixed a bug - ``CI_DB_pdo_driver::num_rows()`` was not returning properly value with SELECT queries, cause it was relying on ``PDOStatement::rowCount()``.
520- Fixed a bug (#1059) - ``CI_Image_lib::clear()`` was not correctly clearing all necessary object properties, namely width and height.

619Version 2.0.3
620=============
621
622Release Date: August 20, 2011
623
624- Security
625
626 - An improvement was made to the MySQL and MySQLi drivers to prevent
627 exposing a potential vector for SQL injection on sites using
628 multi-byte character sets in the database client connection.
629 An incompatibility in PHP versions < 5.2.3 and MySQL < 5.0.7 with
630 *mysql_set_charset()* creates a situation where using multi-byte
631 character sets on these environments may potentially expose a SQL
632 injection attack vector. Latin-1, UTF-8, and other "low ASCII"
633 character sets are unaffected on all environments.
634
635 If you are running or considering running a multi-byte character
636 set for your database connection, please pay close attention to
637 the server environment you are deploying on to ensure you are not
638 vulnerable.
639

652 Thanks to epallerols for the patch.
653 - Added "application/x-csv" to mimes.php.
Timothy Warren01b56bc2011-10-10 10:45:45 -0400654 - Fixed a bug where :doc:`Email library <libraries/email>`
Derek Jones8ede1a22011-10-05 13:34:52 -0500655 attachments with a "." in the name would using invalid MIME-types.
Derek Jones8ede1a22011-10-05 13:34:52 -0500656

662 protection field when the form's action is internal and is set to
663 the post method. (Reactor #165)

665 helper <helpers/inflector_helper>` to support considerably
666 more words.

678 library <libraries/loader>` to retrieve global vars set with
679 $this->load->view() and $this->load->vars().
680 - Changed $this->db->having() to insert quotes using escape() rather
681 than escape_str().
682

703 of all items in the cart instead of your total count.
704- Fixed a bug where not setting 'null' when adding fields in db_forge
705 for mysql and mysqli drivers would default to NULL instead of NOT
706 NULL as the docs suggest.
707- Fixed a bug where using $this->db->select_max(),
708 $this->db->select_min(), etc could throw notices. Thanks to w43l for
709 the patch.
710- Replace checks for STDIN with php_sapi_name() == 'cli' which on the
711 whole is more reliable. This should get parameters in crontab
712 working.

831 - Scaffolding, having been deprecated for a number of versions, has
832 been removed.
833 - Plugins have been removed, in favor of Helpers. The CAPTCHA plugin
834 has been converted to a Helper and
835 :doc:`documented <./helpers/captcha_helper>`. The JavaScript
836 calendar plugin was removed due to the ready availability of great

851 controller sub-directory can be specified when running _GET
852 strings instead of URI segments.
853 - Added ability to set "Package" paths - specific paths where the
854 Loader and Config classes should try to look first for a requested
855 file. This allows distribution of sub-applications with their own
856 libraries, models, config files, etc. in a single "package"
857 directory. See the :doc:`Loader class <libraries/loader>`
858 documentation for more details.

Derek Jones8ede1a22011-10-05 13:34:52 -0500865 now be set without an extension, the extension will be taken from
866 the uploaded file instead of the given name.
867 - In :doc:`Database Forge <database/forge>` the name can be omitted

895 that one can specify the object to look for requested methods,
896 instead of assuming it is in the $CI superobject.
897 - Added "is_object" into the list of unit tests capable of being
898 run.
899 - Table library will generate an empty cell with a blank string, or
900 NULL value.
901 - Added ability to set tag attributes for individual cells in the
902 Table library
903 - Added a parse_string() method to the :doc:`Parser
904 Class <libraries/parser>`.

1353 - Added a new :doc:`Form Validation
1354 Class <libraries/form_validation>`. It simplifies setting
1355 rules and field names, supports arrays as field names, allows
1356 groups of validation rules to be saved in a config file, and adds
1357 some helper functions for use in view files. **Please note that
1358 the old Validation class is now deprecated**. We will leave it in
1359 the library folder for some time so that existing applications
1360 that use it will not break, but you are encouraged to migrate to
1361 the new version.
1362 - Updated the :doc:`Sessions class <libraries/sessions>` so that
1363 any custom data being saved gets stored to a database rather than
1364 the session cookie (assuming you are using a database to store
1365 session data), permitting much more data to be saved.
1366 - Added the ability to store libraries in subdirectories within
1367 either the main "libraries" or the local application "libraries"
1368 folder. Please see the :doc:`Loader class <libraries/loader>` for
1369 more info.

