multiple sliders one page - Stash parse order and Playa

Question

Concept is to stash entry_ids of playa entries to pass to jquery-nivoslider call, so that both the slider div and the call will not have identical slider ID's resulting with conflict.

{exp:stash:set_list 
name="rehab_list" 
parse_tags="yes" 
trim="yes" 
parse_depth="4"
}

   {exp:channel:entries 
   channel="rehab" 
   url_title="{segment_3}" 
   limit="1"
   require_entry="yes"
    }

    {stash:rehab_entry_id}{entry_id}{/stash:rehab_entry_id}
    {stash:rehab_url_title}{url_title}{/stash:rehab_url_title}
    {stash:rehab_title}{title}{/stash:rehab_title}

{stash:playa_stash_test}test{/stash:playa_stash_test}

   {exp:stash:set_list:nested   
name="rehab_update_list"      
trim="yes"
parse_tags="yes" 
parse_depth="3"   
} 

    {exp:playa:parents 
    channel="rehab_update" 

    limit="10"}

          {stash:playa_test}test22{/stash:playa_test}
               0{stash:playa_entry}|{entry_id}{/stash:playa_entry}
                {stash:playa_title|{title}{/stash:playa_title}

                {image_uploads sort="asc"}{photo_images size="thumbnail"}     
                {stash:playa_entry_img}{photo:url}{/stash:playa_entry_img}
                {stash:playa_entry_img_label}photo_label}   {/stash:playa_entry_img_label}
        {/photo_images} {/image_uploads}

   {stash:playa_summary_update}{summary_update}{/stash:playa_summary_update}
   {stash:playa_materials_needed}{materials_needed}{/stash:playa_materials_needed}
   {stash:playa_steps_taken}{steps_taken}{/stash:playa_steps_taken}

    {/exp:playa:parents}
     {/exp:stash:set_list:nested}
  {/exp:channel:entries}
  {/exp:stash:set_list}

Answer 1

Set your var like this, using the trim parameter to remove whitespace and line breaks from the captured variable:

{exp:channel:entries channel="rehab" url_title="{segment_3}" limit="1" require_entry="yes"}
    {exp:stash:set name="update_ids" parse_tags="yes" trim="yes"}
        0{exp:playa:parents channel="rehab_updates" status="open" limit="10"}|{entry_id}{/exp:playa:parents}
    {/exp:stash:set}
{/exp:channel:entries}

Using the captured variable

Use the process="end" parameter to delay the parsing of the wrapped code block until the end of template parsing (i.e. after the variable has been set). Inside {exp:stash:parse} tag pairs, stash variables can be accessed as placeholders in the form {stash:my_var}, which saves you having to use parse="inward" when passing a tag as a parameter.

{exp:stash:parse process="end"}
    {exp:channel:entries channel="rehab"}
      {exp:playa:parents channel="rehab_updates" status="open" entry_id="{stash:update_ids}"}
        <script type="text/javascript">
          $(window).load(function() {
            $('#slider-{entry-id}').nivoSlider({});
          });
        </script>
      {/exp:playa:parents}
    {/exp:channel:entries}
{/exp:stash:parse}


{exp:stash:parse process="end"}
    {exp:playa:parents channel="rehab_updates" status="open" limits="10" entry_id="{stash:update_ids}"}
{/exp:stash:parse}

Answer 2

Snippets parse first, so your Stash tag {exp:stash:update_ids} gets read directly as it's written without being parse when that snippet code gets parsed. You can test that by only putting {exp:stash:update_ids} in your snippet.

Possible solution: Move that snippet code either into a Stash embed or regular EE embed.

Also, the limit parameter is just limit="10" not limits="10".

Answer 3

This is also possible and less complicated if you use sort="entry_id" orderby="asc" it would in essence accomplish what the idea was
