<h1>CodeIgniter URLs<a class="headerlink" href="#codeigniter-urls" title="Permalink to this headline">¶</a></h1>
|
|||
|
|
<p>By default, URLs in CodeIgniter are designed to be search-engine and
|
|||
|
|
human friendly. Rather than using the standard “query string” approach
|
|||
|
|
to URLs that is synonymous with dynamic systems, CodeIgniter uses a
|
|||
|
|
<strong>segment-based</strong> approach:</p>
|
|||
|

<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nx">example</span><span class="o">.</span><span class="nx">com</span><span class="o">/</span><span class="nx">news</span><span class="o">/</span><span class="nx">article</span><span class="o">/</span><span class="nx">my_article</span>

<h2>URI Segments<a class="headerlink" href="#uri-segments" title="Permalink to this headline">¶</a></h2>
|

|
|
<p>The segments in the URL, in following with the Model-View-Controller
|
|||
|
|
approach, usually represent:</p>
|
|||

<ol class="arabic simple">
|

<li>The first segment represents the controller <strong>class</strong> that should be
|
|||
|
|
invoked.</li>
|
|||
|
|
<li>The second segment represents the class <strong>function</strong>, or method, that
|

should be called.</li>
|

|

<li>The third, and any additional segments, represent the ID and any

<h2>Removing the index.php file<a class="headerlink" href="#removing-the-index-php-file" title="Permalink to this headline">¶</a></h2>
|
|||
|
|
<p>By default, the <strong>index.php</strong> file will be included in your URLs:</p>
|
|||
|
|
<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nx">example</span><span class="o">.</span><span class="nx">com</span><span class="o">/</span><span class="nx">index</span><span class="o">.</span><span class="nx">php</span><span class="o">/</span><span class="nx">news</span><span class="o">/</span><span class="nx">article</span><span class="o">/</span><span class="nx">my_article</span>

|

</pre></div>
|
|||
|
|
</div>
|
|||
|
|
<p>If your Apache server has <em>mod_rewrite</em> enabled, you can easily remove this
|
|||
|
|
file by using a .htaccess file with some simple rules. Here is an example
|
|||
|
|
of such a file, using the “negative” method in which everything is redirected
|
|||
|
|
except the specified items:</p>
|
|||
|
|
<div class="highlight-apache"><div class="highlight"><pre><span></span><span class="nb">RewriteEngine</span> <span class="k">On</span>
|
|||

|
<span class="nb">RewriteCond</span> %{REQUEST_FILENAME} !-f
|
|||
|
|
<span class="nb">RewriteCond</span> %{REQUEST_FILENAME} !-d
|
|||
|
|
<span class="nb">RewriteRule</span> ^(.*)$ index.php/$1 [L]
|
|||
|
|
</pre></div>
|
|||
|
|
</div>
|
|||
|
|
<p>In the above example, any HTTP request other than those for existing
|
|||
|
|
directories and existing files is treated as a request for your index.php file.</p>

|
<div class="admonition note">

<p class="first admonition-title">Note</p>

<h2>Adding a URL Suffix<a class="headerlink" href="#adding-a-url-suffix" title="Permalink to this headline">¶</a></h2>
|
|||
|
|
<p>In your <strong>config/config.php</strong> file you can specify a suffix that will be
|
|||
|
|
added to all URLs generated by CodeIgniter. For example, if a URL is
|
|||
|
|
this:</p>
|
|||
|
|
<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nx">example</span><span class="o">.</span><span class="nx">com</span><span class="o">/</span><span class="nx">index</span><span class="o">.</span><span class="nx">php</span><span class="o">/</span><span class="nx">products</span><span class="o">/</span><span class="nx">view</span><span class="o">/</span><span class="nx">shoes</span>
|
|||
|
|
</pre></div>
|
|||
|
|
</div>
|
|||
|
|
<p>You can optionally add a suffix, like <strong>.html,</strong> making the page appear to
|
|||
|
|
be of a certain type:</p>
|
|||
|
|
<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nx">example</span><span class="o">.</span><span class="nx">com</span><span class="o">/</span><span class="nx">index</span><span class="o">.</span><span class="nx">php</span><span class="o">/</span><span class="nx">products</span><span class="o">/</span><span class="nx">view</span><span class="o">/</span><span class="nx">shoes</span><span class="o">.</span><span class="nx">html</span>

|

</div>
|

|
|
<p>CodeIgniter optionally supports this capability, which can be enabled in
|
|||
|
|
your <strong>application/config.php</strong> file. If you open your config file you’ll
|
|||
|
|
see these items:</p>
|
|||
|
|
<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$config</span><span class="p">[</span><span class="s1">'enable_query_strings'</span><span class="p">]</span> <span class="o">=</span> <span class="k">FALSE</span><span class="p">;</span>

<p>If you change “enable_query_strings” to TRUE this feature will become
|
|||
|
|
active. Your controllers and functions will then be accessible using the
|
|||
|
|
“trigger” words you’ve set to invoke your controllers and methods:</p>
|
