58 <h1>Upgrading from
1.4.1 to
1.5.0</h1>
60 <p class=
"important"><strong>Note:
</strong> The instructions on this page assume you are running version
1.4.1. If you
61 have not upgraded to that version please do so first.
</p>
63 <p>Before performing an update you should take your site offline by replacing the index.php file with a static one.
</p>
67 <h2>Step
1: Update your CodeIgniter files
</h2>
69 <p>Replace these files and directories in your "system" folder with the new versions:
</p>
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>
83 <p class=
"important"><strong>Note:
</strong> If you have any custom developed files in these folders please make copies of them first.
</p>
86 <h2>Step
2: Update your database.php file
</h2>
88 <p>Open your
<dfn>application/config/database.php
</dfn> file and add these new items:
</p>
91 $db['default']['cache_on'] = FALSE;
92 $db['default']['cachedir'] = '';
97 <h2>Step
3: Update your config.php file
</h2>
99 <p>Open your
<dfn>application/config/config.php
</dfn> file and
<kbd>ADD
</kbd> these new items:
</p>
103 |--------------------------------------------------------------------------
104 | Class Extension Prefix
105 |--------------------------------------------------------------------------
107 | This item allows you to set the filename/classname prefix when extending
108 | native libraries. For more information please see the user guide:
110 | http://codeigniter.com/user_guide/general/core_classes.html
111 | http://codeigniter.com/user_guide/general/creating_libraries.html
114 $config['subclass_prefix'] = 'MY_';
117 |--------------------------------------------------------------------------
118 | Rewrite PHP Short Tags
119 |--------------------------------------------------------------------------
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)
126 $config['rewrite_short_tags'] = FALSE;
129 <p>In that same file
<kbd>REMOVE
</kbd> this item:
</p>
134 |--------------------------------------------------------------------------
135 | Enable/Disable Error Logging
136 |--------------------------------------------------------------------------
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.
143 $config['log_errors'] = FALSE;
146 <p>Error logging is now disabled simply by setting the threshold to zero.
</p>
150 <h2>Step
4: Update your main index.php file
</h2>
152 <p>If you are running a stock
<dfn>index.php
</dfn> file simply replace your version with the new one.
</p>
154 <p>If your
<dfn>index.php
</dfn> file has internal modifications, please add your modifications to the new file and use it.
</p>
158 <h2>Step
5: Update your user guide
</h2>
160 <p>Please also replace your local copy of the user guide with the new version.
