我使用以下代码添加图像类型字段

  $fieldset->addField('filename', 'image', array(
      'label'     => Mage::helper('slider')->__('File'),
      'required'  => false,
      'name'      => 'filename',
  ));

请帮我解决这个问题

试试下面的代码。因为在编辑模式下，当用户没有选择删除或选择新图像时，您必须从数据中删除元素，因此 magento 将忽略图像字段，此问题将得到解决。我有同样的问题，所以我在尝试了几次研发后知道解决方案

if (isset($_FILES['filename']['name']) && $_FILES['filename']['name'] != '') {
    /* 
        Move uploaded file logic when user select a image
    */
} else {

    if(isset($data['filename']['delete']) && $data['filename']['delete'] == 1) {
        /*
            When user click on checkbox for deletion
        */
        $data['filename'] = '';
    } else {
        /* 
            in edit mode when user nothing did with image not 
            select for deletion nor selected new image then you must 
            be remove element from data so magento will ignore image 
            field and this issue will be resolved
        */
        unset($data['filename']);
    }
}
