If several instances have same values, list only once

(@filespit)

Hello there,

I’m having some difficulties with a PHP script using the Simple Fields plugin. I’m still a rookie at PHP so help would be much appreciated.

On my website I’m listing retailers using a set of six fields, where I add the retailer’s name, street adress, zip code, e-mail, city and country. Several retailers are located in the same country, and some in the same city.

Since some retailers are located in the same country, I only want to list each country once, and the same goes for cities. How do I solve this?

My code;

<div id="buy-list">
	<ul>
		<?php $store = simple_fields_get_post_group_values($post->ID, "Store", true, 2); ?>
		<?php foreach ($store as $store_value) : ?>
		<li class="buy-country">
			<span class="buy-country-span">
				<?php echo $store_value["Country"] ?>
			</span>
			<ul>
				<li class="buy-city">
					<span>
						<?php echo $store_value["City"] ?>
					</span>
					<ul>
						<li class='buy-store'>
							<span>
								<?php echo $store_value["Retailer"] ?>
							</span>
							<ul>
								<li class='buy-info'>
									<span>
										<?php echo $store_value["Retailer address"] ?><br />
										<?php echo $store_value["Retailer phone"] ?><br />
										<a href="mailto:<?php echo $store_value["Retailer email"] ?>"><?php echo $store_value["Retailer email"] ?></a>
									</span>
								</li>
							</ul>
						</li>
					</ul>
				</li>
			</ul>
		</li>
		<?php endforeach; ?>
	</ul>
</div>

perhaps something like this:

<div id="buy-list">
	<ul>
		<?php $store = simple_fields_get_post_group_values($post->ID, "Store", true, 2); ?>
		<?php
		$prev_country = "";
		foreach ($store as $store_value) : ?>
		<li class="buy-country">
			<?php if ($prev_country !== $store_value["Country"] ) { ?>
				<span class="buy-country-span">
					<?php echo $store_value["Country"] ?>
				</span>
				<?php
				$prev_country = $store_value["Country"];
			} ?>
			<ul>
				<li class="buy-city">
					<span>
						<?php echo $store_value["City"] ?>
					</span>
					<ul>
						<li class='buy-store'>
							<span>
								<?php echo $store_value["Retailer"] ?>
							</span>
							<ul>
								<li class='buy-info'>
									<span>
										<?php echo $store_value["Retailer address"] ?><br />
										<?php echo $store_value["Retailer phone"] ?><br />
										<a href="mailto:<?php echo $store_value["Retailer email"] ?>"><?php echo $store_value["Retailer email"] ?></a>
									</span>
								</li>
							</ul>
						</li>
					</ul>
				</li>
			</ul>
		</li>
		<?php endforeach; ?>
	</ul>
</div>

Thank you Pär, that helped a bit but it’s still not right.

This way each country only displays one city in separate <div class=”buy-country”> tags, and makes the html code look like this.

<div id="buy-list">
  <ul>
    <li class="buy-country">
      <span>Sweden</span>
      <ul>
        <li class="buy-city">
          <span>Gothenburg</span>
        </li>
      </ul>
    </li>
    <li class="buy-country">
      <span>Sweden</span>
      <ul>
        <li class="buy-city">
          <span>Stockholm</span>
        </li>
      </ul>
    </li>
    <li class="buy-country">
      <span>Denmark</span>
      <ul>
        ...
      </ul>
    </li>
  </ul>
</div>

The code only displays the first “buy-country” instance, the rest that have the same country are hidden. I want the html code to look like this;

<div id="buy-list">
  <ul>
    <li class="buy-country">
      <span>Sweden</span>
      <ul>
        <li class="buy-city">
          <span>Gothenburg</span>
        </li>
        <li class="buy-city">
          <span>Stockholm</span>
        </li>
      </ul>
    </li>
    <li class="buy-country">
      <span>Denmark</span>
      <ul>
        ...
      </ul>
    </li>
  </ul>
</div>
