我重新审视了您的代码,例如在短代码函数中,内容应始终返回而不是回显。
我已将短代码重命名为更好、更短的内容……并为两个下拉菜单启用了 select2。
功能代码:
add_shortcode( 'new_search', 'new_filter_search_shortcode' );
function new_filter_search_shortcode( $atts ) {
extract( shortcode_atts( array(
'taxonomy' => 'product_cat', // Product category taxonomy (by default)
), $atts ) );
ob_start(); // Start buffering
?>
<link href="https://cdn.jsdelivr.net/npm/select2@4.1.0-beta.1/dist/css/select2.min.css" rel="stylesheet" />
<form name="myform" method="GET" action="<?php echo esc_url(home_url('/')); ?>">
<?php
if (class_exists('WooCommerce') ) {
if(isset($_REQUEST[$taxonomy]) && ! empty($_REQUEST[$taxonomy])) {
$optsetlect = esc_attr($_REQUEST[$taxonomy]);
} else {
$optsetlect = 0;
}
$class = 'cate-dropdown hidden-xs';
wp_dropdown_categories( array(
'show_option_all' => esc_html__( 'Make / Model', 'woocommerce' ),
'orderby' => 'name',
'child_of' => 142,
'hierarchical' => 1,
'echo' => 1,
'depth' => 2,
'show_count' => 1,
'value_field' => 'name',
'selected' => $optsetlect,
'taxonomy' => $taxonomy,
'name' => 'model',
'class' => $class,
) );
wp_dropdown_categories( array(
'show_option_all' => esc_html__( 'Year', 'woocommerce' ),
'orderby' => 'name',
'child_of' => 69,
'hierarchical' => 1,
'echo' => 1,
'depth' => 2,
'show_count' => 0,
'value_field' => 'slug',
'selected' => $optsetlect,
'taxonomy' => $taxonomy,
'name' => 'year',
'class' => $class,
) );
}
$search_text = esc_html__('Search', 'woocommerce');
?>
<button type="submit" title="<?php echo $search_text; ?>" class="search-btn-bg"><span><?php echo $search_text;?></span></button>
</form>
<?php
// Enable select2 for both dropdowns
if (class_exists('WooCommerce') ) {
?>
<script>
jQuery(function($){
$('select#model').select2();
$('select#year').select2();
});
</script>
<?php
wp_enqueue_script( 'select2' );
}
return ob_get_clean(); // return buffered content
}
代码位于活动子主题(或活动主题)的functions.php 文件中。经过测试并有效。
用法: [new_search]或echo do_shortcode('[new_search]'); (在 PHP 代码中) .
