我正在尝试创建自定义分类法。php页面，我的用户可以在该页面中优化搜索。我尝试创建一种循环，如：

<?php 
                if(!empty($_GET[\'ending\']))
                {
                    $ends = array(
                        \'key\' => \'ending\',
                        \'value\' => (current_time(\'timestamp\', 0) + 3600*24*$_GET[\'ending\']),
                        //\'type\' => \'numeric\',
                        \'compare\' => \'<\'
                    );
                }
                if(!empty($_GET[\'budgets\']))
                {
                    $budgets = array(
                        \'key\' => \'budgets\',
                        \'value\' => $_GET[\'budgets\'],
                        //\'type\' => \'numeric\',
                        \'compare\' => \'=\'
                    );
                }
                $taxonomy = get_query_var(\'taxonomy\');
                $post_per_page = 10;
                $args = array(
                    \'post_type\' => \'project\',
                    \'order\' => \'DESC\', 
                    \'orderby\' => \'date\', 
                    \'posts_per_page\' => $post_per_page,
                    \'paged\' => 1, 
                    \'meta_query\' => array($closed, $ends, $budgets ),
                    \'s\'=> GET(\'keyword\'),
                    \'post_status\' =>array(\'publish\'),
                    \'tax_query\' => array(
                    array(
                        \'taxonomy\' => $taxonomy,
                        \'field\' => \'slug\',
                        \'terms\' => $term->slug
                        )
                    )
                );
                query_posts($args);

                if ( have_posts() ): while ( have_posts() ) : the_post();
                    KleeiaDev_get_post(); 
                endwhile; 

                if(function_exists(\'wp_pagenavi\')):
                    wp_pagenavi(); endif;

                wp_reset_postdata();

                else:
                    echo __(\'No projects posted here yet.\',"KleeiaDev");
                endif;

                wp_reset_query();
                ?>

应该过滤查询的我的元素有$ends, $budgets 和\'s\'=> GET(\'keyword\') 它们与我的侧型相连，如下所示。

<form method="get" action="<?php echo $lnk ?>">
                        <div class="col-sm-12">
                            <input type="text" placeholder="<?php _e(\'Type something here\',\'KleeiaDev\') ?>" value="<?php echo stripslashes($_GET[\'keyword\']) ?>" name="keyword" size="30" class="form-control" />
                        </div>
                        <div class="col-sm-6 col-md-12">
                            <?php echo ProjecTheme_get_budgets_dropdown($_GET[\'budgets\'], \'form-control top-15\' , 1); ?>
                        </div>
                        <div class="col-sm-6 col-md-12">
                            <select name="ending" class="form-control top-15">
                                <option value=""><?php _e(\'Ending in\',\'KleeiaDev\') ?></option>
                                <option value="1" <?php echo ($_GET[\'ending\'] == 1 ? \'selected="selected"\' : \'\') ?>><?php _e(\'1 day\',\'KleeiaDev\') ?></option>
                                <option value="7" <?php echo ($_GET[\'ending\'] == 7 ? \'selected="selected"\' : \'\') ?>><?php _e(\'7 days\',\'KleeiaDev\') ?></option>
                                <option value="30" <?php echo ($_GET[\'ending\'] == 30 ? \'selected="selected"\' : \'\') ?>><?php _e(\'30 days\',\'KleeiaDev\') ?></option>
                                <option value="180" <?php echo ($_GET[\'ending\'] == 180 ? \'selected="selected"\' : \'\') ?>><?php _e(\'6 Months\',\'KleeiaDev\') ?></option>
                            </select>
                        </div>
                        <div class="col-sm-6 col-md-12">
                            <input type="submit" name="apply_filters" class="submit_green top-15 full_width text-center" value="<?php _e(\'Refine search\',\'KleeiaDev\') ?>" />
                        </div>
                    </form>

我的目标是在两个固定条件下优化结果：$taxonomy && $closed [在$分类法中所有$关闭的帖子]+最终[$预算和关键字和$结束]。当我提交时，表单会生成一个url，如mydomain.com/?keyword=hello&budgets=&ending=7&apply_filters=Refine+search 但我总是在没有应用过滤器的情况下得到该分类法的所有结果。我不知道如何继续，因为我不太擅长提问。我读过query_posts 抄本部分没有进一步说明。

\'meta_query\' => array(
                    \'relation\' => \'AND\',
                    $closed, 
                    $ends, 
                    $budgets, 
                ),
