+<p>Creates an opening form tag with a base URL <strong>built from your config preferences</strong>.
+It will optionally let you add form attributes and hidden input fields, and
+will always add the <cite>accept-charset</cite> attribute based on the charset value in your
+config file.</p>
+<p>The main benefit of using this tag rather than hard coding your own HTML is that
+it permits your site to be more portable in the event your URLs ever change.</p>
+<p>Here’s a simple example:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="k">echo</span> <span class="nx">form_open</span><span class="p">(</span><span class="s1">&#39;email/send&#39;</span><span class="p">);</span>
+</pre></div>
+</div>
+<p>The above example would create a form that points to your base URL plus the
+“email/send” URI segments, like this:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="o">&lt;</span><span class="nx">form</span> <span class="nx">method</span><span class="o">=</span><span class="s2">&quot;post&quot;</span> <span class="nx">accept</span><span class="o">-</span><span class="nx">charset</span><span class="o">=</span><span class="s2">&quot;utf-8&quot;</span> <span class="nx">action</span><span class="o">=</span><span class="s2">&quot;http://example.com/index.php/email/send&quot;</span><span class="o">&gt;</span>
+</pre></div>
+</div>
+<p><strong>Adding Attributes</strong></p>
+<blockquote>
+<div><p>Attributes can be added by passing an associative array to the second
+parameter, like this:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$attributes</span> <span class="o">=</span> <span class="k">array</span><span class="p">(</span><span class="s1">&#39;class&#39;</span> <span class="o">=&gt;</span> <span class="s1">&#39;email&#39;</span><span class="p">,</span> <span class="s1">&#39;id&#39;</span> <span class="o">=&gt;</span> <span class="s1">&#39;myform&#39;</span><span class="p">);</span>
+<span class="k">echo</span> <span class="nx">form_open</span><span class="p">(</span><span class="s1">&#39;email/send&#39;</span><span class="p">,</span> <span class="nv">$attributes</span><span class="p">);</span>
+</pre></div>
+</div>
+<p>Alternatively, you can specify the second parameter as a string:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="k">echo</span> <span class="nx">form_open</span><span class="p">(</span><span class="s1">&#39;email/send&#39;</span><span class="p">,</span> <span class="s1">&#39;class=&quot;email&quot; id=&quot;myform&quot;&#39;</span><span class="p">);</span>
+</pre></div>
+</div>
+<p>The above examples would create a form similar to this:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="o">&lt;</span><span class="nx">form</span> <span class="nx">method</span><span class="o">=</span><span class="s2">&quot;post&quot;</span> <span class="nx">accept</span><span class="o">-</span><span class="nx">charset</span><span class="o">=</span><span class="s2">&quot;utf-8&quot;</span> <span class="nx">action</span><span class="o">=</span><span class="s2">&quot;http://example.com/index.php/email/send&quot;</span> <span class="nx">class</span><span class="o">=</span><span class="s2">&quot;email&quot;</span> <span class="nx">id</span><span class="o">=</span><span class="s2">&quot;myform&quot;</span><span class="o">&gt;</span>
+</pre></div>
+</div>
+</div></blockquote>
+<p><strong>Adding Hidden Input Fields</strong></p>
+<blockquote>
+<div><p>Hidden fields can be added by passing an associative array to the
+third parameter, like this:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="nv">$hidden</span> <span class="o">=</span> <span class="k">array</span><span class="p">(</span><span class="s1">&#39;username&#39;</span> <span class="o">=&gt;</span> <span class="s1">&#39;Joe&#39;</span><span class="p">,</span> <span class="s1">&#39;member_id&#39;</span> <span class="o">=&gt;</span> <span class="s1">&#39;234&#39;</span><span class="p">);</span>
+<span class="k">echo</span> <span class="nx">form_open</span><span class="p">(</span><span class="s1">&#39;email/send&#39;</span><span class="p">,</span> <span class="s1">&#39;&#39;</span><span class="p">,</span> <span class="nv">$hidden</span><span class="p">);</span>
+</pre></div>
+</div>
+<p>You can skip the second parameter by passing any falsy value to it.</p>
+<p>The above example would create a form similar to this:</p>
+<div class="highlight-ci"><div class="highlight"><pre><span></span><span class="o">&lt;</span><span class="nx">form</span> <span class="nx">method</span><span class="o">=</span><span class="s2">&quot;post&quot;</span> <span class="nx">accept</span><span class="o">-</span><span class="nx">charset</span><span class="o">=</span><span class="s2">&quot;utf-8&quot;</span> <span class="nx">action</span><span class="o">=</span><span class="s2">&quot;http://example.com/index.php/email/send&quot;</span><span class="o">&gt;</span>
