Recommended Posts

Hey all,

 

I want to display the category list in my module like presta shop does.

 

Example:

After searching i have found the code to call the menu should be in the function getParentsCategories();

But I'm not able to call the list like i marked above.

 

Code i tried:

// Define id_category
$id_category = $this->category->id;

// Initialize object Category
$category = new Category((int)$id_category);

// Get array parent from the initialized object Category
$array_parent = $category->getParentsCategories();

So i need the php code to display the category menu in my module.

 

Thanks in advance!

With getParentsCategories, you only get the direct parents of a specific category, which is one branch of the tree. I expect you want the whole tree, so maybe better use the code they use in back office, catalog->products->edit product (associations tab)

 

from controllers/admin/AdminProductsController.php

 

 

$tree = new HelperTreeCategories('associated-categories-tree', 'Associated categories');
$tree->setTemplate('tree_associated_categories.tpl')
->setHeaderTemplate('tree_associated_header.tpl')
->setRootCategory($root->id)
->setUseCheckBox(true)
->setUseSearch(true)
->setSelectedCategories($categories);
 
$data->assign(array(
    'category_tree' => $tree->render()
));
 

 

For full use how to implement it, look in the file.

 

 

 

 

and then in your tpl file something like:

 

<div id="category_block">
{$category_tree}
</div>
 
 
 
My 2 cents,
pascal.

@PascalVG

 

Indeed i looked at the wrong function

 

i do not use a .tpl file for this part of back-office so i tried to put it into a variable which results in nothing.

 

using the following code in my datasheetpro.php also results in a empty variable.

$helper = new HelperTreeCategories('categories-treeview');
$category_tree = $helper->render();

echo 'TEST: '.$category_tree;

any idea ?

i found the following code:

 

Function:

public static function getCategoryTree($id_product,$id_lang){
	$root = Category::getRootCategory();
	$selected_cat = Product::getProductCategoriesFull($id_product, $id_lang);
	$tab_root = array('id_category' => $root->id, 'name' => $root->name);
	$helper = new Helper();
	$category_tree = $helper->renderCategoryTree($tab_root, $selected_cat, 'categoryBox', false, true, array(), false, true);
	return $category_tree;
}
$id_test = Configuration::get('PS_ROOT_CATEGORY');
$txt .= '<div> TEST: '.$this->getCategoryTree($id_test, $id_lang).' </div>

This gives me this as result:

but not a full tree for some reason ?

Hello!

 

Sorry for reopening this thread. I try to list category tree list, I use the code below, but this code list with radio buttons, and i need checkbox buttons, like in picture from first post. I dont want to use any .tpl file.

 

array(
           'type'  => 'categories',
           'label' => $this->l('Product Category'),
           'desc'    => $this->l('Product Category.'),  
           'name'  => 'category',
           'tree'  => array(
                'id' => 'category',
                'selected_categories' => array((int)Configuration::get('category')),
            )
        ),

 

Does anyone know how to do that?

Thank you!

Can you please try this one.

$selected_cat = Product::getProductCategoriesFull($id_product, $id_lang);
$root = Category::getRootCategory();
$tree = new HelperTreeCategories('kbmp-categories-tree');
$tree->setRootCategory($root->id)
    ->setInputName('kbmp_allowed_categories')
    ->setUseCheckBox(true)
    ->setUseSearch(false)
    ->setSelectedCategories((array) $selected_cat );
return $tree->render();

You're really really great man.

It works but it brings out this errors, do you know what are they?

Now, I only need to capture the selected value.
Could you give me any tip?

 

Thanks for your time.

Hello there,

I would like to create a custom module where I can display a list of available categories and be able to select multiple ones to then use them on front.

I used @ovy79ro code to display the list in back-office but I'll be glad to have some help to go further:

1. List is collapse by default, how can I expand it by default?

2. I used the checkbox property but I've got radio button and can select only one category instead of multiple ones

array(
  'type'  => 'categories',
  'label' => $this->l('Product Category'),
  'name'  => 'FEATURED_CATEGORIES',
  'tree'  => array(
    'id' => 'category',
    'selected_categories' => array((int)Configuration::get('category')),
  ),
  'use_checkbox' => true
),

3. I'm not sure how I'm suppose to save the selected categories, how to get selected categories in getConfigFormValues()?

protected function postProcess()
{
  $form_values = $this->getConfigFormValues();

  foreach (array_keys($form_values) as $key) {
    Configuration::updateValue($key, Tools::getValue($key));
  }
}

Thanks a lot for any help!

I have the answer for question 2, I didn't put the use_checkbox at the right place! 😓

array(
  'type'  => 'categories',
  'label' => $this->l('Featured categories'),
  'name'  => 'FEATURED_CATEGORIES',
  'tree'  => array(
    'id' => 'category',
    'selected_categories' => array((int)Configuration::get('category')),
    'use_checkbox' => true
  )
),

But it still collapse by default and I still don't have any clues on how to save the selected_categories.