1371 names when you use $this->load->library(). Please see the :doc:`Loader
1372 class <libraries/loader>` for more info.

1374 class <general/profiling>` and support for multiple database
1375 connections.

1385 :doc:`File Upload Class <libraries/file_uploading>`.
1386 - Added set_status_header() function to :doc:`Output
1387 class <libraries/output>`.

2283- Added "is_numeric" to validation, which uses the native PHP
2284 is_numeric function.
2285- Improved the URI handler to make it more reliable when the
2286 $config['uri_protocol'] item is set to AUTO.
2287- Moved most of the functions in the Controller class into the Loader
2288 class, allowing fewer reserved function names for controllers when
2289 running under PHP 5.
2290- Updated the DB Result class to return an empty array when
2291 $query->result() doesn't produce a result.
2292- Updated the input->cookie() and input->post() functions in :doc:`Input
2293 Class <./libraries/input>` to permit arrays contained cookies
2294 that are arrays to be run through the XSS filter.
2295- Documented three functions from the Validation
2296 class that were missing from the user
2297 guide: set_select(), set_radio(), and set_checkbox().
2298- Fixed a bug in the Email class related to SMTP Helo data.
2299- Fixed a bug in the word wrapping helper and function in the email
2300 class.
2301- Fixed a bug in the validation class.

2303 block level elements in paragraph tags.
2304- Fixed a problem in the form_prep() function that was double encoding
2305 entities.
2306- Fixed a bug that affects some versions of PHP when output buffering
2307 is nested.
2308- Fixed a bug that caused CI to stop working when the PHP magic
2309 __get() or __set() functions were used within models or
2310 controllers.
2311- Fixed a pagination bug that was permitting negative values in the
2312 URL.
2313- Fixed an oversight in which the Loader class was not allowed to be
2314 extended.
2315- Changed _get_config() to get_config() since the function is not a
2316 private one.
2317- **Deprecated "init" folder**. Initialization happens automatically
2318 now. :doc:`Please see documentation <./general/creating_libraries>`.
2319- **Deprecated** $this->db->field_names() USE
2320 $this->db->list_fields()
2321- **Deprecated** the $config['log_errors'] item from the config.php
2322 file. Instead, $config['log_threshold'] can be set to "0" to turn it

2325Version 1.4.1
2326=============
2327
2328Release Date: September 21, 2006
2329
2330- Added a new feature that passes URI segments directly to your
2331 function calls as parameters. See the
2332 :doc:`Controllers <general/controllers>` page for more info.
2333- Added support for a function named _output(), which when used in
2334 your controllers will received the final rendered output from the
2335 output class. More info in the :doc:`Controllers <general/controllers>`
2336 page.
2337- Added several new functions in the :doc:`URI
2338 Class <./libraries/uri>` to let you retrieve and manipulate URI
2339 segments that have been re-routed using the :doc:`URI
2340 Routing <general/routing>` feature. Previously, the URI class did not
2341 permit you to access any re-routed URI segments, but now it does.
2342- Added :doc:`$this->output->set_header() <./libraries/output>`
2343 function, which allows you to set server headers.
2344- Updated plugins, helpers, and language classes to allow your
2345 application folder to contain its own plugins, helpers, and language
2346 folders. Previously they were always treated as global for your
2347 entire installation. If your application folder contains any of these
2348 resources they will be used *instead* the global ones.
2349- Added :doc:`Inflector helper <./helpers/inflector_helper>`.
2350- Added element() function in the :doc:`array
2351 helper <./helpers/array_helper>`.
2352- Added RAND() to active record orderby() function.
2353- Added delete_cookie() and get_cookie() to :doc:`Cookie
2354 helper <./helpers/cookie_helper>`, even though the input class
2355 has a cookie fetching function.
2356- Added Oracle database driver (still undergoing testing so it might
2357 have some bugs).
2358- Added the ability to combine pseudo-variables and php variables in
2359 the template parser class.
2360- Added output compression option to the config file.
2361- Removed the is_numeric test from the db->escape() function.
2362- Fixed a MySQLi bug that was causing error messages not to contain
2363 proper error data.
2364- Fixed a bug in the email class which was causing it to ignore
2365 explicitly set alternative headers.
2366- Fixed a bug that was causing a PHP error when the Exceptions class
2367 was called within the get_config() function since it was causing
2368 problems.
2369- Fixed an oversight in the cookie helper in which the config file
2370 cookie settings were not being honored.
2371- Fixed an oversight in the upload class. An item mentioned in the 1.4
2372 changelog was missing.
2373- Added some code to allow email attachments to be reset when sending
2374 batches of email.
2375- Deprecated the application/scripts folder. It will continue to work
2376 for legacy users, but it is recommended that you create your own
2377 :doc:`libraries <./general/libraries>` or
2378 :doc:`models <./general/models>` instead. It was originally added
2379 before CI had user libraries or models, but it's not needed anymore.
2380- Deprecated the $autoload['core'] item from the autoload.php file.
2381 Instead, please now use: $autoload['libraries']
2382- Deprecated the following database functions:
2383 $this->db->smart_escape_str() and $this->db->fields().

