Using ISSET with checkboxes

I am working on a Wordpress search form to refine my current search, and what I'm trying to do is search results page with search and values ​​set based on the query.

So far I have managed to do this with separate drop-down lists and separate flags, for example:

<!-- SINGLE SELECT -->
    <select name="baths" class="form-control">
    <?php if (isset($_GET['baths'])) {
        $bths = $_GET['baths']; ?>
    <option value="<?php echo $bths; ?>"><?php echo $bths; ?></option>  
    <?php } else { ?>
    <option value="Any">Any</option>
    <?php } ?>
    <option value="Any">Any</option>
    <option value="1">1+</option>
    <option value="2">2+</option>
    <option value="3">3+</option>
    <option value="4">4+</option>
    <option value="5">5+</option>
    <option value="6">6+</option>
    <option value="7">7+</option>
    <option value="8">8+</option>
    <option value="9">9+</option>
    <option value="10">10+</option>
    </select>

<!-- SINGLE CHECKBOX -->
<input type="checkbox" name="dogs" class="styled" value ="yes" <?php if (isset($_GET['dogs'])) { ?>checked<?php } ?>>

This works, but for a few values ​​it is not. This is my function for creating a set of flags for choosing amenities -

<?php
$amenity_array = array();
$id            = get_query_var('site');
if (!empty($id)) {
  $property_amenities = get_post_meta($id, 'imic_property_amenities', true);
  global $imic_options;
  foreach ($property_amenities as $properties_amenities_temp) {
    if ($properties_amenities_temp != 'Not Selected') {
      array_push($amenity_array, $properties_amenities_temp);
    }
  }
}
global $imic_options;
if (isset($imic_options['properties_amenities']) && count($imic_options['properties_amenities']) > 1) {
  foreach ($imic_options['properties_amenities'] as $properties_amenities) {
    $am_name = strtolower(str_replace(' ', '', $properties_amenities));
    $check   = '';
    if (in_array($properties_amenities, $amenity_array)) {
      $check = 'checked="checked"';
    }

<!-- HERE I TRY TO FIND THE SELECTED CHECKBOXES AND CHECK THEM OFF -->
    if (isset($_GET['p_am'])) {
      $ams = $_GET['p_am'];

      echo '<div class="checkbox"><input type="checkbox" name="p_am" ' . $check . ' class="styled" value ="' . $properties_amenities . '"><label for="' . $am_name . '">' . $properties_amenities . '</label></div>';
    } else {
      echo '<div class="checkbox"><input type="checkbox" name="p_am" ' . $check . ' class="styled" value ="' . $properties_amenities . '"><label for="' . $am_name . '">' . $properties_amenities . '</label></div>';
    }
<!-- END ISSET -->

  }
} else {
  _e('There is no Properties Amenities', 'framework');
}
?>

To select multi select, I use multestlect bootstrap, so on my template the code looks like this:

<select name="property_type[]" id="pt-multi" class="form-control multi-select2" multiple="multiple">
<?php
 $terms = get_terms( "property-type", array( 'hide_empty' => 0 ) );
 $count = count($terms);
 if ( $count > 0  ){
   echo "<option value='Any'>All</option>";
   foreach ( $terms as $term ) {
     echo "<option value='" . $term->slug . "'>" . $term->name . "</option>";
   }
 }
?>
</select>

On the page, it appears as ---

<select name="property_type[]" id="pt-multi" class="form-control multi-select2 iOSselect" multiple="multiple" style="display: none;">
  <option value="Any">All</option>
  <option value="co-op">Co-Op</option>
  <option value="condo">Condo</option>
</select>

<div class="btn-group" style="width: 100%;">
  <button type="button" class="multiselect dropdown-toggle btn btn-default form-control multi-select2" data-toggle="dropdown" title="Property Type" style="width: 100%; overflow: hidden; text-overflow: ellipsis;">
  <span class="multiselect-selected-text">Property Type</span> 
  <b class="caret"></b></button>
  <ul class="multiselect-container dropdown-menu pull-right">
    <li class="multiselect-item multiselect-all">
      <a tabindex="0" class="multiselect-all">
        <label class="checkbox"><input type="checkbox" value="multiselect-all">  Select all</label>
      </a>
    </li>
    <li>
      <a tabindex="0"><label class="checkbox">
        <input type="checkbox" value="Any"> All</label>
      </a>
    </li>
    <li>
      <a tabindex="0"><label class="checkbox"><input type="checkbox" value="co-op"> Co-Op</label>
      </a>
    </li>
    <li>
      <a tabindex="0"><label class="checkbox"><input type="checkbox" value="condo"> Condo</label>
      </a>
    </li>
  </ul>
</div>

Any ideas?

UPDATE

Using my code above, my convenience checkbox is displayed on the page, and so ---

<div>
  <label>amenities</label>
  <div class="checkbox">
    <input type="checkbox" name="p_am" class="styled" value="Doorman (Full Time)">
    <label for="doorman(fulltime)">Doorman (Full Time)</label>
  </div>

  <div class="checkbox">
    <input type="checkbox" name="p_am" class="styled" value="Doorman (Part Time)"><label for="doorman(parttime)">Doorman (Part Time)</label>
  </div>

  <div class="checkbox">
    <input type="checkbox" name="p_am" class="styled" value="Laundry (In-Unit)"><label for="laundry(in-unit)">Laundry (In-Unit)</label>
  </div>

  <div class="checkbox">
    <input type="checkbox" name="p_am" class="styled" value="Fitness Center"><label for="fitnesscenter">Fitness Center</label>
  </div>
</div>

This works with my search function, which allows users to check which amenities to include in the query string -

p_am=Doorman+%28Full+Time%29&p_am=Indoor+Pool

, -

$amenities = isset($_GET['p_am'])?$_GET['p_am']:'';
$amenities = ($amenities == __('Any', 'framework')) ? '' : $amenities;

// .....

if (!empty($amenities)) {
  array_push($meta_query,array(
    'key' => 'imic_property_amenities',
    'value' => $amenities,
    'compare'=>'LIKE'
  ));
}

<?php 

$taxonomyName = "city-type";

$parent_terms = get_terms( $taxonomyName, array( 'parent' => 0, 'orderby' => 'slug', 'hide_empty' => false ) );

echo "<select name='property_nhb[]' class='form-control multi-select' id='p-nhb' multiple>";

foreach ( $parent_terms as $pterm ) {
 // echo "<option data-val='" . $pterm->slug . "' value='Any' " . $selected . ">Any</option>";
    //Get the Child terms
    $terms = get_terms( $taxonomyName, array( 'parent' => $pterm->term_id, 'orderby' => 'slug', 'hide_empty' => false ) );
    foreach ( $terms as $term ) { 

if(isset($_GET['property_nhb[]'])) {
$pnhb = $_GET['property_nhb'];

$selected = 'selected';

}

        echo "<option data-val='" . $pterm->slug . "' value='" . $term->slug . "' " . $selected . " >" . $term->name . "</option>"; 
    }
}
echo "</select>"; 
?>

Your checkboxes have the same name. Try adding another name or using "p_am []" to treat them as an array.
