58 <h1>Upgrading from 1.2 to 1.3</h1>
60 <p class="important"><strong>Note:</strong> The instructions on this page assume you are running version 1.2. If you
61 have not upgraded to that version please do so first.</p>
64 <p>Before performing an update you should take your site offline by replacing the index.php file
65 with a static one.</p>
68 <h2>Step 1: Update your CodeIgniter files</h2>
70 <p>Replace the following directories in your "system" folder with the new versions:</p>
72 <p class="important"><strong>Note:</strong> If you have any custom developed files in these folders please make copies of them first.</p>
75 <li>application/<strong>models</strong>/ (new for 1.3)</li>
76 <li>codeigniter (new for 1.3)</li>
87 <h2>Step 2: Update your error files</h2>
89 <p>Version 1.3 contains two new error templates located in <dfn>application/errors</dfn>, and for naming consistency the other error templates have
92 <p>If you <strong>have not</strong> customized any of the error templates simply
93 replace this folder:</p>
96 <li>application/errors/</li>
99 <p>If you <strong>have</strong> customized your error templates, rename them as follows:</p>
103 <li>404.php = error_404.php</li>
104 <li>error.php = error_general.php</li>
105 <li>error_db.php (new)</li>
106 <li>error_php.php (new)</li>
110 <h2>Step 3: Update your index.php file</h2>
112 <p>Please open your main <dfn>index.php</dfn> file (located at your root). At the very bottom of the file, change this:</p>
114 <code>require_once BASEPATH.'libraries/Front_controller'.EXT;</code>
118 <code>require_once BASEPATH.'codeigniter/CodeIgniter'.EXT;</code>
121 <h2>Step 4: Update your config.php file</h2>
123 <p>Open your <dfn>application/config/config.php</dfn> file and add these new items:</p>
127 |------------------------------------------------
129 |------------------------------------------------
131 | This option allows you to add a suffix to all URLs.
132 | For example, if a URL is this:
134 | example.com/index.php/products/view/shoes
136 | You can optionally add a suffix, like ".html",
137 | making the page appear to be of a certain type:
139 | example.com/index.php/products/view/shoes.html
142 $config['url_suffix'] = "";
146 |------------------------------------------------
147 | Enable Query Strings
148 |------------------------------------------------
150 | By default CodeIgniter uses search-engine and
151 | human-friendly segment based URLs:
153 | example.com/who/what/where/
155 | You can optionally enable standard query string
158 | example.com?who=me&what=something&where=here
160 | Options are: TRUE or FALSE (boolean)
162 | The two other items let you set the query string "words"
163 | that will invoke your controllers and functions:
164 | example.com/index.php?c=controller&m=function
167 $config['enable_query_strings'] = FALSE;
168 $config['controller_trigger'] = 'c';
169 $config['function_trigger'] = 'm';
173 <h2>Step 5: Update your database.php file</h2>
175 <p>Open your <dfn>application/config/database.php</dfn> file and add these new items:</p>
178 $db['default']['dbprefix'] = "";
179 $db['default']['active_r'] = TRUE;
183 <h2>Step 6: Update your user guide</h2>
185 <p>Please also replace your local copy of the user guide with the new version.</p>
