Question

我正在使用扩展Zend_Form的类构建一个表单。如何在表单中添加一个img标签？我还需要为它添加一个类并对齐属性

这是我想要达到的最终结果：

<span class="myElement"><img src="myPath" align="middle" class="myClass"/>
<input type="text"></span>

我没有找到关于Zend_Form_Element_Image文档的详细信息

感谢

有库/应用程序/表单/元素/ Img.php

class Application_Form_Element_Img extends Zend_Form_Element_Xhtml
{
    public $helper = 'formImg';

    public function loadDefaultDecorators ()
    {
        parent::loadDefaultDecorators ();
        $this->removeDecorator ('Label');
        $this->removeDecorator ('HtmlTag');

        $this->addDecorator('HtmlTag', array (
        'tag'   => 'span',
        'class' => 'myElement',
        ));
    }
}

在application / view / helpers / FormImg.php

中

class Zend_View_Helper_FormImg extends Zend_View_Helper_FormElement
{
    public function formImg ($name, $value, $attribs = null)
    {
        $info = $this->_getInfo($name, $value, $attribs);

        $xHtml = '<img'
                . $this->_htmlAttribs ($attribs)
                . ' />';

        return $xHtml;
    }
}

以您的形式：

    $this->addElement ('img', 'myimage', array (
        'src'           => '/images/download.png',
        'align'         => 'right',
    ));

注意：路径可能会在您的特定应用中发生变化。

实际上，您不需要自定义元素来执行此操作。您可以使用HtmlTag装饰器并使用openOnly选项。

$form = new Zend_Form();

$form->addElement("text", "foo", array("decorators" => array(
    array(array("img" => "HtmlTag"), array(
        "tag" => "img",
        "openOnly" => true,
        "src" => "myPath",
        "align" => "middle",
        "class" => "myClass"
    )),
    array("ViewHelper"),
    array(array("span" => "HtmlTag"), array(
        "tag" => "span",
        "class" => "myElement"
    ))
)));

echo $form->foo;

您好，您可以创建一个名为“html”的自定义元素

class Zend_Form_Element_Html extends Zend_Form_Element_Xhtml
{
    public $helper = 'formHtml';
}

现在你可以打电话给它：

$yourForm->addElement(
            'html',
            'myElementId',
            array(
             'value'=>'<span class="myElement"><img src="myPath" align="middle"  class="myClass"/>
<input type="text"></span>'))
