<h1>Template Parser Class<a class="headerlink" href="#template-parser-class" title="Permalink to this headline">¶</a></h1>
<p>The Template Parser Class can perform simple text substitution for
pseudo-variables contained within your view files.
It can parse simple variables or variable tag pairs.</p>
<p>If you’ve never used a template engine,
pseudo-variable names are enclosed in braces, like this:</p>
<div class="highlight-ci"><div class="highlight"><pre><span class="o"><</span><span class="nx">html</span><span class="o">></span>
<span class="o"><</span><span class="nx">head</span><span class="o">></span>

<span class="o"></</span><span class="nx">html</span><span class="o">></span>
</pre></div>
</div>
<p>These variables are not actual PHP variables, but rather plain text
representations that allow you to eliminate PHP from your templates
(view files).</p>
<div class="admonition note">
<p class="first admonition-title">Note</p>
<p class="last">CodeIgniter does <strong>not</strong> require you to use this class since
using pure PHP in your view pages lets them run a little faster.
However, some developers prefer to use a template engine if
they work with designers who they feel would find some
confusion working with PHP.</p>

<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 Parser class is initialized
in your controller using the <tt class="docutils literal"><span class="pre">$this->load->library()</span></tt> method:</p>
<div class="highlight-ci"><div class="highlight"><pre><span class="nv">$this</span><span class="o">-></span><span class="na">load</span><span class="o">-></span><span class="na">library</span><span class="p">(</span><span class="s1">'parser'</span><span class="p">);</span>
</pre></div>
</div>
<p>Once loaded, the Parser library object will be available using:
$this->parser</p>
</div>
<div class="section" id="parsing-templates">
<h3><a class="toc-backref" href="#id3">Parsing templates</a><a class="headerlink" href="#parsing-templates" title="Permalink to this headline">¶</a></h3>
<p>You can use the <tt class="docutils literal"><span class="pre">parse()</span></tt> method to parse (or render) simple templates,
like this:</p>
<div class="highlight-ci"><div class="highlight"><pre><span class="nv">$data</span> <span class="o">=</span> <span class="k">array</span><span class="p">(</span>
<span class="s1">'blog_title'</span> <span class="o">=></span> <span class="s1">'My Blog Title'</span><span class="p">,</span>
<span class="s1">'blog_heading'</span> <span class="o">=></span> <span class="s1">'My Blog Heading'</span>
<span class="p">);</span>
<span class="nv">$this</span><span class="o">-></span><span class="na">parser</span><span class="o">-></span><span class="na">parse</span><span class="p">(</span><span class="s1">'blog_template'</span><span class="p">,</span> <span class="nv">$data</span><span class="p">);</span>
</pre></div>
</div>
<p>The first parameter contains the name of the <a class="reference internal" href="../general/views.html"><em>view
file</em></a> (in this example the file would be called
blog_template.php), and the second parameter contains an associative
array of data to be replaced in the template. In the above example, the
template would contain two variables: {blog_title} and {blog_heading}</p>
<p>There is no need to “echo” or do something with the data returned by
$this->parser->parse(). It is automatically passed to the output class
to be sent to the browser. However, if you do want the data returned
instead of sent to the output class you can pass TRUE (boolean) as the
third parameter:</p>
<div class="highlight-ci"><div class="highlight"><pre><span class="nv">$string</span> <span class="o">=</span> <span class="nv">$this</span><span class="o">-></span><span class="na">parser</span><span class="o">-></span><span class="na">parse</span><span class="p">(</span><span class="s1">'blog_template'</span><span class="p">,</span> <span class="nv">$data</span><span class="p">,</span> <span class="k">TRUE</span><span class="p">);</span>
</pre></div>
</div>
</div>
<div class="section" id="variable-pairs">
<h3><a class="toc-backref" href="#id4">Variable Pairs</a><a class="headerlink" href="#variable-pairs" title="Permalink to this headline">¶</a></h3>
<p>The above example code allows simple variables to be replaced. What if
you would like an entire block of variables to be repeated, with each
iteration containing new values? Consider the template example we showed
at the top of the page:</p>
<div class="highlight-ci"><div class="highlight"><pre><span class="o"><</span><span class="nx">html</span><span class="o">></span>
<span class="o"><</span><span class="nx">head</span><span class="o">></span>
<span class="o"><</span><span class="nx">title</span><span class="o">></span><span class="p">{</span><span class="nx">blog_title</span><span class="p">}</span><span class="o"></</span><span class="nx">title</span><span class="o">></span>
<span class="o"></</span><span class="nx">head</span><span class="o">></span>
<span class="o"><</span><span class="nx">body</span><span class="o">></span>
<span class="o"><</span><span class="nx">h3</span><span class="o">></span><span class="p">{</span><span class="nx">blog_heading</span><span class="p">}</span><span class="o"></</span><span class="nx">h3</span><span class="o">></span>
<span class="p">{</span><span class="nx">blog_entries</span><span class="p">}</span>
<span class="o"><</span><span class="nx">h5</span><span class="o">></span><span class="p">{</span><span class="nx">title</span><span class="p">}</span><span class="o"></</span><span class="nx">h5</span><span class="o">></span>
<span class="o"><</span><span class="nx">p</span><span class="o">></span><span class="p">{</span><span class="nx">body</span><span class="p">}</span><span class="o"></</span><span class="nx">p</span><span class="o">></span>
<span class="p">{</span><span class="o">/</span><span class="nx">blog_entries</span><span class="p">}</span>
<span class="o"></</span><span class="nx">body</span><span class="o">></span>
<span class="o"></</span><span class="nx">html</span><span class="o">></span>
</pre></div>
</div>
<p>In the above code you’ll notice a pair of variables: {blog_entries}
data... {/blog_entries}. In a case like this, the entire chunk of data
between these pairs would be repeated multiple times, corresponding to
the number of rows in the “blog_entries” element of the parameters array.</p>
<p>Parsing variable pairs is done using the identical code shown above to
parse single variables, except, you will add a multi-dimensional array
corresponding to your variable pair data. Consider this example:</p>
<div class="highlight-ci"><div class="highlight"><pre><span class="nv">$this</span><span class="o">-></span><span class="na">load</span><span class="o">-></span><span class="na">library</span><span class="p">(</span><span class="s1">'parser'</span><span class="p">);</span>
<span class="nv">$data</span> <span class="o">=</span> <span class="k">array</span><span class="p">(</span>
<span class="s1">'blog_title'</span> <span class="o">=></span> <span class="s1">'My Blog Title'</span><span class="p">,</span>
<span class="s1">'blog_heading'</span> <span class="o">=></span> <span class="s1">'My Blog Heading'</span><span class="p">,</span>
<span class="s1">'blog_entries'</span> <span class="o">=></span> <span class="k">array</span><span class="p">(</span>
<span class="k">array</span><span class="p">(</span><span class="s1">'title'</span> <span class="o">=></span> <span class="s1">'Title 1'</span><span class="p">,</span> <span class="s1">'body'</span> <span class="o">=></span> <span class="s1">'Body 1'</span><span class="p">),</span>

