Testing for Category Header/Footer content

[lesliekirk]

I need a way to test for Category Header (or Footer) content and if the field is empty display alternate content. I thought I had figured it out but of course not

 <mvt:if expr="ISNULL l.settings:customfield_names:cmp_cssui_pchdft:header">
<p class="tableheader" style="margin-left:10px;">&mvt:category:name;</p>
<mvt:else>

<div class="ctgy-header">
<mvt:item name="prod_ctgy_hdft" param="ctgy_header" />
</div>
</mvt:if>

What am I doing wrong?

I don't think cmp_cssui_pchdft is a valid custom field name. Since the header content is rendered from an mvt:item tag, you may need to put the tag inside an mvt:capture. That will put the content into a variable, and then you can check whether that variable contains any text.

I've stumbled upon the same thing Kent did, I forget how or why, but its an easy way for getting info logically from stuff like that. Even combinations of stuff like that. Just output the mvt tag in question within mvt:capture. Now you can do logic on the variable that you choose.

<mvt:capture variable="g.man_this_is_cool"><mvt:item name="prod_ctgy_hdft" param="ctgy_header" /></mvt:capture>

&mvt:global:man_this_is_cool; is the contents of the category header.

Obviously you can run checks on it. like if g.man_this_is_cool NE '' then bla bla bla kazam.

Hope all that helps and you get some wild and crazy ideas.

Hey Colin, I sort of understand but sort of don't (what else is new?).

So are you saying I test for the content but output it using "&mvt:global:man_this_is_cool;" instead of the <mvt:item name="prod_ctgy_hdft" param="ctgy_header" /> tag?

[lesliekirk]

To answer my own question (and for those who might want to do this too):

<mvt:capture variable="g.man_this_is_cool"><mvt:item name="prod_ctgy_hdft" param="ctgy_header" /></mvt:capture>
<mvt:if expr="g.man_this_is_cool NE ''">
<div class="ctgy-header">
&mvt:global:man_this_is_cool;
</div>
<mvt:else>
<p class="tableheader" style="margin-left:10px;">&mvt:category:name;</p>
</mvt:if>

Thank you Colin!
