php - Magento Custom Module: multiple Image Uploader in adminhtml form -


i have created adminhtml module working fine. in create new item form there 4 field name , images, url , email id;

i have used file uploader upload images . working fine not able upload multiple images.

is possible have multiple image uploader? here simple image uploader code.

  if(isset($data['image']) && $data['image'] != ''){         $finderlink = mage::getbaseurl(mage_core_model_store::url_type_media) .'finder/store_locator/'.$data['image'];         $findername = $data['image'];         $fieldset->addfield('imagelabel', 'label', array(             'label' => mage::helper('finder')->__('location image'),             'name'  =>'image',             'value'     => $finderlink,             'after_element_html' => '<img src="'.$finderlink .'" alt=" '. $findername .'" height="120" width="120" />',         ));          $fieldset->addfield('image', 'image', array(             'label' => mage::helper('finder')->__('change image'),             'required' => false,             'name' => 'image',         ));      }else{         $fieldset->addfield('image', 'image', array(             'label' => mage::helper('finder')->__('image'),             'required' => false,             'name' => 'image',         ));     }

enter image description here

i need have multiple image uploader in custom module.

you need create custom renderer image field. create class in module:

<?php  class [namespace]_[module]_block_adminhtml_[entity]_helper_image extends varien_data_form_element_image{     //make renderer allow "multiple" attribute     public function gethtmlattributes(){         return array_merge(parent::gethtmlattributes(), array('multiple'));     } }

now @ top of _prepareform (where add fields) add line before adding field:

$fieldset->addtype('image', '[namespace]_[module]_block_adminhtml_[entity]_helper_image');

or if want "politically correct" add way:

$fieldset->addtype('image', mage::getconfig()->getblockclassname('[module]/adminhtml_[entity]_helper_image'));

this tell magento in current fieldset, fields type image should rendered own class.

now can add field similar how did it:

$fieldset->addfield('image', 'image', array(             'name'      => 'image[]', //declare array. otherwise 1 image uploaded             'multiple'  => 'multiple', //declare input 'multiple'             'label'     => mage::helper('helper_alias')->__('image'),             'title'     => mage::helper('helper_alias')->__('image'),             'required'  => true,         ));

that's it.
don't forget replace placeholders ([module] , others) values.

this way override/add input type want. create own class should extend original input class (or varien_data_form_element_abstract if add new one) , declare @ top of _prepareform
