我是PHP和WordPress的新手。我正在使用2个下拉列表,一个用于过滤器类别,另一个用于按目的排序。对于排序和过滤,我没有使用任何钩子。以下代码用于过滤和排序方式实现,以及我用于下拉菜单的另一个代码段:
if($categoryFilter && $categoryFilter == 'all' && $searchKey == '' ) {
$order = 'DESC';
if($sortbyFilter == 'best_match') $order = 'ASC';
$args = array(
'post_type' => array('auction-detail','lot','asset'),
'post_status' => 'publish',
'orderby' => 'date',
'order' => $order,
'posts_per_page' => 10,
'paged' => $paged
);
query_posts( $args );
}
if($categoryFilter && $categoryFilter != 'all' && $searchKey == '' ) {
$sortbyFilter = 'newly_listed';
$_POST['sortby-filter'] = $sortbyFilter;
$args = array(
'post_type' => array('lot','asset'),
'post_status' => 'publish',
//'orderby' => 'post_title',
//'order' => 'ASC',
'posts_per_page' => 10,
'paged' => $paged,
'tax_query' => array(
array(
'field' => 'slug',
'terms' => $categoryFilter,
'taxonomy' => 'category'
)
)
);
query_posts( $args );
}
<div class="filterCols category">
<select id="selcategories" name="category" onchange="handleChange()">
<option value='all' <?php echo (isset($categoryFilter) && $categoryFilter
== 'all') ? 'selected="selected"' : ''; ?>>All</option>
<option value='commercial_trucks' <?php echo (isset($categoryFilter) &&
$categoryFilter == 'commercial_trucks') ? 'selected="selected"' : ''; ?
>>Heavy Machinary</option>
<option value='farm_machinery_implements' <?php echo
(isset($categoryFilter) && $categoryFilter ==
'farm_machinery_implements') ? 'selected="selected"' : ''; ?>>Farm
Equipment</option>
<option value='na' <?php echo (isset($categoryFilter) && $categoryFilter
== 'na') ? 'selected="selected"' : ''; ?>>Construction Equipment</option>
</select>
<input hidden name="category-filter" id="category-filter" type="text"
value="<?php echo $_SESSION['category']; ?>" />
</div>
Below is clear filter div :
<div class="filterCols sortby clearBtnWrapper">
<i class="fa fa-refresh" ></i><a href="#">Clear All</a></div>
我已经尝试过remove_all_filters(),但是由于没有钩子,所以运气不佳。有什么办法吗?

我没有看到“清除过滤器”按钮,也没有看到问题中的第二个选择,但是如何使用类似的东西:
<button onclick="clearFilters()">CLEAR FILTERS</button>
然后在您的.js或内联脚本中
function clearFilters(){
jQuery('#selcategories').val('all');
jQuery('#sortbyFilter').val('all');
}
