How to show a channel image gallery if there is more than 1 images inside?

{exp:channel:entries channel="journal" limit="1" url_title="{segment_3}" disable="categories|member_data|pagination|trackbacks" cache="yes" refresh="512640"}  

{if image:total > 1}

<div class="mini-page-wrapper responsive-image bg-accent-darkest offset-parent">
{exp:channel_images:images entry_id="{entry_id}" limit="1" field="journal_images"}
    <!-- ..code for my image gallery.. -->
{/exp:channel_images:images}        
</div>

{/if}

{/exp:channel:entries}

the conditional global variable {if image:total > 1} should be placed after {exp:channel_images} but i need to hide the parent div class too.. so..

1

I have a solution below for you so what I have done is test 3 things

1.) If there is more than 1 image do the gallery code only displaying the div html if the gallery exists so the first time it outputs the opening div the last image in the loop outputs the closing div.

2.) If there is only 1 image I have you a space to do other code.

3.) If there aren't any images i gave you a space for code.

Hope this helps!

       {exp:channel:entries channel="journal" limit="1" url_title="{segment_3}" disable="categories|member_data|pagination|trackbacks" cache="yes" refresh="512640"}  
            {exp:channel_images:images entry_id="{entry_id}" limit="1" field="journal_images"}
                {if "{image:total}" > 1}
                   {if "{image:count}¶" == "1"}
                     <div class="mini-page-wrapper responsive-image bg-accent-darkest offset-parent">
                  {/if}
                       <!-- ..code for my image gallery.. -->
                  {if "{image:total}" == "{image:count}"}
                     </div>
                  {/if}
               {if:elseif "{image:total}" == "1"}
                     <!-- Code displayed for only a single image -- >
               {/if}
               {if image:no_images}
                    <!-- Code displayed for no image results
               {/if}
           {/exp:channel_images:images} 
        {/exp:channel:entries}

  • I created this solution with the mindset of the div.offset-parent being a parent div to the images loop not being looped every time. If that is not the case and you need that div looped every time an image is displayed just delete the if statements that are wrapping the html. – mattsidjohn Mar 27 '14 at 2:08

Are you saying you want to conditionally hide the parent div based on the total count, in addition to showing specific gallery code if count > 1?

If so, can you move the div within the channel images tag and use the conditional twice - first to add a class to hide said div and second to show specific gallery code? Not entirely sure what you're after here.

dear Jessica D'Amico, thank you for your reply but I got it working just with embedding template technique:

{exp:channel:entries channel="journal" limit="1" url_title="{segment_3}" disable="categories|member_data|pagination|trackbacks" cache="yes" refresh="512640"}  
{exp:channel_images:images entry_id="{entry_id}" field="journal_images"}
    {if "{image:total}" > 1}
        {if "{image:total}" == "{image:count}"}
                {embed="moyseion:journal/_slideshow-em" entry_id="{entry_id}"}
        {/if}
    {/if}
{/exp:channel_images:images} 
{/exp:channel:entries}

and this is my embed template:

<!--altre foto-->
<div class="mini-page-wrapper" data-role="story-part" id="part-2">
  <section class="mini-page mini-page-semicompact">
    <header class="block-stack">

      </p>

<ul data-role="slideshow-em-tray slideshow-lazy" data-set-url="" class="slideshow-em-tray reset-list offset-parent clearfix">

        </figcaption>
        {/if}

    </li>
