<h1>Helper Functions<a class="headerlink" href="#helper-functions" title="Permalink to this headline">¶</a></h1>
|
||
<p>Helpers, as the name suggests, help you with tasks. Each helper file is
|
||
simply a collection of functions in a particular category. There are <strong>URL
|
||
Helpers</strong>, that assist in creating links, there are Form Helpers that help
|
||
you create form elements, <strong>Text Helpers</strong> perform various text formatting
|
||
routines, <strong>Cookie Helpers</strong> set and read cookies, File Helpers help you
|
||
deal with files, etc.</p>
|
||
<p>Unlike most other systems in CodeIgniter, Helpers are not written in an
|
||
Object Oriented format. They are simple, procedural functions. Each
|
||
helper function performs one specific task, with no dependence on other
|
||
functions.</p>
|
||
<p>CodeIgniter does not load Helper Files by default, so the first step in
|
||
using a Helper is to load it. Once loaded, it becomes globally available
|
||
in your <a class="reference internal" href="controllers.html"><span class="doc">controller</span></a> and
|
||
<a class="reference internal" href="views.html"><span class="doc">views</span></a>.</p>
|
||
<p>Helpers are typically stored in your <strong>system/helpers</strong>, or
|
||
<strong>application/helpers directory</strong>. CodeIgniter will look first in your
|
||
<strong>application/helpers directory</strong>. If the directory does not exist or the
|
||
specified helper is not located there CI will instead look in your
|
||
global <em>system/helpers/</em> directory.</p>
|
||
<div class="section" id="loading-a-helper">
|
||
<h2>Loading a Helper<a class="headerlink" href="#loading-a-helper" title="Permalink to this headline">¶</a></h2>
|
||
<p>Loading a helper file is quite simple using the following method:</p>
|
||
<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$this</span><span class="o">-></span><span class="na">load</span><span class="o">-></span><span class="na">helper</span><span class="p">(</span><span class="s1">'name'</span><span class="p">);</span>
|
||
</pre></div>
|
||
</div>
|
||
<p>Where <strong>name</strong> is the file name of the helper, without the .php file
|
||
extension or the “helper” part.</p>
|
||
<p>For example, to load the <strong>URL Helper</strong> file, which is named
|
||
<strong>url_helper.php</strong>, you would do this:</p>
|
||
<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$this</span><span class="o">-></span><span class="na">load</span><span class="o">-></span><span class="na">helper</span><span class="p">(</span><span class="s1">'url'</span><span class="p">);</span>
|
||
</pre></div>
|
||
</div>
|
||
<p>A helper can be loaded anywhere within your controller methods (or
|
||
even within your View files, although that’s not a good practice), as
|
||
long as you load it before you use it. You can load your helpers in your
|
||
controller constructor so that they become available automatically in
|
||
any function, or you can load a helper in a specific function that needs
|
||
it.</p>
|
||
<div class="admonition note">
|
||
<p class="first admonition-title">Note</p>
|
||
<p class="last">The Helper loading method above does not return a value, so
|
||
don’t try to assign it to a variable. Just use it as shown.</p>
|

|
||
<div class="section" id="loading-multiple-helpers">
|
||
<h2>Loading Multiple Helpers<a class="headerlink" href="#loading-multiple-helpers" title="Permalink to this headline">¶</a></h2>
|
||
<p>If you need to load more than one helper you can specify them in an
|
||
array, like this:</p>
|
||
<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$this</span><span class="o">-></span><span class="na">load</span><span class="o">-></span><span class="na">helper</span><span class="p">(</span>
|
||
<span class="k">array</span><span class="p">(</span><span class="s1">'helper1'</span><span class="p">,</span> <span class="s1">'helper2'</span><span class="p">,</span> <span class="s1">'helper3'</span><span class="p">)</span>
|
||
<span class="p">);</span>
|
||
</pre></div>

||
</div>

||
</div>
|
||
<div class="section" id="auto-loading-helpers">
|
||
<h2>Auto-loading Helpers<a class="headerlink" href="#auto-loading-helpers" title="Permalink to this headline">¶</a></h2>
|
||
<p>If you find that you need a particular helper globally throughout your
|
||
application, you can tell CodeIgniter to auto-load it during system
|
||
initialization. This is done by opening the <strong>application/config/autoload.php</strong>
|
||
file and adding the helper to the autoload array.</p>

<h2>Using a Helper<a class="headerlink" href="#using-a-helper" title="Permalink to this headline">¶</a></h2>
|
||
<p>Once you’ve loaded the Helper File containing the function you intend to
|
||
use, you’ll call it the way you would a standard PHP function.</p>
|
||
<p>For example, to create a link using the <code class="docutils literal"><span class="pre">anchor()</span></code> function in one of
|
||
your view files you would do this:</p>
|
||
<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="o"><?</span><span class="nx">php</span> <span class="k">echo</span> <span class="nx">anchor</span><span class="p">(</span><span class="s1">'blog/comments'</span><span class="p">,</span> <span class="s1">'Click Here'</span><span class="p">);</span><span class="cp">?></span>
|
||
</pre></div>
|
||
</div>
|
||
<p>Where “Click Here” is the name of the link, and “blog/comments” is the
|
||
URI to the controller/method you wish to link to.</p>
|
||
</div>
|
||
<div class="section" id="extending-helpers">
|
||
<h2>“Extending” Helpers<a class="headerlink" href="#extending-helpers" title="Permalink to this headline">¶</a></h2>
|
||
<p>To “extend” Helpers, create a file in your <strong>application/helpers/</strong> folder
|
||
with an identical name to the existing Helper, but prefixed with <strong>MY_</strong>
|
||
(this item is configurable. See below.).</p>
|
||
<p>If all you need to do is add some functionality to an existing helper -
|
||
perhaps add a function or two, or change how a particular helper
|
||
function operates - then it’s overkill to replace the entire helper with
|
||
your version. In this case it’s better to simply “extend” the Helper.</p>
|
||
<div class="admonition note">
|
||
<p class="first admonition-title">Note</p>
|
||
<p class="last">The term “extend” is used loosely since Helper functions are
|
||
procedural and discrete and cannot be extended in the traditional
|
||
programmatic sense. Under the hood, this gives you the ability to
|
||
add to or or to replace the functions a Helper provides.</p>
|
||
</div>
|
||
<p>For example, to extend the native <strong>Array Helper</strong> you’ll create a file
|
||
named <strong>application/helpers/MY_array_helper.php</strong>, and add or override
|
||

<p>The filename prefix for “extending” Helpers is the same used to extend
|
||
libraries and core classes. To set your own prefix, open your
|
||
<strong>application/config/config.php</strong> file and look for this item:</p>
|
||
<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$config</span><span class="p">[</span><span class="s1">'subclass_prefix'</span><span class="p">]</span> <span class="o">=</span> <span class="s1">'MY_'</span><span class="p">;</span>
|
||
</pre></div>
|
||
</div>
|
||
<p>Please note that all native CodeIgniter libraries are prefixed with <strong>CI_</strong>
|
||
so DO NOT use that as your prefix.</p>
