问题描述

如何创建Magento管理员自定义模块，请点击添加字段按钮以为实体选择新属性的类型文件"

How to create Magento admin custom module click add field button for entity select type 'file' for the new attribute

这是表单代码:

$fieldset->addField('uploadpdf', 'file', array(
        'label' => Mage::helper('promotionsoffers')->__('Upload PDF'),
        'name'  => 'uploadpdf',

    ));`

推荐答案

这是要通过Magento的表单库实现类似功能，我们将以这种方式对其代码进行一些修改

To achieve similar through Magento's Form Library, we will modify its code a bit in this way

修改lib/Varien/Data/Form/Element/Abstract.php的getElementHtml方法

Modify getElementHtml method of lib/Varien/Data/Form/Element/Abstract.php

public function getElementHtml()
{
    if($this->getType()=='file' && $this->getMultiple())
        $_multiple = ' multiple';
    $html = '<input id="'.$this->getHtmlId().'" name="'.$this->getName()
         .'" value="'.$this->getEscapedValue().'" '.$this->serialize($this->getHtmlAttributes()).$_multiple.'/>'."\n";
    $html.= $this->getAfterElementHtml();
    return $html;
}

，然后像这样在字段声明中传递新属性multiple=>true

and then just pass new attribute multiple=>true in you field declaration like this

$fieldset->addField('uploadpdf', 'file', array(
    'label' => Mage::helper('promotionsoffers')->__('Upload PDF'),
    'name'  => 'uploadpdf[]',
    'multiple'=>true
));