2390- Added :doc:`Hooks <./general/hooks>` feature, enabling you to tap
2391 into and modify the inner workings of the framework without hacking
2392 the core files.
2393- Added the ability to organize controller files :doc:`into
2394 sub-folders <general/controllers>`. Kudos to Marco for
2395 `suggesting <http://codeigniter.com/forums/viewthread/627/>`_ this
2396 (and the next two) feature.
kenjis087a7a82011-10-20 20:08:47 +09002397- Added regular expressions support for :doc:`routing

2407 helper.
2408- Added support for changing the port number in the :doc:`Postgres
2409 driver <./database/configuration>`.
2410- Moved the list of "allowed URI characters" out of the Router class
2411 and into the config file.
2412- Moved the MIME type array out of the Upload class and into its own

Derek Jones8ede1a22011-10-05 13:34:52 -05002414- Updated the Upload class to allow the upload field name to be set
2415 when calling :doc:`do_upload() <./libraries/file_uploading>`.
2416- Updated the :doc:`Config Library <./libraries/config>` to be able to
2417 load config files silently, and to be able to assign config files to
2418 their own index (to avoid collisions if you use multiple config
2419 files).
2420- Updated the URI Protocol code to allow more options so that URLs will
2421 work more reliably in different environments.
2422- Updated the form_open() helper to allow the GET method to be used.
2423- Updated the MySQLi execute() function with some code to help prevent
2424 lost connection errors.
2425- Updated the SQLite Driver to check for object support before

2438 that it's a private function.
2439- Deprecated the hash() function due to a naming conflict with a native
2440 PHP function with the same name. Please use dohash() instead.
2441- Fixed an bug that was preventing the input class from unsetting GET
2442 variables.
2443- Fixed a router bug that was making it too greedy when matching end
2444 segments.
2445- Fixed a bug that was preventing multiple discrete database calls.
2446- Fixed a bug in which loading a language file was producing a "file
2447 contains no data" message.
2448- Fixed a session bug caused by the XSS Filtering feature inadvertently
2449 changing the case of certain words.
2450- Fixed some missing prefixes when using the database prefix feature.
2451- Fixed a typo in the Calendar class (cal_november).
2452- Fixed a bug in the form_checkbox() helper.

2477
2478Release Date: June 1, 2006
2479
2480- Models do **not** connect automatically to the database as of this
2481 version. :doc:`More info here <./general/models>`.
2482- Updated the Sessions class to utilize the active record class when
2483 running session related queries. Previously the queries assumed MySQL
2484 syntax.
2485- Updated alternator() function to re-initialize when called with no
2486 arguments, allowing multiple calls.
2487- Fixed a bug in the active record "having" function.
2488- Fixed a problem in the validation class which was making checkboxes

2506Release Date: April 17, 2006
2507
2508- Changed the behavior of the validation class such that if a
2509 "required" rule is NOT explicitly stated for a field then all other
2510 tests get ignored.
2511- Fixed a bug in the Controller class that was causing it to look in
2512 the local "init" folder instead of the main system one.
2513- Fixed a bug in the init_pagination file. The $config item was not
2514 being set correctly.

2522
2523Release Date: April 11, 2006

2525- Added a :doc:`Unit Testing Library <./libraries/unit_testing>`.
2526- Added the ability to pass objects to the **insert()** and
2527 **update()** database functions. This feature enables you to (among
2528 other things) use your :doc:`Model class <./general/models>`
2529 variables to run queries with. See the Models page for details.
2530- Added the ability to pass objects to the :doc:`view loading
2531 function <./general/views>`: $this->load->view('my_view',
2532 $object);

Derek Jonesce79be02012-06-25 23:23:46 -07002536 class <./database/query_builder>`.
Derek Jones8ede1a22011-10-05 13:34:52 -05002537- Added language file for scaffolding and fixed a scaffolding bug that
2538 occurs when there are no rows in the specified table.
2539- Added :doc:`$this->db->last_query() <./database/queries>`, which
2540 allows you to view your last query that was run.
2541- Added a new mime type to the upload class for better compatibility.
2542- Changed how cache files are read to prevent PHP errors if the cache
2543 file contains an XML tag, which PHP wants to interpret as a short
2544 tag.
2545- Fixed a bug in a couple of the active record functions (where and
2546 orderby).
2547- Fixed a bug in the image library when realpath() returns false.

