Excluding Categories in Newsletters

[srqwebguy]

Hi,

I'm reaching out because after setting this up; I am unable to make a newsletter that excludes the category title if there's no article for the day.

I have a feeling that <vte if=> would come into play, but not sure how to input it.

I have tried to embed the sample code here, but it is causing a 500 Server error, even when I embed in CODE tags....

Appreciate any help! Thanks.

Update - I was able to get it to accept the code using the PHP tags in the post below - but for some reason any other text in that post generated a server error. Strange.....

PHP Code:

[CODE]<vte:template>
<vte:include file="{VIVVO_TEMPLATE_DIR}box/topad.tpl" />
<vte:box module="box_sections">
                            <vte:template>
                                <vte:for from="{categories}" step="1" key="category_index">
                                    <vte:foreach item = "category" from = "{categories}" loop="1" start="{category_index}">
                                        <h1><vte:value select="{category.get_category_name}" /></h1>
                                        <vte:box module="box_article_list">
                                            <vte:params>
                             <vte:param name="search_search_date" value="1" />
                             <vte:param name="search_before_after" value="1" />
                             <vte:param name="search_sort_by" value="created" />

                                            </vte:params>

This error can be caused by a too restrictive setup of the mod_security module, in case it's installed on your server. So, first I would suggest to contact your server administrator and ask him to check the mod_security rules for you.

Thanks Jasmina, but I think you might have misunderstood. The 500 Server error was on THIS site, vivvo.net, when I was trying to post the code now found in the 2nd post in this thread. The problem we are having is using the newsletter module.

When we send an email, it lists categories regardless of whether there is a story listed or not. How can we override this so that it the email does not show an empty category? The template code we are using is listed above.

Thanks.

This will do the trick for ya. Simply move the H1 down into a if check within the articles box module. Check the articles array and only print it out if there are articles..

<vte:template> 
	<vte:include file="{VIVVO_TEMPLATE_DIR}box/topad.tpl" /> 
		<vte:box module="box_sections"> 
			<vte:template> 
				<vte:for from="{categories}" step="1" key="category_index"> 
					<vte:foreach item = "category" from = "{categories}" loop="1" start="{category_index}"> 
						<vte:box module="box_article_list"> 
							<vte:params> 
								<vte:param name="search_search_date" value="1" /> 
								<vte:param name="search_before_after" value="1" /> 
								<vte:param name="search_sort_by" value="created" /> 
								<vte:param name="search_order" value="descending" /> 
								<vte:param name="search_limit" value="5" /> 
								<vte:param name="search_cid" value="{category.id}" /> 
								<vte:param name="exclude_printed" value="true" /> 
							</vte:params> 
							<vte:template>
								<vte:if test="{article_list}">
									<h1><vte:value select="{category.get_category_name}" /></h1> 						
									<ul> 
										<vte:foreach item = "article" from = "{article_list}"> 
											<vte:include file="{VIVVO_TEMPLATE_DIR}summary/default.tpl" /> 
										</vte:foreach> 
									</ul> 
								</vte:if>								
							</vte:template> 
						</vte:box> 
					</vte:foreach> 
				</vte:for> 
			</vte:template> 
		</vte:box> 
	<vte:include file="{VIVVO_TEMPLATE_DIR}box/sideads.tpl" />                       
</vte:template>

That worked! Thank you.
