限时删除!!

我遵循,在我的Magento中进行图片上传模块,但所有代码所做的最大的事情是通过POST传递选定的文件名: $ _ FILES 数组是空的,只要我添加 image











 <?php 
class Moo_News_Block_Adminhtml_News_Edit_Tab_Form extends Mage_Adminhtml_Block_Widget_Form
{
protected function _prepareForm()
{
$ form = new Varien_Data_Form();
$ this-> setForm($ form);
$ fieldset = $ form-> addFieldset('news_form',array('legend'=> Mage :: helper('news') - > __('Item information')));

$ fieldset-> addField('title','text',array(
'label'=> Mage :: helper('news') - > __(' Title'),
'class'=>'required-entry',
'required'=> true,
'name'=>'title',
));

$ fieldset-> addField('published','select',array(
'label'=> Mage :: helper('news') - > __('
'name'=>'published',
'required'=> true,
'values'=> array(
array(
'value'=> 1,
'label'=> Mage :: helper('news') - &__('Yes'),
),

array(
'value'=> 0,
'label'=> Mage :: helper('news') - > __('No'),
),
),
));

$ fieldset-> addField('short_description','editor',array(
'name'=>'short_description',
'label'=>法师:: helper('news') - > __('Short Description'),
'title'=> Mage :: helper('news') - & b $ b'style'=>'width:98%; height:200px;',
'wysiwyg'=> false,
'required'=> true,
) );

$ fieldset-> addField('body','editor',array(
'name'=>'body',
'label'=>法师:: helper('news') - > __('Body'),
'title'=> Mage :: helper('news') - &__('Body'),
'style'=>'width:98%; height:400px;',
'wysiwyg'=> false,
'required'=> true,
));

$ b $ fieldset-> addField('image','file',array(
'label'=> Mage :: helper('news') - > ; __('Image'),
'required'=> false,
'name'=>'image',
)); (Mage :: getSingleton('adminhtml / session') - > getNewsData())
{
$ form-> setValues(Mage :: getSingleton(' adminhtml /会话') - > getNewsData());
Mage :: getSingleton('adminhtml / session') - > setNewsData(null);
} elseif(Mage :: registry('news_data')){
$ form-> setValues(Mage :: registry('news_data') - > getData());
}

返回parent :: _ prepareForm();

$ b所以,问题是:我应该怎么做在一个正确的方式吗?

解决方案
诀窍是改变默认的表单创建代码

  $ form = new Varien_Data_Form(array(
'id'=>'edit_form',
'action'=> $ this-> ; getUrl('* / * / save',array('id'=> $ this-> getRequest() - > getParam('id'))),
'method'=>'后',
));

  $ form = new Varien_Data_Form(array(
'id'=>'edit_form',
'action'=> $ this-> getUrl('* / * / save' ('id'=> $ this-> getRequest() - > getParam('id'))),
'method'=>'post',
'enctype' =>'multipart / form-data'
));

不在我提供的代码中,但是在调用者内部( ..._ Adminhtml_News_Edit_Form 而不是 ..._ Adminhtml_News_Edit_Tab_Form )。


I followed this link to make image upload work within my Magento module, but the greatest thing all that code does is passing selected file name via POST: $_FILES array is empty whenever i add image or file fields.

Here's my code:

<?php
class Moo_News_Block_Adminhtml_News_Edit_Tab_Form extends Mage_Adminhtml_Block_Widget_Form
{
    protected function _prepareForm()
    {
        $form = new Varien_Data_Form();
        $this->setForm($form);
        $fieldset = $form->addFieldset('news_form', array('legend' => Mage::helper('news')->__('Item information')));

        $fieldset->addField('title', 'text', array(
            'label'     => Mage::helper('news')->__('Title'),
            'class'     => 'required-entry',
            'required'  => true,
            'name'      => 'title',
        ));

        $fieldset->addField('published', 'select', array(
            'label'     => Mage::helper('news')->__('Published'),
            'name'      => 'published',
            'required'  => true,
            'values'    => array(
                array(
                    'value'     => 1,
                    'label'     => Mage::helper('news')->__('Yes'),
                ),

                array(
                    'value'     => 0,
                    'label'     => Mage::helper('news')->__('No'),
                ),
            ),
        ));

        $fieldset->addField('short_description', 'editor', array(
            'name'      => 'short_description',
            'label'     => Mage::helper('news')->__('Short Description'),
            'title'     => Mage::helper('news')->__('Short Description'),
            'style'     => 'width:98%; height:200px;',
            'wysiwyg'   => false,
            'required'  => true,
        ));

        $fieldset->addField('body', 'editor', array(
            'name'      => 'body',
            'label'     => Mage::helper('news')->__('Body'),
            'title'     => Mage::helper('news')->__('Body'),
            'style'     => 'width:98%; height:400px;',
            'wysiwyg'   => false,
            'required'  => true,
        ));


        $fieldset->addField('image', 'file', array(
            'label'     => Mage::helper('news')->__('Image'),
            'required'  => false,
            'name'      => 'image',
        ));

        if ( Mage::getSingleton('adminhtml/session')->getNewsData() )
        {
            $form->setValues(Mage::getSingleton('adminhtml/session')->getNewsData());
            Mage::getSingleton('adminhtml/session')->setNewsData(null);
        } elseif ( Mage::registry('news_data') ) {
            $form->setValues(Mage::registry('news_data')->getData());
        }

        return parent::_prepareForm();
    }
}

and the controller code:

            }
        }
        $this->_redirect('*/*/');
    }
    /**
     * Product grid for AJAX request.
     * Sort and filter result for example.
     */
    public function gridAction()
    {
        $this->loadLayout();
        $this->getResponse()->setBody(
               $this->getLayout()->createBlock('importedit/adminhtml_news_grid')->toHtml()
        );
    }
}

So, the question is: how should i do this in a right way?

解决方案

The trick was to change the default form creation code

$form = new Varien_Data_Form(array(
    'id' => 'edit_form',
    'action' => $this->getUrl('*/*/save', array('id' => $this->getRequest()->getParam('id'))),
    'method' => 'post',
));

to

$form = new Varien_Data_Form(array(
    'id' => 'edit_form',
    'action' => $this->getUrl('*/*/save', array('id' => $this->getRequest()->getParam('id'))),
    'method' => 'post',
    'enctype' => 'multipart/form-data'
));

Not within the code i've provided, but within the caller for that partial (..._Adminhtml_News_Edit_Form instead of ..._Adminhtml_News_Edit_Tab_Form).
