[SOLVED] Banging my head against a wall... Nested foreach and multidimensional arrays

[cableguy1115]

Hello,

 

I have this code:

<ul>	{assign var='all_categories' value=Category::getCategories(Context::getContext()->language->id)}	{foreach from=$all_categories name=outer item=pagecat key=key1}			{foreach from=$pagecat name=mid item=subcat key=key2}					{foreach from=$subcat name=inner item=innercat key=key3}								{assign var="idca" value=$innercat.id_category}				{assign var="idpa" value=$innercat.id_parent}				{assign var="name" value=$innercat.name}				{assign var="lirw" value=$innercat.link_rewrite}				{assign var="lvdp" value=$innercat.level_depth}								{if ($idpa == $id_category && $idpa != $idca) || ($idpa == $id_category_parent && $idpa != $id_category && $lvdp > 2)}					{if $lirw neq 'man' && $lirw neq 'woman'}						<li><a href="/{$lang_iso}/{$idca}-{$lirw}"><span>{$name}</span></a></li> 					{/if}				{else}				{/if}							{/foreach}					{/foreach}			{/foreach}</ul>

It's supposed to explode the "all_categories" array:

Array(    [0] => Array        (            [1] => Array                (                    [infos] => Array                        (                            [id_category] => 1                            [id_parent] => 0                            [id_shop_default] => 1                            [level_depth] => 0                            [nleft] => 1                            [nright] => 58                            [active] => 1                            [date_add] => 2015-10-21 16:51:55                            [date_upd] => 2015-10-21 16:51:55                            [position] => 0                            [is_root_category] => 0                            [id_shop] => 1                            [id_lang] => 1                            [name] => Raíz                            [description] =>                             [link_rewrite] => raiz                            [meta_title] =>                             [meta_keywords] =>                             [meta_description] =>                         )                )        ))

It works perfectly until you get to the page that displays the 3rd subcategory, then it goes blank.

 

Sample: http://www.bustomshoes.com/es/12-modelos

HINT: Select the model on the left, then on the right select the gender.

 

I've been trying for two days now to create a third condition, something like "OR IF the SECOND parent of THIS category is the same same, display all categories, etc.". Basically, what I've been trying is to find a way to get the second parent (grandfather) of the curent category, then I could just simply echo all the entries that fulfill that condition.

 

Helpppp! (

If it goes blank you have an error.

 

So you should enable development mode (https://www.prestashop.com/forums/topic/224525-how-to-turn-on-error-reporting-for-debug-information-blank-page-500-internal-server-error/) or look in the error log of the server to see what that error is. After that solving the problem will be easier.

My final code to be able to get the grandfather category ID (parent parent ID):

 

In Category.tpl :

 

Notice $parents[1] array. $parents[0] would give the parent ID, [1] grandparent, [2] great grand parent, and so on....

<ul>
	<li><span>Models</span>
		<ul>
			{assign var=gf value=$parents[1].id_parent} // <-- THIS LINE stores grandparent ID (delete this comment)
			{assign var='all_categories' value=Category::getCategories(Context::getContext()->language->id)}
			
			{foreach from=$all_categories name=outer item=pagecat key=key1}
			
				{foreach from=$pagecat name=mid item=subcat key=key2}
				
					{foreach from=$subcat name=inner item=innercat key=key3}
					
					{assign var="idca" value=$innercat.id_category}
					{assign var="idpa" value=$innercat.id_parent}
					{assign var="name" value=$innercat.name}
					{assign var="lirw" value=$innercat.link_rewrite}
					{assign var="lvdp" value=$innercat.level_depth}
					
					{if ($idpa == $id_category && $idpa != $idca) || ($idpa == $id_category_parent && $idpa != $id_category && $lvdp > 2) || ($idpa == $gf && $lvdp == '3')}
						{if $lirw neq 'man' && $lirw neq 'woman'}
							<li><a href="/{$lang_iso}/{$idca}-{$lirw}"><span>{$name}</span></a></li> 
						{/if}
					{/if}
					
					{/foreach}
					
				{/foreach}
				
			{/foreach}
			
		</ul>
	</li>
</ul>

In CategoryController.php, modify the initContent() function and add the lines:

$array_parent = $this->category->getParentsCategories();   // <-- THIS LINE (delete this comment)
		
        $this->context->smarty->assign(array(
            'category'             => $this->category,
            'description_short'    => Tools::truncateString($this->category->description, 350),
            'products'             => (isset($this->cat_products) && $this->cat_products) ? $this->cat_products : null,
            'id_category'          => (int)$this->category->id,
            'id_category_parent'   => (int)$this->category->id_parent,
	    'parents' 		   => $array_parent,   // <-- THIS LINE (delete this comment)
	    'return_category_name' => Tools::safeOutput($this->category->name),
            'path'                 => Tools::getPath($this->category->id),
            'add_prod_display'     => Configuration::get('PS_ATTRIBUTE_CATEGORY_DISPLAY'),
            'categorySize'         => Image::getSize(ImageType::getFormatedName('category')),
            'mediumSize'           => Image::getSize(ImageType::getFormatedName('medium')),
            'thumbSceneSize'       => Image::getSize(ImageType::getFormatedName('m_scene')),
            'homeSize'             => Image::getSize(ImageType::getFormatedName('home')),
            'allow_oosp'           => (int)Configuration::get('PS_ORDER_OUT_OF_STOCK'),
            'comparator_max_item'  => (int)Configuration::get('PS_COMPARATOR_MAX_ITEM'),
            'suppliers'            => Supplier::getSuppliers(),
            'body_classes'         => array($this->php_self.'-'.$this->category->id, $this->php_self.'-'.$this->category->link_rewrite)
        ));