</pre></div>
</div>
<p>If your “pair” data is coming from a database result, which is already a
multi-dimensional array, you can simply use the database <tt class="docutils literal"><span class="pre">result_array()</span></tt>
method:</p>
<div class="highlight-ci"><div class="highlight"><pre><span class="nv">$query</span> <span class="o">=</span> <span class="nv">$this</span><span class="o">-></span><span class="na">db</span><span class="o">-></span><span class="na">query</span><span class="p">(</span><span class="s2">"SELECT * FROM blog"</span><span class="p">);</span>

template, the original pseudo-variable is shown in the result:</p>
<div class="highlight-ci"><div class="highlight"><pre><span class="nv">$template</span> <span class="o">=</span> <span class="s1">'Hello, {firstname} {initials} {lastname}'</span><span class="p">;</span>
<span class="nv">$data</span> <span class="o">=</span> <span class="k">array</span><span class="p">(</span>
<span class="s1">'title'</span> <span class="o">=></span> <span class="s1">'Mr'</span><span class="p">,</span>

<span class="s1">'lastname'</span> <span class="o">=></span> <span class="s1">'Doe'</span>
<span class="p">);</span>
<span class="nv">$this</span><span class="o">-></span><span class="na">parser</span><span class="o">-></span><span class="na">parse_string</span><span class="p">(</span><span class="nv">$template</span><span class="p">,</span> <span class="nv">$data</span><span class="p">);</span>
<span class="c1">// Result: Hello, John {initials} Doe</span>
</pre></div>
</div>
<p>If you provide a string substitution parameter when an array is expected,
i.e. for a variable pair, the substitution is done for the opening variable
pair tag, but the closing variable pair tag is not rendered properly:</p>
<div class="highlight-ci"><div class="highlight"><pre><span class="nv">$template</span> <span class="o">=</span> <span class="s1">'Hello, {firstname} {lastname} ({degrees}{degree} {/degrees})'</span><span class="p">;</span>

<span class="c1">// Result: Hello, John Doe (Mr{degree} {/degrees})</span>

</div>
<p>If you name one of your individual substitution parameters the same as one
used inside a variable pair, the results may not be as expected:</p>
<div class="highlight-ci"><div class="highlight"><pre><span class="nv">$template</span> <span class="o">=</span> <span class="s1">'Hello, {firstname} {lastname} ({degrees}{degree} {/degrees})'</span><span class="p">;</span>

<p>You do not have to use variable pairs to get the effect of iteration in
your views. It is possible to use a view fragment for what would be inside
a variable pair, and to control the iteration in your controller instead
of in the view.</p>
<p>An example with the iteration controlled in the view:</p>
<div class="highlight-ci"><div class="highlight"><pre><span class="nv">$template</span> <span class="o">=</span> <span class="s1">'<ul>{menuitems}</span>
