<h1>Scaffolding</h1>
 | 
						|
 | 
						|
<p class="important">Scaffolding has been deprecated from CodeIgniter as of 1.6.0.</p>
 | 
						|
 | 
						|
<p>CodeIgniter's Scaffolding feature provides a fast and very convenient way to add, edit, or delete information in your database
 | 
						|
during development.</p>
 | 
						|
 | 
						|
<p class="important"><strong>Very Important:</strong>  Scaffolding is intended for development use only.  It provides very little
 | 
						|
security other than a "secret" word, so anyone who has access to your CodeIgniter site can potentially edit or delete your information.
 | 
						|
If you use scaffolding make sure you disable it immediately after you are through using it.  DO NOT leave it enabled on a live site.
 | 
						|
And please, set a secret word before you use it.</p>
 | 
						|
 | 
						|
<h2>Why would someone use scaffolding?</h2>
 | 
						|
 | 
						|
<p>Here's a typical scenario:  You create a new database table during development and you'd like a quick way to insert some data
 | 
						|
into it to work with.  Without scaffolding your choices are either to write some inserts using the command line or to use a
 | 
						|
database management tool like phpMyAdmin.  With CodeIgniter's scaffolding feature you can quickly add some data using its browser
 | 
						|
interface.  And when you are through using the data you can easily delete it.</p>
 | 
						|
 | 
						|
<h2>Setting a Secret Word</h2>
 | 
						|
 | 
						|
<p>Before enabling scaffolding please take a moment to set a secret word.  This word, when encountered in your URL,
 | 
						|
will launch the scaffolding interface, so please pick something obscure that no one is likely to guess.</p>
 | 
						|
 | 
						|
<p>To set a secret word, open your <kbd>application/config/routes.php</kbd> file and look for this item:</p>
 | 
						|
 | 
						|
<code>$route['scaffolding_trigger'] = '';</code>
 | 
						|
 | 
						|
<p>Once you've found it add your own unique word.</p>
 | 
						|
 | 
						|
<p class="important"><strong>Note:</strong> The scaffolding word can <strong>not</strong> start with an underscore.</p>
 | 
						|
 | 
						|
 | 
						|
<h2>Enabling Scaffolding</h2>
 | 
						|
 | 
						|
<p>Note: The information on this page assumes you already know how <a href="controllers.html">controllers</a> work, and that you have
 | 
						|
a working one available.  It also assumes you have configured CodeIgniter to auto-connect to your <a href="../database/index.html">database</a>.
 | 
						|
If not, the information here won't be very relevant, so you are encouraged to go through those sections first.
 | 
						|
Lastly, it assumes you understand what a class constructor is.  If not, read the last section of the <a href="controllers.html">controllers</a>
 | 
						|
page.</p>
 | 
						|
 | 
						|
<p>To enable scaffolding you will initialize it in your constructor like this:</p>
 | 
						|
 | 
						|
<code>
 | 
						|
<?php<br />
 | 
						|
class Blog extends Controller {<br />
 | 
						|
<br />
 | 
						|
       function Blog()<br />
 | 
						|
       {<br />
 | 
						|
            parent::Controller();<br /><br />
 | 
						|
            <samp>$this->load->scaffolding(</samp><kbd>'table_name'</kbd>);<br />
 | 
						|
       }<br />
 | 
						|
}<br />
 | 
						|
?></code>
 | 
						|
 | 
						|
<p>Where <kbd>table_name</kbd> is the name of the table (table, not database) you wish to work with.</p>
 | 
						|
 | 
						|
<p>Once you've initialized scaffolding, you will access it with this URL prototype:</p>
 | 
						|
 | 
						|
<code>example.com/index.php/<var>class</var>/<dfn>secret_word</dfn>/</code>
 | 
						|
 | 
						|
<p>For example, using a controller named <var>Blog</var>, and <dfn>abracadabra</dfn> as the secret word,
 | 
						|
you would access scaffolding like this:</p>
 | 
						|
 | 
						|
<code>example.com/index.php/<var>blog</var>/<dfn>abracadabra</dfn>/</code>
 | 
						|
 | 
						|
<p>The scaffolding interface should be self-explanatory.  You can add, edit or delete records.</p>
 | 
						|
 | 
						|
 | 
						|
<h2>A Final Note:</h2>
 | 
						|
 | 
						|
<p>The scaffolding feature will only work with tables that contain a primary key, as this is information is needed to perform the various
 | 
						|
database functions.</p>
