<h3>Filter</h3>
<p>Our database can be searched by sending a <code>GET</code> request to <code><?php
echo $baseurl;
?>
api/filter/</code> with filter commands as variables. Each request will return the number of trails returned as <code>countReturned</code> and the total number of trails matched by the query as <code>totalMatched</code>. Note, you must set <code>offset</code> and <code>count</code>. For example, <code>GET <?php
echo $baseurl;
?>
api/filter/?by=city&city=Albuquerque&offset=0&count=6 </code> returns the following information in JSON:</p>
<pre>
<?php
$filterObj = new trails();
$filterResult = $filterObj->filterByLocation("city", "Albuquerque", 0, 6, "Array");
echo json_encode($filterResult, JSON_PRETTY_PRINT);
?>
</pre>
<h3>Translations</h3>
<p>Notice that the JSON response for trail requests includes available translations under the key <code>translations</code>. In the request illustrated above, Spanish (es) is listed as an available translation. In order to retrieve this translation, we will send a <code>GET</code> request: <code>GET <?php
echo $baseurl;
?>
api/translation/?id=2&lang=es</code></p>
<pre>
<?php
echo json_encode($GetTrail->getTranslation("es", "Array"), JSON_PRETTY_PRINT);
?>
