  1. POUsing HTML Entities in a Zend Form Select
    text
    copied!<p>I am populating a Select form element, and if I try to use HTML Entities in the value, it get's converted, rather than displaying the special character.</p> <p>This code:</p> <pre><code>$form-&gt;field_name-&gt;addMultiOption('value', '&amp;nbsp;&amp;bull; label'); </code></pre> <p>Renders:</p> <pre><code>&lt;option value="one"&gt;&amp;amp;nbsp;&amp;amp;bull; label&lt;/option&gt; </code></pre> <p>But I want it to be:</p> <pre><code>&lt;option value="one"&gt;&amp;nbsp;&amp;bull; label&lt;/option&gt; </code></pre> <p>How do I use HTML entities here?</p> <hr> <p><strong>Hint?</strong></p> <p>I dug in the code and found that it's using the <code>escape()</code> function from the Zend View Abstract on the label <em>AND</em> the value. Maybe someone knows how to override/overload this function for a specific form element? I don't want to override that behavior by default.</p> <p>Function from the <code>Zend_View_Helper_FormSelect</code> class</p> <pre><code>protected function _build($value, $label, $selected, $disable) { if (is_bool($disable)) { $disable = array(); } $opt = '&lt;option' . ' value="' . $this-&gt;view-&gt;escape($value) . '"' . ' label="' . $this-&gt;view-&gt;escape($label) . '"'; // selected? if (in_array((string) $value, $selected)) { $opt .= ' selected="selected"'; } // disabled? if (in_array($value, $disable)) { $opt .= ' disabled="disabled"'; } $opt .= '&gt;' . $this-&gt;view-&gt;escape($label) . "&lt;/option&gt;"; return $opt; } </code></pre> <p>This is the function from the <code>Zend_View_Abstract</code> class:</p> <pre><code>private $_escape = 'htmlspecialchars'; /* SNIP */ public function escape($var) { if (in_array($this-&gt;_escape, array('htmlspecialchars', 'htmlentities'))) { return call_user_func($this-&gt;_escape, $var, ENT_COMPAT, $this-&gt;_encoding); } return call_user_func($this-&gt;_escape, $var); } </code></pre>