2552
2553Version 1.3
2554===========
2555
2556Release Date: April 3, 2006
2557
2558- Added support for :doc:`Models <general/models>`.
2559- Redesigned the database libraries to support additional RDBMs
2560 (Postgres, MySQLi, etc.).
Derek Jonesce79be02012-06-25 23:23:46 -07002561- Redesigned the :doc:`Active Record class <./database/query_builder>`
Derek Jones8ede1a22011-10-05 13:34:52 -05002562 to enable more varied types of queries with simpler syntax, and
2563 advanced features like JOINs.
2564- Added a feature to the database class that lets you run :doc:`custom
2565 function calls <./database/call_function>`.
2566- Added support for :doc:`private functions <general/controllers>` in your
2567 controllers. Any controller function name that starts with an
2568 underscore will not be served by a URI request.
2569- Added the ability to pass your own initialization parameters to your
2570 :doc:`custom core libraries <general/creating_libraries>` when using
2571 $this->load->library()
2572- Added support for running standard :doc:`query string URLs <general/urls>`.
2573 These can be optionally enabled in your config file.
2574- Added the ability to :doc:`specify a "suffix" <general/urls>`, which will be
2575 appended to your URLs. For example, you could add .html to your URLs,
2576 making them appear static. This feature is enabled in your config
2577 file.
2578- Added a new error template for use with native PHP errors.
2579- Added "alternator" function in the :doc:`string
2580 helpers <./helpers/string_helper>`.
2581- Removed slashing from the input class. After much debate we decided
2582 to kill this feature.
2583- Change the commenting style in the scripts to the PEAR standard so
2584 that IDEs and tools like phpDocumenter can harvest the comments.
2585- Added better class and function name-spacing to avoid collisions with
2586 user developed classes. All CodeIgniter classes are now prefixed with
2587 CI\_ and all controller methods are prefixed with _ci to avoid
2588 controller collisions. A list of reserved function names can be
2589 :doc:`found here <general/controllers>`.
2590- Redesigned how the "CI" super object is referenced, depending on
2591 whether PHP 4 or 5 is being run, since PHP 5 allows a more graceful
2592 way to manage objects that utilizes a bit less resources.
2593- Deprecated: $this->db->use_table() has been deprecated. Please read
Derek Jonesce79be02012-06-25 23:23:46 -07002594 the :doc:`Active Record <./database/query_builder>` page for
Derek Jones8ede1a22011-10-05 13:34:52 -05002595 information.
2596- Deprecated: $this->db->smart_escape_str() has been deprecated.
2597 Please use this instead: $this->db->escape()
2598- Fixed a bug in the exception handler which was preventing some PHP
2599 errors from showing up.
2600- Fixed a typo in the URI class. $this->total_segment() should be
2601 plural: $this->total_segments()
2602- Fixed some typos in the default calendar template
2603- Fixed some typos in the user guide

2608Release Date: March 21, 2006
2609
2610- Redesigned some internal aspects of the framework to resolve scoping
2611 problems that surfaced during the beta tests. The problem was most
2612 notable when instantiating classes in your constructors, particularly
2613 if those classes in turn did work in their constructors.
2614- Added a global function named
2615 :doc:`get_instance() <general/ancillary_classes>` allowing the main
2616 CodeIgniter object to be accessible throughout your own classes.
2617- Added new :doc:`File Helper <./helpers/file_helper>`:
2618 delete_files()
2619- Added new :doc:`URL Helpers <./helpers/url_helper>`: base_url(),
2620 index_page()
2621- Added the ability to create your own :doc:`core
2622 libraries <general/creating_libraries>` and store them in your local
2623 application directory.
2624- Added an overwrite option to the :doc:`Upload
2625 class <./libraries/file_uploading>`, enabling files to be
2626 overwritten rather than having the file name appended.
2627- Added Javascript Calendar plugin.
2628- Added search feature to user guide. Note: This is done using Google,
2629 which at the time of this writing has not crawled all the pages of
2630 the docs.
2631- Updated the parser class so that it allows tag pars within other tag
2632 pairs.
2633- Fixed a bug in the DB "where" function.
2634- Fixed a bug that was preventing custom config files to be
2635 auto-loaded.
