Question

你好我正在使用 Zend Framework Form ，并试图让这个例子工作http://framework.zend.com/issues/browse/ZF-8252，但它失败了xD

这是我的代码

$options = Array
(
    [] => Qualsiasi Agente
    [agenti_attivi] => Array
        (
            [4] => Giovanni Abc
            [10] => Luigi Abc
            [13] => Michela Abc
        )

);

$agenti->addMultiOptions($options);

，生成的代码为：

<select name="agente_id" id="agente_id" tabindex="6">
    <option value="" label="Qualsiasi Agente" selected="selected">Qualsiasi Agente</option>
    <optgroup id="agente_id-optgroup-Agenti attivi: " label="Agenti attivi: ">
    <option value="4" label="Giovanni Abc">Giovanni Abc</option>
    <option value="10" label="Luigi Capoarea">Luigi Abc</option>
    <option value="13" label="Michela Abc">Michela Abc</option>
    </optgroup>

</select>

其中 id =“agente_id-optgroup-Agenti attivi：”不是xhtml有效第724行，第44列：属性“id”的值必须是单个令牌

我正在使用zend 1.11.10

感谢

创建一个自定义视图助手FormSelect，扩展核心FormSelect，然后修改代码。

在引导程序文件中包含视图助手的路径

protected function _initHelpers()
{
    $this->bootstrap('view');
    $view = $this->getResource('view');
    $view->addHelperPath('My/View/Helper', 'My_View_Helper');
}

自定义视图助手。它是Zend_View_Helper_FormSelect的副本，但修改很少。

类My_View_Helper_FormSelect扩展Zend_View_Helper_FormSelect {

public function formSelect($name, $value = null, $attribs = null,
    $options = null, $listsep = "<br />\n")
{
    $info = $this->_getInfo($name, $value, $attribs, $options, $listsep);
    extract($info); // name, id, value, attribs, options, listsep, disable

    // force $value to array so we can compare multiple values to multiple
    // options; also ensure it's a string for comparison purposes.
    $value = array_map('strval', (array) $value);

    // check if element may have multiple values
    $multiple = '';

    if (substr($name, -2) == '[]') {
        // multiple implied by the name
        $multiple = ' multiple="multiple"';
    }

    if (isset($attribs['multiple'])) {
        // Attribute set
        if ($attribs['multiple']) {
            // True attribute; set multiple attribute
            $multiple = ' multiple="multiple"';

            // Make sure name indicates multiple values are allowed
            if (!empty($multiple) && (substr($name, -2) != '[]')) {
                $name .= '[]';
            }
        } else {
            // False attribute; ensure attribute not set
            $multiple = '';
        }
        unset($attribs['multiple']);
    }

    // now start building the XHTML.
    $disabled = '';
    if (true === $disable) {
        $disabled = ' disabled="disabled"';
    }

    // Build the surrounding select element first.
    $xhtml = '<select'
            . ' name="' . $this->view->escape($name) . '"'
            . ' id="' . $this->view->escape($id) . '"'
            . $multiple
            . $disabled
            . $this->_htmlAttribs($attribs)
            . ">\n    ";

    // build the list of options
    $list       = array();
    $translator = $this->getTranslator();
    foreach ((array) $options as $opt_value => $opt_label) {
        if (is_array($opt_label)) {
            $opt_disable = '';
            if (is_array($disable) && in_array($opt_value, $disable)) {
                $opt_disable = ' disabled="disabled"';
            }
            if (null !== $translator) {
                $opt_value = $translator->translate($opt_value);
            }
            $opt_id = ' id="' . $this->formatElementId($id . '-optgroup-' . $opt_value) . '"';
            $list[] = '<optgroup'
                    . $opt_disable
                    . $opt_id
                    . ' label="' . $this->view->escape($opt_value) .'">';
            foreach ($opt_label as $val => $lab) {
                $list[] = $this->_build($val, $lab, $value, $disable);
            }
            $list[] = '</optgroup>';
        } else {
            $list[] = $this->_build($opt_value, $opt_label, $value, $disable);
        }
    }

    // add the options to the xhtml and close the select
    $xhtml .= implode("\n    ", $list) . "\n</select>";

    return $xhtml;
}

private function formatElementId($id)
{
    // in here put whatever filter you want for the id value
    $id = trim(strtr($id, array('[' => '-', ']' => '', ' ' => '', ':' => '')), '-');
    $id = strtolower($id);
    return $id;
}

}

完成。创建具有有效ID的多选元素。

<?php
$this->addElement('multiSelect', 'agente_id', array(
    'label' => 'Label Name:',
    'multiOptions' => array(
        '' => 'Qualsiasi Agente',
        'Agenti attivi: ' => array(
            4 => 'Giovanni Verdi',
            10 => 'Luigi Capoarea',
            13 => 'Michela Passarin',
        )
    )
));

Answer 2

试试这个，它对我有用：

$select = new Zend_Form_Element_Select('select');
$options = Array(
    '' => 'Qualsiasi Agente',
    'agenti_attivi' => Array(
            4 => 'Giovanni Verdi',
            10 => 'Luigi Capoarea',
            13 => 'Michela Passarin'
        )
);
$this->addElements(array($xxxx,$select,$yyyy)); // $this : the form instance

结果是：

<select id="select" name="select">
  <option label="Qualsiasi Agente" value="">Qualsiasi Agente</option>
  <optgroup label="agenti_attivi">
    <option label="Giovanni Verdi" value="4">Giovanni Verdi</option>
    <option label="Luigi Capoarea" value="10">Luigi Capoarea</option>
    <option label="Michela Passarin" value="13">Michela Passarin</option>
  </optgroup>
</select>

问题是id属性不接受空格和特殊字符：

id="agente_id-optgroup-Agenti attivi: "

在给定doctype的情况下，Zend通常非常适合渲染正确的html。

如果您还没有，请尝试设置您的doctype。



<?php
$viewRenderer = Zend_Controller_Action_HelperBroker::getStaticHelper('viewRenderer');
$viewRenderer->initView();
$viewRenderer->view->doctype('XHTML1_STRICT');

<?php $viewRenderer = Zend_Controller_Action_HelperBroker::getStaticHelper('viewRenderer'); $viewRenderer->initView(); $viewRenderer->view->doctype('XHTML1_STRICT');

和

<?php echo $this->doctype(); ?>

位于布局顶部

我没有安装ZF我可以轻松搞定，如果这不能正常设置测试环境。
