If statement inside a loop?

Question

I am using the store finder module, and am trying to insert a "title" for each "state". If I have 20 stores in a certain state, I would only like to display the "title" once. Is there any way this could be done with an if statement? to kind of break the loop?

{exp:store_locator:stores}                       
<ul>
        <li style="width:260px; padding-right:20px; float:left; height:100px;">
            <h5>{name}</h5>

            {if address_line1 !=""}         
            {address_line1}<br/>
            {/if}

            {city}, {state} 
            {postal_code}<br />

            {if phone != ""}
            <strong>Phone:</strong> {phone}
            <br/>
            {/if}

            {if url != ""}
            <strong>Website:</strong> <a href="http://www.{url}" target="_blank">{url}</a>        <br/>
            {/if}
        </li>
    </ul>

    {/exp:store_locator:stores}

There is an add-on from EE Garage that I have used to do that on a store finder before.

It's called NSM Channels. http://ee-garage.com/nsm-channels

Not sure if there is something similar on Devot-ee.com for free, but I know this works.

You can use stash lists. Store the state separately. On output order by the unique states and use a nested get_list to get the entries/stores per state.

(example from Croxton slide: Stash core principles )

{exp:stash:set_list name="my_stores" parse_tags="yes" scope="site"}
  {exp:store_locator:stores}
    {stash:item_state}{state}{/stash:item_state}
    {stash:item_name}{name}{/stash:item_name}
    {stash:item_info}
        {address_line1}<br>
        {city}, {state}<br>
        {postal_code}
    {/stash:item_info}
  {/exp:store_locator:stores}
{/exp:stash:set_list}

Then retrieve the unique states, and accompanying stores via:

{exp:stash:get_list name="my_stores" orderby="item_state" unique="item_state" scope="site"}
  <h2>{item_state}</h2>
  {exp:stash:get_list:nested name="my_stores" orderby="item_name" scope="site"
    match="#^{item_state}$#" 
    against="item_state"
    prefix="result"}
      <h3>{result:item_name}</h3>
      {result:item_info}
  {/exp:stash:get_list:nested}
{/exp:stash:get_list}

Note: if you use conditionals, like in your example for address_line1, etc., i'ld suggest adding the parameter parse_conditionals="yes" in set_list.

I think you'll need to enable PHP in the template, set it to parse on input and use it to store the value of {state} on each iteration of the loop, at the top of the loop check to see if state is equal to itself or not, if not the write out the value as a heading. :)

It's possible you might be able to achieve the same result with Stash but I'm not really familiar with that. :)
