public function getCategoriesArray() {

    $categoriesArray = Mage::getModel('catalog/category')
            ->getCollection()
            ->addAttributeToSelect('name')
            ->addAttributeToSort('path', 'asc')
            ->load()
            ->toArray();

    $categories = array();
    foreach ($categoriesArray as $categoryId => $category) {
        if (isset($category['name']) && isset($category['level'])) {
            $categories[] = array(
                'label' => $category['name'],
                'level'  =>$category['level'],
                'value' => $categoryId
            );
        }
    }

    return $categories;
}

to add in form

 $fieldset->addField('categories', 'multiselect', array(
            'label' => $this->__('Categories'),
            'name' => 'categories',
            'values' => $this->getCategoriesArray(),
        ));

    yes i did and i get all categories in multiselect field but I want to show categories as same as categories tree just like in edit product section in magento default. Hope you understand Nov 5, 2015 at 5:24
  • for that you have to look this block Mage_Adminhtml_Block_Catalog_Product_Edit_Tab_Categories and this phtml file catalog/product/edit/categories.phtml Nov 5, 2015 at 5:34
  • Where do I put these, because I don't have for it. Oct 7, 2016 at 7:33

I just had the same Problem. I was using the same solution you have linked and couldn't get the categories to show up.

Two things that were important:

  1. Check your categories.phtml especially the Javascript part and be sure that all classes in the JS are correct.
  2. At least in Magento 1.9 you have to be sure, that extJS is loaded. Use one of the following ways to use extJS:

a) In your controller use this:

$this->getLayout()->getBlock('head')->setCanLoadExtJs(true);

b) In your layout xml use this:

<reference name="head">
    <action method="setCanLoadExtJs">
        <value>1</value>
    </action>
</reference>
