This is somewhat related to this thread.

Scenario: The clients blog posts can have 0-10 images. The images are ancillary to the text so displaying any more than 2-3 overwhelms the text. Since I can’t do what I wanted in the above link, I’ve hardwired the number of images brought in through the reverse_related entries tag. If there are more than that hardwired number, I want to include a link to a gallery showing all the images with their captions. The images are in their own weblog as single entries.

Need: Have to get the total number of images in the gallery weblog that are related to the currently displayed entry and condition this against the display limit. Something like this…

{reverse_related_entries weblog="w_gallery" orderby="date" sort="asc" limit="3"}
{image}
{caption}
{if current_count == "3" AND current_count < total_related_entries }
Here’s a link to the image gallery for this post.
{/if}
{/reverse_related_entries}

Have searched but couldn’t find if there’s variables that will work or can do this.
Any insights will be greatly appreciated.

Ya, me bad…B U M P

Is there a way to do this conditional and get the total entries I need…Query, PHP, standard EE, anything?

According to the docs, nearly any of the weblog entries variables can be used; so why not just use count and total_results?

Those give the count or total that are being brought in for display (the limit), not the grand total that are related. Or, at least that’s the way they’ve worked in my testing code.

Derek…I need the total related entries. The total_results, as I’ve tried it, gives me the total for the results returned as set by the limit parameter. If my limit is set to 3 and there are 10 images related to the entry, the total_results has given me 3. I need the 10.
Make sense?

Ok, yes, that’s clear.  You might experiment with template debugging turned on so you can see how much, if any, the memory required jumps (or execution time) if you just leave off the limit= parameter, and only display entries if the count < 3.  Then total_results will be the total number of reverse relationships, which is what you are looking for.

{reverse_related_entries weblog="w_gallery" orderby="date" sort="asc"} 
{if count < 4}
    {image} 
    {caption} 
    {if count == “3” AND total_results > 3} 
        Here’s a link to the image gallery for this post. 
    {/if}
{/if}
{/reverse_related_entries}

Ahhhh yes…I can’t imagine it will be too bad as there will probably never be more than 10-15 related entries for any post but I’ll check. Thanks Derek!

Ultimately I also want to use a field from the weblog so the editor can set the limit based on length of post but that requires a different parse order. Mentioned it to Paul a while back.
