<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>
