Get the parent category custom field on deep level child category

[tammu]

I have my parent and child category set up like below

Gifts > Toys & Games > Toys > Plush
Gifts > Toys & Games > Toys > Marvel
Gifts > Toys & Games > Games > Puzzles
Gifts > Toys & Games > Games > Cards

I have a category custom field called header_image which holds a promo image for that particular category. What I am trying to do access this image on child categories so I can use it as a fall back image in case these categories don't have one.

I have tried using the code below but was only successful up to the first level of child category

<mvt:item name="toolkit" param="childof|parentfound|g.Category_Code" />
<mvt:if expr="g.parentfound">
<mvt:item name="toolkit" param="customcategoryc|catheadimg|l.all_settings: childof:code|header_image" />
#cgty_header_image{background-image:url('&mvt:global:basehref;&mvte:global:catheadimg;');background-repeat:no-repeat}
</mvt:if>

If there is a replacement for toolkit function, I am fine with it.

Thanks

Here is one way to accomplish the feature using Miva template code:

<mvt:comment> One Level Up </mvt:comment>
<mvt:if expr="l.settings:category:parent_id NE 0">
    <mvt:do name="l.result" file="g.Module_Library_DB" value="Category_Load_ID( l.settings:category:parent_id, l.settings:next_parent_category )" />
    <mvt:comment> Two Levels Up </mvt:comment>
    <mvt:if expr="l.settings:next_parent_category:parent_id NE 0">
      <mvt:do name="l.result" file="g.Module_Library_DB" value="Category_Load_ID( l.settings:next_parent_category:parent_id, l.settings:next_next_parent_category )" />
      <mvt:comment> Three Levels Up </mvt:comment>
      <mvt:if expr="l.settings:next_next_parent_category:parent_ id NE 0">
        <mvt:comment> Add a fourth level check here if needed </mvt:comment>
      <mvt:else>
        <mvt:item name="customfields" param="Read_Category_ID( l.settings:next_next_parent_category:id, 'header_image', l.settings:next_next_parent_category:customfield_v alues:customfields:header_image )" />
        three header_image = &mvt:next_next_parent_category:customfield_valu es: customfields:header_image;
      </mvt:if>
    <mvt:else>
      <mvt:item name="customfields" param="Read_Category_ID( l.settings:next_parent_category:id, 'header_image', l.settings:next_parent_category:customfield_values :customfields:header_image )" />
      two header_image = &mvt:next_parent_category:customfield_values:cu sto mfields:header_image;
    </mvt:if>
<mvt:else>
    <mvt:item name="customfields" param="Read_Category_ID( l.settings:parent_category:id, 'header_image', l.settings:parent_category:customfield_values:cust omfields:header_image )" />
    one header_image = &mvt:parent_category:customfield_values:customf iel ds:header_image;
</mvt:if>

The code is checking for the parent_id value then using the Category_Load_ID function to get the parent_id and if there is another partent_id it will continue for three levels. If in those three levels the parent_id is 0 the code will get the custom field.

You can probably code it to go through a while loop that checks if the parent_id is 0 if you wanted it to be a bit more dynamic.

We have a similar situation and our solution was to have a concept of 'main parent category' . Each product has a custom field where that value (category code) is populated. Therefore, all we need to do is call that custom field, load the category data structure ( category_load_code() ) and gather what we need. In your case, you could just use that custom field data directly in:

<mvt:item name="customfields" param="Read_Product_Code( 'product_code', 'custom_field_code', l.settings:customfields )" />
