如何将搜索查询显示为格式化文本？

时间：2015-10-11 作者：730wavy

我试图在搜索页面上显示网站访问者搜索查询。表单有自定义字段，因此不显示是否为“搜索”，也不显示任何自定义字段。

我的搜索表单-

<!-- Search Form -->
<section class="searchMain sm2">
<form method="get" id="searchform2" action="<?php echo home_url(); ?>/">
<input type="hidden" class="form-control" name="s" id="s" value="<?php _e(\'Search\', \'framework\'); ?>" />
<div class="search-con">

<!-- Search Row 1 -->
<div class="full-divsn">

<!-- City Taxonomy Search -->
<div class="search-field myFields-lg">
<label>City</label>
<select name="property_city" class="form-control">
<?php
$terms = get_terms( "city-type", array( \'hide_empty\' => 0 ) );
 $count = count($terms);
 if ( $count > 0  ){
echo "<option class=\'button\' value=\'City\'>All</option>";
     foreach ( $terms as $term ) {
         echo "<option class=\'button\' value=\'" . $term->slug . "\'>" . $term->name . "</option>";
     }
 }
?>
  </select>
</div>
<!-- End City Taxonomy Search -->

<!-- Search State Custom Field -->
<div class="search-field myFields-xxmd">
<label>State</label>
<select name="property_location" class="form-control">
<option value="Any">Any</option>
  <?php
  $metakey = \'imic_property_site_state\';
  $statez = $wpdb->get_col($wpdb->prepare("SELECT DISTINCT meta_value FROM $wpdb->postmeta WHERE meta_key = %s ORDER BY meta_value ASC", $metakey) );
  if ($statez) {
    foreach ($statez as $states) {
      echo "<option value=\\"" . $states . "\\">" . $states . "</option>";
    }
  }
  ?>
  </select>
</div>
<!-- End Search State Custom Field -->

<!-- Search Price Custom Field -->
<div class="search-field myFields-md">
 <label><?php _e(\'Price\', \'framework\'); ?></label>
                                <input type="text" name="min_price" class="form-control" placeholder="<?php _e(\'Any\', \'framework\'); ?>">
                          </div>
<div class="search-field myFields-txt">
<label>&nbsp;</label>
<div class="form-control">to</div>
</div>

<div class="search-field myFields-xmd-n">
                                <label>&nbsp;</label>
                                <input type="text" name="max_price" class="form-control" placeholder="<?php _e(\'Any\', \'framework\'); ?>">
</div>
<!-- End Search Price Custom Field -->

</div>
<!-- End Search Row 1 --> ....................

            }else {
               $s = $_GET[\'s\'];
                 if ($s == __(\'Search\', \'framework\')) {
                      $query->set(\'s\', \'\');
                $query->set(\'post_type\', \'property\');
            }else{
             $query->set(\'post_type\', \'property\');    
            } }

            }
          return $query;
    }
# Add Filters
if(!is_admin()) {
   add_filter(\'pre_get_posts\', \'imic_search_filter\'); }
       }
在我的搜索中。php我有这个显示帖子数量和搜索查询？s=搜索-

<h4><?php $num = $wp_query->post_count; if (have_posts()) : ?>You have <?php echo $num; ?> search results in <?php echo get_search_query(); ?><?php endif;?></h4>
在同一页上，这是我使用的循环--

<?php
                    if (have_posts()) : while (have_posts()):the_post();?>
                        <?php get_template_part(\'search\',\'property\'); ?>


                    <?php
                   endwhile; endif; wp_reset_query();
                    ?>
再一次，我的查询字符串如下所示。。。。但很明显，它会根据用户的标准而变化--

/?s=Search&property_city=las-vegas&property_location=Nevada&min_price=20000&max_price=500000&beds=2&baths=3&min_area=1000&max_area=1000000&property_type=apartment&s=Search&apor=Any&apvr=Any&post_type=property
那么，如何才能将所有搜索值显示为格式化文本呢？

这就是我一直在寻找的答案-

echo isset( $_GET["s"] ) ? esc_attr( $_GET["s"] ) : \'\';

SO网友:Aric Watson

您可能需要过滤掉一些参数，更改它们的显示顺序，等等，但这应该让您开始：

$s = "/?s=Search&property_city=las-vegas&property_location=Nevada&min_price=20000&max_price=500000&beds=2&baths=3&min_area=1000&max_area=1000000&property_type=apartment&s=Search&apor=Any&apvr=Any&post_type=property";
parse_str($s,$parts);
foreach ($parts as $key => $value) {
    $name = ucwords(str_replace("_"," ",$key));
    echo "$name: $value<br />\\n";
}
你可以使用foreach ($_REQUEST as $key => $value) { 除非有特殊原因你不使用$_REQUEST.
