<h1>CodeIgniter URLs</h1> |
|
60 |
||
61 |
<p>By default, URLs in CodeIgniter are designed to be search-engine and human friendly. Rather than using the standard "query string" |
|
62 |
approach to URLs that is synonymous with dynamic systems, CodeIgniter uses a <strong>segment-based</strong> approach:</p> |
|
63 |
||
64 |
<code>example.com/<var>news</var>/<dfn>article</dfn>/<samp>my_article</samp></code> |
|
65 |
||
66 |
<p class="important"><strong>Note:</strong> Query string URLs can be optionally enabled, as described below.</p> |
|
67 |
||
68 |
<h2>URI Segments</h2> |
|
69 |
||
70 |
<p>The segments in the URL, in following with the Model-View-Controller approach, usually represent:</p> |
|
71 |
||
72 |
<code>example.com/<var>class</var>/<dfn>function</dfn>/<samp>ID</samp></code> |
|
73 |
||
74 |
<ol> |
|
75 |
<li>The first segment represents the controller <strong>class</strong> that should be invoked.</li> |
|
76 |
<li>The second segment represents the class <strong>function</strong>, or method, that should be called.</li> |
|
77 |
<li>The third, and any additional segments, represent the ID and any variables that will be passed to the controller.</li> |
|
78 |
</ol> |
|
79 |
||
80 |
<p>The <a href="../libraries/uri.html">URI Class</a> and the <a href="../helpers/url_helper.html">URL Helper</a> |
|
81 |
contain functions that make it easy to work with your URI data. In addition, your URLs can be remapped using the |
|
82 |
<a href="routing.html">URI Routing</a> feature for more flexibility.</p> |
|
83 |
||
84 |
||
85 |
||
86 |
<h2>Removing the index.php file</h2> |
|
87 |
||
88 |
<p>By default, the <strong>index.php</strong> file will be included in your URLs:</p> |
|
89 |
||
90 |
<code>example.com/<var>index.php</var>/news/article/my_article</code> |
|
91 |
||
92 |
<p>You can easily remove this file by using a .htaccess file with some simple rules. Here is an example |
|
93 |
of such a file, using the "negative" method in which everything is redirected except the specified items:</p> |
|
94 |
||
95 |
<code>RewriteEngine on<br /> |
|
96 |
RewriteCond $1 !^(index\.php|images|robots\.txt)<br /> |
|
97 |
RewriteRule ^(.*)$ /index.php/$1 [L]</code> |
|
98 |
||
99 |
<p>In the above example, any HTTP request other than those for index.php, images, and robots.txt is treated as |
|
100 |
a request for your index.php file.</p> |
|
101 |
||
102 |
||
103 |
<h2>Adding a URL Suffix</h2> |
|
104 |
||
105 |
<p>In your <dfn>config/config.php</dfn> file you can specify a suffix that will be added to all URLs generated |
|
106 |
by CodeIgniter. For example, if a URL is this:</p> |
|
107 |
||
108 |
<code>example.com/index.php/products/view/shoes</code> |
|
109 |
||
110 |
<p>You can optionally add a suffix, like <kbd>.html</kbd>, making the page appear to be of a certain type:</p> |
|
111 |
||
112 |
<code>example.com/index.php/products/view/shoes.html</code> |
|
113 |
||
114 |
||
115 |
<h2>Enabling Query Strings</h2> |
|
116 |
||
117 |
<p>In some cases you might prefer to use query strings URLs:</p> |
|
118 |
||
119 |
<code>index.php?c=products&m=view&id=345</code> |
|
120 |
||
121 |
<p>CodeIgniter optionally supports this capability, which can be enabled in your <dfn>application/config.php</dfn> file. If you |
|
122 |
open your config file you'll see these items:</p> |
|
123 |
||
124 |
<code>$config['enable_query_strings'] = FALSE;<br /> |
|
125 |
$config['controller_trigger'] = 'c';<br /> |
|
126 |
$config['function_trigger'] = 'm';</code> |
|
127 |
||
128 |
<p>If you change "enable_query_strings" to TRUE this feature will become active. Your controllers and functions will then |
|
129 |
be accessible using the "trigger" words you've set to invoke your controllers and methods:</p> |
|
130 |
||
131 |
<code>index.php?c=controller&m=method</code> |
|
132 |
||
133 |
<p class="important"><strong>Please note:</strong> If you are using query strings you will have to build your own URLs, rather than utilizing |
|
134 |
the URL helpers (and other helpers that generate URLs, like some of the form helpers) as these are designed to work with |
|
135 |
segment based URLs.</p> |
