| <p>If you’ve never used a template engine, |

| <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 <code class="docutils literal"><span class="pre">$this->load->library()</span></code> method:</p> |
| <div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$this</span><span class="o">-></span><span class="na">load</span><span class="o">-></span><span class="na">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: |
| $this->parser</p> |
| </div> |
| <div class="section" id="parsing-templates"> |
| <h3><a class="toc-backref" href="#id3">Parsing templates</a><a class="headerlink" href="#parsing-templates" title="Permalink to this headline">¶</a></h3> |
| <p>You can use the <code class="docutils literal"><span class="pre">parse()</span></code> method to parse (or render) simple templates, |
| like this:</p> |
| <div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$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="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"><span class="doc">view |
| file</span></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 |
| $this->parser->parse(). It is automatically passed to the output class |
| to be sent to the browser. However, if you do want the data returned |
| instead of sent to the output class you can pass TRUE (boolean) as the |
| third parameter:</p> |
| <div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$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> |

| <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></span><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">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></span><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="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> |
