Subcategories links inside a subcategory?

[juanmlg]

I want to add the subcategories menu of a category inside each subcategory of this category (similar to a tab menu inside each category) . I know I need to modify the category.tpl file, and the code maybe similar to:

 

{foreach from=$subcategories item=subcategory}
   <li >
	 <a href="{$link->getCategoryLink($subcategory.id_category, $subcategory.link_rewrite)|escape:'htmlall':'UTF-8'}" class="cat_name">{$subcategory.name|escape:'htmlall':'UTF-8'}</a>

   </li>
  {/foreach}

 

 

But this code doesnt works inside a subcategory,needs some modifications.

 

You can see more info about my question here: http://www.prestashop.com/forums/topic/228708-subcategories-menu-inside-a-subcategory/page__p__1123841#entry1123841

 

 

any help?

 

Thanks so so much.

nothing?

I'm not sure i completely understood what you want to achieve. Do you want to get a list of the sibling categories of the current ones? I mean, brothers and sisters of the current subcategory?

Yes! Exactly. I want to show the brothers and sisters subcategories of the current subcategory for make a "tab menu".

[NemoPS]

Ok, let's try something:

 

In category.tpl, add this line where you want the list to appear:

 

{hook h='category' id_category=$category->id}

 

We are creating a new hook and passing the category ID as a parameter.

 

Now create a new module, add registerHook('category') in the install function, then create hookCategory like this

 

public function hookCategory($params)
{
   $id_parent = $params['id_parent'];
   $parent_category = new category($id_parent);
   $children = $parent_category->getSubcategories($this->context->language->id);
// finally, assign them to smarty and return a tpl

}

 

Of course, you might want to add some kind of switch to target specific categories only, this is just a rough idea

Thanks so much! I am going to try this. It seems difficult but not impossible. Thanks again.

Hi,

I'm trying to apply the Nemo1 tips with some modifies.

I add in category.tpl the following row

{hook h='category' id_category=$subcategory.id_category}

Then I create a module with this function

public function hookCategory($params) {
		$id_category = $params['id_category'];
		$category[] = new Category($id_category);
		global $smarty;
		$smarty->assign(array('category'=> $category));

		return $this->display(__FILE__, 'mymodule.tpl');
	}

and I make this tpl file

{if isset($category)}
	{$category.name}
{/if}

But when I reload the page I have this error

"Fatal error: Cannot use object of type Category as array in..."

Please someone can tell me what wrong?

Thanks

[NemoPS]

You have to use $category->name

[airbag76]

Hi Nemo,

thanks for your reply.

But I've still problem...

Here the modificated code

 - In category tpl:

{hook h='category' category=$subcategory}

 - In the new module:

public function hookCategory($params) {
		$category = $params['category'];
		$children = $category->getSubcategories($this->context->language->id);
		...other code here


		return $this->display(__FILE__, 'subcategoriesmenuoncategory.tpl');
	}

but when I reload the page I have a fatal error:

 

"Fatal error: Call to a member function getSubcategories() on a non-object in..."

 

I'm passing the object "category", why I can't invoke the metode "getSubcategories"?

 

Thanks

[NemoPS]

Are you sure $subcategory represents a valid category object there? if not you have to instantiate a new one using new Category()... etc

[airbag76]

Hi Nemo1,

I resolved so:

public function hookCategory($params) {
		$category = $params['category'];
		$id_category = $category['id_category'];
		$parent_category = new Category($id_category);
		$children = $parent_category->getSubcategories($this->context->language->id);
		// finally, assign them to smarty and return a tpl
		global $smarty;
		$smarty->assign('category', $category);
    	        $smarty->assign('children', $children);
        	$this->context->controller->addCSS($this->_path.'css/menucategory.css');
		return $this->display(__FILE__, 'menucategory.tpl');
	}

It's strange, because I passed an object.

Thanks for all

[NemoPS]

Small advice: do not use globals, use $this->context->variablename instead, smarty in this case

[airbag76]

Hi Nemo,

first thank for all helpful tips.

Now I have a problem with css. T_T

I tried to add CSS in any way but seems it ignores me.

I tried with:

Tools::addCSS(($this->_path).'css/menucategory.css', 'all');

and so with:

$this->context->controller->addCSS(($this->_path).'css/menucategory.css', 'all');

and also with:

public function hookHeader() {
		$this->context->controller->addCSS(($this->_path).'css/menucategory.css', 'all');
	}

I cleared the cache and compile smarty folders but nothing, my css isn't loaded.

Any suggest?

My prestashop version is 1.5.6.2

 

Thanks

[vekia]

is your module associated with hookdisplayHeader ?

[airbag76]

Hi Vekia,

I think no, how I can see it?

I added in category.tpl "{hook h='category' category=$subcategory}" and than I created a new module with this function:

public function hookCategory($params) {
		$category = $params['category'];
		$id_category = $category['id_category'];
		$parent_category = new Category($id_category);
		$children = $parent_category->getSubcategories($this->context->language->id);
		$this->context->smarty->assign('category', $category);
		$this->context->smarty->assign('children', $children);
 		if ($this->psversion()==5 || $this->psversion()==6){
 			$this->context->controller->addCSS(($this->_path).'css/menucategory.css', 'all');
 		} else {
 			Tools::addCSS(($this->_path).'css/menucategory.css', 'all');
 		}
		return $this->display(__FILE__, 'menucategory.tpl');
	}

I forgot something?

 

Thanks

[NemoPS]

Of course, that method must be used inside displayHookHeader in order to work properly

[vekia]

go to modules > positions and transplant your module to hookdisplayHeader (use anchor button to open transplant form)

[airbag76]

Thanks guys, now it work very fine

Someone is so kindly to explain me why the method must be used inside displayHookHeader.

Thanks for all

[vekia]

displayhookheader is a place to include css / js librariers

all other hooks are wrong place to include css / js files

 

if you will check page structure you will see that libraries are included in <head></head> section of your website

not in left / right  columns or sth

Hi,

 

I follow the code above. But I couldn't get it work. I can't see any output in my category page.

 

Could you paste all code / files that you have modified?

 

Thanks in advanced!!!

[stejob]

Hi.

 

I would also like to see all code.

 

I tried to do this. But I guess I don't know how to make the module exactly. I cant get it to install with just that code.

 

Thanks in advance
