Prestashop subcategories returns null

[mat94600]

Hi,

 

After upgrading prestashop 1.5 to 1.6 i cannot view subcategories on new shop, with the old shop i have this structure on category page :

 

• Category name
  - subcategory 1 name
  - subcategory 2 name
  ...
• Category name 2
  - sucategory 2 name
  etc...
   

On new shop after upgrade, i only have :

• Category name
   

Category.tpl
 

<div id="subcategories">
		{foreach from=$subcategories item=subcategory name="subcategory"}

		<h2 class="title_block"><a href="{$link->getCategoryLink($subcategory.id_category, $subcategory.link_rewrite)|escape:'htmlall':'UTF-8'}" class="cat_name">{$subcategory.name|escape:'htmlall':'UTF-8'}</a></h2>
		{math equation="ceil(count/3)" count=$subcategory.subcategories|count assign=modulo}
		{$subcategory.subcategories|@debug_print_var} /* <=== HERE I DEBUG SUBCATEGORIES */
		{foreach from=$subcategory.subcategories item=subsubcategory name="subsubcategory"}
		
		{if $modulo==1 || $smarty.foreach.subsubcategory.iteration%$modulo==1 }
		<ul class="inline_list">
			{/if}
			<li class="clearfix">
				<a href="{$link->getCategoryLink($subsubcategory.id_category, $subsubcategory.link_rewrite)|escape:'htmlall':'UTF-8'}" class="cat_name">{$subsubcategory.name|escape:'htmlall':'UTF-8'}</a>
			</li>
			{if $smarty.foreach.subsubcategory.iteration%$modulo==0 || $smarty.foreach.subsubcategory.iteration==$subcategory.subcategories|count}
		</ul>
		{/if}
		{/foreach}
		<br class="clear"/>
		{/foreach}
	</div>
	{else}
		<div id="subcategories">
			{math equation="ceil(count/2)" count=$subcategories|count assign=modulo}
			{foreach from=$subcategories item=subcategory name="subcategory"}
			{if $modulo==1 || $smarty.foreach.subcategory.iteration%$modulo==1 }
			<ul class="inline_list_2">
				{/if}
				<li class="clearfix">
					<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>
				{if $smarty.foreach.subcategory.iteration%$modulo==0 || $smarty.foreach.subcategory.iteration==$subcategories|count}
			</ul>
			{/if}
			{/foreach}
			<br class="clear"/>
		</div>
	{/if}

As you can see, i have debugged {$subcategory.subcategories} and it returns "null" on front. so why it's not returns subcategories , so my question :

Why it's returns null on 1.6, something has changed on the controller of the category? 

 

thank you

Check inside database your ps_category table and subcategories 'id_parent' row. Probably you have some problem with id_parent.
