I have tried above mentiion to allow multple images , but failed.

• Fabian Blechschmidt: If it is enough, you can just add multiple file input fields. Is multiple limited? Or is multiple 0+?

Answer 1

The only "multiple image" widget available in a default Magento install is the EAV Attribute type gallery.

I'm pretty sure however that you'll need to implement the same Adminhtml_Widgets in order to use it on something other than a product (like a custom EAV Entity with a custom form).

If you just need a custom form (without a custom entity or for a custom Flat entity) you may be better off creating your own Controllers and implementing SWF Upload yourself using your own logic/structures.

Answer 2

You should change this function getElementHtml in this file lib\Varien\Data\Form\Element\Abstract.php like this:

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;
 }

after that you able to upload multiple file with your file field

Example: In form file

 $fieldset->addField('optionimage', 'file', array(
 'label' => Mage::helper('option_module')->__('Option Image'),
 'required' => false,
 'name' => 'optionimage[]',
 'multiple'=>true,
 'multiple'=>'multiple'
 ));

and in your controller

You should change your 'name' value and add '[]', finally it should looks like this:

$fieldset->addField('image', 'image', array(
 'label' => Mage::helper('featuredsalons')->__('Image'),
 'required' => true,
 'multiple' => 'multiple', 
 'name' => 'image[]',
 'after_element_html' => '<p class="note"><span>Image Dimension: </span></p>'
 ));
