59
60<p class="important"><strong>Note:</strong> The instructions on this page assume you are running version 1.4.1. If you
61have not upgraded to that version please do so first.</p>
62
63<p>Before performing an update you should take your site offline by replacing the index.php file with a static one.</p>
64
65
66
67<h2>Step 1: Update your CodeIgniter files</h2>
68
69<p>Replace these files and directories in your "system" folder with the new versions:</p>
70
71<ul>
72
73<li><dfn>application/config/user_agents.php</dfn> (new file for 1.5)</li>
74<li><dfn>application/config/smileys.php</dfn> (new file for 1.5)</li>
75<li><dfn>codeigniter/</dfn></li>
76<li><dfn>database/</dfn> (new folder for 1.5. Replaces the "drivers" folder)</li>
77<li><dfn>helpers/</dfn></li>
78<li><dfn>language/</dfn></li>
79<li><dfn>libraries/</dfn></li>
80<li><dfn>scaffolding/</dfn></li>
81</ul>
82
83<p class="important"><strong>Note:</strong> If you have any custom developed files in these folders please make copies of them first.</p>
84
85
86<h2>Step 2: Update your database.php file</h2>
87
88<p>Open your <dfn>application/config/database.php</dfn> file and add these new items:</p>
89
90<pre>
91$db['default']['cache_on'] = FALSE;
92$db['default']['cachedir'] = '';
93</pre>
94
95
96
97<h2>Step 3: Update your config.php file</h2>
98
99<p>Open your <dfn>application/config/config.php</dfn> file and <kbd>ADD</kbd> these new items:</p>
100
101<pre>
102/*
103|--------------------------------------------------------------------------
104| Class Extension Prefix
105|--------------------------------------------------------------------------
106|
107| This item allows you to set the filename/classname prefix when extending
108| native libraries. For more information please see the user guide:
109|
110| http://codeigniter.com/user_guide/general/core_classes.html
111| http://codeigniter.com/user_guide/general/creating_libraries.html
112|
113*/
114$config['subclass_prefix'] = 'MY_';
115
116/*
117|--------------------------------------------------------------------------
118| Rewrite PHP Short Tags
119|--------------------------------------------------------------------------
120|
121| If your PHP installation does not have short tag support enabled CI
122| can rewrite the tags on-the-fly, enabling you to utilize that syntax
123| in your view files. Options are TRUE or FALSE (boolean)
124|
125*/
126$config['rewrite_short_tags'] = FALSE;
127</pre>
128
129<p>In that same file <kbd>REMOVE</kbd> this item:</p>
130
131
132<pre>
133/*
134|--------------------------------------------------------------------------
135| Enable/Disable Error Logging
136|--------------------------------------------------------------------------
137|
138| If you would like errors or debug messages logged set this variable to
139| TRUE (boolean). Note: You must set the file permissions on the "logs" folder
140| such that it is writable.
141|
142*/
143$config['log_errors'] = FALSE;
144</pre>
145
146<p>Error logging is now disabled simply by setting the threshold to zero.</p>
147
148
149
150<h2>Step 4: Update your main index.php file</h2>
151
152<p>If you are running a stock <dfn>index.php</dfn> file simply replace your version with the new one.</p>
153
154<p>If your <dfn>index.php</dfn> file has internal modifications, please add your modifications to the new file and use it.</p>
155
156
157
158<h2>Step 5: Update your user guide</h2>
159
160<p>Please also replace your local copy of the user guide with the new version.</p>
