<p>The Calendar class enables you to dynamically create calendars. Your
calendars can be formatted through the use of a calendar template,
allowing 100% control over every aspect of its design. In addition, you
can pass data to your calendar cells.</p>

<div class="section" id="initializing-the-class">
<h3><a class="toc-backref" href="#id2">Initializing the Class</a><a class="headerlink" href="#initializing-the-class" title="Permalink to this headline"></a></h3>
<p>Like most other classes in CodeIgniter, the Calendar class is
initialized in your controller using the $this-&gt;load-&gt;library function:</p>
<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$this</span><span class="o">-&gt;</span><span class="na">load</span><span class="o">-&gt;</span><span class="na">library</span><span class="p">(</span><span class="s1">&#39;calendar&#39;</span><span class="p">);</span>
</pre></div>
</div>
<p>Once loaded, the Calendar object will be available using:</p>
<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$this</span><span class="o">-&gt;</span><span class="na">calendar</span>
</pre></div>
</div>

<div class="section" id="displaying-a-calendar">
<h3><a class="toc-backref" href="#id3">Displaying a Calendar</a><a class="headerlink" href="#displaying-a-calendar" title="Permalink to this headline"></a></h3>
<p>Here is a very simple example showing how you can display a calendar:</p>
<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$this</span><span class="o">-&gt;</span><span class="na">load</span><span class="o">-&gt;</span><span class="na">library</span><span class="p">(</span><span class="s1">&#39;calendar&#39;</span><span class="p">);</span>
<span class="k">echo</span> <span class="nv">$this</span><span class="o">-&gt;</span><span class="na">calendar</span><span class="o">-&gt;</span><span class="na">generate</span><span class="p">();</span>
</pre></div>
</div>
<p>The above code will generate a calendar for the current month/year based
on your server time. To show a calendar for a specific month and year
you will pass this information to the calendar generating function:</p>
<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$this</span><span class="o">-&gt;</span><span class="na">load</span><span class="o">-&gt;</span><span class="na">library</span><span class="p">(</span><span class="s1">&#39;calendar&#39;</span><span class="p">);</span>
<span class="k">echo</span> <span class="nv">$this</span><span class="o">-&gt;</span><span class="na">calendar</span><span class="o">-&gt;</span><span class="na">generate</span><span class="p">(</span><span class="mi">2006</span><span class="p">,</span> <span class="mi">6</span><span class="p">);</span>
</pre></div>
</div>
<p>The above code will generate a calendar showing the month of June in
2006. The first parameter specifies the year, the second parameter
specifies the month.</p>
</div>
<div class="section" id="passing-data-to-your-calendar-cells">
<h3><a class="toc-backref" href="#id4">Passing Data to your Calendar Cells</a><a class="headerlink" href="#passing-data-to-your-calendar-cells" title="Permalink to this headline"></a></h3>
<p>To add data to your calendar cells involves creating an associative
array in which the keys correspond to the days you wish to populate and
the array value contains the data. The array is passed to the third
parameter of the calendar generating function. Consider this example:</p>
<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$this</span><span class="o">-&gt;</span><span class="na">load</span><span class="o">-&gt;</span><span class="na">library</span><span class="p">(</span><span class="s1">&#39;calendar&#39;</span><span class="p">);</span>
<span class="nv">$data</span> <span class="o">=</span> <span class="k">array</span><span class="p">(</span>
<span class="mi">3</span> <span class="o">=&gt;</span> <span class="s1">&#39;http://example.com/news/article/2006/06/03/&#39;</span><span class="p">,</span>
<span class="mi">7</span> <span class="o">=&gt;</span> <span class="s1">&#39;http://example.com/news/article/2006/06/07/&#39;</span><span class="p">,</span>

<span class="mi">26</span> <span class="o">=&gt;</span> <span class="s1">&#39;http://example.com/news/article/2006/06/26/&#39;</span>
<span class="p">);</span>
<span class="k">echo</span> <span class="nv">$this</span><span class="o">-&gt;</span><span class="na">calendar</span><span class="o">-&gt;</span><span class="na">generate</span><span class="p">(</span><span class="mi">2006</span><span class="p">,</span> <span class="mi">6</span><span class="p">,</span> <span class="nv">$data</span><span class="p">);</span>
</pre></div>
</div>
<p>Using the above example, day numbers 3, 7, 13, and 26 will become links
pointing to the URLs you’ve provided.</p>
<div class="admonition note">
<p class="first admonition-title">Note</p>
<p class="last">By default it is assumed that your array will contain links.
In the section that explains the calendar template below you’ll see how
you can customize how data passed to your cells is handled so you can
pass different types of information.</p>

</div>
<div class="section" id="setting-display-preferences">
<h3><a class="toc-backref" href="#id5">Setting Display Preferences</a><a class="headerlink" href="#setting-display-preferences" title="Permalink to this headline"></a></h3>
<p>There are seven preferences you can set to control various aspects of
the calendar. Preferences are set by passing an array of preferences in
the second parameter of the loading function. Here is an example:</p>
<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$prefs</span> <span class="o">=</span> <span class="k">array</span><span class="p">(</span>
<span class="s1">&#39;start_day&#39;</span> <span class="o">=&gt;</span> <span class="s1">&#39;saturday&#39;</span><span class="p">,</span>
<span class="s1">&#39;month_type&#39;</span> <span class="o">=&gt;</span> <span class="s1">&#39;long&#39;</span><span class="p">,</span>
<span class="s1">&#39;day_type&#39;</span> <span class="o">=&gt;</span> <span class="s1">&#39;short&#39;</span>
<span class="p">);</span>
<span class="nv">$this</span><span class="o">-&gt;</span><span class="na">load</span><span class="o">-&gt;</span><span class="na">library</span><span class="p">(</span><span class="s1">&#39;calendar&#39;</span><span class="p">,</span> <span class="nv">$prefs</span><span class="p">);</span>

</pre></div>
</div>
<p>The above code would start the calendar on saturday, use the “long”
month heading, and the “short” day names. More information regarding
preferences below.</p>

<h3><a class="toc-backref" href="#id6">Showing Next/Previous Month Links</a><a class="headerlink" href="#showing-next-previous-month-links" title="Permalink to this headline"></a></h3>
<p>To allow your calendar to dynamically increment/decrement via the
next/previous links requires that you set up your calendar code similar
to this example:</p>
<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$prefs</span> <span class="o">=</span> <span class="k">array</span><span class="p">(</span>
<span class="s1">&#39;show_next_prev&#39;</span> <span class="o">=&gt;</span> <span class="k">TRUE</span><span class="p">,</span>

<span class="p">);</span>
<span class="nv">$this</span><span class="o">-&gt;</span><span class="na">load</span><span class="o">-&gt;</span><span class="na">library</span><span class="p">(</span><span class="s1">&#39;calendar&#39;</span><span class="p">,</span> <span class="nv">$prefs</span><span class="p">);</span>

</pre></div>
</div>
<p>You’ll notice a few things about the above example:</p>
<ul class="simple">
<li>You must set the “show_next_prev” to TRUE.</li>
<li>You must supply the URL to the controller containing your calendar in
the “next_prev_url” preference. If you don’t, it will be set to the current
<em>controller/method</em>.</li>
<li>You must supply the “year” and “month” to the calendar generating
function via the URI segments where they appear (Note: The calendar
class automatically adds the year/month to the base URL you
provide.).</li>
</ul>
