我正在尝试在Zend_Form
中创建自定义表单字段,以存储SWFUpload所需的HTML代码段(用于Flash文件上传程序)。
我尝试过几个不同的教程,但我感到非常困惑,到目前为止这就是我所拥有的:
/application/forms/elements/SwfUpload.php
SwfUploadHelper.php
这些文件在Bootstrap中自动加载(好吧,当然是SwfUpload.php)。
SwfUpload.php:
class Custom_Form_Element_SwfUpload extends Zend_Form_Element
{
public $helper = 'swfUpload';
}
SwfUploadHelper.php:
class Custom_Form_Helper_SwfUpload extends Zend_View_Helper_FormElement
{
public function swfUpload()
{
$html = '<div id="swfupload-control">
<p>Upload upto 5 image files(jpg, png, gif), each having maximum size of 1MB(Use Ctrl/Shift to select multiple files)</p>
<input type="button" id="button" />
<p id="queuestatus" ></p>
<ol id="log"></ol>
</div>';
return $html;
}
}
当我像这样实例化这个类时:
class Form_ApplicationForm extends Zend_Form
{
public function init()
{
$custom = new Custom_Form_Element_SwfUpload('swfupload');
// etc etc
我收到此错误:
消息:插件名称'SwfUpload' 在注册表中找不到;用过的 路径:Zend_View_Helper_: Zend公司/查看/助手/:/家庭/ mysite的/应用/视图/助理/
是不是希望我的助手在“home/mysite/application/views/helpers/
”?我尝试使用文件名“SwfUpload.php”在那里创建相同的帮助程序,但错误仍然存在。不确定我这纯粹是文件名/路径问题还是别的什么。
感谢。

这就是我最终的结果,希望它可以帮助其他人:
/application/forms/elements/SwfUpload.php
中的
class Custom_Form_Element_SwfUpload extends Zend_Form_Element
{
public $helper = 'swfUpload'; # maps to method name in SwfUpload helper
public function init()
{
$view = $this->getView();
$view->addHelperPath(APPLICATION_PATH.'/views/helpers/', 'Custom_Form_Helper');
}
}
/application/views/helpers/SwfUpload.php
中的
class Custom_Form_Helper_SwfUpload extends Zend_View_Helper_FormElement
{
public function init(){}
public function swfUpload()
{
$html = '<div id="swfupload-control">
<p>Upload upto 5 image files(jpg, png, gif), each having maximum size of 1MB(Use Ctrl/Shift to select multiple files)</p>
<input type="button" id="button" />
<p id="queuestatus" ></p>
<ol id="log"></ol>
</div>';
return $html;
}
}

API Docs for Zend_Form_Element
void __construct (string|array|Zend_Config $spec, [ $options = null])
* string|array|Zend_Config $spec
* $options
$spec may be:
* string: name of element
* array: options with which to configure element
* Zend_Config: Zend_Config with options for configuring element
* throws: Zend_Form_Exception if no element name after initialization
* access: public
看看它扔了什么?尝试
$custom = new Custom_Form_Element_SwfUpload('upload');
